Communication is by far the most important way to grow, survive, and build successful relationships as a person. When you are someone with a disability like a speech disorder communication to others and with others can be rather frustrating. There is nothing like being involved in an engaging conversation, it’s one of the things that make life fulfilling. There are several tech-savvy tools out there that allow speech-impaired individuals to be able to converse with ease with their, peers, coworkers, families, or whoever they may have a question for. Below we discuss three that are simple to attain and simple to use.
Those with speech disabilities never have to worry about being mute or left out of the conversation with today’s modern technology. Text-to speech software like Notevibes allows individuals to type what they want to say into the device that they are using and the software will read it aloud. These types of software tools are not limited to one language, they can translate words in any language with human characteristics like pauses, male or female voices, different speeds, and pitches. Text-to Speech software can be used on more than just your computer. They can be used on any mobile device as there are text-to-speech apps as well.
Similar to text-to-speech software, chatbots are another form of software that can help those who have a hard time speaking, create a human conversation on the computer. The chatbots, however, can analyze questions and answers to the conversation on their own and the person on the receiving end has to choose an answer. Users can either communicate by voice or using the chat interface. The only issue that users seem to come across is when the chatbot misunderstands the context of the speech when trying to mimic human interaction. Chatbots are heavily used on phones and mobile devices. Those with speech disabilities can use them on programs like WhatsApp, Slack, FB Messenger, and more. This allows those with speech disabilities to converse with family, friends, and even people from around the world just like everyone else.
As a child not being able to communicate can be stressful and discouraging both at home and in the classroom. For children learning with speech disabilities, there are several augmentative communication apps that can ease the process. Augmentative communication devices are tools that children can use that come with different systems, and strategies to help them to communicate or to encourage them to talk. Devices like Pocket Go Talk may include pictures with different signs or sign languages, to help them communicate to others what they may want or need. If your child is a bit older and is interested in smartphones or tablets augmentative communication apps like communication for iPad or Touch Chat are available. Apps like these allow those who are speech impaired to text others by using symbols and natural-sounding text-to-speech filters. This allows them to have as much as normal teenage life as anyone else in their school or home environment.


WIRELESS BROADBAND NETWORKS
Wireless broadband is a fairly new technology combining the two aspects i.e. “wireless” and “broadband”.
Communication channels (paths) are grouped into 2 basic categories- narrow band and broadband, depending on their transmission speeds:
Narrowband or baseband are used for handling low data volumes since they provide low speed transmission rates and hence are adequate for low-speed devices like telegraph lines and low speed terminals. Commonly used for telephone voice communications and for data communications by the modems of PCs and other devices.
Broadband or wideband channels are used when large volumes are to be transmitted at high speed. This data communication system handles high volume of data and can be used for high speed computer to computer communication or for simultaneous transmission of data to several different devices. There are different types of broadband access technologies, such as cable, DSL, powerline, satellite, and wireless.
Data can be transmitted through wired or wireless media. Wireless networks can cover wide geographic areas efficiently. Wireless is being adopted for many applications: to connect computers, to allow remote monitoring and data acquisition, and to provide a solution for environments where wires may not be the best solution. Wireless systems are typically slower than land-based, wire-line networks.
BW is an emerging wireless technology that allows simultaneous wireless delivery of voice, data, and video. It provides high-speed wireless internet and data network access over large distances. BW is considered a competing technology with Digital Subscriber Line (DSL). It is generally implemented in metropolitan areas and requires clear line of sight between the transmitter and the receiving end. What is "high" speed is always a changing number.
Through BW, networks of varying sizes can be deployed in places where it would be expensive to run wires. Because trenches do not have to be dug, there may be less overall disruption and visual impact to communities. Particularly for rural areas, wireless technologies may enable less burdensome service at lower cost.
BW falls into local and wide area categories:
Wireless Local Area Networks (WLANs), such as the Wireless Fidelity (Wi-Fi) that is a high frequency network, transmit their signals within several hundred feet. WLANs are implemented as an extension to wired LANs within a building and can provide few meters of connectivity between a wired network and the mobile user. A person with a Wi-Fi enabled device such as a PC, cell phone or PDA can connect to the internet when in proximity of an access point.
Wireless Wide Area Networks (WWANs) such as WiMAX span several miles ensuring interoperability between devices, networks, and regions. WiMAX is defined as Worldwide Interoperability for Microwave Access.
Besides BW, Bluetooth is another wireless technology for low-cost, short-range wireless links and transmission of digital voice and data between mobile PCs, mobile phones, and other portable handheld devices, and connectivity to the internet. Bluetooth is widely used for hands-free cell phone operation, including wireless headsets. It can also be used to transfer data between cell phones and computer.


