For another side-project, I have bought three Xbee Pro 900HP. Here is a description of these modules, according to the manufacturer:
XBee-PRO 900HP embedded modules provide best-in-class range wireless connectivity to devices. They take advantage of the DigiMesh® networking protocol, featuring dense network operation and support for sleeping routers, and are also available in a proprietary point-to-multipoint configuration. Supporting RF line-of-sight ranges up to 28 miles (with high-gain antennas), and data rates of up to 200 Kbps, these modules are ideal for extended-range applications requiring increased data throughput.
With such a long range, the number of possible applications is immense. On their blog, Digi wrote:
Companies have utilized this module to develop some amazing products, like intelligent wireless street lighting systems, mission-critical radiation detection systems at power plants, and even beacon systems used in firefighting suits.
Although, a large amount of Xbee models are based on the ZigBee protocol, the 900HP uses its own proprietary protocol. This series of posts has the objective to reverse this protocol but also, to provide general guidelines on how to reverse any unknown RF stack.
It must be noted that this analysis has been possible because the price of SDR has dramatically decreased in recent years. As proof, the RTL2832U (~20 AUD) has been used for most of this work.
Reading the documentation
The first step to reverse the physical layer is to read the documentation that has been released by the manufacturer. It may give us some insight on the underlying technologies. If not available, extracts from the FCC Test Report may help. In our case, the User Manual is freely available and contains more than we need to start.
First stop is the Key Features of the Xbee section. FHSS (Frequency Hopping Spread Spectrum) is mentioned in the Advanced Networking & Security subsection. The focus of this first post will be on that feature. Let’s continue with the manual. A bit further down, the documentation for the read-only command AF states:
This command returns a bitfield. Each bit corresponds to a physical channel. Channels are spaced 400 kHz apart:
Bit 0 – 902.400 MHz
Bit 1 – 902.800 MHz
Bit 63 – 927.600 MHz
That’s 64 channels. Depending on which version you have, only a subset of these is active. For the Australian version (the one I am using):
Australia: 0x00FFFFFFFE00000000 (channels 33 – 63)
A bit further down:
A minimum of 25 channels must be made available for the module to communicate on. The module will choose the 25 lowest enabled frequencies as its active channels if more than 25 are enabled.
So only the first 25 channels will be used. For us, that is channels 33 to 57, from 915.6MHz to 925.2MHz. To be able to capture these 25 channels we would need about 10MHz of bandwidth. Unfortunately, the RTL2832U is limited to 2.56MS/s (without sample loss). With such bandwidth, we should be able to capture around 4 channels at a time.
Lab set up
For the sniffing, I’ve used a customised RTL-SDR (RTL 2382U/E4000) (left).
The XBee operates in two modes: either transparent (every character sent to the serial port is forwarded) or API (the serial port expect a structured binary flow that encapsulates the data). Using the transparent mode is the easiest. Here is a Python script that opens ttyUSB0 and send “A”s:
import time import serial ser = serial.Serial('/dev/ttyUSB0', 57600, timeout=1) while True: ser.write("A" * 1024) print "." time.sleep(0.1)
At this stage, we are not sure how much is effectively sent (potential buffering or waiting for acknowledgement before data transmission). By default, the XBee is configured to broadcast its input (destination address=0xFFFF). When run, the transmission LED of the breakout board is almost always on, that is a good sign that some packets might be flowing.
It is time to test if our assumptions drawn from the user’s manual hold. Although, a considerable amount of tools exist to interact with the RTL-SDR, GNURadio is generally the preferred method, because of its flexibility. Here is the first program, plotting the FFT of our full bandwidth:
The important part of this diagram is the settings of the modules. Mainly, the bandwidth (2.048MS/s) and the capture frequency (916.2MHz). We are hoping to capture between channel 34 and 35. Here is the output:
The FFT is plotted in blue, the peak values are in green. The first four channels are clearly visible with the peak values between -20 and -10 dB. As predicted, the channels are separated by 400kHz. The first channel is centered around 915.6MHz, the second around 916MHZ, the third around 916.4MHz and the forth around 916.8MHz. Note that we can even see half of the fifth channel on the right. At the time of capture, you can see that channel 35 (the fourth one) was being used.
We are now going to try to isolate one channel from the full bandwidth. To do so, we use the Xlating filter. For an introduction on that module and how to use it, I recommend watching GNURadio Tutorial 3 or reading this tutorial.
From the first FFT, it seems that one channel is about 200kHz large. The tap of the Xlating filter is a low-pass filter with a cutoff frequency of 100kHz and a transition bandwidth of 50kHz. These are just defaults, we will be using GUI sliders to modify them while the code is running:
Here are the peak values observed:
In that sample, our centre frequency was 916MHz, which should be the centre of channel 34. However, it is quite clear that the signal is shifted on the left. To correct this, we will use an offset of -30kHz. The same correction will be applied to the other channels.
Here is our shifted and trimmed channel (cutoff = 100kHz, transition bw = 50kHz):
Back to the time domain, we may use an oscilloscope to visualise the signal. In its current form, the signal is a complex value (I/Q). We will plot its magnitude:
At that stage, we can note that this channel is being used for about 16ms. We will dig deeper into the signal itself in a subsequent post. For now, let’s focus on the relationship between the channels.
Reversing the FHSS pattern
Now that we know how to isolate one channel, we can repeat the filtering to isolate the neighbours channels:
Channel 33 is blue, 34 green, 35 red and 36 purple. We can see that each frequency is utilised in a specific order. This exact same pattern is being repeated over time.
The order in which each channel is being used is called the hopping pattern. In our case, there is obviously some space between channel 34 (green) and 36 (purple). We can assume that some channels (two to be precise) are being used during that time. Unfortunately, because of our capture limit, we cannot see these. To solve that issue, we simply need to repeat this operation with different capture frequencies that overlap. Once done, it is about solving the puzzle of frequencies’ order. Below is the reconstructed order:
This is the end of the first part. In the next post, we will analyse one packet in particular and try to reconstruct its content.

