Automated Metering System
Burke-Divide Electric Cooperative uses automated meter infrastructure (AMI) and radio frequency (RF) technology to gather usage, voltage and other valuable information from our meters.
Radio Frequency (RF) Automated Meter System
Frequently Asked Questions
What are the benefits of a radio frequency, automated meter system?
The RF and AMI techologies provide Burke-Divide Electric Cooperative and its members with numerous benefits:
- Pinpoint the exact location of outages more quickly, meaning a faster response time.
- Collect hourly and daily meter readings to help members better understand their power consumption patterns.
- Collect voltage and other data across the system to better monitor power quality and system inefficiencies.
- Advanced system features that will allow for more trouble-shooting options for co-op employees from the office, increasing efficiency.
What information does my meter record?
Your meter records an electronic kWh reading, the date and time of energy usage, the overall peak demand of the electric account, if the meter has rotated backwards, and the number of times the meter has experienced a loss of power for any reason. In fact, the meter will record the date and time of light blinks and the length of the power outage.
How will the co-op read the meters?
The cooperative’s computer system will communicate with the meters through routers and collectors installed throughout the system. The meter reading is sent back to the co-op via secure radio frequency.
What day of the month will the meters be read?
All meters are read the 1st of each month.
What if my bill reports more kWh usage than normal or I think my meter is not working correctly?
Contact the co-op office right away to discuss your billing concerns.
Members are able to view hourly, daily, and monthly usage by using SmartHub, the cooperative’s online account management system.
Will my meter notify the co-op when the power goes out?
Yes. The meters will be able to record outages allowing the cooperative to verify whether the outage is either on the member’s side of the meter or the co-op's.
Are the meters secure?
Yes. The meter display is visible for members to be able to check their consumption. All other information and data stored in the meter is secure, and the meter is sealed.
Will someone other than the co-op be able to read the my meter?
It’s very unlikely but not impossible that some very sophisticated “bad actor” could access information from the cooperative’s automated metering system. Meter manufacturers are incorporating security features and encryption technology into their meters, as recommended by national security experts. Our goal is to upgrade our electric distribution system to make it safer, more secure, and more reliable. Your new digital meter is part of this effort. Once your new digital meter is installed, your cooperative will be able to tell if someone “tampers” with your meter because the meter will report any tampering attempts to the cooperative.
Are there any potential health impacts from a meter that can receive and send data?
No. Research conducted by the Electric Power Research Institute, the Utilities Telecom Council, and others has revealed no health impacts from digital meters. The radio frequencies emitted by digital meters falls well below the maximum recommended in federal guidelines. Contrary to some misconceptions, the new meters emit radio frequencies (RF) only when responding to a request for data from the co-op office – either once every fifteen minutes or once every hour for less than a second. Compare this activity to a laptop with a wireless connection, which is constantly sending and retrieving data. A digital meter equipped to send and receive data has an RF density hundreds of times less than the RF density of a cell phones – and the meters are installed on the outside of your house not next to your ear!
The FCC limit for RF exposure is 1 milliwatt per square centimeter (mW/cm2). At 20 inches in front of a meter, the average exposure to radio frequency signals is less than the background radio frequency signals naturally generated by the earth, and less than one-seven-thousandth of the safe exposure standard set by the Federal Communications Commission. Exposure to RF is significantly reduced by buildings. At one yard in front of the meter on a typical day, inside your home, your exposure is miniscule — more than 1.3 million times below the FCC standard.

Still Don’t Know How an IoT System Actually Works?
I don’t blame you. Although a quick Google search will turn up lots of articles and posts explaining what the Internet of Things is and its many potential benefits, it isn’t made clear how an IoT system actually works.
As the Director of Business Development at Leverege, I often find myself clarifying for those who are non-technical. So, as a non-technical person myself (at Brown I was a Philosophy major), here is a IoT explained in simple, non-technical terms.
A complete IoT system integrates four distinct components: sensors/devices, connectivity, data processing, and a user interface. Below I will briefly explain each component and what it does.
First, sensors or devices collect data from their environment. This could be as simple as a temperature reading or as complex as a full video feed.
I use “sensors/devices,” because multiple sensors can be bundled together or sensors can be part of a device that does more than just sense things. For example, your phone is a device that has multiple sensors (camera, accelerometer, GPS, etc), but your phone is not just a sensor.