The engineer visit has finished. The engineer reset the broadband and I'm waiting on the 10 day stabilisation period now. He also said that I'm too far away from the fibre cabinet to recieve the minimum guaranteed download speed. Should I send back the test router (Wi-Fi Hub) since my current Super Router wasn't the problem?
I tried another speed test on TalkTalk's website with my laptop connected to the router by ethernet cable. The speed was 51.7Mbps so no improvement. The engineer said the speeds I'm getting now are the highest my connection can support after stabilisation, and that it wouldn't be able to reach the guaranteed minimum speed. I'll send the old router back with the returns bag.

tristate "High-availability Seamless Redundancy (HSR & PRP)"
This enables IEC 62439 defined High-availability Seamless
Redundancy (HSR) and Parallel Redundancy Protocol (PRP).
If you say Y here, then your Linux box will be able to act as a
DANH ("Doubly attached node implementing HSR") or DANP ("Doubly
attached node implementing PRP"). For this to work, your Linux box
needs (at least) two physical Ethernet interfaces.
For DANH, it must be connected as a node in a ring network together
with other HSR capable nodes. All Ethernet frames sent over the HSR
device will be sent in both directions on the ring (over both slave
ports), giving a redundant, instant fail-over network. Each HSR node
in the ring acts like a bridge for HSR frames, but filters frames
that have been forwarded earlier.
For DANP, it must be connected as a node connecting to two
separate networks over the two slave interfaces. Like HSR, Ethernet
frames sent over the PRP device will be sent to both networks giving
a redundant, instant fail-over network. Unlike HSR, PRP networks
can have Singly Attached Nodes (SAN) such as PC, printer, bridges
etc and will be able to communicate with DANP nodes.
This code is a "best effort" to comply with the HSR standard as
described in IEC 62439-3:2010 (HSRv0) and IEC 62439-3:2012 (HSRv1),
and PRP standard described in IEC 62439-4:2012 (PRP), but no
compliancy tests have been made. Use iproute2 to select the protocol
you would like to use.
You need to perform any and all necessary tests yourself before
relying on this code in a safety critical system!

When businesses consider which communication channel to use when engaging customers, text messaging (SMS) is at the top of the list. Known as A2P messaging, this process of connecting with consumers via application messages is skyrocketing. To that point, 1.7 trillion SMS messages are expected to be sent by companies in 2018, according to Portio Research.
The reasons behind this growth? Simply put, A2P SMS is the ubiquitous, cost-effective, secure, trustworthy inevitable and direct channel for businesses to communicate with their customers. And, there is a wide range of use cases to back that up. But, just how much can this communication channel improve multichannel business and relationship practices?
Here are five ways in which A2P SMS benefits the retail and ecommerce industries.
It’s stickier than email. Not only do some 7.3 billion people send SMS message regularly, but when users receive messages they also read them quickly. SMS has an open rate of 99% and 90% of consumers read an SMS within the first three minutes of receipt, while just 36A% average open rates for emails.
Flexibility to reach one or many customers. When your business wants to keep a target group informed or you need to handle mass traffic, one-way messaging is available. But when you need bi-directional communication to create dialogue with your target group you can opt for the two-way messaging. In both cases, make a memorable campaign by using a specific number /short code or make it unique by using your brand name in the message header.
A reliable customer lifecycle go-to tool. Variety of ecommerce platforms and A2P SMS create a unique synergy that gives customers the convenience and instant interaction. A2P SMS is used for authorization, authentication, product information, order notification, reminders, coupons, vouchers loyalty programs.
After a customer is hooked, it can be a handy customer service tool. It’s a perfect vehicle when a call-back request is necessary, you want to offer account status information, a customer must make a service request or you want customer feedback.
During the operations phase, texts are equally valuable. SMS offers a simple way for placing orders, password reset, delivery updates, stock availability reports and, of course, order, payment or shipment confirmation. It’s also worth mentioning that all of this can be done with the ability to track, making it easy to know whether customers are getting the message.
The simplest way to provide service notifications. A2P SMS is the most streamlined way to deliver service details in the retail/multichannel world. A consumer orders a product at the POS and registers with a cell phone number. Then a consumer receives a text when the product is ready for pick up. Straight to the point and no hassles.
Fast, safe and reliable. Top-end A2P providers can handle time- and business sensitive A2P messages through established direct connections to mobile network operators. In addition, fast delivery is a huge plus thanks to short latency and high throughput rates.
With the retail landscape shifting at a rapid pace, it’s imperative that companies in this space have a communication channel that can navigate those changes. Whether it’s the ubiquity of text messaging or it reliability, security and cost-effectiveness, A2P SMS is a solid choice.

