If you’re in the market for a Wi-Fi router, then you’ve probably asked yourself, “What do I need a new router for?” or “What features should I look for in a router?” In this blog post, we’ll help you answer those questions and others you may have when it comes to choosing the right Wi-Fi router for your needs.
On the box of every single router, you will see numbers like 2.4 Ghz and 5 Ghz. These numbers indicate the wireless radios on the router.
The 2.4 Ghz radio is suitable for activities that don’t require much network bandwidth like web browsing and replying to emails. Its band is of a lower frequency; while its range can exceed 5 Ghz, it can easily be blocked by concrete walls.
On the other hand, the 5 Ghz band has greater power, but it also has a shorter broadcast range. This option is preferable for video conferencing and other activities that require heavy media upload/download.
A dual- or tri-band router will have both the 2.4Ghz and 5 Ghz radios so that the connection workload can be split between them.
By looking at any router, you will see that there are a number of different network types available. Also referred to as wireless protocols, the four most common types are 802.11b, 802.11g, 802.11n, and 802.11ac. These designations indicate how fast the router can transfer wireless data, with 802.11ac being the fastest.
Newer routers utilize the latest Wi-Fi protocol dubbed 802.11ax. Also known as Wi-Fi 6 or High-Efficiency Wireless (HEW), this new protocol improves upon 802.11ac technology in the following ways:
- Greater throughput speeds (up to 9.6 Gbps)
- Reduced network congestion and expanded client capacity, thanks to Orthogonal Frequency-Division Multiple Access (OFDMA)
- Improved range performance
- Reduced power consumption by network-connected devices, courtesy of Target Wake Time (TWT)
OFDMA enhances network performance by splitting up Wi-Fi channels into sub-channels. Doing this permits up to 30 users to simultaneously use the same channel.
Meanwhile, TWT reduces the power consumption of connected devices by allowing them to determine when and how often they will wake up to begin sending and receiving data. This extends the battery life of smartphones and battery-powered Internet of Things (IoT) devices such as smart thermostats and security cameras.
In communication networks, throughput is the rate at which messages are successfully delivered via a communications channel. A router’s throughput is the speed at which the router is supposed to transmit data to users. To spot the router’s throughput, look for Mbps (or Gbps for cable Ethernet connections). This is usually one of the first things listed on router boxes and specifications.
Keep in mind that if you have a 100 Mbps internet connection but your router can only deliver up to 80 Mbps, then the total speed of your network will be the lower figure. This is why it would be best to get a router with a higher throughput if your internet service provider delivers faster connections.
Beamforming is a feature that’s now standard in mid- to high-end routers. This form of signal technology allows for better throughput in areas with poor or dead signals. Beamforming can help improve the connection quality with devices behind solid walls or in rooms with large amounts of signal interference.
By utilizing this technology, routers can determine weak connections and automatically improve them. While beamforming is available in routers with many network types, it is really only useful with routers running 802.11ac or higher. Those who don’t mind paying a higher price point for an increase in network performance should consider this feature.
Multiple input, multiple output (MIMO)
MIMO is the use of multiple antennas to increase performance and overall throughput. MIMO-enabled routers ensure that more devices can connect to one router with less interference.
When it comes to real-world tests, there is often a slight improvement if the antennas are configured and aimed properly. However, getting a high-end router with six or more antennas may be an unnecessary cost for small businesses.
Quality of service (QoS)
QoS allows the router administrator to limit certain types of traffic. For example, you can use this feature of a router to completely block all torrent traffic or limit it so that other users can have equal bandwidth. Not every router has this ability, but it is a highly beneficial feature for office routers.
There’s a lot to consider when it comes to picking an office router but the process doesn’t have to be complicated. Contact us today so we can evaluate your networking needs and help you find the best setup for your business.

If you have a Michener-issued device on the new Rogers VoR plan, talk and text are unlimited, but MMS messages are charged at a rate of 50 cents each.
What are MMS messages?
MMS messages are any messages sent via your device's text messaging application, that have media in them. This includes pictures, videos, songs, etc. SMS messages are text-only messages, and are still unlimited in the new Rogers plan.
On a BlackBerry: This would include all messages sent via the texting feature that include mixed media such as pictures, videos, songs, etc.
On an iPhone: this would be all "green bubble" messages (messages sent to users without iMessage) that include mixed media such as pictures, videos, songs, etc. A quirk of the iPhone is that this also includes all messages, even text-only messages, sent to groups with non-iMessage users in them. Group messages to non-iMessage users are sent as MMS messages, and will thus be charged accordingly.