However, whether it’s a standalone sensor or a full device, in this first step data is being collected from the environment by something.
Next, that data is sent to the cloud (what’s the cloud?), but it needs a way to get there!
The sensors/devices can be connected to the cloud through a variety of methods including: cellular, satellite, WiFi, Bluetooth, low-power wide-area networks (LPWAN), or connecting directly to the internet via ethernet.
Each option has tradeoffs between power consumption, range and bandwidth (here’s a simple explanation). Choosing which connectivity option is best comes down to the specific IoT application, but they all accomplish the same task: getting data to the cloud.
3) Data Processing
Once the data gets to the cloud, software performs some kind of processing on it.
This could be very simple, such as checking that the temperature reading is within an acceptable range. Or it could also be very complex, such as using computer vision on video to identify objects (such as intruders in your house).
But what happens when the temperature is too high or if there is an intruder in your house? That’s where the user comes in.
4) User Interface
Next, the information is made useful to the end-user in some way. This could be via an alert to the user (email, text, notification, etc). For example, a text alert when the temperature is too high in the company’s cold storage.
Also, a user might have an interface that allows them to proactively check in on the system. For example, a user might want to check the video feeds in their house via a phone app or a web browser.
However, it’s not always a one-way street. Depending on the IoT application, the user may also be able to perform an action and affect the system. For example, the user might remotely adjust the temperature in the cold storage via an app on their phone.
And some actions are performed automatically. Rather than waiting for you to adjust the temperature, the system could do it automatically via predefined rules. And rather than just call you to alert you of an intruder, the IoT system could also automatically notify relevant authorities.


SUITCEYES is among the 24 innovations from 200 submissions that has made it to the short list of the Innovation Radar Prize 2021. The next step towards winning the Innovation Radar Prize will be to participate in a public voting. This voting takes place on Dealflow.eu, where all 24 selected innovations will be introduced to the public.
The voting will start on the 23rd of September and end on the 29th.
The result of the voting will be considered by the jury during their selection of the 12 finalists who will present their innovation on the e-pitching event on the 21st of October, from 3:00 to 5:30 pm (CET time).
If SUITCEYES becomes a finalist, this will not be positive just for the project, it will also highlight deafblindness at a totally different level.Nasrine Olson, SUITCEYES Project Coordinator
The aim of the SUITCEYES project is to fundamentally improve the living situation of people with deafblindness by expanding their communication options via an intelligent piece of clothing. Equipped with a mini-computer, camera, echo sounder and vibration motors, the developed waistcoat picks up information from the environment and transmits it to the wearer via vibrations as “haptic communication”. Connected to a Tactile Board, which is based on a tablet with a special fabric cover, text messages and voice commands can also be translated into haptic messages. This promotes inclusion and accessibility and enables those affected to participate more in society.
The Innovation Radar is a European Commission initiative to identify high potential innovations and innovators in EU-funded research and innovation projects. Using intelligence gathered with the Innovation Radar method, the European Commission has, since 2015, been awarding the annual Innovation Radar Prize to the best EU-funded innovators.

Vehicle tracking systems come in many forms. Ultimately, the type of system you use will depend on what your business aims to achieve, the type of data that can be reported from a specific device, and the ease of the installation process. Currently, there are four main options available to businesses looking to install telematics to their vehicles. These are:
- Plug and play devices
- Hard-wired devices
- GPS tracking apps
- Telematics integrated cameras
Plug and play devices are self-installed by the user and powered by the vehicle’s on-board diagnostics (OBD) port or cigarette lighter. Because plug and play devices are fitted by the user, they usually require no installation fees; removing hundreds, if not thousands, of pounds when installing telematics to a larger fleet. It also reduces the amount of time your vehicles are off the road – most self-fit devices can be installed in under a minute. Having the ability to quickly remove the device and install it into other vehicles make the self-install option highly attractive to businesses that regularly change their vehicles or use vehicles on short-term leases. Historically, the self-install device was considered inferior to its hard-wired counterpart due to its lack of vehicle diagnostic features – however some vehicle tracking companies have now developed plug and play devices which report on vehicle and battery health.