The impact of trust on the adoption of the Internet of Things (IOT)
The speed at which the internet has evolved — and continues to evolve — is nothing short of astonishing. Over the course of little more than a couple of decades, mass internet usage has rapidly shape shifted in both form and function.
First, came web browsing and email capability via desktop computers. Then came the mobile web revolution, with the normalization of internet-connected phones, tablets and e-readers. Then, connected TVs, smartwatches and fitness trackers came onto the scene and once again revolutionised daily habits and lifestyles in previously unimaginable ways.
And most recently, the so-called ‘Internet of Things (IoT)’ is once more pushing the boundaries of perception around both the individual and collective role of the internet.
Often touted as the next significant technological revolution of our generation, the Internet of Things is already changing our homes, workplaces, and public infrastructures in pretty exciting ways. But for all the opportunity that it represents, a number of consumer concerns exist surrounding IoT. Especially in relation to connected home products.
The evolution of this latest wave of connected tech — and the valid concerns attached to it — has obvious relevance to retail industries. Let’s take a closer look at rise of connected tech, and consider what needs to happen to build trust among a sceptical consumer base.
What exactly is the Internet of Things (IoT)?
Put simply, The Internet of Things, describes the network of physical devices capable of communicating, exchanging data, and executing automated tasks.
In everyday terms, that basically means the development of useful, internet-connected products and systems, such as:
- at home: heating thermostats that can be controlled remotely using mobile devices
- in the shops: retail ‘beacons’ that use bluetooth to send automated location-based offers and alerts to passersby
- in manufacturing: completely automated factories and warehouses, operated by a network of robotics, sensors and databases ‘talking’ to one another
On the face of it, this new horizon of connected tech offers an almost Utopian promise of untold efficiencies and improvements in the way that we operate as individuals, companies, public institutions and governments.
According to a Business Insider study, 24 billion IoT devices will be used by 2020. That’s more than four devices per human on earth.
The trust problem that’s holding back the connected home market
The same Business Insider report also lays out some interesting trends in industry adoption of IoT powered products and systems. The top level takeaway is that the majority of IoT usage has been dominated by businesses and governments — but less so, by consumers in the home.
For instance, beyond the above mentioned use of IoT in manufacturing:
- agricultural companies are using sensors to collect data for precision farming
- doctors are increasingly adopting wearable tech to remotely monitor patients’ health
- use of in-car trackers by insurance companies to calculate performance-based premiums has become commonplace
- installation of smart meters in homes are allowing utility companies to accurately monitor power usage
Also, in the world of government, investment in IoT by urban planners is soaring, with an estimated 6 billion connected devices predicted to be used as part of city infrastructures by 2020. And of course, there’s the obvious use of connected technology in government defence, via drones and robot-operated weaponry and equipment.
In comparison, consumer appetite for IoT devices has been more mixed.
Whilst the connected car market appears to have burst into life over the past couple of years, it’s in the home that some consumers are less convinced by the IoT revolution.
Chief among concerns are security and privacy. And understandably so.
Whilst products released onto the market are undoubtedly impressive, many would agree that the Internet of Things is still in its infancy — with compatibility issues between devices still hampering user experience. And even more urgently, security issues and concerns loom large. And where security is a concern, so is privacy.
Not surprising then, that many of us are still a little hesitant to have multiple devices in our homes — from fridges, to TVs, mirrors and wearables — that are capable of tracking and monitoring our every move. The potential threat posed, if that kind of power ever gets into the wrong hands, is obvious.
But besides ‘outsider’ infiltration of such data, the intentions of the actual product manufacturers and sellers are themselves under scrutiny, as brands face an uphill challenge in convincing consumers that they can be trusted to responsibly handle consumers’ personal data.
The fact is, many consumers still need reassurances that the immensely powerful positions companies now hold by owning access to such a wealth of personal data, won’t be exploited for commercial gain.
What needs to happen to build trust in connected home products?
If retailers of connected home products are to win over concerned consumers, three major issues should be the focus of efforts…
The more open brands are about how they collect, use, and share consumers data, the more likely they are to cultivate trust.
A set of transparent data and privacy policies should clearly communicate what data is collected from customers, how and where it’s stored — plus, any wider possible uses of that data.
In addition, customer advice on best practices for data protection, such as setting a secure custom password and using encrypted Wifi networks, should be promoted by companies to help reassure and educate customers.
Security infrastructure investment
It seems that the newer the technology, the more vulnerable it is to security breaches and malicious attacks. In other words, in many cases the pace of technological advancement is outstripping the development of adequate cyber security solutions to support it.
With there already having been a number of infamous examples of connected tech being hacked, there are increasing calls for a standardised approach to securing IoT devices.
Cisco recently published its proposed framework, Securing the Internet of Things, in a bid to bring this about sooner rather than later.
Supporting compatibility through consistent standards
Related to the previous point on improved security, is overall compatibility issues between connected devices. In short, the more fragmented and disjointed the communication between various devices and networks are, the more easily hackers are able to pick holes and do harm.
But on a more basic level, as far as consumers are concerned, the more popular connected home devices become, the greater the expectation will be to have them all talking to each other and seamlessly performing complex tasks at the user’s whim.
As this Wire article discusses, the need for a reliable and robust set of common standards is increasingly urgent, if brands are going to deliver on the kinds of experiences and lifestyles already being promised to consumers.
There’s no doubt about it, the age of connected technology and the Internet of Things feels like a genuine new dawn for how we will as human beings, individually and collectively, communicate and get things done in the future.
However, it’s already not been without a few bumps in the road. Trust around privacy and security are chief among consumer concerns that are acting as barriers to mass uptake and everyday usage — as well as more basic teething problems related to compatibility and user experience between products.
It’s predicted that $6 trillion will be invested in IoT products by 2020. It's likely it will have an impact on our lives in yet unforeseen ways. Tackling the trust and security concerns is key to ensuring we fully embrace the opportunities.

