We offer four
Channels to choose from...
Shared Band 'U' (Channel 38)
UK Shared Band (Channel 70)
This UHF channel
is the most commonly used and spans the frequencies of 606 to 614MHz. You may manually tune a
Channel 38 radio mic system to any frequency within this
spectrum, and typically you would be able to use up to ten
systems safely (depending on the chosen system) each on a different frequency within that spectrum,
without interference between those systems. To use any of the
frequencies within the Channel 38 spectrum a low-cost licence is
UHF Channel 70
spans the frequencies of 863-865MHz. Only four frequencies
within this spectrum can be used legally: Ch70-1 on 863.125MHz; Ch70-2 on 863.625MHz; Ch70-3 on 864.500MHz; and Ch70-4 on 864.875MHz. All are
deregulated and free to use without a licence in the UK. With
most systems the frequency is fixed and you
must specify your choice of Ch70 frequency when ordering. Only
ATW-11/PF systems enable the user to select
the frequency manually.
Band [No licence
Unlike the two
UHF channels above, both of which are
specifically set aside for radio microphone
usage, Wi-Fi Band radio mic systems operate on
the same frequency as all other Wi-Fi devices,
namely by using the worldwide Wi-Fi frequency
which is 2.4GHz. Because of this they are
entirely licence free. Such systems can work
very well and sound very good indeed in
low-to-normal use Wi-Fi environments. However,
because they run on the same frequency as yours
and everyone else's Wi-Fi networks, we advise
caution if this type of system is intended for
use in a highly intensive Wi-Fi environment.
A fixed site
licence* (or Co-Ordinated Licence) enables you to reserve a set of
frequencies on the UHF band in your locality for
your use and your use alone. What this means is
that you buy the right to the sole use of one or
more frequencies in your area and they cannot
legally be used by anyone else in that area.
This is therefore the safest radio mic solution
of all and is perfect for fixed venues like
churches, schools and similar places in built-up
areas and anywhere there is a stronger

JArduino is a Java API to program Arduino boards.
I am a core contributor on this project together with Franck Fleurey. This project is composed of a Java API, a C firmware for the Arduino code, and all the code for the communication between Arduino nodes and Java nodes, as described in our MODELS 2011 paper. Most of the code is generated from ThingML models. Jan Ole Skotterud also contributed to JArduino, in particular with an advanced Java GUI to control the Arduino board. Francois Fouquet provided support for Ethernet communication in addition to the default serial communication.
JArduino is hosted on GitHub and available as open-source (L-GPL)


Imatest is integrated with the the MATLAB Image Acquisition toolbox and can acquire images from a multitude of analog frame grabbers. The following manufacturers provide frame grabbers that support a variety of standard and non-standard analog cameras including NTSC, PAL, RS-170, CCIR, and progressive scan. Please see vendor’s Web site for more details.
Frame grabbers will become part of the image processing pipeline, and therefore could either enhance or degrade the quality of the video signal. Not all frame grabbers will behave the same.

Introduction To Internet And associated Services
Internet: It is basically a network of tens of thousands of computer networks. Every network on these networks exchange information according to certain rules called protocols. Two Protocols used or working with the internet are Internet Protocol or IP and Transmission control protocol or TCP, usually known as TCP/IP. It enables the computer to talk the net's language. It also needs to have knowledge about your IP address and the server's address so as to convert the name of domain names into IP address and establish a connection. All the commonly used internet softwares like web browsers, newsreaders and mail clients often rely on this for conversing.

Here at Pointr, we specialize in working with Bluetooth® technologies and we find that many curious individuals ask us about what these really are, how they work, what they enable businesses, workplaces and more to do, and everything in between.So we have put together an article on everything you need to know about these fantastic devices.
It’s a long read, so grab a cup of tea and enjoy!
What is a beacon?
A beacon is a small device (approx 3cm x 5cm x 2cm) that constantly sends out radio signals to nearby smartphones and tablets, containing a small amount of data. The signal strength and time between each signal can be configured to give a desired coverage. Mobile apps can listen for the signals being broadcast and, when they hear a relevant signal, can trigger an action on your phone. Note that beacons only operate/talk in one direction (i.e. they can broadcast data but cannot read things off your phone). For the majority of current beacons, the data that they transmit is hard coded and doesn’t change frequently (i.e. set it once when configuring the beacon) and they rely on the device which is listening to do something intelligent with the data – in the future this is likely to start changing.
How do Bluetooth beacons work?