However, self-install devices aren’t for everyone. In some vehicles, the OBD port is not easily accessible therefore the devices must be hard-wired to the vehicle. In other cases, some businesses such as those operating HGVs, plant and machinery may opt for hard-wired devices to lessen the likelihood of tampering or the removal of the unit by thieves. Hard-wired devices are also much easier to integrate with other fleet management solutions such as dashboard cameras or tachographs – although many involve installation and removal fees.
Many vehicle tracking companies now offer a mobile app in order to monitor the data transmitted from self-install and hard-wired units; however some businesses now offer GPS tracking apps which use the mobile device as the telematics unit. Mobile phones can easily be transferred between vehicles – although the data you can receive from them is limited because the phone is not directly connected to the vehicle.
More recently, we are starting to see vehicle tracking devices that are combined with dashboard cameras in a single compact unit. In contrast to traditional dash cams, these devices transmit video data to the cloud alongside the usual GPS, driver behaviour, vehicle health and collision data. Some of the most advanced telematics integrated cameras also integrate with tachographs, route optimisation, and route scheduling systems. These units are also beginning to provide Advanced Driving Assistance Systems (ADAS). ADAS features include audible alerts when a vehicle is travelling too close to the vehicle in front, veering from its lane or if the driver is micro-sleeping.


Fortaleza's technological hub occupies a prominent position. It is the second largest in the world. Currently, with 12 fiber optic submarine cables connected, it lags behind only Fujairah, in the United Arab Emirates, which has 13. The survey was conducted by the database specialist in the telecommunications market, Telegeography.
With the strong advance in recent years of large telecommunication companies, especially Angola Cables, Fortaleza has become a pole of concentration of submarine cables that connect the city with Africa, Europe and North America.
Operational, the Monet cables, which connect Boca Raton, Florida, to Fortaleza and Santos, and the SACS, which connects Angola to Ceará, are part of Angola Cables' more than US$300 million investment in the state. The operation of the multinational also involves a Data Center to be lauched in Praia do Futuro.
"More than consolidating the Angola Cables brand, Fortaleza actually ends up creating an attractive center for national and international players, because now there is a global connectivity of low latency and high capacity. This is why we are able to attract, for example, large international groups and companies, including those from Europe," so says the commercial leader of the company in Brazil, André Martins.
He highlights that the company has the cable with the lowest latency to the United States, besides a pioneering route to Africa. All passes through Fortaleza and, through the other cables, connects the city with other hubs in Europe.
Besides the presence in the technological market with the submarine cable connection, the Data Center installation is quite expected by the market and has already attracted the attention of large international companies, such as Google.
The commercial leader of Angola Cables tells that more than 70% of the Data Center's capacity has already been used even before launching. He reveals that a "large national media group" has closed a contract with the company to place its point of presence in Fortaleza.
"This Data Center is born very well connected to the world, because it already has connectivity with our submarine cables and, mainly, because it is a TIER III, with recognized international standards of quality, security, and reliability," he adds.
Regarding the presence in the Capital, Martins evaluates it as positive for the development of the city, because, according to the executive, Fortaleza was once a passage point, but now it has become a "presence point".
The development of the hub is also well regarded by the market. Emanuel Rodrigues, professor of the Computer Science Department at the Federal University of Ceará (UFC) and member of the Computer Networks, Software and Systems Engineering Group (GREat), analyzes that the growing rate of the hub in Fortaleza is higher than other points in Brazil.
"When there is a data center installed, and cables connected to Ceará, we become a point of attraction. Service, content and internet providers will be interested in installing themselves where there is a junction of information," says the specialist.

What is the difference: Telephone, PABX (Intercom) & VOIP (voice over internet protocol) ?
a�?Telephone is an instrument which reproduce sound at a distance through the help of electricity. It is one of the easiest and common used device of oral communication. It facilitates quick exchange of information through personal talk. There are two types of telephonic communication like external telephonic communication and internal telephonic communication. In the former communication an employee of the organization talks with another outside the organizational building. In the later communication an employee talks with another within the organization. Because of this nature of telephonic communication, it has been told that it is quickest and convenient means of external and internal communication. There are three types of telephone connections like direct exchange line, private branch exchange and intercom.