Team instant messaging apps vs. work hub
Instant messaging apps or chat solutions replicate the casual flow of ideas that can happen in an office context while connecting team members across countries and time zones for more effective online collaboration.
However, research from Qatalog and Cornell University shows that instant messaging apps, along with the other tools in your arsenal, actually contribute to disorganization. 54% of people say that apps can make it harder to find information, and cycling through different messaging, collaboration, and productivity tools wastes almost an hour per day.
Our reliance on messaging is a double-edged sword. Hybrid teams need an avenue for communication, but a case could be made for instant messaging apps not being the full-proof solution for modern work.
They do have their pros, though. Team messaging apps allow teams to:
- Separate team conversations into channels for different people and projects
- Start voice or video calls
- Share files and documents to collaborate on them
- Communicate with your team across time zones and locations
Here are a number of instant messaging apps that we love:
The 5 best instant messaging apps for hybrid teams
Slack has, without a doubt, defined the team chat space. It was developed for the user, and packs in delight through audio calls and custom emoji capabilities. For all that Slack has done for the instant messaging space, it makes sense that it’s the frontrunner for everyone’s favorite. However, there is a lot to be said about the impact Slack has had on remote office communication — which we’ll get into in a little bit.
2. Microsoft Teams
Microsoft Teams is part of the Office 365 offering and creates a chat-based workspace. Teams offers instant messaging, video, and audio calls. Teams, as well as the Office 365 offering, is optimized for larger teams who can have a dedicated IT staff to assist with the rollout.
3. Google Chat
Google offers a lot of work software, including a free instant messaging app. Google Chat, rebranded from Google Hangouts Chat, breaks conversations down into chat rooms, similar to Slack’s channels. The ease of Google Chat comes with how easily it integrates with the rest of the Google suite.
Discord is similar to Slack or Microsoft Teams, but its interface was developed to be more gamer-friendly than business-friendly. Huge pros: most of the features that you’d need are included in the free plan, and its audio features are an interesting benefit for async communication. Cons: its lack of threads could make file sharing a little chaotic.
HipChat features the classic instant-work-messenger capabilities including 1-on-1 instant messaging, group chat rooms, and file sharing. They also include screen sharing and video conferencing.
What makes a great work messaging app?
Workplace communication is vital to creating a healthy, happy, cross-functional team. Especially in the era of modern work, communication has to be a frictionless experience across all sorts of barriers. Your instant messaging app shouldn’t be one.
A great instant messaging solution for hybrid teams:
- Enables organized communication and collaboration. Team instant messaging apps should enable communication, that’s a given. The important part here is organized communication and collaboration. It’s one thing to shout into a void of singular updates that aren’t attached to the context of work, but collaborating requires both organization and context.
- Offers a search feature. With instant messaging comes the ability to chat about things unrelated to work. So finding that design file you sent a co-worker on Friday afternoon might not be the easiest thing to scroll for on Wednesday morning. Being able to search for files and messages based on keywords, channels, or who the message was sent to is a necessity for work IMing.
- Provides a user-friendly interface that the whole team actively uses. According to our research with Cornell University, 58% of people report that not all departments use the same online apps. Obviously, this leads to silos and creates organizational roadblocks. Instant messaging should be not only accessible to everyone in your company but utilized by every team.
The three main challenges of team messaging apps
Of course, the things that should make a team chat app great are expectations, not reality, and there are a lot of things that can become overwhelming when you’re expecting an instant response from your coworkers throughout their 9-5 workday.
1. Information overload
With the endless number of conversations taking place on your team messaging app, the tool can start to look increasingly like the mythical Hydra — sprouting new heads (or threads) the more you try to get it under control.
As an individual team member, it becomes harder to know which information is relevant to you, so you might end up missing a crucial project update.
Or, if there are too many messages, team members might feel discouraged and decide not to read them at all. Once those little red notifications take over, it can be hard to get them to disappear.
2. Short information shelf-life
The ease and speed of team messaging might be a benefit, but it also has the side effect of devaluing the information that’s shared.
Team members get used to messages being swept away in the thread, so information distributed in this way might lose significance. Fine for a quick emoji — less ideal for important weekly team updates.
3. Diversity of formats
In team messaging apps, information is shared in diverse formats — messages, voice calls, document links. When everyone has their own way of writing updates, setting meeting agendas, or naming links, it’s hard to navigate the complexity.
Details of a project can be spread across multiple messages and/or calls, making it difficult to monitor progress.
A work hub is a vital addition to your team’s instant chat
Instant messaging isn’t sustainable as the sole vehicle for workplace communication. Information overload can be a huge added burden to employees trying to shuffle through the noise of the day-to-day.
Adopting a work hub in addition to your instant messaging tool helps adds context to the information constantly being sent back and forth. It also gives you a place to connect the work being done with your instant communication, resulting in cross-team collaboration you didn’t have to dedicate time to sync on. Plus, it makes all your work inextricably linked.
Adopt longer, context-driven async updates with a work hub
A work hub breaks down silos by cascading updates and comms automatically to the right channels, for a feedback loop that doesn’t require a pingback. By integrating a work hub with your instant messaging tool, you can send structured updates (complete with context, goals, files, and the teams involved) to the right messaging app channel.
Threads in Qatalog allow everyone to comment on projects in an organized way. You can follow threads and stay aligned with all your critical conversations. Plus, with our smart feed, you get a personalized dashboard of important updates across posts, threads, projects, and goals.
The async messages of a work hub keep everyone in the loop of things without intrusive, focus-breaking noise and red badges — whether it’s a project update, team weekly, or personal news shared with the team.
And when adding a work hub to your existing tool stack, it takes the reliance on instant messaging down a notch. Now you don’t have to panic about finding that one file that was sent in the chat before you started talking about the movie marathon you had this week.
Search for information, easier
On Slack and Teams, you can have one channel per topic, but when there are tons of messages on each channel, it’s hard to retrieve the right one — especially if you don’t have the right keyword or when search doesn’t deliver as quickly.
Qatalog doesn’t replace your synchronous messaging app but rather complements it. When you integrate your messaging app with Qatalog, you make every single message retrievable, through a powerful, custom-built, full-text search. You add context to the messages being sent back and forth. And you cut through the noise.
Keep work together with a Slack integration
Sometimes in-depth project discussions end up happening in Slack, when they really should be visible to everyone. Keep track of decisions and feedback by easily adding a thread from Slack directly into Qatalog. Your content stays together and your team stays updated and informed.
Team instant messaging apps vs. work hub
There are remote teams that have ditched instant messaging apps entirely, citing addictive qualities, disorganization, and the inability to conduct in-depth conversations. Some have even argued (myself included) that reliance on instant messaging detracts from a true async-friendly working model. Because if your team has to be ready to respond to a message at all time, who is getting the deep work done?
Some teams still rely on instant messaging as their only form of direct communication. By now, you know that we think this is a mistake and it’s keeping your company from advancing to modern work. Instant messaging might still feel like the future, but in reality, it sits with the rest of your legacy tools keeping you in the “old way of working.”
A work hub isn’t a replacement for instant messaging, it’s an important addition that gives you context and enables you to connect with your team. The new way of working is communicative and people first, so stop being distracted by the endless notifications.

