As a professional drone service provider, Autel Robotics' launch of enterprise drones has affected the entire drone market and brought huge competition. In the list of commercial drones, Autel Robotics has a total of five drones, namely Autel EVO II Dual 640t, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise .
Don't know enough? We will explain from the following angles.
1. Both have a foldable design and the color is orange.
- The propeller blades used by the EVO II enterprise will be longer and can replace the propeller blades of the EVO II RTK series, but it will affect the battery life.
- EVO II RTK series drones cannot use the propeller blades of EVO II enterprises, which will affect the motor load and cause safety accidents.
The EVO II RTK series supports 36 minutes of flight in a windless environment, and the EVO II Enterprise RTK also has a battery life of 36 minutes in a windless environment, but the EVO II Enterprise can carry different loads. Therefore, the flight time can reach 42 minutes with no load, 38 minutes with night lights, 29 minutes with searchlights, and 34 minutes with megaphones.
Both the EVO II RTK series and the EVO II Enterprise series include two drones, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise. EVO II Pro carries 6k Camera, the EVO II Dual 640T carries an 8k camera and thermal imager.
Image Transmission Performance
The EVO II RTK series supports 9 kilometers of image transmission, and the EVO II enterprise series supports up to 13 kilometers of image transmission.
RTK Module Difference
Both the EVO II RTK series and the EVO II Enterprise RTK use the same RTK module to achieve centimeter-level precise positioning with the same positioning accuracy. At the same time, the two also support network RTK, support PPK, and include microsecond time synchronization.
The EVO II RTK series is no different from the EVO II enterprise RTK connection. It needs to be connected through the APP. The remote control obtains the real-time differential data of RTCM3.0/RTCM3.1/RTCM3.2 through the local map transmission connection or 4G network.
RTK Base Station Mode
The EVO II RTK series uses the same base station model as the EVO II Enterprise RTK.
There are three supported RTK base station modes:
- Support remote control to connect to local RTK base station (A-RTK high precision positioning system) ( RTCM 2.X/3.X );
- Support the remote control to connect to the default network RTK service (RTCM3.2) through the 4G network; (free for the first year in China, and purchase for the second year);
- Support custom network RTK service based on N-Trip account connection (RTCM3.0/RTCM3.1/RTCM3.2)
Both EVO II RTK series and EVO II Enterprise RTK use the same RTK module, so the format of the file record is the same, with the following file formats:
- EVENTLOG.bin is the exposure timestamp log file in binary format;
- PPKRAW.bin is the mobile terminal satellite observation data and ephemeris data in RTCM3.2 MSM5 format;
- Rinex.obs is the transcoded Rinex observation file;
- Timestamps.MRK is the clear exposure timestamp in ASCII format, the location result of each photo at the time of taking the photo, the location status at the time of taking the photo, the standard deviation of the location, and the record file such as the time of taking the photo.


This allows a user to connect to one FTP server, then ask that files be sent to a third-party server. Simply it asks the FTP server to send a file to each interesting port of a target host in turn. The error message will describe whether the port is open or not. This is a good way to bypass firewalls, because organizational FTP servers are often placed where they have more access to other internal hosts than any old Internet host would. It takes an argument of the form <username>:<password>@<server>:<port>. <Server> is the name or IP address of a vulnerable FTP server.
A first possible root cause of the failed deployment of the parachutes was announced in an October 14 press release. Lockheed Martin had built the system with an acceleration sensor's internal mechanisms wrongly oriented (a G-switch was installed backwards), and design reviews had not caught the mistake. The intended design was to make an electrical contact inside the sensor at 3 g (29 m/s²), maintaining it through the maximum expected 30 g (290 m/s²), and breaking the contact again at 3 g to start the parachute release sequence. Instead, no contact was ever made.


As we all know, the wi-fi hotspots at some truck stops have pretty poor signal strengths particularly if you are parked in the back of the lot. Well here is a possible solution to this problem; the Super Cantenna by Wireless Garden, Inc.
The Super Cantenna is a directional 2.4 Ghz wireless network antenna that can be connected to a wireless router, access point or network card as long as they have a removable antenna or an external antenna jack. Of course, most laptops do not have a removable antenna nor do they have an external antenna jack but there are several types of wireless network cards, including PC Cards or USB, that you can get and use with the Super Cantenna.
One reviewer (http://www.notebookreview.com/default.asp?newsID=2859) was able to access his home wireless network from 1.2 miles away. Now the range is going to depend on what is between you and the access point but any improvement is better than nothing.
The Super Cantenna retails for $39.99 from their web site (http://www.cantenna.com/). You may also need a wireless card to allow you to hook the Cantenna up to your laptop but they aren't that expensive either.
Here is some information that I found over at B&H Photo and Video
The Super Cantenna from Wireless Garden is a powerful directional antenna that is designed for use with 802.11b/g wireless networks. The antenna features a tight 30° signal pattern, allowing for much further range than traditional omnidirectional networking antennas. This allows you to connect to public hotspots or to eliminate dead spots in your home network.
• Targeted Long Range Signal
The Cantenna produces a targeted 30° signal that can be used to transmit and receive data over much longer distances than traditional omnidirectional wi-fi antennas. This is ideal for users who would like to connect to a public hotspot for Internet connectivity or create a shared network with neighbors.
• Eliminate Dead Spots
There are some areas of your home where traditional antennas will simply not reach. You can use the Cantenna to better target your wireless signal, eliminating dead spots and providing more complete wireless coverage for your home or home office.
• Better Than a Pringles Can
Many hobbyists have handcrafted antennas similar to the Cantenna using Pringles potato chip cans. The Cantenna takes that concept and applies careful engineering, for a much more practical antenna solution. Not only is the Cantenna fabricated from lab-tested materials, it includes a professional tripod and RF connectors for a hassle-free installation.
I haven't tried the Super Cantenna YET but you can bet I will. If you've tried one or if you end up trying one, let me know what you think.
Here are some links to some other reviews:
I got tired of the wifi so I went with the air card from Sprint. Now I can be online almost anyplace. As long as there is a cell tower in range I can surf the web. I can be at a shipper or receiver or anyplace in between and not worry about getting kicked off like happens allot at the truckstops wifi.