Who is responsible for paying for these surcharges?
Usage of the MMS feature and associated charges will be treated the same as any other overage charge. Therefore, the user of the device will be responsible for paying for these excess charges out-of-pocket unless a justifiable business reason for the overage can be provided to the budget manager of that user.
How can I avoid these charges?
If you have a BlackBerry: There is no way to disable the MMS feature on BlackBerry devices. To avoid charges, please refrain from sending anything other than pure text messages using the messaging application on your device. Should you need to send media to another user, please use a service that uses cellular data instead of the MMS feature. Options include Email, WhatsApp, Viber, and similar services.
If you have an iPhone: You can disable MMS messages on your iPhone by following the instructions provided at the article linked: here. Should you need to send media or chat with a group, please use a service that uses cellular data instead of the MMS feature. Options include iMessage, Email, WhatsApp, Viber, and similar services.

I have finally found a document that may give some insight to our Technology:
The presented paper describes a model for the study of a power transformer as the termination of a transmission line with a traveling wave. When the traveling wave running on the transmission line reaches the transformer, it is partly reflected and partly transmitted through the transformer. The voltages on input and output transformer terminals depend on the shape of the traveling wave and on the relation between the transmission line surge impedance and the input and transfer impedance of the transformer. As the transformer impedance is frequency dependent, the responses of the transformer to the traveling waves cannot be determined without knowledge of these dependencies. The model described in this paper is based on measurement of transformer impedance. It considers the frequency dependence of transformer impedance and enables the calculation of voltage on both input and output terminals of the transformer for any shape of the traveling wave on the line connected to the transformer.
Date of Publication: Oct 1997Reflection and transmission of traveling waves on power transformers
We have heard similar approach to: "traveling wave running on the transmission line reaches the transformer", before in Floyd Sweets work: "Consider energy, flowing straight and level down the proximity of a transmission line. The energy does not know the width of the channel through which it is passing."
Does Science know more than its letting on?
Look for the Gaps, fill them with solid, hard data.


Heterogeneously Integrated InP/Silicon Photonics
Introduction – Silicon (Si) photonics research and development started more than 30 years ago and has intensified in the last 15 years as levels of device functionality, photonic integration, and commercialization have all increased. The key drivers for using Si in photonics arise from the quality of wafers and the superior processing capabilities developed and funded by the microelectronics industry. It has the promise to revolutionize the photonics industry in the same way that CMOS design and processing revolutionized the microelectronics industry, by driving down photonic chip cost while enabling higher levels of photonic integration and functionality. Commercialization, so far, has focused on optical communication (Telecom and data center) and biosensing, with a wealth of future application areas, including high-performance computing, automotive (lidar), optical switches, and artificial intelligence.

Matrix NB based on 5g network
on July 18, 2019, at the "pilot! 5g broadband double Gigabit" release ceremony of China Mobile Tianjin company, an almost "zero delay" space dialogue opened the "double Gigabit" network era of Tianjin "Gigabit 5g mobile network + gigabit optical broadband network"
on July 18, 2019, at the launch ceremony of "pilot! 5g broadband double Gigabit" of China Mobile Tianjin company, an almost "zero delay" dialogue across the space opened the "double Gigabit" network era of "Gigabit 5g mobile network + gigabit optical broadband network" in Tianjin
4k, HD, zero delay, multi angle, matrix NB IOT smart water meter based on 5g network, China Mobile Tianjin and Tianjin Yumin gas meter signed a strategic cooperation agreement? There's a story
after a detailed investigation, it turned out that it was China Mobile Tianjin Company and the smart city center of China Singapore Tianjin eco city that jointly released the deployment of mobile 5g network in Tianjin, and achieved landing application results in smart water meters
dual Gigabit refers to 5g mobile network Gigabit and optical broadband network Gigabit. With the "complementary integration" of 5g network and Gigabit broadband, a gigabit network with free switching, seamless connection, high-speed use and extensive stability has been formed, which has opened a new era of "fixed mobile at the same speed and seamless communication", and will boost the digital innovation in the "four major fields" of family, industry, government and enterprise, and city
with the strong support of Tianjin, Tianjin Mobile has built and opened more than 500 5g base stations throughout the city. 5g network has covered the central urban area of Tianjin, the main urban area of Binhai New Area, Zhongxin ecological city, Tianjin port, Xiqing University Town, Haihe Education Park and other key areas. In 2019, Tianjin Mobile will invest more than 1billion yuan to build large-scale infrastructure and promote the full coverage of 5g networks in 4500 communities and 4.6 million households in Tianjin
according to Sun Yang, general manager of the Technology Department of Tianjin saien Energy Technology Co., Ltd., "with the advantages of 'double Gigabit' network, high transmission and large bandwidth, the company has developed intelligent water meters, which will be integrated with other cloud data to jointly serve people's livelihood, energy conservation and emission reduction and other fields. At present, more than 40 have been installed. When the sample height is relatively increased, more than 00 have been installed."