Intercom system of communication has become very popular in our country. It is used to supplement private branch exchange system and operates without an exchange. As this system is not connected with telephone exchange, no permission is needed from the post and telegraph department for the use of intercom service. Multicore cables and telephone receivers are used in this system. Push buttons are used in the receiver set. By putting the button instant connection is obtained with any one of the circuit. If he wants to talk a number of persons at a time he can push the conference key available in the intercom. Today computerized intercom system are developed.a�? ARKUPAL ACHARYA
The PABX is very commonly used in businesses and hotels, as communication is very important. The receptionist no longer has to walk to the bosses office to inform him about a visitor, she can easily lift her phone and talk to the boss at absolutely no additional fees. Research has shown that workers spend 30% of their productive hours moving from one internal office to the other to share information and chat. This can significantly be reduced with the use of the PBX solution for office.
The traditional PBX system is the analogue PBX which makes use of a single pair or double pair telephone cables. With the traditional system, the brainwork (processing) is done solely at the central console and the various phones connected directly to a dedicated port in the PABX console. The traditional PBX system currently faces some challenges in todays technological world:
Auto Attendant, Call Recording and Voicemail: to configure these features on an analogue PABX, extra boxes are required for each of them and the settings becomes very cumbersome.
VoIP however is running your voice communications over the same LAN or WAN network without having to incur an extra cost for cabling. It is very easy to set up and requires minimum maintenance over the period. VoIP is an advancement in the world of telephony because of its integrability into other platforms, i.e. you can easily use your computer as the telephone over the same network or you can fuse the VoIP into your Video Conferencing needs. You can have your calls rerouted to your cell phone automatically ones you are not seated in the office. Your Voicemail, Auto attendant, etc are all just settings on the Sever which doesna��t require an extra console at a cost. Each phone on the VoIP network is a a�?minicomputera�? and has some processing power that makes the work of the administrator very easy.

Your home is getting smarter, and that’s a good thing. You can control your heating from your phone when you’re working late. You can stream music through rooms that used to be quiet. With a smart lock on the front door, you can let your neighbor in while you’re at work.
It seems like there’s a new device every day, and it’s getting harder to keep track of them all. Some sensors know when your home is too hot or too cold. You can control your lights with a voice command, and you can unlock the door for friends using your phone.
But have you ever thought about how everything seems to be working in harmony? How do smart homes work?
The concept of smart technology revolves around the Internet of Things (IoT). The IoT is simply a series of devices connected to the internet. Using cloud computing, these devices can interconnect and share data.
Smart technology also makes use of artificial intelligence. With the right system, your home can analyze data and learn what you like. For instance, if it’s 10 PM, your smart thermostat might realize that you’re not at home and turn down the heat to save on energy costs.
Common Problems with Smart Homes
Smart homes are supposed to make life easier for homeowners with busy lifestyles. But they don’t mean you won’t encounter problems anymore. As a homeowner, you need to watch out for the following:
1. Smart Devices Cannot Connect to the Network
Sometimes smart devices cannot connect to the internet. This means that you might not be able to control them remotely or receive data about their use.
One common cause for this is a weak connection between your router and the device in question. Make sure there isn’t anything blocking the path, such as thick walls or furniture.
If you didn’t connect your router to your modem correctly, you’d have the same problem. The connection between these two is critical for connecting everything else.
Suppose your smart devices are connected but are not working correctly. In that case, there’s a compatibility issue with the device or its operating system. You may need to get in touch with customer service.
2. Your Automatic Garage Doors Won’t Open
Automatic garage door openers will allow you to control your gate from a smartphone. However, if the Wi-Fi signal is weak inside the garage, the device might not connect to its cloud server.
If your garage door isn’t working on its own, check with the manufacturer about integrating it with your existing opener. You can also call experts for garage panel door repairs and check if some panels are causing your system to malfunction. Sometimes the reason isn’t internet-related but due to issues with one or some parts of the automatic garage. These include tracks, rollers, springs, and more.
3. It Will Not Communicate with Other Devices
If all smart devices can communicate but do not work, the problem could be how you installed them.
You need to assign each device a different IP address to ensure that they’ll work correctly individually. That means that no two devices should have the same number. Suppose you enter an incorrect number or forget what code was assigned. In that case, you can disrupt communication between all of your devices.
4. Lights Turn On Randomly or Won’t Turn Off
Lighting is essential for home safety, but turning them on and off manually can take away from convenience. That’s where smart lighting comes in. However, if the device turns itself on without any command, there’s a problem with the system.