Beacons work using Bluetooth Low Energy (BLE) which is a version of the more common Bluetooth protocol, designed to use very little power and send less data – typically 1-20% of standard Bluetooth power and at 15-50% of the speed. They are often powered by batteries and as such the performance/battery life needs careful balancing to suit the application as the battery life can be anywhere from 1 month to 2-3 years (there are beacons using USB/mains power or solar panels so last much longer, and some beacons are coming out which are built into lights or light sockets). The beacons themselves are typically stuck to walls/ceilings or hidden in other objects since you can detect a beacon up to 70m away with no obstructions (depending on the power level).
How can beacon signal or range vary?
Whilst Beacons can have up to 70m range with no obstructions, this can drop significantly through walls which are made with metal or brick (though thin/stud walls have a much smaller effect).
In addition to the potential range of Bluetooth Low Energy, most protocols also operate with three ranges of distance: far, near and immediate – and a device can do something different at each range.
- Far – this is designed so that your device can do something when you can just about hear a beacon (i.e. walking past a store)
- Near – this is designed so your device can do something once you are in the same room as a beacon (i.e. walking into a store)
- Immediate – this is designed so your device can do something once you are virtually touching a beacon (i.e. touching an advert or checkout in a shop)
The signals also allows apps to recognize whether you are getting closer or further away, hence offer you a welcome/goodbye message as you shop, or even understand which parts of the shop you interacted with. Remember that this processing would have to be done by the app as a beacon only transmits data and cannot receive a signal from your phone – this information could however be transmitted back to the shop via a data/Wi-Fi connection.
Do beacons work with iPhones/Android/ Windows phones?
Yes all modern phones can support Bluetooth Low Energy but you have to turn on Bluetooth for anything to happen.
On iOS 7 and above (iPhone 4s and above, iPad 3rd/4th Gen/Mini/Air, iPod Touch 5th Gen and above), the phone can constantly scan for Bluetooth Low Energy devices and wake up relevant apps when they come within range of a relevant beacon (even if they are closed).
On Android devices there is no operating-system management of beacons and the apps must scan for Bluetooth Low Energy devices themselves. This means the apps must be running (can be in the background) all the time and hence use up more battery (not very much).
On Windows and Blackberry devices there are varying levels of compatibility but most modern phones over the last few years support Bluetooth Low Energy in a similar way to Android (e.g. Windows phones require the Lumia Cyan update).
Hey! Will Bluetooth Low Energy drain my battery?
In the same way as Bluetooth Low Energy uses 1-20% of the power of full Bluetooth in the beacon, it uses much less power on your phone. Leaving Bluetooth running on a Bluetooth Low Energy enabled phone should typically use 1-3% of a phone battery over the course of a full day – though if you are using standard Bluetooth at the same time (e.g. leaving Bluetooth headphones connected) then this can increase. We've got some more information on how Bluetooth can impact your smartphone battery here.
iBeacon vs BLE beacon - what's the difference?
Though the names suggest some major differences, there's actually very little difference between the definitions of ;iBeacon' and a BLE beacons. iBeacon technology is a protocol devised by Apple that aims to standardize the data broadcast by Bluetooth beacons. In other words, iBeacon is an Apple flavour, running on top of core Bluetooth Low Energy technology and beacons. Any Bluetooth beacon can be regarded as an iBeacon, if they advertise according to Apple’s standards. Currently Apple doesn’t make beacon hardware and expects beacon vendors to adopt their iBeacon requirements. There is a chance that Apple may release their own iBeacon hardware, and at this point a difference may emerge – some people say the iWatch is effectively an intelligent Bluetooth beacon (technically true) though not in the form most people would expect it.
Will all beacons work with my app?
All beacons transmit data in the same format and so are very interchangeable, though certain parts of the transmission are specific to certain manufacturers and hence the app should be configured for a particular beacon. In order for the app to respond as intended it needs to know exactly what beacon it is listening for and each manufacturer will have a set of tools available to help with this process. When conducting a Pointr installation, we always strive to use the same or complementary beacon types, and factor any existing hardware that the customer may already have in place too, such as particular access points. As the majority of beacons are similar and beam similar data, we prioritize things such as easy of installation and battery life (as this means fewer hardware refreshes are required over time).
What does Apple’s iBeacon technology do?
iBeacon lets iPhones/iPads/iPods constantly scan for nearby Bluetooth devices. When it identifies a device, like a beacon, it can wake up an app on the phone (even if the app is not running). Developers can make their apps responsive to iBeacon by using Apple’s Core Location APIs (application programming interfaces) in iOS. iBeacon can also be implemented into Passbook such that relevant messages/offers appear in your Passbook as you encounter specific beacons or Bluetooth devices (though an App needs to be installed which recognizes the detected beacon).