While the popularity of connected ink jet printers is declining, connected surveillance cameras have been going up for several years. These products connect to your pc via Wi-Fi and are being among the most popular linked devices. But the biggest concern with these devices is usually their low self-esteem. While most IoT devices concentrate on solving a particular problem, other folks are built to solve a broader issue. The security problems WebAccess review associated with these devices are the biggest concern with IoT, so these devices are definitely not for everyone.
Many of the most popular IoT devices will be voice-enabled products. The Amazon Indicate Plus can be an example of this. The device may play music, interact to voice directions, and even control external equipment, such as lamps. Other well-known IoT gadgets include the Amazon Dash button and the Yahoo Home. The Amazon Dash button contains a camera and can scan bar codes to order items. Additionally, it may be connected to a Wi fi signal to keep burglars out.
The Amazon Echo Plus is a popular IoT product that can hook up to your various other gadgets. It might play music, get suggestions, and even carry out your commands. One other popular IoT device is a Amazon Kuri. It can reply to your tone and interact to your requests, and it has a sensor contact, HD camera, and innovating colour. An Amazon Splash button may scan bar codes to notification you of any visitors. You can also speak to it approach them.


The Wireless Research Centre has several fields of interest when it comes to wireless communication. We have a wide range of topics that we are focusing on and we are eager to hear from others who find a mutual interest in these areas of interest.
The Centre conducts research on the following topics:
MIMO and Diversity Techniques
MIMO stands for multiple in, multiple out. The coverage of this research focuses finding ways and means on how to improve the quality of wireless links through the various methods and techniques of using two or more antennas in order for it to be more stable and reliable.
Software Defined Radio
A software defined radio or SDR is a means used to implement certain components through a computer software instead of it being traditionally implemented through hardware such as an amplifier.
This research covers cognitive radio or a network technology that is capable of detecting channels within a wireless spectrum which are used and move on to another vacant one thus allowing more communications to run at one time.
OFDM and High Data Rate Modulations
OFDM stands for Orthogonal Frequency-Division Multiplexing. It is a scheme used to encode digital data on varying frequencies. This multi-carrier scheme is used by companies in providing DSL internet and wireless networks, radio and television broadcasts, and even mobile service providers have dived into this scheme.
The Centre’s aim for OFDM is finding means of improving its quality and performance for more stability in the connection.
Sensor Networking and the Internet of Things
A sensor network is a wireless network that is composed of wireless sensors or nodes. The network is used as a means of collecting data, which monitor the physical and environmental conditions of a remote location and subsequently pass the collected data to a main location.
Internet of things pertains to physical things and devices that are made out of electronics, sensors, or has network connectivity that allows it to gather and exchange data.
This area of research focuses on finding solutions for a more effective and efficient way of collecting data regarding physical and environmental conditions.
Mission Critical Communications and Resilient Networks
This area of interest focuses more on researching and understanding the different kinds of weaknesses that the wireless communication technologies are exposed to and finding solutions for its recovery in cases of exposures to risks.


At Ford’s advanced manufacturing center, robot Javier can operate 3D printers by themselves -he is never late, the action is very accurate, and he works most of the day every day -just a short break to charge. Robot Javier is an automatic mobile robot developed and manufactured by KUKA. It replaces a fixed device to operate 3D Carbon printer. Ford 1.JPEG Ford uses mobile robots to operate 3D printers. (Picture from Ford) \”This new process is expected to change our way we use robots in manufacturing facilities.\” Jason Ryska, director of global manufacturing technology development, said, \”It not only enables Ford to expand its 3D printing business, but also optimize other manufacturing processes ——It can help to make industrial and commercial simplifying equipment and achieve flexible assembly. \”Ford said that the operation accuracy of the robot Javier is extremely high, and the feedback information can be significantly reduced. In addition to operating a 3D printer, this method can also be applied to a large number of robots that Ford already on the job to improve efficiency and reduce costs. At present, Ford has applied for a number of patents for the overall workflow of the robot, communication structure, and precise positioning. It is worth noting that the robot does not even need to use the camera visual system to \”see things\”. Generally, different equipment from different suppliers cannot interact due to inconsistent communication interfaces. Ford has developed an application interface program that allows different devices to \”speak the same language\” and continuously send feedback to each other. For example, the 3D Carbon printer told KUKA mobile robot to print the completion time, and then the robot let the printer know that the robot has arrived and prepares to receive. This innovative communication method makes the entire process possible. At present, the robot Javier is still able to operate its 3D printer at night after the Ford employee is off work. This not only increases production, but also reduces the cost of custom 3D printing products. Ford has used a printer to create small -scale customized parts, such as a brake pipeline bracket equipped with Mustang Shelby \u0026#174; GT500 Performance Kit. Ford 2.JPEG mobile robot can operate 3D printer to print car parts by themselves. (Picture from Ford) Although the entire operation process is fully automated, Ford’s operators still need to upload 3D design to printers, maintain machines, and develop new methods to use the technology.