A PING is used to determine whether the server can be reached and is connected to the internet. To do this, small data packets are sent to the server and the response is then evaluated. This is usually the first step in error diagnosis to rule out connection problems.
The Ping Monitor sends a PING and triggers an alarm if there is no response or it takes too long.Ping Monitor
SSH is the most widely used service to connect to a server’s console or to exchange files with the server. A connection to the server is usually not possible without an executable SSH server.
The SSH Monitor checks whether the SSH service is available and responding correctly.SSH Monitor
File transfer via FTP is frequently used. The availability of the FTP service is particularly important where files are regularly transferred as part of system integration.

People love video, wherever they get it – from a computer or TV. Until now, however, we receive one information through TV, the other – through a PC. Together with the world’s leading carriers such as Comcast and AT&T, Deutsche Telekom and British Telecom, Softbank BB and China Telecom, Cisco is developing new technologies that give TVs the interactive multimedia features of the Internet. On the other hand, purely television content is beginning to be transmitted through other communication channels to new user devices.
We like the term “visual networking” because it captures the hard fact that modern people no longer want to passively stare at the TV screen. Video is becoming one of the most important functions of the Internet and all other communication and entertainment services. Cable television operators such as Comcast and carriers such as AT&T are increasingly offering subscribers multimedia television services that link all types of content and all types of user devices together. These services are based on video technologies. We are at the very beginning of this journey, but today more and more operators are starting to use the IP protocol for video networks.
The use of television and video technologies in IP networks facilitates the introduction of video-on-demand (Void) services and virtual video recorders. New technologies allow the viewer to watch whatever he wants, at any convenient moment. In addition, it becomes possible to deliver to the TV screen all the abundance of information that is stored on the World Wide Web. This means you can watch YouTube video clips on your large plasma or LCD TV and share your photos with family and friends.
It is clear that the PC will remain the best way to run some multimedia applications, but the TV can display high-definition video. For multiplayer games, a large screen and high resolution, which is provided by television receivers, are best suited. Another example of the use of visual networks is an interactive chat on a television screen while watching a television program. Experience in the development of Web 2.0 technologies and social networks shows that we cannot predict which of the new applications will become the most popular.
Therefore, the new generation of television workers must offer not only high-quality movies and TV shows, but also connect viewers to video content and a wide variety of electronic devices, Internet applications and multimedia programs. This is the essence of visual networks. People like not only the Internet, but also the home TV, so the video is gradually turning into the same “killer application” that will connect the TV world and the PC world into one. People want it, and we will give them that opportunity.
Delivering video (especially high resolution) to the big screen is no easy task. Its complexity is an order of magnitude higher than that of tasks related to voice transmission over IP networks. Simply connecting your TV to a broadband network will not satisfy most users. The “last mile” of the Internet lacks sufficient bandwidth and does not support the specialized (and highly complex) mechanisms required to carefully process and transmit video signals over the network. And without this.
it is impossible to maintain high quality video. Only the largest operators have such opportunities. As a rule, these same operators provide broadband channels for Internet access. Today they are actively expanding the bandwidth of their channels in order to deliver video content to subscribers. Thus, the leading operators have already started building visual networks.
High definition television (HDTV) requires five times the bandwidth of a conventional definition digital signal. Therefore, the wider the bandwidth in the new television networks, the better. That is why we are developing new routers and switches, which have essentially become supercomputers for visual networks.
But bandwidth isn’t everything. As already discussed, high-definition video networks require complex control systems to maintain flawless picture quality and service reliability. These characteristics, commonly referred to as “quality of service” (Qi’s), are best implemented at the network level. Cisco offers all the tools you need to run the new visual networks seamlessly.
The task is not only to deliver the video signal to houses and apartments. It is not enough for a modern user to simply switch channels – he wants to have full control over what, where and when he will watch. Therefore, the network technologies of our subsidiaries Scientific Atlanta and Linksys help broadcasters harness the power and power of the Internet to support video-on-demand services, virtual digital video recorders, and interactive services that include connection to personal computers and other home electronic devices.
We asked our TV service provider customers what their top priorities were to address first. In response, we heard very unexpected things. First, they all started talking about the gateway. Today, many people use a modem that is not widely compatible to receive broadband services. The only function it supports is connection to a personal computer. Therefore, we set ourselves the task of developing, together with operators.
a “home gateway” – a new type of device that will not only give the user a broadband channel, but also help connect him to all home devices, including TVs, music systems, game consoles, etc. Our first home IP gateways were showcased at CES-2008 and will be on the market soon. Their main goal is to make it easier to access the Internet and deliver any content and services to all home devices. Broadcasters are very fond of such gateways because they allow broadcasters to provide millions of users with a vast array of new entertainment and communications services.
Another new development from Cisco is a hybrid set-top box that not only supports analog, digital, high-definition television, and video-on-demand services, but also provides viewers with access to video streaming services offered on Web sites. Now this content can be delivered to both PC and TV, which is why the set-top box is called “hybrid”. Like the gateway, the new set-top box completely changes our understanding of television. The telecommunications company will no longer be a telephone, cable and broadband company, but will be able to provide the subscriber with all services at the same time. The main thing is to make these services simple and attractive. For this, new home gateways and hybrid set-top boxes are being developed.