One reason for this is smart lights couldn’t switch off while you were away. If one of your devices goes offline while you’re out, it might remain on when you get home and no longer respond to commands. It will also use up energy even if it’s not needed.
These problems can occur because of compatibility issues between your devices. This is common with smart lighting because there are many types of bulbs and switches. Some don’t work properly when paired with competing brands.
Miscellaneous Problems and Fixes
You also need to be wary of using different networks for different gadgets, such as wireless routers and Bluetooth connectivity. Using too many connections can overload your wireless router.
You can solve these problems by using a smart hub, which acts as the central control panel for all of your devices. An easy DIY solution is setting up a WeMo Switch with Alexa. It will allow you to turn off anything that’s connected to it without having to get up from the couch or step out of bed.
Smart devices in smart homes are the way of the future. But that doesn’t mean that it’s foolproof. You’ll still need to keep an eye on the things discussed in this article so you can keep your systems working at optimum levels.

Since it’s introduction in september 1998, Wi-Fi has gained popularity due to it’s capability of communicating with multiple computer devices over a specific area location.
Wi-Fi definition although has been incognito and clueless in the minds of many despite it’s widespread use. A research was done and it was found out that out of 50 users of Wi-Fi only 4 know the meaning of the certified network.
Wi-Fi is a technology for wireless local area networking with devices based on the IEEE 802.1b standards. It was a play on HIFI which meant High Fidelity.
Fidelity means something that you don’t know is there but it’s actually there, like trust or faith. Wireless Fidelity , a technology used to certify the interoperability of wireless computer network devices is what we call Wi-Fi.

THE LONDON OLYMPICS area is set to get free Wi-Fi, thanks to a deal being done between British Telecom and 2012 organisers.
The London Olympic Games Organising Committee (LOGOC) and BT are “in negotiations about implementing a possible public service Wi-Fi at the Olympic Games,” BT vice-president Stuart Hill told Computing magazine.
“LOGOC wants this to happen, as do the mobile operators.”
Mobile phone companies are concerned that their 3G networks won’t be able to cope with the traffic likely to flow at the site, especially as loads of traffic these days is made up of images and videos, which use up more capacity than texts and speech.
Hill estimated that 6GB of information would be carried every second while the Olympics was running, about the same as downloading the whole of Wikipedia every five seconds, calculates Computing.
In a separate development, BSkyB’s Wi-Fi section, The Cloud, yesterday launched a free Wi-Fi service – for 15 minutes a day – in the City of London.
In May last year, Boris Johnson pledged that the whole of London would get free Wi-Fi in time for the Olympics.
But since then little has been heard about the London Mayor’s promise to hook up “every lampost and every bus stop” for Wi-Fi access.

The Perks as well as Disadvantages of IP Phones
Voice over IP phones are significantly ending up being the choice of service people, exclusive people, as well as even federal governments that are looking to cut their expenses and also boost their communication performance. An IP phone or VoIP telephone utilizes digital voice over internet procedure technology for putting and afterwards transmitting telephone call using an IP network, like the Internet. The advantages of using this sort of phone include: These type of phones usually have a much better array than regular analog telephones due to the fact that they use digital technology as well as for this reason can cover a larger area with less obstructions. Voice over IP phones can additionally function well in position where regular telephones are not convenient, such as long distances. A number of companies offer IP phones that have VoIP functions, including Microsoft Exchange as well as Lotus Notes. A crucial function of IP phones is their call top quality. Digital phone lines are much more reliable than regular telephone lines. Due to the fact that there is no digital signal involved, these phones make better sound than regular ones. These functions make the calling experience of IP phones far more pleasurable one. On top of that, nevertheless, there are various other downsides to utilizing these kinds of phones. The most effective way to enjoy the advantages of VoIP solutions is to have them integrated into your company’s existing telephone system. In this manner, the signals from the IP phones will certainly be exchanged the analog signals utilized in the workplace network. Having your IP solution incorporated with your company’s system will also enable you to have much higher control over which website traffic experiences your workplace network as well as which ones don’t. You can, for instance, block some calls made to your workplace phone by your staff members. There are particular downsides to making use of IP phones. One of these negative aspects is that they typically have a much shorter variety than do traditional analog phones. They can go just as for the signal that is currently offered. You can still delight in good quality phone calls, however. Digital phones use a much wider variety and also they are a lot more affordable than standard analog phones. If you are interested in using IP services, you should explore electronic phone systems rather. With an IP system, you will obtain the sort of features that IP phones need, yet you will be able to go also farther and also attach to numerous numbers utilizing VoIP. Digital phones call for extremely little maintenance and they are not impacted by any type of kind of signal disturbance. You can have all the functions of a VoIP system without paying a great deal of money for it.