What kind of plan do you have with Sprint? I know that Verizon's "unlimited" plan really isn't unlimited. Once you reach 5GB transfer they downgrade the speed. If all you are doing is surfing and e-mail, 5GB isn't a problem, but if you do any videos or cam then that can eat away at 5GB pretty quickly. Me, I'm considering going with both. Use the air card when I can't get a wi-fi signal (I should say a reliable signal) and us the wi-fi for any data intensive stuff like sending a video message or something.
Comment By: Truckin Tedybehr on Thu, May 01 2008 @ 12:19 PM [EST]
We have unlimited use and we do mainly use it for surfing and emails. It's handy for keeping track of the weather. I check radars when I know I'm heading toward possible bad weather. Some of the wifi sites at the truck stops will actually kick you off after using so much. Even though you paid for so many hrs or days. Even with just surfing the web you can get kicked off. Thats why I quit using the wifi. Most of the wifi's out on the road only have room for so many users so you will find you can't get on even though you have a good signal.

Connection problems with Intel Centrino Advanced-N 6230 and Linksys WRT54G router
Using my new Dell XPS 15 (LX502) with an Intel Centrino Advanced-N 6230 wireless card I couldn't connect to my WRT54G router running the Tomato firmware anymore. Neither WPA nor WPA2 worked, not even WEP. Turns out that I had "Afterburner" mode enabled, which seems to cause problems, as also described here. After disabling this feature in the Tomato interface, everything worked nicely again.

Mobicast has become Vietnam’s second active MVNO following a service launch covering Hanoi.
Branded as Reddi, the service is offered via Vinaphone’s network. Mobicast aims to expand coverage to industrial zones across nine cities and provinces across Vietnam.
Mobifone was granted its MVNO licence last year by the country’s Ministry of Information and Communications. It enters the market alongside Indochina Telecom, which began offering services in April after becoming receiving Vietnam’s first MVNO licence.
Indochina Telecom’s services also use infrastructure operated by Vinaphone, which is a subsidiary of state-run VNPT. A further four operators are active in the Vietnamese market: Gtel, Mobifone, Vietnamobile and military-run Viettel.

Cloud Foundry has toyed around with the idea of providing service mesh capabilities to end users for a while. As CF transitions to a Kubernetes-based runtime, it looks like operators will soon be able to bring the full power of Istio & friends to their developers. But what if you aren’t an operator and you want all those features today?
Enter Hashicorp Consul. Consul offers service networking features such as health checking and service discovery whilst also bringing all the service mesh goodness of zero-trust networks, weighted traffic routing and circuit breaking. The best thing about it? You can use these features on (almost) any Cloud Foundry deployment as an end-user.
Through some clever usage of container-to-container networking, sidecars and a little bit of metadata magic, you can deploy Consul and the service mesh sidecars to any application.
Normally in Cloud Foundry, applications talk HTTP via the Gorouter which provides all the TLS and layer 7 routing goodness we’ve come to know and love.
For many years Cloud Foundry has also offered direct TCP routing too, so apps can use non-HTTP protocols, or handle their own TLS termination.
One down side of very early versions of Cloud Foundry was that this approach made it difficult to make apps accessible only within the platform, and to avoid traffic ‘going out and back in’.
Thankfully several years ago container-to-container networking functionality was added to Cloud Foundry so that apps can communicate directly to each other using any protocol required. However, as this method does not include the Gorouter, application developers need to implement their own logging and metrics for these internal requests.
Consul requires a control plane made up of Consul agents running in “server” mode and, optionally, a UI. The Consul control plane can be deployed as Cloud Foundry apps, using the binary buildpack.
It is recommended that you run a minimum of 3 instances for high availability which then communicate to form quorum and elect a leader. For this consensus algorithm to work, each instance needs to be able to uniquely address other instances and be allowed to communicate using TCP and UDP.
We can do this in Cloud Foundry by using internal routes as well as container-to-container networking.
There is a special domain name in Cloud Foundry reserved for applications within the platform:
Applications can be mapped to a route such as
consul-server.apps.internal which all other applications on the platform can use to resolve the IP address of the containers running the
Individual instances can also be queried by prepending the instance index before the domain, e.g.
1.consul-server.apps.internal. This allows applications on the platform to uniquely address other instances which ticks our first box.
Access between applications is denied by default but can be modified by adding network policies to permit traffic on certain port ranges and protocols. By creating network policies between instances of the
consul-server application, we can allow both TCP and UDP traffic for the relevant port ranges.
Once the Consul control plane is up and running, you need some applications to register into a service mesh. This is done in Consul by running a couple of other processes on the application instance:
Cloud Foundry has first class support for running these processes: sidecars. These processes are started within the same container as the
process_types to which they are bound and are monitored using the
process health check type the same way the main application is.
These sidecars could even be seamlessly included via a sidecar-buildpack
By creating Consul services to represent each application, the sidecar proxies can be configured with all dependent services as upstreams. This allows an application to access other applications as if they were local with the proxy looking after service discovery as well as connecting to the upstream service over mutual TLS.
Most objects in Cloud Foundry (e.g. apps, spaces, orgs) can have metadata associated with them. This combination of annotations and labels can be used for attaching useful information such as commit hashes or environment.
By labelling all the applications inside our service mesh, not only can we quickly see and query all applications that belong in the mesh but we can also use that information to ensure that networking is properly configured. The included script checks that all applications which are labelled this way may communicate freely with each other across ports 8000-9000 and both TCP and UDP.
To demonstrate all this working together, we can use HotROD, a set of example microservices usually used to demonstrate Jaeger’s distributed tracing. HotROD is comprised of 4 applications:
Normally these would all be run on a single host - as shown by the fact that the address used for the other services is hard coded! However, by deploying each service as a separate Cloud Foundry app integrated into a Consul service mesh, we can work around this.
The customer, driver and route services can all be registered as upstreams for the frontend service, making them appear as if they are running on the same host as the frontend. With Consul instead proxying all the requests to the backend services to their respective sidecars over mTLS, the microservices can continue to communicate, even when deployed on different hosts.
Whilst this is a pretty neat trick, the real benefits of Consul come now that the applications are embedded into the service mesh. Consul can accept configuration to modify how the service mesh communicates, using the same infrastructure-as-code approach that Hashicorp offers with Terraform. These options include:
Consul has a concept called intentions that can be used to block access between specific application instances. These can be quickly applied and removed without having to restart applications thanks to the Consul agents constantly checking whether requests are permitted.
Whether it is canary deployments or A/B testing, being able to fine tune how traffic is routed to applications is a handy tool to have. Consul has a number of layer 7 traffic management features that make new ways of deploying and running applications possible.
When using container-to-container networking, requests no longer pass through the Gorouter meaning we lose all metrics derived from Gorouter data. Consul proxies can be centrally configured to emit metrics in a number of different ways providing extremely fine grained data even for application-to-application communication.
With Cloud Foundry providing an easy way to run applications with health monitoring, logging and rolling deployments out of the box, even complex deployments are quick to develop. There are still many interesting avenues to explore including security, automating metrics and configurable sidecar buildpacks to leverage other features of Cloud Foundry to make the process easier to set up and manage.
Together with all the Cloud Foundry features we know and love, these powerful new capabilities demonstrate just how flexible of a platform Cloud Foundry has become. Getting this project running took less than two days of work (and was all done on the public, multi-tenant Pivotal Web Services!) - a testament to how easy deploying to Cloud Foundry can be without significant platform customisation.
Running a configurable, zero-trust service mesh on top of Cloud Foundry without any “magic” or fuss - who would have thought?