at present, matrix NB IOT intelligent water meters based on 5g networks have been applied in the replacement of fenghuangcheng community, Hexi District, Tianjin. It is reported that this will realize the cloud monitoring of water use data, and at the same time, people's livelihood services such as purchase and repair can be completed through the app with just a fingertip "touch"
in addition, it is also noted that at the launch ceremony, China Mobile Tianjin also signed strategic cooperation agreements with six enterprises including Tianjin Yumin gas meters. Can you imagine that the matrix NB IOT smart gas meter based on 5g network is also planned
Tianjin and the story of the meter industry
in the work report of the Tianjin municipal government on January 14, 2019, Tianjin stated that it would take two years to update the 3.75 million plate corundum business department director of the functional material factory of Chalco Shandong Co., Ltd. for free: household intelligent water meters, and accelerate the construction of smart water
in September 2017, Tianjin Jinran announced that from October 2017, Nb IOT gas meters will be tested in some communities within the jurisdiction of Tianjin Jinran public company, and then nearly 4million residents in Tianjin will be replaced with Nb IOT smart gas meters
recently, fenghuangcheng community, Hexi District, Tianjin was equipped with a matrix NB IOT intelligent water meter based on 5g network
it's not just the gas meter itself. Recently, it was learned that Tianjin fuel China Resources gas had an exchange with a number of domestic gas manufacturers on "how to build an IOT smart collection platform". Gold card and silver card software stood out among many manufacturers, won the trust and recognition of customers, and formally worked together to build an IOT smart collection platform for Tianjin fuel China Resources, Many enterprises have not been able to skillfully apply the impact testing machine to digitalize and lean after purchasing it
iot smart collection platform
with the rapid development of urban gas enterprises, building IOT smart collection platform is not only the requirement of modern management and service of gas enterprises, but also the requirement of increasingly diversified user needs
since its establishment, Jinran China Resources Gas Co., Ltd. has continuously promoted the construction of information technology. With the growth of enterprise business volume, the independent management mode of IOT back-end system of different meter factories has gradually revealed many difficulties, such as difficult operation, management, operation and maintenance, statistics and so on. In response to the increasing diversification of market and user needs, enterprises have put forward more refined requirements in data collection, measurement monitoring, remote regulation, price management and so on
based on the above background, Tianjin fuel China Resources gas has communicated with a number of domestic gas manufacturers. The gold card and silver card software has stood out among many manufacturers, won the trust and recognition of customers, and formally worked together to build a Tianjin fuel China Resources IOT intelligent acquisition platform, making the enterprise more digital and lean with poor crack resistance
based on the business characteristics of Tianjin fuel China Resources gas users, the project team has successively completed the work of system development, system deployment, system testing, etc., and successfully completed the migration of IOT meters to the new platform. Through the establishment of IOT intelligent acquisition platform, the unified management of various meter types, the unified integration and access of multiple meter factory agreements, and the unified integration of multiple platform data of Tianjin fuel China Resources gas have been realized, which has reduced the management and operation costs of gas companies and further improved the management efficiency
not only that, the system also provides more value-added application and management functions, covering equipment management, file management, meter monitoring, consumption monitoring, charge management, statistical reports and other modules, which meet the needs of enterprises for centralized meter reading and unified charge management. The statistical report module provides accurate operation data for enterprises and provides basis and support for managers to make decisions. At the same time, in terms of price management, the system newly supports the calculation of step gas price in an unnatural annual cycle, and supports the expansion of step gas price by population, which is more suitable for customers' business scenarios, and effectively ensures the accuracy of user price management
in the next few years, the number of meters on the IOT collection platform of Tianjin fuel and China Resources gas will exceed one million, and the intelligent management of IOT will be deeply integrated with the reform of enterprise informatization

Drivers or vehicle owners always love feeling secure and safe in their vehicles. It is not uncommon for people to have accidents in the middle of nowhere and there is no help around for them. Or for people to get lost or miss their way in a very remote location.
These are some of the reasons OnStar was developed. It was made to be of great help and benefit to drivers. So, how was OnStar made, how does it monitor your location? Does OnStar have a camera?