The Scott County Sheriff’s Office will send a test phone call to Scott County residents on Monday, Jan. 14, by using the CodeRED Emergency Notification System. The purpose of this test call is meant to announce and promote the CodeRED Mass Notification system and the Weather Warning system, an automated severe weather alerting service.
The calls will start at approximately 11 a.m. and will continue until the entire database has been attempted. It is expected that all calls will be completed by 3 p.m.
The message will direct recipients to the Scott County website to opt into the system and select the types of warnings they are interested in receiving. Citizens must add their information to receive the severe weather warning calls; this data will also populate the CodeRED database.
Chris Weldon, the Scott County emergency management director, recommends that everyone should consider opting in to the CodeRED Weather Warning system. He also suggests that “all individuals and businesses should take the time to visit our website and add contact information to include cellular phones and other non-traditional phones as well as email and text addresses (for use by the CodeRED system). If your contact information is not in the database you will not receive a call.” In particular businesses should register, as well as individuals who have unlisted phone numbers, who have changed their phone number recently and those who use a cellular phone exclusively or have VoIP phones (such as Vonage) as their primary numbers.
Weldon urges citizens to log onto the Scott County website at www.co.scott.mn.us and follow the CodeRED link.
The data collected will be used only for emergency notification purposes. Required information includes a street address (physical address, no P.O. boxes) for location purposes and a primary phone number. Additional phone numbers, email and text addresses may also be entered.
Those without Internet access may call (952) 496-8381 Monday through Friday from 9 a.m. to 4 p.m.
Questions should be directed to the Emergency Management Office at (952) 496-8381; more information about CodeRED and Emergency Communications Network (ECN) can be obtained at www.ecnetwork.com.


Sonos is the wireless home sound system that fills as many rooms as you want with great-sounding music, movies and TV. Stream via Wi-Fi. Play whatever you’re craving. And amp up every moment with intense, pulse-pounding sound.
Simply download the Sonos app and follow the instructions. Put your speaker wherever you want. Plug it in. Tap the app. It connects to your Wi-Fi and then you’re ready to play. For everyone in the house and all their devices – smartphones, tablets and computers. Now you’re ready to set up your Sonos and start to stream music. When friends come over they can download the app and play. The Sonos app helps you quickly search through all your services to track down your favourite music, send it to different rooms and adjust the volume or other settings. You don’t even have to be in the same room. And, if your friends have the Sonos app, they can do the same.
Can I connect the SYMFONISK speaker to my Sonos system at home?
It matters when the phone rings or the person with the music has to leave. With SYMFONISK, the songs stream from your Wi-Fi network (not your phone), so there are none of the dropouts, delays or interruptions that are associated with Bluetooth
Do I need to have my speaker connected via cable? (Why do I need an Ethernet port on a speaker?)
The Ethernet ports let you connect Sonos directly to your Internet router. If your Wi-Fi network isn't reliable or doesn't reach all the areas where you want to use Sonos, you can automatically create a dedicated Sonos wireless network by connecting a Sonos product to your router with an Ethernet cable.
When I leave my house will the music stop playing automatically?
On a good network, approximately 30 speakers will usually work fine. Your sound is not limited to one room. The real power of a Sonos system kicks in when you add more speakers. Now you’re controlling different music in different rooms. Or grouping all your speakers together to every room at once. Since everything works together wirelessly, it’s easy to fill your whole home with music, room by room.
How many phones can I connect to a speaker simultaneously?
Only if the music that's playing is stored on the device that you turn off. Smartphones, tablets and computers can all control Sonos using the app. These devices can also store music for Sonos to play. The music will stop if you turn off a device that stores the music that Sonos is playing. However, if you control Sonos from your phone and play music from the Internet or your computer, the music won't stop when you turn off your phone. It's just like putting away your TV remote while the TV is on.
Can I use Sonos speaker without an Internet connection or a router?
There is no built-in voice functionality but you can control the Sonos system with Amazon Alexa (when in use with one of Amazon devices like Echo or Dot) and Google Home (using its devices). And, if Sonos enables integration of other services, they will be possible to use.
Will the app that controls the sound also steer the lights?


While archiving the documents used to plan and implement Nouncer, I came across the original document written a little over two years ago (with some minor more recent revisions). It details my service plan, ideas for patents and trademarks, the original name for the service ‘JabAbout’, and a long list of features. It also includes the initial thoughts on the architecture and technical challenges. If you love microblogging or am working on a startup, this is a good read. One funny thing to note, it was written around the time Twitter was launched and before I knew about it – hence Twitter isn’t even mentioned as an example.
The document one line explanation of the service is: “Creating an internet service to enable companies and individuals to send messages in real-time to large audiences of interested subscribers via Instant Messaging and other technologies, and providing subscribers with tools to find and filter content to fit their needs and ability to handle the content load.”