The 4k Dream
-Delving into the very guts of what makes display technology awesome-
The very last thing I saw as I was researching gear for my 2014 PC workstation build, was information on 4k and 8k video formats as well as what hardware was compliant with either of those standards.
Very little if any hardware beyond some esoteric digital cinema gear unavailable to any but the super rich currently supports 8K video standard for motion pictures or still images (50,000 dollars and up).
N.H.K of Japan was rumored to be transmitting U-HD broadcast video when the rest of the world (especially the US market) is only recently getting fully on board with the HD/1080P bandwagon. U.S. broadcasters are unlikely to adopt 4K any time soon due to the massive restructuring of the bandwidth allocations required for such high bandwidth signaling that the FCC regulates. 4K will make its way into the home for non broadcast uses very soon that much is guaranteed.
What is U-HD you ask? Well I can't really break this down into something a non technical person could appreciate without being able to show them the difference visually but I will give it to you in terms of pixel count.
(8K format is such a high resolution format you would not really notice the difference between it and 4K with the naked eye.)
Broadcast video is currently available in a few formats 480p/720p/1080p, with 720i and 1080i as alternatives (that means interpolated). Older broadcast TV signals used to be 360p.
The actual pixel counts of 4K & 8K vary because it’s calculated based on the total area of the screen its being rendered on.
Most 4k compliant LCD/LED panels powering high end computer monitors and what could be for the time being in the US markets considered rarified, 4K U-HD TV's exist in these formats:
1. 3480 x 2160
2. 5120 x 2160 (Very large display panel TV's and digital cinema screens)
8K display technology does exist but so far none of it has gone beyond being exhibited as C.E.S showroom floor demonstration models. So far the only formats for this are as follows:
1. 7680 × 4320 - Prototype TV at 2013 C.E.S by Sharp
2. 8192 × 8192 - Imax and Planetariums, with a pixel count of 67 megapixels.
How does all this factor into the domain of Photography and Cameras?
4K displays would have the widest Gamut (largest color pallette) possible, meaning Adobe RBG (1999) and sRGB would easily fit within the color space that a display of this quality would support. Pro Photo RGB which has an even wider gamut than this would also work. Web formats almost all generally default to sRGB. Currently only the most expensive 1080p capable screens in existence can handle 98 to 99 percent of the Gamut of the first two formats i’ve mentioned. Some of the Gamut limitations of screens appear to be caused by the transmission cable itself. The most common modern formats available are HDMI, and the format championed early on by Apple called Display Port.
Display Port is a cutting edge super high bandwidth connection standard that has been slow to catch on. It is capable of transmitting audio, video, data and power to be sent through the same cable.
HasselBlad, Leica, Mamiya have all been able to record and reproduce images in 4k for many years now. With Pixel counts in some of these cameras topping out at 200 megapixels, you can see how it is only a matter of time before the rest of the technological world will realize the need to catch up.
If you were curious what parts i’m looking at, This is a brief list of them:

In today’s digital climate, the safeguarding of online transactions has become increasingly paramount. The potential for fraud and data breaches necessitates the development and integration of rigorous security protocols. Among the numerous strategies, online SMS verification has emerged as a popular and robust method for authenticating end-users. By sending a one-time passcode (OTP) to a user’s mobile device, companies can verify the identity of the person attempting the transaction. This additional layer of security is proving invaluable, but what exactly is online SMS verification, and why is its usage proliferating so rapidly?
Defining Online SMS Verification
Online SMS verification is a security measure that involves sending a temporary numeric code to a user’s mobile phone. The user must then input this code on the site or application to complete a registration or authenticate a transaction. The process is simple, cost-effective, and leverages mobile carriers’ infrastructure, making it a popular choice for businesses large and small.
The Ultimate Checkpoint for Verification
In the never-ending battle against fraud, digital businesses have turned to SMS verification as an added layer of defense. Unlike traditional username and password systems, SMS verification codes are dynamic and time-sensitive, greatly reducing the window of vulnerability. Additionally, because the code is sent directly to the user’s mobile phone, it’s much harder for a would-be hacker to intercept, as it requires physical access to the device or the mobile network.
Ease of Integration and User Familiarity
One significant reason for the prevalence of SMS verification is its simplicity and the familiar use of text messaging. Nearly all mobile users are familiar with the process of receiving and entering a verification code via SMS. For businesses, this verification method is easy to integrate into their existing systems, with many opting for APIs that seamlessly handle the SMS sending and verification processes.
Global Accessibility and Regulatory Compliance
SMS verification is a global solution that isn’t bound by the technical limitations of specific regions. With proper carrier support, text messages can be delivered to users anywhere with a cellphone signal. This level of accessibility is crucial for global businesses and services. Furthermore, SMS verification aligns with data protection and privacy regulations like GDPR, as it does not store personal data or create additional data-handling risks for companies.
The Downsides and Growing Alternatives
Despite its many benefits, SMS verification is not without its limitations. SMS can be intercepted, although it’s a much smaller risk than with other forms of communication. The method also depends on the reliability of mobile networks, which can be disrupted. Because of these issues, especially with the rise of sophisticated cyber threats, businesses are exploring alternative verification methods, such as app-based authenticators or biometric verification.
Online SMS verification has become an integral part of the security infrastructure for a wide array of digital services, from banking apps to social media platforms. It provides a crucial extra layer of defense against unauthorized access and fraud, while maintaining a user-friendly experience. In the face of evolving cybersecurity threats, businesses will continue to innovate and invest in new digital verification methods, but for now, SMS verification remains one of the most effective and widely-adopted tools in the digital security arsenal.