How does Bluetooth beacon tracking work?
Bluetooth beacons can send rudimentary data back to an app, which in turn, when corresponding with more than one beacon, can triangulate a user's position. Without an app interface, beacons are unable to make this calculation for themselves.
However, for a variety of reasons, even using multiple beacons isn't always effective for calculating a user's whereabouts in an indoor location. For example, while a group of BLE beacons may be able to pinpoint a user at one point, they would not be able to work out the direction that user was facing, and would struggle to keep up with a moving device. This is where Pointr's Deep Location® Platform comes in, with numerous unique technological calculations leveraged in order to bridge this gap and offer super accurate indoor positioning and indoor navigation.
So where can I get a beacon from?
There are currently a number of beacon manufacturers out there, all offering a slightly different range of features, flexibility, reliability and battery life. Estimote and Kontakt are some of the more popular beacon manufacturers and they offer a good SDK (software package) which allows you to configure and play around with the beacon, whilst also offering pretty decent battery life. You can get super small beacons, super long life beacons or waterproof/sturdy beacons from a quick search, you can even turn any Bluetooth Low Energy compatible phone into a beacon itself! Increasingly, the technology found in beacons is being replicated in other pieces of hardware, such as Wi-Fi access points or smart lighting - you might already have some beacon technology and not even realise it!
How much do beacons cost?
You can pick up a beacon for $15 or up to $35 depending on what features and battery life you want from it.
What businesses should invest in beacons?
There's no limit to what can be done with BLE beacons, and their inexpensive cost means that everyone from small retail stores through to huge locations like hospitals and airports can benefit enormously from investing in beacon technology.
At Pointr, we've worked with a large range of businesses and venues to make the most of beacon technology. We've helped retailers leverage indoor mapping and positional analytics to better understand where their customers are going and not going in their store. We've aided airlines and airports in improving their apps with indoor navigation to get their visitors to the correct gates quickly. We've empowered workplaces to keep their employees safe via indoor position contact tracking and improve efficiency by letting them know where they can meet easily and immediately.
What data do beacons send to phones?
Contrary to common understanding, beacons themselves transmit no meaningful data. Instead, they transmit short identifiers and it is the app that should make use of this information and do something useful. For example, an app can detect a short number broadcast by a beacon, then connect to internet to convert this number into a message, and trigger a push message on the phone. (Beacons can in theory send push messages without the internet but only of a few characters long). In short, beacons are dummy devices that advertise short identifiers, and it is the app that is responsible for doing something smart.
Technically speaking, beacons send a small stream of data containing a unique identifier and a small amount of customisable data. The identifier is what notifies an app to start listening and do something, while the data then gives some further information for processing. The identifier consists of three parts: a “UUID” which is typically the ID of the beacon vendor and a “Major” and “Minor” ID which are customisable and designed to signify different countries/regions/buildings/stores/rooms. The data is all transmitted unencrypted (by design) in a widely publicized format to ensure standardisation between manufacturers and platforms and as such can be spoofed. Apps need to understand this ‘feature’ to ensure nothing sensitive is transmitted through BLE and instead it should trigger another process which can be more secure.
What interference do Beacons cause?
Beacons do operate on the same frequency as some Wi-Fi signals (2.4GHz) and hence could cause interference, however they operate at lower power levels and transmit signals for very short periods of time – often for 1ms in a second (1000ms). As a result of this, even with many users simultaneously using Bluetooth, it is unlikely to have an effect on a Wi-Fi connection – there are loads of common household devices using this frequency band with much higher power levels and most of the time even they don’t have an effect. If the Wi-Fi connection is based on 5Ghz transmission then you will not get any interference at all.
What can I actually do with beacons?
This is where beacons get really interesting as you can do so many things with them, and the list keeps getting longer as people imagine new uses. Currently some of the working uses include:
- Indoor positioning and navigation
- Tracking of people or possessions
- Location based advertisem*nts or messages (for more on Bluetooth beacon advertising, click here)
- Security and automatic locking/unlocking of a computer
- Trigger requests for things like payments (note payments cannot be contained in BLE itself as it isn’t encrypted)
Where are Beacons used today?
Tens of implementations have been advertised in the last year, with the US leading the way in beacon integration. Marketing and loyalty drive the most common purposes at the moment, with some these examples:
- Macy’s is rolling out beacons across their stores in the US, for in-store marketing and loyalty.