How to Boost Mobile Internet Speed: Is the Internet speed slow in your phone? There can be many reasons for this. Then if you are also bothered by slow internet speed then you should change the phone settings a little.
Slow internet speed is one of the most annoying situations. First the user’s work stops. On the other hand, one also feels cheated. Because high-speed data costs a significant amount of money. Do you also think that the internet speed in your smartphone is slow?
Troubled by slow internet speed?
You can fix it very easily. For this you have to keep some things in mind. Smartphone users keep looking for tips to increase internet speed. At the same time, it is also thought why not switch to Wi-Fi, which will provide better internet connectivity. But before taking such a step you should take care of some things in the phone. Let’s know some important things related to slow internet. How to Boost Mobile Internet Speed
Why is your Phone Slow?
Many times we feel that our smartphone or laptop is working slowly. But this does not happen, the reason is the Internet somewhere. There can be many reasons for slow speed. For example, you have several apps open, which should be running in the background. This also affects the speed of the phone a lot. How to Boost Mobile Internet Speed
At the same time, another reason could be a bad connection. If you live in an area with fewer cell towers, but more users, you will get a poor connection. The reason for this is the load on cell towers, which can be reduced only by increasing the number of towers.
Apart from this, your phone settings can also cause slow internet. Many times the settings in the smartphone get messed up, due to which the internet speed is affected. However, you can increase the internet speed by making some changes in the phone settings. How to Boost Mobile Internet Speed
How to Boost Mobile Internet Speed
For this you have to keep some things in mind. First of all, you should try to clear the cache of the phone. Whenever the cache memory is full, the phone automatically slows down. That’s why smartphone users should clear the cache every few days. By doing this you can increase the internet speed of your mobile. How to Boost Mobile Internet Speed
Close all Apps
If you have opened more apps than you need, you should close them. As these apps work in the background, they continue to use the internet. Due to which the internet speed becomes slow.
If you want, you can also turn off background data for apps. However, this won’t get notifications from apps like WhatsApp. But you can also improve internet speed by closing recent tabs. How to Boost Mobile Internet Speed
You can also increase internet speed by resetting smartphone settings. For this you have to go to phone settings. In mobile network you will get network option. Here you have to turn off the automatic setting. Finally, you have to setup the network yourself. On the other hand, you have to select the best option in the preferred network in the mobile data/network option. How to Boost Mobile Internet Speed
Turn off Auto Updates
If you have turned on auto-update on the phone, it should be turned off by going to settings. Users don’t know as apps are stuck on auto update and internet speed is slow. You should turn it off.
Restart the phone
You can also restart the smartphone. This refreshes the phone and you might start getting better speed. If even after these settings you are not getting network or good connectivity, then it is clear that your telecom operator is not able to provide good service in your area. In such a situation, you can switch to another telecom operator or even consider a Wi-Fi network.

Steve Barclay MP encourages mobile users to take a stand against signal ‘not-spots’
- Credit: Archant
Mobile phone signal gaps across the UK need closing to ensure the whole country has reliable communication, MP Steve Barclay has urged.
People in the Fens and East Cambridgeshire are being encouraged to speak up in support of a new campaign which aims to put a stop to the ‘signal gap’ between urban and rural parts of the UK.
Mr Barclay is joining the Countryside Alliance in asking mobile users to become mobile phone ‘signal detectives’ by getting involved in a new campaign which highlights the issues faced by residents in rural areas who suffer from poor signal.
The campaign hopes to generate a review into connectivity issues across the UK.
The Countryside Alliance is offering mobile users a free app to test phone signal strength and internet download speed in their area. The results will then be used to create an interactive virtual map identifying key connectivity ‘not-spots’ across the country.
You may also want to watch:
Mr Barclay said: “We need to send a clear message to mobile phone companies that poor quality signal is an issue that has a major impact on people and businesses in rural constituencies like my own.”
“It is unfair for mobile companies to be promoting the expansion of next generation 4G service whilst there are many around the country who struggle to receive a basic signal”.

- 2 Drug dealer racially abused police officer
- 3 Person cut out of car after two-vehicle crash
- 4 Woman has heart attack and dies in ambulance waiting for a hospital bed
- 5 Crews tackle huge Fens blaze
- 6 Piled wall will resolve major King's Dyke crossing obstacle
- 7 Photographer, Eleanor, wins highly regarded award
- 8 'I think I hurt him bad mum' says Murder on the Doorstep killer
- 9 Three charged after £2m Hotpoint arson attack
- 10 Have your say on new political map for Fenland council
“This is not only a social issue but also an economic one. The current ‘not-spot’ situation costs the British economy £1.3 Billion every year. I encourage mobile phone users in Fenland to make use of the free signal strength app on offer as it is a key tool to identifying and eliminating connectivity problems”.
It is estimated that signal black spots currently affect 12.8% of the population, most of them located in rural areas. The figure is likely to be even higher for the Fens, Mr Barclay said.

I know from talking to customers and colleagues that mobile devices cause all sorts of security headaches. It’s all very well having your desktops and laptops locked down and secure, but no company can ignore Blackberries and other mobile devices. And keeping laptops of remote workers properly updated and set up with security software is notoriously difficult.
This article in Network World has some useful perspectives, but I think it misses the most important point. If you put your email security and data loss prevention technology onto the email server, not the mobile device, then you’re protected for any messages that go through the server – whether users have sent them from desktops, laptops, PDAs, or whatever. Simple but effective.

The controls are organized in a traditional three-tier layout.
Tier 1 (hardware access): Verilog code targeted at the XC2S150 FPGA that lies at the center of the custom hardware. Includes a direct digital frequency synthesizer (DDS), a low-latency vector PI feedback control loop, four-channel vector waveform capture, and support for on-board housekeeping circuitry.
Tier 2 (network presentation): C code targeted at a 32-bit microcontroller, which has a direct connection to both the FPGA and to Ethernet. This layer is itself divided into a HAL (hardware abstraction layer) to mediate access to the FPGA registers, a driver to organize all the application-specific computations (including a waveform curve fit that determines cavity detuning), and a toy network access protocol.
Tier 3 (operator interface): A Tcl program that exchanges data with tier 2, and gives the operator a virtual control panel for the hardware.
In the production SNS installation, the toy network access protocol and tier 3 are replaced with EPICS. The code given here is dramatically smaller and simpler than EPICS, yet gives enough functionality to demonstrate proper operation of an RF cavity.
The SNS facility now uses three generations of LLRF control hardware. This package supports all of them, although support for the first ("MEBT") system is yet untested. It may also be adaptable to future LLRF projects at LBNL, other National Labs, and worldwide.