Yes, OnStar have a camera. Some features of OnStar make use of a camera but not all subscribers of OnStar will have cameras in their cars.
Does OnStar Have a Camera?
Yes, based on research and other available information, some features of OnStar come with a camera. But this is not in all features, not everyone that uses OnStar will have a camera in their car.
Does OnStar Mirror have a Camera?
Yes, the type of camera OnStar uses is the mirror dash cam. This is for loop recording, parking, and interior monitoring. A search on Amazon for OnStar cameras will provide you with more information.
Can OnStar Record You?
What Does OnStar Record?
A new term of service of OnStar suggests that the company is now permitted to record your location, safety belt usage, safety, the status of the engine, several other data about your car and how you use it.
As long as your OnStar is activated, their advisors cannot listen to your conversations or record conversations you have in your car except you calls an OnStar advisor or when an OnStar advisor calls you in your vehicle.
Does OnStar Track Your Location History?
Sources within OnStar have stated that the device uses Global Positioning System (GPS) technology to assist law enforcement agencies to track down your vehicle.
Even if your vehicle is in a static position, OnStar is able to track the location and send the location to the police to find it.
OnStar also uses this technology, Remote Ignition Block signal that can stop an engine equipped with the device from restarting. In a moving position, OnStar is able to track accurately the location of your car with their tracking device.
OnStar devices are equipped with GPS that transmits the exact location of the car to OnStar. With this, the car owner can monitor and track the location of the car at any time. The device also has features to track speed and direction data.
Can OnStar Track my Car if not Activated?
No. Whenever the OnStar device in your car is out of subscription, it is disconnected from the OnStar grid. Being disconnected from the OnStar grid means that your car is no longer track able by OnStar because the services are on hold till you activate it.
Does OnStar Work when Car is Off?
Yes, OnStar works even when the car is switched off. Interestingly, it also makes use of a technology that can stop a stolen car equipped with OnStar from starting. But if your subscription expires, the OnStar device will be inactive.
As soon as your subscription expires, OnStar transmits a signal to the OnStar device in your car to disable itself.
The emergency button on the device will stop working (a voice will notify you of this) and other automatic features as well will be disabled.
Benefits of Using OnStar
The benefits of using OnStar are:
1. Automatic Crash Response
If you equip your car with the OnStar Automatic Crash Response feature, once an accident occurs, the impact transmits data to an OnStar Advisor that an accident has occurred to your vehicle.
You will be contacted immediately by the OnStar Advisor via the OnStar voice system.
If you cannot be reached or contacted, the OnStar Advisor will relay your information and location to emergency responders (Police, firefighters, paramedics) so appropriate help can be dispatched and provided to you.
2. Turn–By–Turn Directions
OnStar has the service to direct you wherever you need to go. To use this service, you just have to press a button on the OnStar screen and the OnStar Advisor will provide directions on how to get to your destination from your exact location (I know, just like Google Maps).
3. Stolen Vehicle Assistance
OnStar has services that can help the owner of a stolen vehicle recover it. This is the GPS service. It transmits the exact location of the car to OnStar helping it track down the location.
Once it is gotten, the police will be notified and the vehicle can be retrieved. The OnStar Advisor can also stop the ignition from starting remotely and control the speed limit of the vehicle.
4. Hands–Free Calling
This is a very in-demand feature of OnStar that many people love to use because who does not like to make hands–free calls? It does not work like a mobile phone with Bluetooth features though.
You will need to buy a prepaid plan and make calls using the sound system of your car. Thereby eliminating the need for you to take your eyes off the road by looking elsewhere.
5. Maintenance Alerts
This is also a very good benefit of using OnStar. With OnStar, your vehicle’s maintenance is easy and stress-free.
Issues with the transmission, brake system, engine, Engine Control Module, wheel alignment, and others are monitored by the OnStar system effectively.
It also keeps the vehicle owner updated as to when an oil change will be needed and if the tire pressure is low. OnStar also has the feature of notifying you whenever recall notices for your vehicle are published.
6 Wi-Fi Connection
Yes, OnStar has a Wi-Fi feature in cars. If you have the OnStar 4G LTE, your car is automatically equipped with its own Wi-Fi hotspot.
You can connect as many as seven (7) devices to the Wi-Fi right there in your car!! So cool right? The speed is 4G LTE though, which is not bad at all. You stay connected at all times even on the go. This is a major benefit of OnStar.
Nothing gives peace of mind to drivers more than having the ability to remain safe, secure, and connected while driving.