- Major League Baseball are using beacons in their ballparks to offer fans the ability to check in, and get additional content on their phones.
- San Francisco airport is using beacons to help blind people navigate.
- The Swan Centre in the UK became the first shopping mall to use beacons, which allowed them to organize some in-store campaigns for its visitors.
- New Museum in NYC used beacons to give visitors a realistic minefield experience on their phones, where beacons became ‘virtual mines’.
- BeHere app allows students to register attendance automatically with their phones in their pockets.
- Google introduced ‘Physical Web’ which is also using BLE (not iBeacon), to enable users to interact with objects around them (e.g. A ZipCar car, a bus stop, vending machine or fridge at home) without an app by merely walking next to them.
What more's to come?
The last few years saw the inception of beacon applications which blend offline and online experiences for smartphone users. At Pointr, we believe we’re just seeing the beginning of a world where all your online behavior will blend in with your offline activities and many offline objects (bus stops, vending machines, cars, shopping malls, museums, car parks and department stores will all become smarter and we will be able to interact with them).
We foresee applications that range from straightforward loyalty/marketing ones (e.g. being greeted personally when you walk into your favourite store, and receiving tailored offers based on your online and offline shopping history) to really useful ones such as being able to track valuable assets (e.g. being notified immediately when you leave your wallet behind) or navigation inside huge indoor venues or even underground stations, mines, etc.


Power Banks are the simple solution to modern day’s biggest concern: The need to stay powered up and connected at all times. We can all agree that we feel slightly panicked when the “10% Battery Remaining” alert on any of our devices pops up. Nobody has the time to browse through tangled wires while also fighting to locate a power outlet. Power Banks are small and light, simple to use, and are easily accessible for such emergencies.
According to stats reported by PEW research, as of 2015 nearly two-thirds (64%) of U.S. adults own a smartphone. Of that 64%, 7% are considered “smartphone dependent” and rely on their mobile device for Internet service. Additionally, 46% of smartphone owners have admitted that their smart phone is something they “couldn’t live without.” Smartphones have become an indispensable part of our culture. People use them for everything from communicating with others via email, phone or text to taking and sending pictures / videos to obtaining and monitoring health information, online banking and keeping up to date on current events.
Smartphones, and their larger siblings including tablets, e-readers and laptops, are heavily relied on and the need to keep these devices charged is huge. This is where power banks come into play. Portable power banks are armed with a USB and a Micro USB connecting cable, allowing users to charge via a single power source. The electrical energy is then stored in the power bank for use when a phone, tablet, camera, GPS device, Go Pro, or any other tech device is running low on power
Don’t let their small, sleek, compact appearance fool you; power banks have some serious energy capacity! A power bank’s capacity is measured by how much energy it can store. This is also known as mAH (milli Ampere Hour). The higher the mAH, the longer the power bank will be able to charge a device. For instance, a phone with a battery of 1500 mAH can be charged once fully by a 1500 mAH Power Bank. A 5600 mAH Power Bank can charge a phone up to 3.5 times and can charge an iPad up to 40% battery life.
As the importance of Power Banks becomes more prevalent, companies are turning to these powerful devices for branding opportunities. Power banks come in all shapes and sizes and are fully customizable. You even have the ability to develop custom shapes and designs and choose exact PMS colors to match your brand’s personality and enhance visibility. Pair a power bank with another tech device like a Bluetooth speaker or headphones, and make a perfect corporate gift!

This research direction aims at creating deterministic interface between a quantum emitter (e.g., a semiconductor quantum dot) and light with the vision of realizing efficient single- and entangled-photon sources. To this end, we utilize designer nanophotonic structures that provide precise control over the local density of optical states (LDOS) for controlling the quantum light-matter interactions. We also optimize the semiconductor heterostructure design while epitaxially building a quantum dot to control the electronic properties of the emitter. This combination of photonic and electronic control has led to the generation of a record number of >100 identical single-photon from a single quantum dot with efficiencies that enable applications with quantum advantage*.
Photons are the best carriers for quantum information due to the simplicity in encoding and manipulating them. A key building block in realizing practical quantum technologies is an efficient and high-fidelity entangled photon source. While the quintessential example of an entangled state is a Bell pair, but the generation of multiphoton entangled states such as GHZ states and cluster states are essential for quantum networks, one-way quantum computing, and quantum simulation. In this project we develop this building block using semiconductor quantum dots.