|BBC-Marconi Type A|
|Inventor:||F W Alexander|
|Model:||A, AX, AXB, AXBT|
In the early 1930s, the BBC became aware of RCA's model 44 ribbon microphone that was used in Hollywood. Each pair of microphone and amplifier would have cost the BBC £130 (approximately £6,500 in 2009). As this was not within the BBC's budget, they designed their own microphone, the Type A, alongside Marconi. There were initial concerns that the new design infringed the patent of the RCA microphone, but these were overcome. The Type A was produced at a cost of £9 each (approximately £475 in 2009).
The original Type A microphone was designed by engineer F. W. Alexander under the guidance of H. L. Kirke's Research Department at the BBC.
In 1940, the Type A was used in the broadcast of Charles de Gaulle's 1940 appeals.
In the early 1950s, the BBC began to design the Type A's successor. The first model was the pressure gradient PGD design. In 1953, production began on the PGS (pressure gradient single) ribbon microphone in agreement with Standard Telephones and Cables (STC). In the mid-1970s, STC's manufacturing was transferred to Coles Electroacoustics, who continue to manufacture the PGS under the model number 4038.
Four versions of the microphone were produced - the "A", "AX", "AXB", and "AXBT". The original microphone used a thick aluminium ribbon which produced a harsh resonance. This was soon replaced with a thinner ribbon, and was named Type AX. In 1943, the AXB model was launched, which featured balanced wiring. In 1944, the microphone was renamed the AXBT with the addition of a Ticonal magnet to increase sensitivity by 6 decibels. The AXBT weighed approximately 9.25lb.
The microphone had a figure-of-eight polar pattern. The aluminium ribbon was less than one micrometre thick.


Coaxial cable assemblies are an ideal solution for transmitting RF signals from one connection to the next within a system. They are most often used to connect a Printed Circuit Board (PCBs) to other PCBs but can also be used for I/O connections and to connect external antennas to wireless modules. Assemblies can vary in length from 0.98 inches (25 mm) to 1200 inches (100 feet) with various configurations (female (jack) to female, male (plug) to male, female to male, male to female), orientation (straight, right-angle) and mounting (bulkhead) options. These attributes, along with unique design features, allow standard assemblies to meet the specific design requirements of various applications across markets.
Our line of high-performance precision test cables (ATC-PS) feature additional phase stable and low loss capabilities which makes them ideal for test and measurement laboratory usage. Custom cable assemblies are available and offer a more tailored solution than standard products.

Catalyst Switches for Microsoft Network Load Balancing Configuration Example_百度文库
These sessions can be balanced across the available connections. An FTP application only uses a single session so it is not balanced; however if a secondary FTP connection is made, then it may be balanced so that the traffic is distributed across two of the various connections and thus provides an overall increase in throughput. Additionally, network load balancing is commonly used to provide network redundancy so that in the event of a WAN link outage, access to network resources is still available via the secondary link s.
Redundancy is a key requirement for business continuity plans and generally used in conjunction with critical applications like VPNs and VoIP. Finally, most network load balancing systems also incorporate the ability to balance both outbound and inbound traffic. Inbound load balancing is generally performed via dynamic DNS which can either be built into the system, or provided by an external service or system.
Having the dynamic DNS service within the system is generally thought to be better from a cost savings and overall control point of view. Microsoft has also purchased  a technology that it renamed Network Load Balancing NLB that allows for efficient utilization of multiple network cards.
Microsoft Network Load Balancing on Nexus 7000 Configuration Example
MS NLB was introduced for the first time in Windows NT server to spread traffic over multiple hosts without the need for a hardware based load balancer, e. This setup will cause all incoming traffic for the cluster to be flooded to all ports of the switch as unknown unicast frames:  even to hosts that are not joining in the cluster.
To keep flooding minimal you would need to use a dedicated VLAN for the cluster. Another option is to make NLB in multicast mode.

Do AirPods Have a Microphone?
Yes, AirPods do have a microphone. The microphone is located on the stem of the AirPod and is used for taking phone calls and recording audio. The quality of the microphone is good, but it can be affected by wind noise when used outdoors.
How Does the AirPods Mic Work?
To understand how the AirPods mic works, it's important to know a little bit about how microphones work in general. Microphones convert sound waves into electrical signals. The type of microphone you're using will dictate how these electrical signals are then converted back into sound.
The AirPods mic uses a MEMS (microelectromechanical system) design. This means that the microphone is very small and compact, making it ideal for use in headphones like the AirPods. MEMS microphones are also often used in mobile devices like smartphones.
One advantage of using a MEMS microphone is that they're less susceptible to interference from things like cell phones or other electronic devices. They can also be designed to be more resistant to wind noise, making them a good choice for use in outdoor environments.
So how does the AirPods mic work? When you speak into the microphone, the sound waves vibrate a small diaphragm inside the microphone. This vibration is then converted into an electrical signal. The electrical signal is then sent to your iPhone or other devices, where it's converted back into sound.
The AirPods mic is designed to filter out background noise so that your voice can be heard clearly. This is why it's important to speak directly into the microphone when you're using the AirPods. If you're in a noisy environment, you may need to speak a little bit louder so that your voice can be heard over the noise.
One thing to keep in mind is that the AirPods mic will only work when you're using the headphones. If you're not wearing the AirPods, the microphone will not be able to pick up your voice. This is why it's important to make sure that you're wearing the AirPods before you start speaking.
If you're having trouble with the AirPods mic, there are a few things you can try. First, make sure that you're wearing the AirPods correctly. The microphones are located on the inside of the earbuds, so you'll want to make sure that they're pointing towards your mouth.
Another thing you can try is to clean the microphones with a soft, dry cloth. If you're still having trouble, you can contact Apple for more support.
Is the AirPods Mic Good?
AirPods are a popular choice for headphones, but how good is the microphone?
The AirPods mic is good but not great. It's certainly better than many built-in phone mics, but it doesn't compare to a dedicated external mic. If you're looking for the best possible audio quality, you'll want to use an external mic. However, if you're just looking for a decent mic for everyday use, the AirPods mic will suffice.
Difference between AirPods Mic and AirPods Pro Mic
There are two main types of AirPods: the original AirPods and the newer AirPods Pro. Both types of earbuds have a built-in mic, but there are some key differences between the two that you should be aware of.
The AirPods Pro mic is more powerful and can pick up voices better than the standard AirPods mic. The AirPods Pro also has Active Noise Cancellation (ANC), which means that it can cancel out background noise much better than the regular AirPods.
If you're looking for the best possible audio quality, then you'll want to go with the AirPods Pro. However, if you're on a budget or don't need the extra features, then the regular AirPods will do just fine.
Do AirPods Have Active Noise Cancellation?
Noise cancellation is a feature that's become increasingly popular in recent years, especially in headphones. But what about earphones? Do AirPods have active noise cancellation?
The answer is no. AirPods do not have active noise cancellation. However, they do have a feature called "transparency mode," which allows you to hear your surroundings while still wearing your earphones. This can be useful in certain situations where you need to be aware of your surroundings (e.g., while walking or running outdoors).
The AirPod microphone is designed to work in conjunction with the built-in sensors in the earbuds. The microphones use these sensors to identify when you are speaking and adjust the audio accordingly. This helps to reduce echoes and ambient noise so that your voice is clearer and more distinct.
In addition, the AirPod earbuds themselves are designed to fit snugly in your ear canal. This helps to create a seal that blocks out external noise, further enhancing the clarity of your voice.
However, when it comes to AirPods Pro, there are three different listening modes it offers: Active Noise Cancellation, Transparency, and Off.
Active Noise Cancellation uses the two microphones in the AirPods to block out external noise. This is great for when you want to focus on your music or podcast without any distractions.
Transparency mode is the opposite of Active Noise Cancellation – it allows you to hear your surroundings while still wearing your AirPods. This can be useful when you're walking or running outdoors or if you want to be able to hear someone talking to you while still listening to music.
The third and final listening mode is Off, which turns off all noise cancellation features.
How To Clean the AirPods Microphones
If you're like me, you probably use your AirPods all the time. And if you're also like me, you probably don't think too much about cleaning them - until they start to sound weird.
Turns out, the mic on your AirPods can get pretty gunked up if you don't clean it regularly. And when that happens, your phone calls and FaceTime chats will start to sound muffled and unclear. Not ideal!
Here is how to clean your AirPods mic and keep it sounding crystal clear.
First things first: grab a soft, lint-free cloth and some isopropyl alcohol (also known as rubbing alcohol). Avoid using anything abrasive, like a paper towel, as this could damage the delicate microphone mesh.
Now gently wipe down the AirPods mic, being careful not to get any liquid inside the actual device. You can also use a cotton swab dipped in rubbing alcohol to clean out any dirt or debris that's built up in the crevices around the mic.
Once you're finished cleaning, make sure to dry off the area completely before putting your AirPods back in your ears. And that's it! A quick and easy way to keep your AirPods sounding their best.