OnStar is one of the features that vehicles offer to provide safety to drivers and riders. OnStar gives every driver a feeling of connection whenever they are in their vehicles. It is worth every penny.

Virtual Private Networks (VPNs) let you establish a secure communications channel between your computing device and a server. After connecting to the server, you could gain access to a private network that has work files or applications, or use the server as a relay point to then access Internet content when browsing from a public network.
There are several reasons for using a VPN: you might need to remotely access information held on corporate servers while travelling or working from home; you might be wary of the insecure wireless networks you’re using; or you might want to access online content that’s blocked on the network you’re connected to but is accessible from the server somewhere else. Sometimes a company will require you to use a VPN, meaning the company will dictate the security and type of VPN you use (for example, your employer). Whereas when you make a consumer decision to use a VPN you’re responsible for making these decisions on your own.
In the wake of Edward Snowden’s revelations, a large number of consumer VPN providers have sprung up, and security experts now often suggest that you use a VPN when accessing the Internet from an insecure network (e.g., a café, public library, or other free Wi-Fi hotspot). This blog post will help you understand what to look for when choosing between different VPN services.

When installing SIP Trunks and VoIP, it all comes down to planning. In brief, a traditional ISDN channel (which has a bandwidth of 64Kbits), connects your telephone system to the Public Switched Telephone Network (PSTN). It allows you to make voice calls but does not allow you to send data. SIP Trunking connects your PBX phone system to the PSTN with an IP network instead of ISDN.
Voice over Internet Protocol (VoIP) is packet-switched telephony across the internet. The packets are often compressed and encoded and may take different paths to the same destination.
Internet Connection: To get the most out of VoIP, you will need an internet connection that offers enough performance to accommodate an appropriate call volume for your company.
Super-fast cable modem or DSL: While these are great for things like browsing the Web or if you work from home, they are often not suitable for VoIP because they provide lots of downstream bandwith but little upstream (away from your network) bandwith.
For VoIP, upstream bandwidth is every bit as important as downstream, particularly if you plan to use more than one phone.
So if you have a large company you would need to consider a high-speed internet connection and make sure you get the Internet connection and VoIP service from a single provider and check out the Service Level Agreement (SLA).
Compare SIP with ISDN and you can see the number of extra features you can have:
In summary, the key to success with SIP comes down to proper planning.

Copper is the most often used material for speaker cables due to its low cost and low resistance. However, because copper oxidizes, it must be adequately protected and insulated. If it is not, it will cause corrosion and electrical failure of the cable. Copper also has some characteristics that make it unsuitable for certain applications.
Speaker wires are the conductor that sends an audio signal from the amplifier to the driver. The two types of speaker wires are balanced and unbalanced. Balanced wires send both positive and negative signals, which are then combined at the other end by a connector or crossover unit. Unbalanced wires only send one signal so they can be used with any number of drivers without needing special connectors. They are more common than balanced wires because they require less wiring work at the installation site.
Balanced connections are considered better quality because the negative signal doesn't get lost in transmission, but this is only true if both connections are made using balanced wires. Otherwise, you are just sending one signal over two different paths and getting two copies of it at the other end. An example of this would be if you had a pair of unbalanced headphones plugged into a jack on one side of the wall and a set of unbalanced speakers connected to another jack on the other side of the wall.
What is the quality of copper-covered aluminum speaker wire? The good news is that CCA wire has the same sound quality as copper wire, which means it is suitable for high-quality sound. The issue is that aluminum isn't as good as copper as an electrical conductor. It has about one-third the conductivity of copper. This means that if you have a circuit with many connections, you'll need more aluminum wire than copper to make up for its lower conductivity.
The other problem with using aluminum wire is that it will tend to pick up moisture. If this wire gets wet, it will act as a resistor and degrade the quality of your signal. For these reasons, we recommend using silver or gold plated aluminum cable for high-quality audio applications.
CCA wire is only rated to handle 20mA per channel at full volume, so if you want to connect two active speakers then you'll need two sets of this wire. One set should be connected to the positive pole of the power supply, while the other set goes to the negative pole.
If you want to use aluminum wire as general-purpose household wiring, you can but it isn't recommended. Aluminum is less resistant to heat than copper, so if you have any circuits that go through a power outlet then you should use copper instead.
Heat resistance and conductivity Copper wires can carry a greater load of electrical power than other non-precious metals, allowing them to utilize less insulation and armoring. They have a strong heat resistance, which eliminates most overloading difficulties. Copper wires are also corrosion resistant. They will not break down in acid or alkaline soil conditions.