This project is accelerated through the recently awarded Jumpstarting Tomorrow Seed Grant from OVPR in a quest to build an interdisciplinary team of researchers across Basic Sciences and Engineering for tackling the grand challenge of building a Quantum Simulator.

While the conventional approach for controlling light transport is by fabricating high-quality nanophotonic devices(e.g., photonic crystals, waveguides, cavities), scalable reconfigurability of light transport using such devices once fabricated poses severe challenges. In this project, we work towards integrating nanophotonic devices with wavefront shaping techniques. Reconfigurability is realized with the help of a spatial light modulator (SLM) that can precisely craft the wavefront of the light (classical as well as quantum) injected into a complex photonic device or an integrated circuit. This technique allows us to control many optical modes simultaneously, thereby leading to new opportunities in multimode quantum optics. A couple of examples include:
a) Shaping light to illuminate the dark heart of a photonic bandgap crystal. This will allow us to create nanophotonic cavities for creating quantum devices (e.g., single-photon switches, nonlinear gates) and address them optically.
b) Controlling multimode two-photon correlations and asymmetric quantum-secure communication schemes.


However, real-world IoT isn’t without its challenges. As more devices connect to the internet, IoT security will continue to pose a problem for hardware and software developers.

For the Internet of Things to reach mass-adoption in the real world a truly mature, security has to become a primary concern—because to this point, companies have been fairly lax on protecting IoT devices.
The Recent Reality Check for Internet of Things Security
If you think back to the morning of October 21, 2016, you might recall having trouble visiting some of the world’s largest websites and services—Twitter, Netflix, Spotify, Reddit, The New York Times, GitHub, and more.
Large-scale cyber attacks are frequent in the news now, but none have been able to affect so many premier companies all at once. And insecure IoT devices were the major cause.
For nearly 4 hours on October 21st, the managed domain name service (DNS) infrastructure at Dyn was hit by a distributed denial of service (DDoS) attack that flooded the servers with traffic to the point that people couldn’t connect to the services they use on a regular basis.
The reason this DDoS attack was so different from others is the fact that attackers used the Mirai botnet to execute the threat. The Mirai botnet scans for Telnet ports (an avenue for remote device connection that was created in 1969) and compromises devices by cycling through default usernames and passwords such as admin/admin.
This simple attack allowed hackers to take control of over 100,000 IoT devices (for example, security cameras and in-home DVR devices) that could flood DNS servers with traffic.
The large-scale attack on IoT devices showed the world what many hardware and software developers already know—that we’ve sacrificed some security for the sake of IoT adoption.
Balancing Security with Internet of Things Innovation
Unfortunately, attacks like the one involving the Mirai botnet will continue to happen. The reality is that we have to give up some security if we want to get IoT innovation out into the world.
If new products were built with every possible IoT security measure in the initial release, they would likely be too expensive for early adopters. The key is to embrace iterative development—get a minimum lovable product out into the world and as adoption grows, you can distribute the price of iterative security updates across more people.
This kind of iterative, agile development is essential for IoT innovation, especially if we want to overcome the obvious security challenges.
What Can We Do About Internet of Things Security?
The current IoT situation isn’t so different from where we were with email back in the late 1990s. Spam was overwhelming email servers to the point that people were calling for the death of email altogether.
Most enterprise organizations typically have 99.5% of their email traffic actually filtered as spam—and the remaining 0.5% is still a 50/50 split between unfiltered spam and actual email.
Spam was a serious problem, but we programmed our way out of it and email lives on. The same thing will happen for Internet of Things security.
The security issue we have to overcome with IoT is that these devices are built to be small, efficient, and send as little data as possible. The more security we build into an IoT device, the more inefficient and power-hungry it becomes.
We already have to gauge constraints, make devices as small as possible, and maximize battery life—these have typically come at the cost of security. However, we will fix these issues with technology:
- Blockchain: While blockchain has helped make transactional processes (real estate, art auctions, etc.) more secure, it is still too “chatty” for IoT. However, as it becomes more scalable and lightweight, the public keychain security method will become an integral piece of IoT.
- Verizon’s CAT-M Network: Verizon is working on introducing an IoT-specific network by the end of 2016. Competing with other types of IoT connectivity, the CAT-M network will enable less expensive modules, greater coverage both underground and in buildings, and longer battery life. While these benefits aren’t directly connected to security, the CAT-M network will make new security innovation possible.