The love and affection between pets and owners goes creates a bond that is second, for most, only to their human relatives and friends. So when a beloved pet goes missing the distress can be a huge upheaval to the owner. Recently listening to a radio show on lost cats you could hear the emotion in so many of the contributors. I imagine should it have been a TV show, instead of a radio program that the images of the owners would have been distressing. They discussed what was the best plan of action should you discover that you have a lost cat. The problem with cats is they say that they say that actually many have second or even third owners who they also visit less frequently than the number one owner. In addition cats have a tendency to curl up in people sheds and garages and then end up being locked in by mistake. Should an investigative mission not come up trumps then poster campaigns are often successful followed by professional search teams, a few which now actually use sniffer dogs. Often the result is positive and the lost cat is found but occasionally cats are just never found. Not the most joyous radio program I have listened to but all the same informative and eye opening.
Digital Audio Broadcasting, or DAB, is a digital technology that is designed to broadcast radio stations to a wide audience.
Initial development of DAB technology began in the early 1980s in Germany and first DAB transmissions were made across the country in 1988. Key choices concerning the specifics of the technology to be used were made in 1990 and the complete protocol was finalized in 1993.
The United Kingdom was the first country to adopt DAB as a widespread radio broadcasting system. The first commercial DAB radio receivers went on sale during 1999 and by 2001 there were more than 50 DAB stations being broadcast across London. These first stations were either run by the BBC (British Broadcasting Corporation) or individual commercial ventures.
In 2006, approximately 500 million people worldwide were within coverage of DAB radio broadcasts but sales of DAB receivers were still limited to a handful of European countries. Around 1000 DAB radio stations were in operation around the world at this time.
One of the main objectives of developing DAB radio was to improve the overall sound quality of transmissions by achieving higher fidelity and more resistance to noise and interference.
On many of the early DAB systems however, a better quality of sound can be achieved via the established FM (Frequency Modulation) radio stations due to the relative inefficiency of the audio codec used for DAB broadcasting.
Despite this failure to improve sound quality there are many other benefits inherent to the DBAB system. DAB radio stations are more bandwidth efficient than their analogue counterparts, so more stations can be made available and broadcasting costs are lower.
DAB radio transmitters also have the capability to automatically tune to a particular station chosen from a list, as well as receiving textual information about the broadcast, such as the title of the current song or traffic information for the station.
A newer version of DAB, termed DAB+, was made available in 2006 with the adoption of a new audio codec. This upgrade has the primary goal of achieving greater sound quality for DAB radio transmissions.

The positive note is that the young apprentices don't fear technology. They have grown up with mobile phones, text messaging, email and social networking. They are willing to embrace the use of these technologies in the workplace. There is hope!
M2M (machine to machine) communications is being used extensively by the gas distribution company I met last night. They have a broad range of different remote M2M sensors on their pipelines that wirelessly send data back to a central server. Although these M2M devices are widely deployed, the challenge is still around how best to use the data from these remote sensors. There is still a lot of work to be done that will turn this data into actionable intelligence.
It takes only one minute of discussion with a utility company in Australia to understand how necessary it is to have mobile applications that can run offline and online. It only takes a short drive away from a main road to lose mobile phone connectivity in the outback. Satellite phones and specialized radios are normal equipment for these IT organizations. The IT assumption is that there will always be limited connectivity. All mission critical mobile applications must work with this assumption.
Last week in Europe, I heard the same kind of requirements for offline and online mobile applications. Several of the companies I was meeting with had a significant presence in Africa and South America. Mobile application connectivity cannot be assumed.
I think back to a discussion I had with a member of the Sybase team in the UK earlier this year. He shared that there were three locations between his office and his home where he could not get connectivity on his mobile phone. I think we all need to remember these issues and not assume global connectivity when we are thinking through mission critical mobile application designs and architectures.
What does a mobile application that can run offline or online look like? It will have the capability to store data in the mobile application on the mobile device that can be synchronized, at a later time when there is connectivity, to a back office database. This kind of application requires a comprehensive mobile middleware solution that includes synchronization technology, on device data storage and backend integration capabilities.