Have you ever wondered what the company that makes the communication system of correction agencies and prisons in the United States is?
There are many enterprises that handle the communication for other corporations, and this is called third-party telecommunication service. For prisons, however, the focus on security has to be tripled, and it must be the biggest priority of the brand providing the telephone service.
Sometimes, on the same note, there needs to exist a way in that communication system for the correction agencies to monitor and inspect past communications and analyze if there are any signs of crimes being committed and secret codes being transmitted through the telephone by inmates.
Because of these many rules and necessary precautions, the communication service provider needs to be specialized in providing for prisons and localities that handle dangerous individuals.
One of the most renowned companies in the business is the Securus Technologies, led by the CEO Rick Smith.
Rick Smith was the President and CEO of the telecommunications corporation Eschelon Telecom, so he has a long history of expertise in the business. Read more on PRNewsWire.com.
The firm was founded in 1998, and it was meant to provide innovative solutions and third-party accessibility to their telecommunications to their clients and partners.
A few years later, Rick Smith saw the necessity of having a specialized telecom company for prisons and correction departments, because law enforcers were struggling to find a call center service that could provide extensive security in their system and allow monitoring of past calls whenever it was needed.
Securus Technologies was then born in 2008 as a solution for these departments to handle the telephone communication of inmates with their families and friends.
Since that time, Rick Smith has led many innovative changes that have made the company truly stand out in the business because of their focus on finding modern ways to implement their system into the agencies. In other words, Securus Technologies was one of the first prison-specialized telecom providers to ever delve into the smartphone system to be possibly used in these correction localities with the full security of a telephone service. It has been received with great feedback.
The other primary objective that is extremely necessary for a communication service in prisons is a way of controlling the entire telephone system from inside the administration office of that facility. For example, there are phones that inmates can utilize to call their parents and friends. There needs to be a way for the agents of that facility to directly monitor the calls from an office because there are many inmates to utilize the phones at the same time.
Rick Smith, understanding the necessity of a customized technology, has included both objectives into a single product. More than a hundred facilities around the United States are utilizing the services of Securus Technologies.
Rick Smith has developed a service that has acquired tons of positive feedback throughout the years. Rick Smith has developed a service that has acquired tons of positive feedback throughout the years.

Traffic Signal Coordination
The City of Peoria attempts to coordinate the traffic signals to provide safe and efficient traffic flow throughout the City. The ability to provide good coordination on a corridor is generally a function of signal spacing, prevailing traffic speed, amount of traffic, roadway capacity, signal cycle lengths, and conflicts with other major roadways. Not only does traffic signal coordination serve the greater good of the traveling public, but also has the added benefit of reducing fuel consumption and emissions because it reduces overall traffic delays.
In addition, except for in the Central Business District, most Peoria traffic signals use video or pavement loop detection systems to actuate the signal timing. This allows the signal to adjust the length of a phase of traffic, such as a left turn, to accommodate the current traffic load. This type of system helps clear the intersection and reduce the overall traffic delay. Another benefit of actuated signals is that they allow the controller to know when a vehicle from the side street approaches the intersection, which is particularly important at night because it allows the signals to maintain green signals on the main road and only call for the side street green to be activated when needed.
A majority of the signals in Peoria are coordinated, however, some are not. Signals that are in isolated locations or in too tight of a network do not lend themselves to good coordination. These intersections are often run in a free mode and change on the demand of traffic volumes. In the downtown area, where the streets are laid out in a grid fashion, it has been found that the signals run more efficiently pre-timed with short cycle lengths. The downtown intersections are still coordinated on some of the streets that have good progression, however, on other downtown streets, that do not have good progression because of the close proximity of the intersections, they are not coordinated.