- Intermediate IoT Gateways: The CAT-M network and other purpose-built IoT networks will make it easier to create purpose-built security gateways for IoT security. Trying to use a traditional firewall or gateway with today’s IoT connectivity options would require too much battery power to actually balance innovation with security. A dedicated security gateway could create a secure aggregation point for a set of specific IoT endpoints.
The Internet of Things isn’t just a passing fad. Universal connectivity of our everyday things is a reality that we must adapt to—and part of that means finding new, more efficient ways to implement security features.
While IoT security attacks are troublesome, they are growing pains that we’ve seen with other networked tech innovation in the past. The key is to understand the greater IoT landscape, how the technology will fit into your business, and what you need to do to prepare for its growth while making the right security decisions.

The adoption of industrial automation and plant automation has grown rapidly in various industries, from oil sands to pharmaceuticals, due to the numerous benefits it offers. Apart from productivity gains, industrial automation and control also improves safety, quality, and cost. Let’s discuss some of these benefits. We start with the advantages of industrial automation and control services for the power generation and refinery industries. Let’s look at these three benefits in more detail.
In the past, power generation and refineries relied on manual, analog equipment for supervisory control. These systems used timers and relays, but reconfiguring them was difficult. Then computers were developed for industrial automation. Telemetry was introduced to provide virtual communication. In the 1950s, SCADA was first used for refineries. It was the only viable solution for industrial plants. Today, SCADA systems are used throughout the power generation and refinery process.
The basic functions of a SCADA system are data acquisition, process supervision, and data analysis. A SCADA system needs to capture data from various elements of the plant, including valves, motors, and process states. It must also interface with other PLC integrators, instruments, and specific protocols to obtain this data. The data gathered by the Industrial conveyor system can help monitor the status of critical processes and monitor their performance.
Typically, SCADA systems use a supervisory computer to gather and store data on processes, send control commands to field-connected devices, and interface with operators. HMI software installed on operator workstations can be used for data collection and analysis. In more sophisticated SCADA systems, PLCs are used as RTUs and can communicate directly with remote equipment. This means that operators can access information from anywhere and control the process in real time.
The power of SCADA is the ability to monitor multiple assets at one time. The system consists of specialized hardware, computers, and networks that allow for data-driven decisions. The technology works with remote sensors and can also control actuators. Actuators can be anything from pneumatic cylinders to LEDs. With telemetry, SCADA can even predict the future. With this, plant operators can monitor and control a process without having to physically step on the controls.
SCADA controls allow users to monitor and control many different processes, including power generation and refinery processes. The software also allows operators and employees to view and analyze real-time data. Typically, SCADA is used in industries where human presence is impractical or unsafe, including oil and gas production, refineries, and power generation. The power generation and refinery industries are a perfect example of SCADA’s many uses.
As a critical component of power generation and refinery systems, SCADA controllers enable remote monitoring of critical processes, such as steam and gas turbines. SCADA controllers can also perform various functions related to energy management, drive control, and safety. The paper industry also relies heavily on SCADA systems, including enclosure systems, drying & pressing, and safety monitoring. The paper industry also relies on SCADA controllers throughout the entire supply chain.
As an industrial automation tool, SCADA controllers enable businesses to monitor and control complex processes and operations. They also enable them to monitor and control equipment from afar and automate tasks. The software collects data from sensors and monitors local environments for alarm conditions. SCADA systems can also monitor pipelines and offshore platforms, power generation & refinery plants, and petrochemical plants.
SCADA systems assist with the efficiency of different operations. For example, an operator could start a liquid transfer and then monitor its progress. The SCADA system would see this as one big function performed by the operator, and send a single control request to a local PLC that would do the transfer. SCADA systems are particularly useful for processes that can be monitored remotely and can reduce waste and improve efficiency.
SCADA data processing
The data processing for industrial automation and plant automation is a common method used to monitor a process or facility’s operations. It provides data at the production schedule and business network levels, including HMIs used by human operators. Managers can adjust production throughput, and administrators can track inventory and logistics. Each system is equipped with a collection of SCADA points managed by scada integrators , which record and log various inputs and outputs. Hard points, for example, measure the temperature of a process, and soft points are the results of a calculation or event. Operators can access this log to troubleshoot a system malfunction or identify potential problems.
The main goal of SCADA is to increase the efficiency of various operations. The technology enables businesses to study the results of measured conditions and then develop optimal responses that can be automatically implemented in the future. For example, when an employee detects a critical leak, the SCADA system can close a nearby valve based on the information. This automation will prevent costly mistakes caused by human error.