Copper has many excellent properties that make it suitable for use as an electrical conductor. It is relatively inert to air and water, does not support bacterial growth, and does not corrode readily. These qualities make copper cables durable and functional for connecting buildings or equipment together or within storage facilities.
The disadvantages of copper include its cost and lack of flexibility. Copper cables are more expensive than those made from other materials because of its high demand and limited supply. Also, copper cannot be used to connect wires that must accommodate movement or vibration, such as those involved in transmitting data between computers.
There are two main types of copper cables: solid and stranded. Both consist of multiple strands of wire wrapped around a core. The different names refer to the fact that the strands in a stranded cable are intertwined with each other while those in a solid cable are not. This difference affects how the cables are manufactured and installed. With solid cables, each strand of wire is first coated with resin, then wrapped with tape to keep the resin out of contact with the metal.
Copper is a critical element used in the manufacture of wire for all types of electronics. It transmits electricity and heat extremely well, therefore it is required in greater quantities than any other metal for mobile phone componentry. To fulfill the world's expanding demand for electronics, its supply must be increased. Copper mines tend to be large, expensive operations using technology that is some years away from being practical for smaller scale use.
In phones, copper provides the basis for both the internal wiring and the connections between components. It is also used in the case as a conductor to connect the terminals together. The quality of copper affects how well it will conduct electricity and heat. Poor quality copper can act as an antenna if it is not handled properly during manufacturing or construction of devices using it. Excessive amounts of copper can be harmful because it can cause lung disease when you are exposed to it over time.
Phones contain small amounts of copper because it is essential for many functions within the device. However, too much copper can damage mobile phone circuitry and this might happen if you buy a new phone and find that it has too much power consumption or has other problems related to voltage drops across its internal wiring.
If you look at your phone's manual under "Copper Contents", there should be less than 1% copper by weight. Also, looking on the packaging may help because some manufacturers include a list of materials used in their products.

Windows Communication Foundation is a Microsoft initiative of building Service Oriented Applications that leverages yesterdays and todays technologies, in fact it complements existing distributed technologies. The WCF (Windows Communication Foundation) infrastructure is built into .NET 3.0/3.5 and can be leveraged for different kinds of communication types/endpoint, that ranges from Message Queue, TCP communication, standard webservices, service based webservices. The most commonly used approach is the Service based where you can host it as .asmx or .svc.
In a typical WCF implementation, we have the following :
- Datacontract. Represents the data that will be wired from one endpoint to the other. Any CLR compliant type marked as datacontract can be serialized and wired over the communication protocol.
- Message Contract : Think of messages as envelopes, that wraps up our data/data contracts over the wire. Our message have a body and header section. It is analogous to SOAP envelope, in-fact it is converted to a SOAP envelope when the message serialization begins at runtime.
- Service Contract : Here is the interface that is marked [ServiceContract] which can be called remotely by clients of the service. In our service, we will implement this interface and provide business functionalities that clients will consume and call remotely. Services can expose one - To - Many endpoints (Listener point), and more than one service operations can be exposed by an endpoint.
- Service Endpoint : Think of an endpoint as message gateways for services that are hosted. A service can be configured to listen for request in different endpoints. A service Endpoint has an Address, a Binding, and a Contract.
- An address that describes the location where messages can be sent.
- A Binding specifies the type of communication that an endpoint can make using protocols such as HTTP, TCP, MSMQ and security requirements such as SSL, WS-Security etc.
- Contract : The binding contract are sets of messages that defines sets of operations that can be accessed by the service clients.
Message Oriented Concept In WCF
I mentioned above that the service contract defines operations that are used to send request and response messages over the transport layer defined by the service endpoint. In a simple client/server architecture, messages can be coupled between sending interface and the receiving end. That is there is a stub and skeleton relationship between the service and the consumers. Although, there is noting wrong in the stub and skeleton approach, that is a client\consumer keeps a stub or proxy of the services that it can talk to. This means when a service changes the client is regenerated using svcutil.exe tool for re-generation of the service stubs.
In an ever changing world of buisiness, we need to build services with simplycity in mind, conformance to changes. How do we allow a generic communication between our service and the rest of the world. Thinking about generic-ability of our services, we need to create an interceptor service that sits in between our clients and services, although the contract binding will be between our client and service, but the address binding will be between our client and the interceptor.
Having understood the basics of the WCF fundamentals, we need to now understand how to pass messages in a generic context.