How to Choose the Right RF Power Amplifier?
RF power amplifiers play a crucial role in RF communication systems. Similar to other amplifiers, RF power amplifiers amplify small microwave signals to achieve high-power output. Due to the many important features and specifications of amplifiers, selecting the right one is a challenging task for engineers. In this guide, let's explore key indicators for RF amplifiers and learn how to choose the right one for your application.
1. Operating Frequency and Bandwidth:
Operating Frequency: The number of periodic changes in a signal, usually measured in Hertz (Hz). For RF power amplifiers, it is the frequency of the input signal and the frequency at which the amplifier should operate within its working bandwidth.
Bandwidth: The range of frequencies within which the RF power amplifier can operate effectively, typically measured in Hertz (Hz). It indicates the amplifier's capability to efficiently amplify signals over a specific frequency range.
The chosen bandwidth should encompass the frequency range of signals designed for transmission to ensure optimal performance across the entire frequency spectrum. The selection of the working bandwidth directly influences the amplifier's compatibility in different systems and applications. A broader bandwidth often makes the amplifier more versatile, allowing it to adapt to signals of various frequencies. For instance, if your application requires coverage in the frequency range of 1 GHz to 2 GHz, selecting an amplifier with a center frequency within that range, such as 0.5 GHz to 2 GHz, along with sufficient bandwidth, is advisable.
2. Gain and Output Power:
Gain: The ability of the RF power amplifier to amplify signals, expressed as the ratio of output signal power to input signal power, usually in decibels (dB). Gain can be positive, indicating an increase in signal strength, or negative, indicating a decrease. Amplifier gain varies with frequency, with higher frequencies corresponding to higher losses (gain is not linear across the entire frequency range).
Output Power: The signal strength generated by the RF power amplifier, typically measured in watts (W). For communication systems, sufficient gain and output power are crucial to ensuring signal transmission over long distances.
While gain increases the strength of the input signal, leading to a corresponding increase in output power, it's essential to note that an increase in gain does not necessarily result in a linear increase in output power. This is because amplifiers usually have a saturation point, where the output power reaches its maximum and can no longer increase linearly. Beyond the saturation point, further increasing input power may cause nonlinear distortion.
In communication systems, appropriate gain and output power are key to ensuring signal transmission within a specific range, influencing communication distance and signal quality. In radar applications, sufficient output power is necessary for detecting targets and obtaining accurate measurement results.
Selecting an amplifier with the right gain and output power ensures it provides sufficient signal strength while meeting system requirements. For example, an amplifier may have 20 dB gain and 30 dBm saturation output power, ensuring it meets your communication range needs.
Linearity refers to the ability of an amplifier to maintain a linear relationship between the response of the output signal and changes in the input signal. In linear systems, the variation in the output signal should be proportional to changes in the input signal. Linearity is typically expressed as a percentage or in decibels (dB). Better linearity means the amplifier can maintain accuracy in the output signal over a wide range of input signal levels, while poor linearity may lead to signal distortion and nonlinear effects.
The nonlinearity of an amplifier is mainly manifested as distortion, including harmonic distortion and intermodulation distortion. These distortions introduce frequency components in the output signal that were not present initially, leading to a decrease in signal quality. When the input signal is large, the amplifier may saturate, meaning the output signal can no longer increase linearly, resulting in signal truncation and significant nonlinear distortion.
In wireless communication systems, linearity is crucial for ensuring the quality of transmitted data signals. Better linearity helps maintain signal accuracy and reduce error rates. In radar applications, linearity is critical for maintaining the accuracy and precision of target detection, especially in complex radar environments.
For example, an amplifier with -40 dBc (harmonic distortion at negative 40 decibels) indicates that harmonic components relative to the main signal in the output signal are at negative 40 decibels. This indicates that the amplifier can maintain a low level of harmonic distortion even at higher input power levels, demonstrating good linearity performance.
4. Noise Figure:
Noise figure is a crucial indicator measuring the introduction of noise by an RF power amplifier. It represents the additional noise introduced by the amplifier itself relative to the gain of the input signal. Noise figure is usually expressed in decibels (dB) and is defined as the ratio of output signal-to-noise ratio to input signal-to-noise ratio. The noise figure is related to the electronic components, circuit design, and processes within the amplifier. Excellent amplifier design can minimize the noise figure. The noise figure is also related to the operating temperature of the amplifier, as an increase in temperature can lead to an increase in internal electronic component noise. A low noise figure means that the amplifier introduces relatively small noise, contributing to maintaining high signal quality. In applications where signal quality requirements are high, such as communication systems, a low noise figure is crucial. If an amplifier has a noise figure of 3 dB, it means that the noise introduced by the amplifier is equivalent to adding 3 dB of additional noise to the input signal. Lower noise figure values, such as 1 dB or lower, indicate that the amplifier introduces very little noise and are suitable for applications with extremely high signal quality requirements, such as satellite communication and RF front-end.
5. Impedance Matching:
Impedance matching refers to the adaptation of impedance between the RF power amplifier and the input and output systems it is connected to, maximizing signal transmission while minimizing signal reflection. Ideally, impedance matching makes the input and output impedances of the amplifier equal to those of the connected system, achieving maximum energy transfer. Determining the impedance of the input and output systems connected to the amplifier is the foundation of impedance matching. The design of the amplifier itself also influences impedance matching. Impedance mismatch may lead to signal reflection, causing some signals to be reflected back to the amplifier, affecting signal transmission efficiency, and increasing power consumption. Impedance mismatch can also result in degraded amplifier performance, increasing signal distortion and reducing gain. If the output impedance of the amplifier is 50 ohms, and the system load impedance is also 50 ohms: In this case, impedance matching is ideal because the input and output system impedances are equal to the amplifier's impedance. This maximizes signal transmission, reduces signal reflection, and improves system performance. VSWR is an indicator used to measure signal reflection and is closely related to impedance matching. The smaller the VSWR, the less signal reflection, indicating better impedance matching.
6. Power Consumption and Heat Dissipation:
Power Consumption: The total amount of electrical energy consumed by the RF power amplifier during operation, usually measured in watts (W). Power consumption is the result of the energy loss produced as the current passes through the amplifier circuit, affecting device battery life, power requirements, and overall system efficiency. Low power consumption is crucial for applications relying on battery power or requiring high energy efficiency. Reducing power consumption helps extend battery life, decrease system heat generation, and aids in designing more energy-efficient systems.
Heat Dissipation: The heat generated by the RF power amplifier during operation. When electrical energy is converted into heat energy, it is released into the surrounding environment in the form of heat. Heat dissipation is usually measured in watts (W). Controlling heat dissipation is crucial for maintaining the system's temperature within a reasonable range. Excessive heat dissipation can lead to device overheating, impacting system performance, lifespan, and potentially causing safety issues. Power consumption and heat dissipation are closely related because power consumption is the result of electrical energy being consumed in the circuit, and this energy is ultimately released into the environment in the form of heat. High power consumption typically leads to high heat dissipation, so design considerations include thermal management measures such as heat sinks and fans to ensure effective heat dissipation during high loads, reducing the impact of heat dissipation on the system. Optimizing circuit design, adopting advanced semiconductor materials and processes can improve power consumption efficiency. Dynamically adjusting power levels based on changes in system load helps reduce power consumption during light load conditions.
In conclusion, the choice of an RF power amplifier depends on many factors. Considering the key indicators mentioned above and selecting an RF power amplifier suitable for specific application requirements will help improve system performance and reliability.
RF power amplifiers play a crucial role in RF communication systems. Similar to other amplifiers, RF power amplifiers amplify small microwave signals to achieve high-power outpu...
In the dynamic realm of the electronics industry, thermal management is increasingly critical. This emphasis is particularly evident in RF power amplifiers, where the conversion...
In simple terms, a solid-state power amplifier is a module that integrates and packages circuits with amplification functions to amplify signals.