The terminology “SCADA” was first coined by the Bonneville Power Administration (BPA), a federal agency created in 1937 for the development of power facilities in the Pacific Northwest. It was later formalized by the ISA RP60.6 document, which defined control center terminology. Now, industrial enterprises utilize SCADA systems to monitor and control operations. A typical SCADA system uses a wide variety of sensors, actuators, and relays to monitor and control processes in a manufacturing facility.
SCADA began with a single mainframe computer, known as a monolithic system. As technology evolved, it became more scalable and capable of connecting to other similar systems. These systems were built on proprietary LAN protocols, which gave the vendor control over data transfer. The first generation of SCADA systems had no connectivity and were monolithic. But thanks to advances in communications technologies, these systems can now communicate with other systems and organizations.
SCADA data distribution
SCADA, or Supervisory Control and Data Acquisition, is a computer-based management system. This is used to monitor the operations of industrial processes. It provides an interface for thousands of sensors in wide regions. Its remote monitoring and data simulation capabilities allow companies to make better decisions, reduce operating costs, and improve efficiency. A SCADA system can be designed quickly, thanks to rapid application development capabilities. It also incorporates unit redundancy. This ensures that data is reliably distributed even when one unit fails.
Industrial automation and plant automation
In this , SCADA systems can divide into three main levels. Level one deals with inputs and outputs. These include controllers for field devices. Level two involves supervisory computers that manage the inputs from these field devices and update databases. At the centralized control hub, the data is visualized on a graphical user interface. Level three involves communications and production control.
SCADA data is distributed at the business network and production scheduling levels. Operators can monitor the production process using an HMI (human-machine interface). Administrators and managers can monitor logistics and inventory. Various points are monitored: hard points and soft ones. Hard points represent real-world values, while soft points are the results of calculations and events. The logging of data allows operators to troubleshoot problems quickly and prevent any further loss of product.
SCADA systems can be programmed to control field equipment. In most cases, SCADA systems can operate autonomously, but real-world complexity demands operator input. HMI software provides less control than PLC. SCADA systems can communicate with the host via modems to receive data. They can also send and receive information from remote sites. When the data is distributed, it is presented to human operators through a control panel.
Refineries are typically large, sprawling industrial complexes with extensive piping networks and multiple buildings. Many refineries have multiple levels and are surrounded by large storage tanks. Several piping networks run throughout the complex, and some refineries handle explosive gases. While there are a variety of different types of SCADA network deployments, all have common features. To ensure reliable operations and to maintain process integrity, refineries must implement comprehensive communications systems to monitor and control equipment.
SCADA systems for Industrial automation and control consists of several components, including remote terminal units (RTUs), to monitor and control process equipment. The primary component of a SCADA system is the RTU, which connects to sensors, meters, and actuators. RTUs are real-time programmable logic controllers that convert received signals from master units into instructions for the process equipment. They allow plant operators to monitor process conditions, change process parameters, and even monitor and control equipment from anywhere in the facility.
Power generation & refinery
The industry is an example of a SCADA network in action. Its purpose is to supervise production and prevent costly downtime. With this system in place, operators can monitor important machines in real time, minimizing costly maintenance and repair costs. Furthermore, SCADA systems also reduce personnel visits and minimize risk to employees. Furthermore, the SCADA network allows for better control and coordination of complex site operations, reducing operational costs and human errors.
The SCADA network can also monitor pipeline leaks, remotely open valves, and other assets, and execute pre-configured commands. The network devices are typically a Programmable Logic Controller (PLC) or Remote Terminal Unit (RTU). RTUs offer greater automation, such as the ability to monitor pipeline pressure and control valves when necessary. This automation helps power companies reduce costs and keep revenues at a high level.

International phone cards are created for the purpose of making international phone calls. In fact, they are designed for phone users who often make international phone calls. International phone cards offer multiple advantages. Card users save precious time and money. Occasionally individuals who use international phone cards receive free offers.
Not only are they easy to use, but international phone cards are inexpensive. A variety of services are provided by phone network companies through special access cards. Among them are internet access and SMS, local phone calls, STD calls, and international calls. Cards that are used to call internationally are, quite logically, called international phone cards. You can use this sort of phone card on a wired land-line, a wireless phone, or a mobile phone. ISD calls for fixed land-line phones were higher before international phone cards came into being. In addition to costing less, these phone cards also offer their users a favorable way to keep in touch with family or friends in other countries. Free gifts such as extra talk time, extended validity period and cash vouchers are featured in a good number of the international access cards.