WhatsApp is one of the most widely used instant messaging apps despite lacking many features. For example, Telegram allows you to use the same account on multiple devices, but unfortunately, this was not possible with WhatsApp – until now. You can now officially use the same WhatsApp account on two phones.
The Connected Devices feature on WhatsApp was introduced last year, but you can only use it on your computer or web browser. However, WhatsApp has released a new update that allows you to link a smartphone to your account. If you’ve always wanted to use WhatsApp on two different devices with the same phone number, now it’s possible. Here’s how it works.
WhatsApp introduced a feature called Connected Devices to replace the old WhatsApp Web functionality. This feature allows you to connect up to 4 devices to your WhatsApp account. Once connected, you can use WhatsApp on these devices regardless of your smartphone.
However, until now, you can only use the connected devices feature through a browser on a computer or another phone. This is not the best solution for those who want to use the same WhatsApp number on two phones. Thanks to a recent update to the app, this is no longer an issue.
Needless to say, you will need 2 phones to do this. If both are with you, follow these steps.
Step 1: Install WhatsApp on your primary phone and login. If you are already using WhatsApp on your mobile then skip this step.
Step 2: Install WhatsApp from Play Store on your secondary device. If you already have WhatsApp installed on this phone, uninstall it and reinstall it.
Step 4: Tap on ‘Agree and Continue’.
Step 5: When prompted to enter your phone number, tap the three dots in the top right corner of your screen. Then, tap on ‘Pair a device’.
Now you will see the QR code displayed on your phone screen. Switch to your primary device to scan this code.
Step 6: Open WhatsApp on your primary device. Tap the three-dot menu in the top right corner.
Step 7: Select connected devices. Now go to ‘Pair Device’.
Step 8: The QR code scanner will now appear on your screen. Scan the QR code on your secondary phone.
You are now logged into WhatsApp with the same account on both your devices.

As we move toward the end of our discussion of car audio electrical theory, we need to talk about capacitance and inductance and how the characteristics of those phenomena interact with AC and DC signals. There’s no doubt that these are advanced concepts, but even a basic understanding of how capacitors and inductors work is fundamental to a thorough understanding of mobile electronics systems.
What Is a Capacitor?
A capacitor is a two-terminal electronic component that stores energy. Capacitors are made of two metallic plates that are separated by an electrical insulator. When we apply a voltage to one terminal of the capacitor, the electrons on one plate will impose a force on the opposite plate to create an opposite charge. The result is that the plates have equal and opposite charges and thus, maintain an electric field. Because the plates in a capacitor are very close together, they can store a large amount of energy for their overall size.
Capacitors are quantified in units of farads. A farad is defined as one coulomb of charge on each plate, resulting in a voltage of one volt across the terminals.
Capacitors in DC Circuits
Capacitors are, at their most basic function, a device that stores a microscopic magnetic field between its plates. When we apply a DC voltage to a discharged capacitor, it appears as a short circuit for an instant as the magnetic and electric fields start to form between its plates. As the capacitor starts to store energy, it increases in effective resistance, and the amount of current flowing through the device is reduced. Once the capacitor has equalized with the supply voltage, almost no current passes through the device.
When we remove the supply voltage from a capacitor, it will attempt to maintain the voltage across the terminals. It is this characteristic that makes capacitors an ideal solution to reduce variations in voltage. Capacitors resist changes in voltage.
Inside the amplifiers in our car audio systems, capacitors are used to store large amounts of energy at the rail voltage. When there is a sudden demand for current that exceeds the capability of the power supply, the capacitors will release energy to maintain their initial voltage. This characteristic helps to stabilize the voltage of the amp during dynamic transients. This same concept applies to “stiffening capacitors” used on the 12V feed to your amplifier. When implemented using high-quality components, the addition of a large capacitor can help to provide transient current to the amp.