The Interceptor Pattern
This pattern came into mind when i fell deeply into a WCF scenario that requires changing of service messages or re-delegating a service request to other service other than the requested one. Also you can use this pattern to achieve load-balancing amongst services.
One of the reason's why you might want to use an interceptor pattern is the following :
- Expose a single entry to the entire world with the interceptor/facade.
- Do load - balancing with the interceptor.
- Expose a REST (Representational State Transfer) to the world while your back - end service supports WCF semantics, so you need an interceptor to bridge the gap between the pure xml and soap messages required by the WCF services.
- Manipulating/ validation on the facade/interceptor end before delegating to the actual service.
- A form of clean architecture design pattern
- Securability as single entry is used as the entry point. Security is focused on that single entry instead of all
[ServiceContract(SessionMode = SessionMode.Allowed)]
public interface IRequestDispatcher
[OperationContract(IsOneWay = false, Action = "*", ReplyAction = "*")]
System.ServiceModel.Channels.Message ProcessMessage(System.ServiceModel.Channels.Message message);
Note the ProcessMessage operation in our IRequestDispatcher contract, this operation accepts and return a Message from the System.ServiceModel.Channels namespaces and it is the only operation that we need to generically or intercept message calls from client and server.
You will also note that the ProcessMessage method is decorated with [OperationContract(IsOneWay = false, Action = "*", ReplyAction = "*")]. This is to tell our service that our method (ProcessMessage) can process any operation call from different client, by marking it Action = "*" and ReplyAction = "*" . This is the basic of our interceptor strategy.
The Big Picture
Lets have a simple picture of what we want to achieve. We have two WCF services one accepts a string and returns a string, the other accepts an object and returns a string. This services are our back office operations that is open to services that are within our domain. Assuming we want to expose this services to the entire world, we will end up exposing two services. So, if any of the services changes, that means the entire world will have to change with it, this is quite burden some. So, instead of exposing the two services, we have to expose only one service that is generic to all other services, and this service communicates in REST - FUL manner (pure XML and no soap messaging).
Lets define the big picture of


the transducers, which develop their output the form of electrical voltage or current without any auxiliary source, are called the active transducers. • The output voltage is effected by temperature variations. Transducers and Inverse Transducers. Although most of the transducers produce ultrasounds that have a frequency above 200 KHz, the ultrasounds begin at only 20 KHz. Electrical to audio transducers. [1–3]). ACTIVE TRANSDUCERS Transducers on the basis of methods of energy conversion used, may be classified into active and passive transducers.

What is Hydraulics? EVERY application) must rely on a transducer at some point. The converted form of energy by any transducer can also be mechanical energy, optical energy, chemical energy, electromagnetic energy etc. Thus, minimizes its size. This displacement output acts as input to the potentiometer (transducer) that resultantly provides an equivalent electrical quantity of the applied input in mV. An electroacoustic transmitting transducer produces sound by vibrating a portion of its surface, which therefore affects the molecules in the transmission medium. The output obtained from transducers is always in the electrical form, which is proportional to the measured quantity applied to the device. These two basically shows variation according to the energy conversion technique. resistance, inductance or capacitance changes with the change in input signal, are called the passive transducers. 4) Capacitive sensors or Variable Capacitance Transducers****: These comprise of the two parallel plates between which there is dielectric material like air. An electrical wire 52, preferably a small, very thin flexible cable, is connected to the ultrasound transducer array 42 and to the processing unit 46. These have small accuracy as compared to RTD’s and Thermistors so generally they are not used for high precision work. The transducers that convert the mechanical input signals of the physical quantity into electrical output signals are called as electrical transducers. Disadvantages of Piezoelectric Transducer 4.1. The more common analog transducers perform the conversion to electrical form by … They are utilized for electrical actuation and sensing of mechanical displacements and forces in a wide variety of applications (see e.g. In the small signal regime, PMUTs can be modeled through an equivalent electrical circuit as shown in figure 2. Generally, a transducer with an mV electrical output can be used in laboratory applications. Primary and secondary transducers are categorized on the criteria of methods of applications. Search. iv. As transducers change any physical unit into its electrical equivalent. If the resistance of all the strain gauges is exactly equal, the bridge is said to be “balanced” and no … Electrical amplification and attenuation can be easily done. 3) Wheatstone bridge: It converts the displacement produced by the physical quantity to the current in the circuit. Disadvantages of Piezo Electric transducers •Due to small capacitance and large insulation resistance of the transducer ,the charge leaks away through its insulation resistance. Transducers are any device or element which converts an input signal into an output signal of a different form. There needs an external driving circuit that feeds square wave input to the buzzer. A transducer is the heart of the instrumentation system and can be majorly classified as: Basically, transducers are classified according to the operating principle, uses and the required output.