You can activate an international phone card by inputting the 10 digit PIN number on a land-line phone, wireless phone, or a cell phone. Once the secret card number has been accepted, you can make international calls on the phone. The international phone cards are available in two versions: the prepaid and the postpaid. You can get a card that requires advance payment or one that you can pay for monthly. The majority of international access cards are good for a set period of time. Typical times are fifteen days, one to six months, or perhaps a year.
More people prefer the prepaid international phone cards than the kind that are paid later. If you have a prepaid plan, you can choose to buy a card that is just the right price for your budget. Postpaid phone cards work just like the prepaid cards. However, the plan usually does not keep track of the number of monthly international phone calls for the user. Monthly bills can be ridiculously high as a result. If you have a prepaid access card, you will be able to determine how much talk time you have left, and you will have a limit on how long your card will be valid. Once the amount on the card is depleted, the phone is locked. After all of the card conversation time is used, or if the date on the card expires, the phone customer can purchase a new card to continue calling.
The majority of mobile networking businesses give refillable international phone cards. When the card needs to be refilled, it can be recharged at any service outlet belonging to the network service provider. In this way, it is easy for a person or business to keep track of phone use and expense and keep it within a budget. The easiest prepaid international access cards to obtain are those offered online. Those seeking an international phone card should look at websites for various international phone card plans and choose the right plan based on their specific needs.
The principal benefit of online refilling of international phone cards is that holders of this kind of card can add credit to their card from the convenience of their computer via the internet. A person who is not completely satisfied with the phone services associated with his/her phone card is free to change it to another one at any time.


A radio frequency amplifier, or rf amplifers, is a tuned amplifier that helps to amplifies high-frequency signals found in radio communications. The rate of recurrence where optimum gain happens in an RF amplifier is made adjustable simply by changing the inductance or capacitance of the fine-tuned circuit. An rf amp can track over the required range of frequencies. The shunt capacitance enables high gain at radio frequencies since it negatively impacts the gain of the resistance-capacitance amplifier. The power gain of rf amplifiers is usually limited to high airwaves.
Types Of RF Amplifiers
There are many different types of rf amplifers categorized by several guidelines such as range, source current, supply voltage, gain, and result power at 1 dB compression (P1dB) as well as packaging types. The parametric filters will certainly enable you to improve your system based on the needed specifications.
RF Amplifiers For Potential Electronic Devices
You can get an array of RF Amplifiers from many manufacturers. Once you select if you want a CATV RF Amplifier, RF Low Sound Amp, RF Low Power Amplifier or the RF Power Amplifiers, it is possible to select from their technical characteristics and your search results will be narrowed to fit your specific RF amplifier needs. You’ll then be able to find the appropriate rf amplifers for your signal or IC, video amplifier, TV RF amplifier, TV amp, linear radio frequency amplifier, MOSFET RF amplifier or even the solid-state RF amp.
Applications For RF Amplifiers:
Amp applications consist of electromagnetic suitability (EMC) tests, defense parts, communications assessment as well as medical diagnostics. RF power amplifiers can be utilized in driving to some other high power resource and microwave heating system. They may also be used as traveling antenna, where the transmitter-receivers are utilized for the tone of voice and data marketing communications as well regarding climate change. Microwave or RF heating is utilized in industrial applications and also in microwaves.
Choosing The Best RF Amplifier:
When searching for the proper RF amplifier, you can filter the outcomes by the mandatory category. Once you select the RF amplifier category, you can narrow them down by numerous attributes: simply by the rate of recurrence range, supply current, source volts and product packaging type to mention just a few. It is possible to find the right rf amplifers for your RF amplifier circuit or IC, cable TV amplifier, radio amplifier, solid RF amplifier, and video amp or Television RF amplifier with these simple tips whenever you search online.
Are you searching for a good firm to buy electric supplies from? You will have to purchase the best supplies at good prices in order to make sure that they will work correctly. There are very a few businesses you could purchase the products from but not every one of them can fulfill your unique requirements. So make sure that the company that you work with will be able to provide you with the largest collection of products from different producers. Many companies usually do not have a good inventory since there are costs connected with this. Nevertheless, these companies are generally struggling to meet your precise requirements. A well-managed company will certainly do its best to be able to ensure that all the merchandise it has in stock for clients is of top quality. The organization that you buy your electrical products from should also be considered a very dependable one and to find one you need to conduct a good research. The items that you will get must be precisely the ones that have been promoted there. Furthermore, the items must have a guarantee period to ensure that you get the right support in case there is an issue.