The Capacitor in AC circuits
In alternating current circuits, capacitors take on an interesting phenomenon of “virtual resistance.” As we know, capacitors don’t like to change voltage, yet an AC signal is one that is defined as ever-changing. Depending on the relationship between the capacitor value and the frequency of the AC signal, some amount of the current is allowed to pass through the cap.
If we attempt to measure the resistance of a capacitor with a conventional multimeter, we’ll find it shows an extremely high value. For AC signals, we use the formula Xc = 1 / (2 x 3.1416 x F x C) to calculate the effective resistance, where F is the frequency of the signal and the C is the value of the capacitor in farads. Because this resistance is not present in DC signals, we call it capacitive reactance.
If we wanted to create a simple filter circuit to limit the amount of low-frequency signal going to a speaker, we could wire a non-polarized capacitor in series with the speaker. To calculate the frequency at which the cap starts to reduce bass going to the speaker, we can rearrange the above equation to F = 1 / (2 x 3.1416 x R x C), where R is the same value as the speaker resistance. For a four-ohm speaker and a capacitor with a value of 200 uF (microfarads), we get a frequency of 198.9 Hz. At this frequency, the capacitor appears to have the same reactance as the speaker, and the signal that is going to the speaker is reduced by 50 percent. Because capacitance is inversely proportional to frequency, the impedance of the capacitor increases as frequency decreases. At 99 Hz, the reactance is 8 ohms, at 50 Hz, it’s 16 ohms, and so on. This phenomenon simultaneously reduces the current supplied by the amplifier and acts as a voltage divider between the cap and the speaker.
A capacitor in series with a speaker is known as a first-order high-pass filter. It reduces the output of the speaker at a rate of -6dB per octave as you move away from the crossover frequency as defined above. Capacitors are suitable as filters for midrange and high-frequency drivers in passive designs and as protection devices for tweeters in active designs.
What Is an Inductor?
In the simplest of terms, an inductor is a coil of wire that creates a magnetic field based on the amount of current flowing through it. Many inductors feature iron cores to increase the intensity of the magnetic field. Where a capacitor resists changes in voltage, an inductor resists changes in current flow. We know from our previous article on magnetism that current flowing through a conductor creates a magnetic field around that conductor. If we wrap the conductor in a loop, the proximity of the loops to one another intensifies the magnetic field.
Also from our previous article, we also know that a magnetic field can impose a voltage on a conductor. If the current in an inductor tries to change, the magnetic field attempts to create a voltage across the device to maintain the current flow.
A good analogy for an inductor is a flywheel on a motor. Once you have established a specific rotational speed, it takes a large amount of work to increase or decrease its speed. Inductors work the same way with current. They resist changes in current flow. Inductors are rated using the unit henry (H). A henry is defined as the opposition to electrical current flow through a device that results in one volt of electromotive force to appear across the terminals.
Inductors in Electrical Circuits
In most applications, we don’t want inductors in a 12V DC circuit because they resist changes in current flow. For a variable load such as an amplifier, a large amount of inductance in the supply wiring would result in an unstable supply voltage as the current requirements change.
There are some cases where inductors are used in combination with a capacitor to act as a noise filter.
In an AC circuit, inductors allow low-frequency signals to pass through the device with little to no effect. If we wire an inductor in series with a speaker, it acts as a high-pass filter. Unlike a capacitor, in a DC circuit, an inductor appears as a short circuit with very little resistance. To an AC signal, we can calculate the reactive inductance of a capacitor using the equation Xl = 1 x 3.1416 x F x L, where F is frequency and L is inductance in henries.
If we want to use an inductor as a high-pass filter, we can determine the effective crossover point by swapping the Xl for the resistance of the speaker. In this example, we’ll use an inductor with a value of 6 mH (millihenries) and a speaker with a nominal impedance of 4 ohms. There, the -3dB point of the filter circuit would be F = 4 / (2 x 3.1416 x 0.006), or 106.1 Hz. This value of inductor would make a good low-pass filter for a woofer. Just as with a capacitor in series with a speaker, an inductor acts as a first-order filter and reduces output at a rate of -12dB per octave as frequency increases from the crossover point.
Other Cases of Inductance and Capacitance
Anytime two conductors are parallel to each other and in close proximity, there will some level of capacitance. Many overly exuberant enthusiasts talk about capacitance in interconnect cables. While this is a factor, the microscopic changes (if indeed any are perceptible) can be compensated for during the tuning process of the system. When it comes to buying high-quality interconnects, noise rejection and overall design durability should be your top goals.