Imagine a world where you don"t have to dig up the earth to lay down co-axial cable lines, or where accessing the internet means plugging a small black box into a power outlet in your house. That world may be around the corner. Thanks to the Broadband over Power Lines (BPL), a technology, that threatens to turn the communications world upside down by bolstering broadband competition, lowering consumer prices and wiring rural India.
The key to broadband over power lines technology lies in a long established scientific fact that radio frequency (RF) energy can be bundled on the same line that carries electrical current. Since RF and electricity vibrate on different frequencies, there's not going to be any interference between the two. As such, data packets transmitted over RF frequencies are not overwhelmed or lost because of electrical current.
Model Link: Connecting To Net Over Powerlines
Non-intrusive equipments that convert electric sockets to broadband access points
bandwidth transfer rates across electrical grids led to huge advances. In India, the Indian Institute of Information Technology (IIIT), Allahabad, has successfully tested BPL. Jamia Milia Islamia, New Delhi plans to use BPL during the Commonwealth Games 2010 to capture the hairline differences in track and field events that would decide the winner.
However, its most significant undertaking -one that promises to revolutionise communications in the country much like the ubiquitous STD booths did more than a decade ago - is to wire rural India.
The technology could be a life-saver for schools, hospitals as well as internet kiosks which could relay invaluable information about crop prices and weather patterns.
Consequently, a BPL pilot project has been started in villages within 3-10 km of Amethi and Allahabad, all of which have power, but no telephone or internet connectivity. No company will lay down co-axial cable here because the business would be unsustainable, but the BPL solution would cost much less. "The cost of the wireless and this technology is almost the same; hence, both can be adopted according to the terrain;" says B.B. Bhatia, vice-president of Telecom Equipment Manufacturers Association (TEMA).
"It (BPL) is a proven technology and can be a boon for the rural parts of the country," says Ravinder, chief of engineering at Central Electricity Regulatory Commission (CERC). "However, the economics of its commercial applications need to be established.”
Not everyone is so upbeat about BPL. Critics stress that talk of the technology has been around for years, with nothing to show for it. "BPL does not hold promise at a time when Wi- Fi and WiMax are on the prowl," says Joel Perlman, president and co-founder of Copal Partners, a London-based financial analytics and Research Company. "It has potential but has to survive strong competition from other technologies," agrees Vijay Madan, executive director at Centre for Development of Telematics. "Further, a number of technical issues need to be resolved."
Another charge levied against BPL is that power lines are great radiators of the frequencies that BPL occupies. Copper wires, co-axial cable, and fiber are all non-radiating, self-shielded mediums, but power lines act like natural antennae and can "lose" the BPL signal in the air. Consequently, it remains to be seen if the government will allow BPL to thrive if it inconveniences the military, air force or the aviation industry, all of which heavily use radio frequencies.
BPL also is a little dicey in developing countries such as India where the power situation is in shambles, say critics. When even metros such as Delhi and Mumbai suffer power outages for several hours a day, it is unlikely that too many people will opt for an internet connection that is solely reliant on fickle power transmission.
However, proponents of BPL argue that its benefits far outweigh its drawbacks. In many parts of the world, there is as much as a 30 per cent non-technical loss of power distribution in various areas of the power grid. The BPL project, however, is part of the "Intelligent Grid Network" which utilises advanced technology to remotely monitor power meters. Using a BPL backbone, a utility company is able to deploy a loss detection application that identifies when and where power is being lost.
Offices in corporate India could very quickly embrace a BPL solution despite its drawbacks because of its inherent advantages over Ethernets. Setting up Ethernet LANs involves the breaking of walls or the chiseling of multiple holes in order to snake network cables around the office. Installing external conduits on top of existing construction is often required. This process causes much disruption to an office environment. It mars the aesthetics of the interiors and generates unnecessary additional expenses.
Plug-and-play BPL networks have no such problems. "BPL uses existing electrical power cables or co-axial cables to create an IP network," says Maple Leaf"s Parimoo. "Hence, every power outlet in the network automatically becomes an access point for any IP device. This is not possible in an Ethernet LAN environment.”
Still, BPL has a long way to go to establish its reliability. But for countries such as India, whose rural populace has no access to affordable communication capabilities, BPL technology might just be the solution.

In the second quarter China took over the position once held by the US as the world’s top smartphone market, with 33.1 million handsets in shipments, more than the 25 million handsets shipped in the US.
Since the start of the second quarter China’s smartphone shipments have passed those of conventional mobile phones. In June smartphones accounted for 56.9% of China’s mobile phone market.
The explosive growth is attributed to the introduction of budget-priced smartphones made possible by a sharp drop in hardware costs. Smartphones priced below 1,000 yuan ($157) cost less than 400 yuan ($63) to produce, according to Southern Daily.
Budget smartphones flooded the market during the first half of this year after China Unicom introduced them in the second half of last year, prompting China Mobile and China Telecom follow suit.
China’s smartphone shipments in the first quarter skyrocketed 164% over the same period of last year to 33.1 million handsets, according to data from the US-based asset-management firm Needham & Company.