Together with his team, Robert Schiphorst, director of Schiphorst Telecom, was responsible for all facility management along the route. This included moving parking signs when parking areas were full and ensuring emergency services were on hand as quickly as possible. “We were faced with a huge challenge: our service activities create a constant flow of communication and we had to cover significant distances. Because of the large geographic area concerned, connection to a national network seemed logical, but in practice, full coverage proved impossible.”
Optimal control through 100% coverage throughout the route
Flash Private Mobile Networks advised GroupTalk, a Push-to-Talk app that can be installed on any iOS and Android Smartphone. By setting up groups of employees, such as sector heads, a mobile phone can be used to communicate as if it were a two-way radio. Group communication including all the advantages of a smartphone. And GroupTalk operates independently of the provider used; it even works over Wi-Fi networks, so the solution is simple and flexible to use. Everyone already has a smartphone, which is an advantage, because the users are familiar with the device.
Schiphorst: “With GroupTalk, we achieved 100% coverage throughout the route and there were 400 posts in constant connection with one another. This meant we knew what was happening in every area. A supervisor listened to all the channels, so everything remained under control. And we were aware at all times of where the peloton was located, so we could optimally monitor the race. Even if someone was busy on a call, once it ended all the messages were delivered. GroupTalk worked perfectly for us!”
Schiphorst Telecom and Flash Private Mobile Networks can look back at a successful kick-off of the Giro d’Italia and the use of the GroupTalk Push-to-Talk application. The app created an efficient communication environment and the communication was both smooth and safe.
It is always our goal to add value for our customers. During the Giro d’Italia, we ensured 100% coverage and with that, optimal safety.
If you are responsible for company processes, you will want to be confident that your employees can always communicate at any time of day, from any location. Your own network must always be available.
Because today’s security threats are increasingly sophisticated, you not only need the certainty of a watertight system that secures sensitive information, but you want to achieve the highest level of safety for your employees.

Satellite tracking for criminals
Thursday, 2 September, 2004, 00:28 GMT 01:28 UK
It is the first time a European country has used satellites to monitor the movements of offenders.
Convicted burglars, robbers and car thieves will be fitted with an electronic device that can be tracked by satellite 24 hours a day.
The trials are in Greater Manchester, West Midlands and Hampshire.
The electronic device will be monitored by a control station which records the location of the offender to within a few metres.
If the offender strays into an area they are excluded from the police are alerted.
The system will also be used to prevent sex offenders going to playgrounds and schools and to stop people convicted of domestic violence from approaching their victims.
Offenders will be required to wear the device as part of a community sentence, or as a condition of their release from prison.
Initially, the system will be used to track up to 120 offenders at any one time, but if the technology works, the Home Office will use it to monitor the 5,000 most prolific offenders in England and Wales.
Home Secretary David Blunkett will launch the trials in Greater Manchester with correctional services minister Paul Goggins at the monitoring centre.
Mr Blunkett has earlier called the scheme a "prison without bars".
The electronic tagging which the government currently relies on is only able to set off an alarm when the offender breaches a curfew.
If a criminal walks out of the house after their curfew an alarm will sound at a central control room, where operators then notify police.
However, under this system there is no way of knowing where the criminal has gone.

Internet-of-Things (IoT) refers to connecting all the things in the world around us to the internet and making them “smart”. The range of IoT devices is broad and can include homes, automobiles, farms, buildings, and wearable medical devices, just to name a few. On the Internet-of-Things, some of the “things” collect and send information, some receive information, and some do both. The information being sent and received is usually a physical parameter of the world around us, such as temperature, pressure, image, voice, velocity, humidity, etc. To collect such information, IoT devices utilize sensors that automatically measure physical parameters and convert them to electric voltages and/or currents which can then be processed more easily using circuits and computers. In a sense, sensors behave similarly to what our sight, hearing, smell, touch, and taste do in helping us understand the world around us. The IoT devices also include a small computer which is considered the brain of the system and processes the information coming from the sensors. Eventually, the IoT devices act based on the processed information to control the outside world.
This cluster provides hands-on experience in working with IoT systems and develops skills necessary for building wearable consumer devices, wearable healthcare devices, and residential IoT systems. The goal of this cluster is to help you acquire the knowledge and confidence to develop your own IoT project regardless of your background in programming or prior familiarity with embedded systems.