You’ve probably heard about the smart home network hype and wondering what it can do for your home. Maybe, you’re considering turning your home into a tech-savvy nest but you have no idea where to begin- then this is the right guide for you.
Below are the foundations of creating a smart home network so you can navigate through smart terminology, basic smart home building, and numerous setups. If this is right up your alley, continue reading.
Understanding the Smart Home
Picture yourself waking up to the aroma of fresh coffee, lights switching off whenever someone steps out of a room, or your home at the perfect temperature when you get home. “Smart home” means that various gadgets, appliances, and systems around the home are interconnected.
What’s more, all of them seamlessly communicate with each other and you. On the other hand, a “smart network” offers you control over the operation, programming and automating of the connected devices depending on your needs.
Understanding Home Automation
This term is used to refer to items around your home that are programmable to work automatically, without requiring your input. Some of these include simple gadgets like auto light dimmers and fan timers.
Recent updates like the best home security IP cameras and laundry appliances offer more home automation capabilities. While the main aim is for practical use, entertainment, don’t forget that you have many reasons to think about home security too. In fact, the recent home tech boom has virtually increased the possibilities to near endless. Other appliances that you can include in your smart home network and control via a smartphone include:
· Kitchen appliances
· Bulbs, doors, and switches
· Video, audio appliances
How Devices Communicate
At the heart of building your own smart home ecosystem is ensuring that all devices use the same communication protocol. In other words, all your devices need to speak the same language. Common home automation communication protocols are:
The commonest communication protocol used by most wireless devices and requires minimal power to operate. It’s best used in a single room due to its limited range.
One of the most popular protocols where you use your wireless router to connect to devices through mobile apps. However, if you have many devices connected to a router – tablets, phones, laptop and TV – you may suffer bandwidth issues.
Offers you one-way communication between remote controls and devices like your TV, home theater system or air-conditioner.
· Z-wave, Zigbee
Alternatives to Bluetooth and Wi-Fi with longer range and less power consumption. However, these protocols require a central hub for connecting to the Internet.
Networking Devices Required
Understanding home networking is most often difficult because most of the happenings are not visible. In addition, it’s harder to understand how Wi-Fi works when you cannot physically see what happens. Which is why you should start by looking at the part of your network you can see – networking devices.
Home networking devices include physical boxes and cables required for setting up and running your network. The collective name for these physical devices is hardware.
The networking hardware is available in various sizes, shapes, and varying functionalities. Here are the most common network devices you’ll need to create a smart home network:
This device acts as a bridge that connects two separate networks. For example, in your home, the router is the gateway that offers a connection between your broadband provider’s network and your own personal network.
· Wireless Access Point (WAP)
The device used for creating a Wi-Fi network from a wired network.
· Network Switch
This is used for connecting multiple wired devices to your network. However, you are less likely to find it in a home due to the popularity of wireless Internet. Nevertheless, it’s still used in complex smart home network setups and business environments.
· Ethernet Cables
These are the staple for wired networks and are used for connecting your router to your Internet connection.
This device is the heart of your home’s network that passes traffic back and forth between your devices and the Internet.
If you live in a big house or have Wi-Fi blackouts, an extender can be used to expand the range covered by your wireless network.
· Firewall Device
This is a piece of hardware that’s plugged into the router and blocks malicious traffic like malware from accessing your home network.
Putting Together Your Smart Home Network
Now that you have a grasp of how smart home appliances communicate and the devices required to put together your home network, you still need a critical component. You need a means that brings together all your smart devices for easier, seamless communication. Fortunately, here are two alternatives the tech world has to offer.
1. Smart hubs
The smart hub is a gateway that accepts connections from all devices in the smart home network, even from different manufacturers and using different communication protocols. Integrating the different signals from your smart devices together allows easy control over each device from a single interface.
With a smart home hub, you can go beyond just mere manual interactions. The hub allows you to configure your devices so they detect and react to specific situations. For instance, a light sensor will draw your curtains or switch off lights once it detects strong sunlight.
2. Virtual home assistants
You will find numerous smart speakers on the market with voice-activation control. Such voice-controlled modules can perform simple tasks like reading the news, playing music, answering phone calls and even checking the weather.
Once integrated into your smart home network, virtual home assistants make smart home automation a reality. Some third-party devices available on the market include:
· Amazon Alexa
· Google Home
· Apple Home kit
· Belkin WeMo
Where Do You Start?
Fortunately, setting up your own smart home network doesn’t mean you need to overhaul all your current gadgets completely. Instead, start small by choosing a common area so the tech is easily accessible to all members of your family. Next, look at devices you use daily and see how they can complement your daily routine.


Lufthansa has confirmed that it will be the first network airline in Europe to offer broadband connectivity powered by Inmarsat’s Global Xpress (GX) service. The first aircraft will be fitted with the new technology in “early summer 2016”, marking the start of the rollout of high-speed onboard connectivity on Lufthansa’s short- and medium-haul services. The announcement comes three weeks after the successful launch of the Inmarsat-5 F3 satellite, which is the third and final satellite in the GX constellation.
Meanwhile, Inmarsat and Deutsche Telekom have announced a strategic partnership to develop a hybrid LTE-based ground network and S-band satellite network across Europe. Lufthansa has also committed to a flight trial programme of this new so-called European Aviation Network, starting in 2017. FTE reported last year on Inmarsat’s plans to develop a new S-band hybrid satellite/ATG connectivity network across the EU.
Referring to the commitment to develop the European Aviation Network, Andy Sukawaty, Chairman of Inmarsat, explained: “With this integrated network we can meet the need for capacity, flexibility and quality of service, including the ability to expand quickly to anticipate growth in demand.
“The integrated satellite and complementary LTE-based ground network will ensure that Inmarsat and Deutsche Telekom together deliver the fastest, best and most consistent in-flight broadband experience that meets the needs of airlines in this region. Combined with our global GX (Ka-band) and L-band services, we now have connectivity solutions for the cockpit and the cabin of any type of aircraft, flying in any geography.”
Tim Höttges, CEO of Deutsche Telekom, added: “As a groundbreaking innovation we will roll out a powerful terrestrial network based on LTE within the European Aviation Network. This will be the first aviation connectivity network in Europe powered by both LTE and satellite combined. Our technology leadership provides a solid foundation for the best customer experience possible – be that on the ground or in the skies – and enables us to work with the finest partners in Europe and beyond.”
As for Lufthansa, the carrier’s Chairman and CEO, Carsten Spohr, said the commitment to roll out Global Xpress-powered connectivity next year and to trial the European Aviation Network service from 2017 “underlines once again that we are pioneers when it comes to digital services onboard”.
“We continue to strive for excellence when it comes to our passengers’ flying experience,” he added, “and the provision of reliable, consistent broadband connectivity aboard our planes, which will match that of high-speed home broadband in terms of speed and quality, is of extreme importance to us.”

We use audio in a web browser all the time, listening to songs on YouTube or reacting to a sound in a flash game. But upcoming (and to some extent already available) techniques promise more: Interactive, dynamic audio with signal processing and even access to the sample level. Especially the last feature allows for more than traditional audio programming environments, such as Max/MSP or SuperCollider, can offer: Basically you could implement any audio application (or at least any DSP algorithm). Or maybe not?
What are the present (and future) difficulties in programming audio in the web? What is already possible and what needs further web standards and API specifications? Does it all come to Flash or other plugins or can we leave Flash behind some day?
In this multi-part blog series I want to discuss the past, present and future of audio in the web, highlighting already available techniques to do sound synthesis and sound processing in a common browser and showing how to make the web go “beep!”. As I’m quite new in this topic I’m open to any additions and comments.

How much freedom does your wireless network give you?
February 7, 2007
I am happy that my wireless LAN gives me great coverage all around our house and garden. For some people this is not enough, and they get a more mobile device and an always-on data service to stay connected using 3G, for example.
Now these technologies begin to converge as at least one supplier is offering a cellular device which provides a wireless access router to allow you to use your regular laptop or other WiFi enabled gadgets to access the internet. This is designed to go in your car, so now you can blog about the downtown traffic, or reschedule your morning meetings when stuck in a jam.
Available in the US soon, more information about AutoNet Mobile here.