|Hey everyone, here's my problem.|
I've got a TV and internet modem (or router? not sure what it's called. I plug my internet into it with a coax cable and it sends out wireless for my laptop) in my room and I am trying to make it so that they both will work at the same time. My issue is that I only have one coaxial output in the room.
I've found a powered splitter lying around the house and I have plugged it so that it goes Jack -> cable -> splitter -> and then one cable to my TV and one to the internet. When I do this, TV works perfect and when I'm on my laptop I have a network (The network appears on the list of networks and it says I am connected to it.) but my internet doesn't work. Any ideas why this might be?


The Pedestrian Cross Safety (PCS) solution is a system of traffic lights that indicates the presence of pedestrians crossing to forklift drivers.
Pedestrians are fitted with a series of tags or transponders which, emit light signals that are detected by an activator. Subsequently, the lights indicate the presence of pedestrians in the vicinity.
- Detection of trucks in the proximity of the traffic light
- Easy installation
- Durable and robust system components
- RFID activator AC-50 – trigger a traffic light at the crossing
- Traffic light
- Personal tag T-10 – worn by the pedestrian to trigger the traffic light on approach
How it works
|Pedestrian triggers a signal using an Activator AC-50
With this setup a pedestrian will not be detected when in any other area of the facility


ICO Global Communications has announced its launched a new satellite that will allow it to start offering new mobile services later on in this year. The satellite, called ICO.G1, went up yesterday from Cape Canaveral, and reached its orbit later that afternoon.
The satellite will let ICO provide services including mobile TV, navigation and emergency assistance service “to be known as ICO mim (mobile interactive media)” across the US, Puerto Rico and the US Virgin Islands.
According to the Washington Post, the company reckons its mobile TV service will be different to others on the market because it will reach even the most remote parts of the US. Add in the two way communications the standard allows, and it looks like ICO has an interesting service on its hands. Don’t expect it to turn up on your mobile any time soon – the company is using a standard that hasn’t really been adopted yet.