Jeremy Naydler, Wake Up World
In November last year (2018), the United States Federal Communications Commission (FCC) authorized the rocket company SpaceX, owned by the entrepreneur Elon Musk, to launch a fleet of 7,518 satellites to complete SpaceX’s ambitious scheme to provide global satellite broadband services to every corner of the Earth. The satellites will operate at a height of approximately 210 miles, and irradiate the Earth with extremely high frequencies between 37.5 GHz and 42 GHz. This fleet will be in addition to a smaller SpaceX fleet of 4,425 satellites, already authorized earlier last year by the FCC, which will orbit the Earth at a height of approximately 750 miles and is set to bathe us in frequencies between 12 GHz and 30 GHz. The grand total of SpaceX satellites is thus projected to reach just under 12,000.
There are at present approximately 2,000 fully functioning satellites orbiting the Earth. Some beam down commercial GPS (or ‘SatNav’), some provide TV, some provide mobile phone services, and some bounce radar back and forth to produce images for meteorologists and military surveillance. The Earth is thus already comprehensively irradiated from outer space. But the new SpaceX fleets will constitute a massive increase in the number of satellites in the skies above us, and a correspondingly massive increase in the radiation reaching the Earth from them. The SpaceX satellite fleet is, however, just one of several that are due to be launched in the next few years, all serving the same purpose of providing global broadband services. Other companies, including Boeing, One Web and Spire Global are each launching their own smaller fleets, bringing the total number of projected new broadband satellites to around 20,000 – every one of them dedicated to irradiating the Earth at similar frequencies.
Why this sudden flurry of activity? The new satellite fleets are contributing to a concerted global effort to ‘upgrade’ the electromagnetic environment of the Earth. The upgrade is commonly referred to as 5G, or fifth generation wireless network. It has become customary in tech circles to talk about the introduction of 5G as involving the creation of a new global “electronic ecosystem.” It amounts to geo-engineering on a scale never before attempted. While this is being sold to the public as an enhancement of the quality of video streaming for media and entertainment, what is really driving it is the creation of the conditions within which electronic or “artificial” intelligence will be able to assume an ever-greater presence in our lives.
The introduction of 5G will also require hundreds of thousands of new mini mobile phone masts (also referred to as “micro-cells” or “base stations”) in urban centres throughout Australia, and literally millions of new masts in cities throughout the rest of the world, all emitting radiation at frequencies and at power levels far higher than those to which we are presently subjected. These new masts are much smaller than the masts we currently see beside highways and on top of buildings. They will be discreetly attached to the side of shops and offices or secured to lampposts. The 20,000 satellites are a necessary supplement to this land-based effort, for they will guarantee that rural areas, lakes, mountains, forests, oceans and wildernesses, where there are neither buildings nor lampposts, will all be incorporated into the new electronic infrastructure. Not one inch of the globe will be free of radiation.
Given the scale of the project, it is surprising how few people are aware of the enormity of what is now just beginning to unfold all around us. Very few people have even heard about the 20,000 new satellites that are due to transform the planet into a so-called “smart planet,” irradiating us night and day. In the national media, we do not hear voices questioning the wisdom, let alone the ethics, of geo-engineering a new global electromagnetic environment. Instead, there is a blithe acceptance that technology must continue to progress, and the presence in our lives of increasingly “smart” machines and gadgets that each year become cleverer and more capable is an inevitable part of this progress. And who doesn’t want progress? Almost everyone loves their sleek and seductively designed phones, iPads and virtual assistants, and regards them as an indispensable part of their lives.
The question we should ask is whether we also want increasingly intense exposure of the natural environment and all living creatures, including ourselves, to more and more electromagnetic radiation. Is it likely that this does not entail any adverse health consequences, as both government and industry claim? If the electromagnetic waves that connect our smartphones to the Internet travel through brick, stone and cement, then what happens when these same waves encounter our bodies? Be assured that they do not just bounce off us! They travel into the human body. The degree to which they are absorbed can be precisely measured in what is called the Specific Absorption Rate, expressed in Watts per kilogram of biological tissue. When we fill our houses with WiFi, we are irradiating our bodies continuously. When we hold a smartphone to our ear, electromagnetic waves irradiate our brains. Do we really believe this could be completely harmless?
Waves and Frequencies
At present, mobile phones, smartphones, tablets, WiFi and so on all operate at under 3 GHz in what is called the “microwave” region of the electromagnetic spectrum. If you could see and measure their wavelengths, you would find that they are many centimeters (or inches) long. A smartphone operating at 800 MHz, for example, sends and receives signals with wavelengths of 37.5 centimeters (just under 15 inches). Operating at 1.9 GHz, the wavelengths are 16 centimeters (just over 6 inches). WiFi uses the 2.4 GHz frequency band with 12 centimeter wavelengths (just under 5 inches long).
The introduction of 5G will entail the use of considerably higher frequencies than these, with correspondingly shorter wavelengths. Above 30 GHz, wavelengths are just millimeters rather than centimeters long. The millimeter waveband (from 30 GHz to 300 GHz) is referred to as Extremely High Frequency, and its wavelengths are between 10 millimeters and 1 millimeter in length.3 Up to the present time, Extremely High Frequency electromagnetic radiation has not been widely propagated, and its introduction marks a significant step change in the kind of electromagnetic energy that will become present in the natural environment.
The reason why millimeter waves are to be used for 5G is that much larger bands of spectrum are available in the Extremely High Frequencies than at lower frequencies. This means that there can be much broader “bandwidth.” Broader bandwidth means that larger quantities of data can be transferred and the speed of transfer of the data will be significantly faster. One of the effects of this is that it reduces what is called “latency,” or time-lag, in the system, improving the quality of video streaming. But in so doing, it also enables a greater seamlessness between the data accessible from virtual sources and our perceptions of objects in the real world, as is required, for example, in Augmented Reality applications. Greater seamlessness means that we more effortlessly inhabit the natural and the electronic worlds as if they were a single reality.
One of the technical problems of using frequencies in the millimeter region of the spectrum is that because the waves carrying the data are so tiny, being only millimeters long, they are less able to pass through physical barriers, like walls and trees, than are the longer waves of lower frequencies. This is why it is necessary to have so many more new “micro-cells” or “base stations.” They will need to be spaced at 100 meters apart in cities because beyond this distance their signals weaken and are therefore less able to penetrate buildings and connect with the devices inside. As well as being more closely spaced, the 5G micro-cells will operate at much higher power than current phone masts in order to ensure that the signals are sufficiently strong.
Because the wavelengths are so much smaller, the antennas transmitting and receiving them will also be much smaller than those of current phone masts and electronic devices. A single 5G transmitter/receiver will have a large number of tiny antennas, grouped together in one unit. An array of just over a thousand such antennas measures only four square inches, so will easily fit into a small base station on a lamppost, while the smartphone in your pocket will probably have sixteen.
Both 5G satellites and 5G land-based masts will use a system called the “phased array.” In phased array, groups of antennas are coordinated to radiate pulses in a specific direction and in a specified time sequence. This allows a concentrated beam of radio waves to be exactly aimed at designated targets, to enable signals to be sent or received. Because the beams are concentrated in this way, this adds to their power, which means they are able more easily to penetrate buildings. But it also means that any living creature that gets in the way of such a concentrated beam will be subjected to a powerful dose of extremely high frequency radiant electricity.
A study published earlier this year demonstrated that certain insects, because of their small body-size, are particularly vulnerable to the millimeter waves of the higher frequencies to be utilized by 5G.5 Other studies have shown that bacteria and plants are vulnerable, and so also (as one might expect) are the skin and the eyes of animals including, of course, human beings.6
As well as its ability to concentrate power in focused beams, phased array technology has a further complicating factor. Either side of the main beam, the time intervals between the pulses are different from the time intervals between those of the main beam, but they may overlap each other in such a way as to produce extremely rapid changes in the electromagnetic field. This can have a particularly detrimental effect on living organisms, because instead of the radiation decaying when it is absorbed into living tissue, it can be re-radiated within the body. The moving charges streaming into the body effectively become antennas that re-radiate the electromagnetic field and send it deeper into the organism. These re-radiated waves are known as Brillouin precursors, named after the French physicist Leon Brillouin, who first described them in 1914. Research suggests that they can have a significant and highly detrimental impact on living cells.8
The UN-reassuring Assurances of Government and Industry
The government body charged with advising on the health effects of electromagnetic radiation, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), seeks to reassure us that there is no established evidence that Radio Frequency radiation (which radio, television, mobile phones, smartphones and 5G all use) has any adverse health effects on either adults or children.9 ARPANSA’s advice is largely based on findings derived from the supposedly independent AGNIR (Advisory Group on Non-Ionising Radiation), which advises the UK Health Department.10 AGNIR’s report, published in 2012, on the safety of Radio Frequency radiation stated that there was a lack of “convincing” and “conclusive” evidence for any adverse health effects. It was like giving a blank cheque to the telecommunications industry to move into the higher frequencies without any heed for the consequences.11