We recently had a blog entry about the Future of Headphones. Today, we’ll look at another ubiquitous piece of audio equipment, the microphone, and what technological revolutions are on the horizon.
Its not a new technology, but the Eigenmike is deserving of attention. First released around 2010 by mh acoustics (their website and other searches don’t reveal much historical information), the Eigenmike is a microphone array composed of 32 high quality microphones positioned on the surface of a rigid sphere. Outputs of the individual microphones are combined to capture the soundfield. By beamforming, the soundfield can be steered and aimed in a desired direction.
This and related technologies (Core Sound’s TetraMic, Soundfield’s MKV, Sennheiser’s Ambeo …) are revolutionising high-end soundfield recording. Enda Bates has a nice blog entry about them, and they were formally evaluated in two AES papers, Comparing Ambisonic Microphones Part 1 and Part 2.
Soundskrit is TandemLaunch’s youngest incubated venture, based on research by Ron Miles and colleagues from the University of Binghampton. Tandem Launch, by the way, create companies often arising from academic research, and previously invested in research arising from the audio engineering research team behind this blog.
Jian Zhou and Ron Miles were inspired by the manner in which insects ‘hear’ with their hairs. They devised a method to record audio by sensing changes in airflow velocity rather than pressure. Spider silk is thin enough that it moves with the air when hit by sound waves, even for infrasound frequencies. To translate this movement into an electronic signal, they coated the spider silk with gold and put it in a magnetic field. Almost any fiber that is thin enough could be used in the same way, and different approaches could be applied for transduction. This new approach is intrinsically directional and may have a frequency response far superior to competing directional solutions.
MEMS (MicroElectrical-Mechanical System) microphones usually involve a pressure-sensitive diaphragm etched directly into a silicon wafer. The Soundskrit team is currently focused on developing a MEMs compatible design so that it could be used in a wide variety of devices and applications where directional recording is needed.
Another start-up aiming to revolutionise MEMS technology is Vesper . Vesper MEMS was developed by founders Bobby Littrell and Karl Grosh at the University of Michigan. It uses piezoelectric materials which produce a voltage when subjected to pressure. This approach can achieve a superior signal-to-noise ratio over the capacitive MEMS microphones that currently dominate the market.
A few years ago, graphene-based microphones were receiving a lot of attention, In 2014, Dejan Todorovic and colleagues investigated the feasibility of graphene as a microphone membrane, and simulations suggested that it could have high sensitivity (the voltage generated in response to a pressure input) over a wide frequency range, far better than conventional microphones. Later that year, Peter Gaskell and others from McGill University performed physical and acoustical measurements of graphene oxide which confirmed Todorovic’s simulation results. But they seemed unaware of Todorovic’s work, despite both groups publishing at AES Conventions.
Gaskell and colleagues went on to commercialise graphene-based loudspeakers, as we discussed previously. But the Todorovic team continued research on graphene microphones, apparently to great success.
But I haven’t yet found out about any further developments from this group. However, researchers from Kyungpook National University in Korea just recently reported a high sensitivity hearing aid microphone that uses a graphene-based diaphragm.
For a bit of fun, check out Catchbox, which bills itself as the ‘the World’s First Soft Throwable Microphone.’ Its not exactly a technological revolution, though their patent pending Automute relates a bit to the field of Automatic Mixing. But I can think of a few meetings that would have been livened up by having this around.
As previously when I’ve discussed commercial technologies, a disclaimer is needed. This blog is not meant as an endorsement of any of the mentioned companies. I haven’t tried their products. They are a sample of what is going on at the frontiers of microphone technology, but by no means cover the full range of exciting developments. In fact, since many of the technological advances are concerned with microphone array processing (source separation, localisation, beam forming and so on) as in some of our own contributions, this blog entry is really only giving you a taste of one exciting direction of research. But these technologies will surely change the way we capture sound in the near future.

Which Xiaomi / Redmi Phone Is The Best DX In 2019?
Redmi Note 7 priced at only 999 RMB, uses a 6.3-inch water drop full screen, 48-megapixel ultra-clear camera, equipped with Qualcomm Snapdragon 660 as other flagship phones. It has a built-in 4000mAh large battery and supports the highest 18W fast charge, truly cost-effective.
Extreme Cost-effective: the lowest price under the same performance, the best performance at the same price.
Redmi Note 7 is the first mobile phone launched by Redmi after its independence. Lei Jun, founder and CEO of Xiaomi Technology, commented that this phone is the new king of the cost performance. It uses Corning's fifth-generation gorilla glass, Lei Jun said that many 3000RMB mobile phones are reluctant to use this glass.
The main advantages of Redmi Note 7:
(1) The average price of a mobile phone with 48 million ultra-clear cameras is 3,000 RMB, but the price of Redmi Note 7 is only 999 RMB.

NetMyth: Internet companies are “free riders”
NetFact: Internet companies collectively pay billions of dollars per year to network operators for Internet connectivity and transport. That money fully compensates the network operators for their network investment. The Internet companies separately spend billions of dollars more for Internet backbone capacity, much of which goes to the telephone companies as well, now the Internet backbone market has also been consolidated due to the Bell mergers with AT&T; and MCI.
Overall, the four Bell companies alone make some 14 billion dollars annually in revenues from selling special access services to Internet content and applications companies, Internet service providers, and other corporate and institutional users of the local network. FCC figures show that this is a highly lucrative business, with returns over 50 percent. All of this return is in addition to the 20 billion dollars a year in fees that subscribers pay network operators for broadband access to the Internet.
* Remember: The reason why consumers spend all that money for broadband access is to reach the rich and compelling content, applications and services that Internet companies spend billions of dollars to create, develop and deploy.
Net Neutrality Matters. Protect the Open Internet.