Mobile Network Operators (MNOs) require substantial data capacities for core and trunking services, much of which uses fibre/cable.
The fibre/cable is susceptible to reliability issues. For rural areas, microwave/satellite is typically used for backhaul. Satellite links can be a highly reliable backup, but can be expensive.
Fibre restoral requires the transfer of traffic to satellite link(s) for fibre outages. The satellite link OPEX can be reduced by using a bandwidth on-demand technology. The scale matters; the more circuits backed up, provides more favourable OPEX. Let’s examine a system level approach for cost-effective satellite-based restoral.
Dimension Bandwidth Pool Capacity
If a restoral service exists, there can be multiple satellite operators, multiple contacts per operator, multiple transponders across bandwidth segments with linear and circular polarisation, and partial and full transponders. The objective is to optimise capacity; not all of it may be required to provide restoral services.
In greenfield designs, capacity must be located on satellites that cover the areas with the fibre nodes. With large service areas, locating satellite capacity can be challenging. Available satellite footprints may not fully cover the service area. The bandwidth must meet the minimum system availability metric, which is usually 99.9%.
Proper dimensioning is largely based on the benefits realised by pooling satellite bandwidth resources. When resources are shared, statistical probability can be used as an “oversubscription” model where creating a bandwidth pool maximises the number of fibre node restoral sites on the same satellite resources.
Locate Satellite Capacity
Satellites with footprints covering all or most restoral sites are preferred. This is key to a good design, since the parameters of the ground equipment will be selected to match the satellite footprints with the goal of OPEX reduction.
Spectrally Efficient Hardware
The best utilisation of satellite capacity requires efficient ground equipment. Proper design is performed using tools and hardware to maximise spectral efficiency.
Bandwidth optimisation techniques can be packet-based, using layer 2 or 3, such as IP header and payload compression, or the physical layer, with the transmission waveform. These techniques include ACM to reduce static link margin; advanced coding and modulation; carrier overlay (sometimes called carrier in carrier); and dynamic bandwidth management.
Automate Capacity Usage
Next, the operational criteria is established – automated or with a person in the decision path.
When a person is in the decision path, the event series typically involves the NOC personnel getting a call or alarm that a terrestrial link is down. The operator accesses the NMS, informs the network about the outage, and makes the hardware element changes to accommodate the outage sites with the most effective use of satellite capacity.
For automated outage recovery, the machine-to-machine connection detects/declares that a cable/fibre is down. The satellite backup network elements are activated without intervention by NOC personnel.

Mobile tracking and positioning system
A mobile tracking and positioning system includes a plurality of mobile
transmit and receive stations that track a mobile target which emits a
radio signal in response to the occurrence of a tracking effort initiation
event. The tracking stations have a GPS receiver or like means for
determining their position, a radio direction finder responsive to the
radio signal that determines the vector to the mobile target, a two-way
communications system and a computer. The mobile transmit and receive
stations exchange their position and direction to target information via
the two-way communications systems, enabling the stations to triangulate
the location of the target with their computers.

Coming mid-2010 there will be a new Wi-Fi standard that will allow any Wi-Fi gadget to connect wirelessly with each other without having to go through a wireless router. The best thing: It will only require a software update.
The new standard is called Wi-Fi Direct and—unlike Bluetooth—the technology will enjoy exactly the same speed and range as Wi-Fi. The Wi-Fi Alliance—which includes Intel, Microsoft, and Apple—says that it will automatically detect and hitch any device equipped with Wi-Fi within a 300 range, from computers to cameras to TVs to printers to anything in between. All peer-to-peer.
The Wi-Fi Alliance and everyone else—including myself—are pretty excited about this. So excited that they are planning a big advertising campaign to make people move to it. And since it will only require a downloadable software patch, you can expect the technology to become ubiquitous pretty fast.
Farewell, Bluetooth. It was not a pleasure to meet you. [Wi-Fi Alliance]

Motorola digital upgrade begins at Country Estate21st July 2021
Wirefr3 provided Stonor Estate with a Motorola two-way radio system (DP4400e and DP3441e). This solution centred around providing improved coverage across the Estate and Grounds. With the successful implementation of the radio system, we were invited to work with the team again to provide an improved Health and Safety solution. This solution focused on their Lone workers in remote locations carrying out tree cutting & maintenance.
The Estate wanted to ensure that these team members had a system that allowed them to notify & activate responders to any distress situations.
Lone worker function
We provided team members with a lone worker function on their two-way radios. The“Lone Worker” function provides a tone at regular intervals to which the lone worker needs to respond by pressing the PTT button. If the worker fails to respond within a pre-defined time, the radio will go into emergency mode. This sends an alert and user ID to all other users who facilitate an emergency response. The radio goes into hot-mic mode (open transmit) whereby the lone worker does not need to press the PTT to make a call. The worker can then talk into his radio and communicate with others if he is unable to utilise his hands or if he has fallen and unable to move.
Millions of workers within the UK are lone workers. Businesses must ensure that they have the correct safety procedures in place to protect them. Two-way radios provide an excellent solution for keeping workers connected and safe. In addition to the lone worker function, Wirefr3 can provide a “man down” function. This function will automatically send an emergency call when a worker is injured or falls unconscious.
To understand more on these functions, please contact Wirefr3 on 01442 864867.