As networks were built, these distance considerations were kept in mind. It establishes connections between telephones that are internal to the organization, and it establishes connections between internal extensions and the outside world that is, the PSTN.
Please spread the word. CS Free Differentiate between analog and digital transmission. Analog transmission is capable of being conveyed in a no fewer than four ways: This signal interference is illustrated in Fig.
For example, high-end VoIP phones often contain computer chips to enable them to download and install small software applications so that they can function in many ways like computers.
MP3 players often sample less frequently and use fewer bits per sample to produce smaller transmissions, but the sound quality may suffer.
With PCM, the input voice signal is sampled 8, times per second. Because VoIP phones are digital, they can also contain additional capabilities.
The second prerequisite is the capability to detect errors as they occur and to have some procedure for resolving those errors. Data that is transmitted via digital transmission may be digital messages that have origins for a data source a computer or a keyboard, for example.
One wire is used for transmission of the information. There are versions designed for 8 Kbps circuits which send 1 bit 8, times per second and 16Kbps circuits which send 2 bits 8, times per secondas well as the original 32 Kbps version. Two-pair and four-pair refer to the number of wires in the internal cabling plan.
The core of the MOST standard is a set of 25 or 40 megabit per second fiber-optic cables that run throughout the car. Because VoIP phones are digital, they can also contain additional capabilities. MP3 players often sample less frequently and use fewer bits per sample to produce smaller transmissions, but the sound quality may suffer.
It samples 8, times per second and produces eight bits per sample. This condition is called intersymbol interference.
However, the local loop is increasingly being digitalized, so as we migrate to an end-to-end digital environment, everything becomes four-wire.But I can tell you about some tricks to get a feeling for what we mean by data transmission and how the various factors you're talking about come into it.
How to think about transmission media Transmission media can be anything from an electrical conductor to vacuum. increasing the utilization of a transmission medium without significantly increasing the band- width requirements forms the basis for the use of TDM in telecommunications.
Analog vs. Digital Transmission There are three predominant methods of encoding a transmission analog and digital transmission deals with the hardware's ability to recover the transmitted signal.
Analog modulation, which is continuously variable by always be the most cost-effective system to specify. However, today's demand for high.
Explanation: Digital data communication was only restricted to communication between computers. Since analog signals can now be easily converted into digital signals using analog to digital converter, digital transmission can now transmit voice, video and other analog signals in digital form.
Design of a Digital Communication System ited by various factors, including the range over which the medium and the transmission circuitry behaves linearly. In many other cases, This is, of course, a completely analog transmission sys-tem, which is schematically displayed in Figure One key difference between analog and digital transmission involves the bandwidth, or transmission capacity required for both schemes.
Analog signals require much less bandwidth, only about MHz with a Mb/s data rate. for the average NTSC video signal.Download

Advantages of a Premise Based PBX
The age of Voice over IP (VoIP) has become the new standard in telecom. The increasing advantages of connecting your phone system, such as the New Rock pbx system, to the internet is obvious, but that doesn't mean you're required to give up control of the system to a third-party.
VoIP comes in many forms, With SIP trunking, the IP Office can send your calls over the internet. This provides much of the savings you would recognize going to a 100% VoIP phones solution, without moving all of your equipment to an offsite data center while maintaining control and uptime.
CARRIER VERSATILITY. Why would you need different types of dial tone service for your business? You may have services that require landline phone service such as lifeline systems, HVAC, security, etc. However, for a business that requires a High Availability solution, carrier redundancy is an important consideration. Similar to ISP failover, an HA environment should consider diversity in dial tone (SIP, PRI, POTS) to ensure your calls are always flowing. The IP Office can service multiple carriers at once, offering failover in the event of carrier downtime.
COST OF OWNERSHIP. By purchasing the equipment and licensing, your business can drastically reduce its telecommunications expense over time. This will depend on the businesses plan to keep the phone system in place, however, it is a great option for businesses that can properly forecast their technology needs over the life of the IP Office.
TOTAL CONTROL. Control of the phone system equipment is ideal for larger organizations that already have the infrastructure setup to host their own platform. Controlling simple tasks like re-routing phone numbers or adding extensions is something any organization can benefit from. However, you're not alone. Third party service agreements are available that will only increase uptime.
REDUCED FEATURE COSTS. Complexity equals cost, but it doesn't need to be excessive. If your feature requirements include technologies like Call Recording, Contact Center, Advanced or Custom Reporting, the IP Office offers this in a cost effective manner instead of expensive recurring user fees that can add up quickly on larger systems.

Gubagoo’s Website Platform Now Optimized for Mobile
WEST PALM BEACH, Fla. — Gubagoo’s behavioral analytics-based chat and website engagement platform for dealer websites is now fully optimized for mobile, the company announced this week.
The new capability is designed to allow dealerships to track and then relevantly target — through chat, personalized offers and inventory display — every single visitor that hits their website via a smartphone or tablet.
With an estimated 30% to 40% of dealer site traffic now coming through mobile devices, Gubagoo is serving up the chats, offers and inventory to on-the-go mobile shoppers. The solution also keeps shoppers on the dealership’s mobile site rather than forcing consumer onto another page and breaking continuity, officials noted.
Free to current clients of the company, Gubagoo Mobile works on any native smartphone or tablet device, requires no app downloads and is able to automatically detect the presence of a mobile browser. It then instantly sets the mobile engine in motion.
“Very soon, mobile will overtake the desktop as the way most people access dealer sites,” said Brad Title, CEO of Gubagoo. “And if a dealer’s vendors don’t enable smarter chat and more relevant site communications on mobile, they’re throwing 30% to 40% of their traffic away.”