The voice coil winding in the speakers we use has a certain amount of inductance. This characteristic reduces high-frequency output by reducing current flow at high frequencies. Because speakers are dynamic, their parameters change as the speaker cone moves. In the same way that having an iron core in an inductor increases inductance as compared to an air-core design, the inductance of a speaker voice coil increases when the cone assembly moves rearward into the basket. The T-yoke in the center of the speaker increases the strength of the magnetic field created by the current in the voice coil. Likewise, as the speaker moves forward, the inductance decreases. These position-based inductance distortions can cause a high-frequency warbling effect that can be detrimental to the reproduction of your music. One solution is to implement an under-hung voice coil design where the gap is taller than the coil winding. The drawback to this design is that the voice coil is often small and lacks power handling. Another option is to include a copper pole piece cap to reduce the magnetic field and minimize distortion. A copper cap is an expensive option but offers excellent performance benefits.

The idea is to have two antennas, four rigs, and be able to switch any rig to either antenna, at the same time connecting the other antenna to one of the other rigs.
Obviously it must not be possible to have two rigs connected to each other, nor to have both antennas connected to one rig at the same time.
What it will also be able to do is to switch a rig between two antennas with one switch action, or one antenna between two rigs with one switch action.
I want to use it on 2m, but not certain it the relays will be OK.
New inexpensive relays have short internal paths compared to those of 20 years ago, I decided to try it, and if it didn’t work, just to use it on HF.
Circuit diagram at the very bottom of the page
Well, it works!
In practical terms, if I transmit 45W through the first port on 145.0, and connect another radio to the second (adjacent) port, that is not switched through to an antenna, I get an S3 signal if it is tuned t 145.5, and an S7 signal on 145.00125.
The change to SWR measured at the rig is 1.05:1 going to just under 1.1:1
Much better than I had expected, there is a lot of wire in it
The toggle switches select which antenna that radio will connect to, and the rotary switches select which radio that antenna will connect to.
The toggle switch switches the ground to the relays, and the rotary switches the positive to the relays

Virtual Private Network, or VPNs, refers to a secured internet connection that helps encrypt and protect your online identity and activities when accessing the internet through a public network.
Since using an unsecured network connection can expose you to anyone looking to steal your personal information, a VPN can be an invaluable tool to protect yourself and the networks you use to work and play.
VPN uses have become more pronounced in the last two years. As many businesses continue letting their employees work from home, the importance of maintaining network security remains more important than ever.
Because many companies have been making more use of the cloud to archive work data, VPNs provide a safe and secure way for employees to maintain their own levels of personal work comfort without compromising the integrity of their employer’s networks.
Having a work computer does not mean you have a secure connection to the office networks. Just because you can still access some of the programs you use every day from home doesn’t mean you automatically get access to the company’s server. And if you’re going to work remotely, you need access to that network.
Don’t confuse a cloud VPN with a standard VPN, though. The standard VPN requires the program’s infrastructure on your computer or a mobile device. In a sense, a standard VPN functions like any other phone application; unless you’ve got it on your device, you can’t use it.
But a cloud VPN allows the user to create between user devices and the virtual private cloud, or VPC, set up for your home office. Think of it like a virtual string connected between all devices in your office, and every piece of information that runs along that string has been encrypted for maximum protection.
There are two main categories of cloud VPNs presently available: the client cloud, and the network cloud.
This type of cloud VPN works best for creating information roadways between the cloud network and the company’s home network.
Client Cloud VPN (Remote Access)
This type allows IP addresses from outside the network to make a connection to the company’s network.
The information shared on a cloud VPN works on the same principle as an encoded message: the information from one user gets encrypted before traveling along the connection line to its destination, as which point the information gets decrypted for anyone with network access to that information.
Additionally, certain cloud VPN offerings allow the users to connect with a secure connection, providing another line of data security that a regular internet connection cannot supply.
Finally, the remote access previously mentioned offers peace of mind for any company that has employees remotely, either at home or out in the field. The cloud VPN’s ability to let its users adapt to new environments and working situations without compromising security or user integrity makes VPN a valuable tool.

The "XLR" connector is also known as a "3-pin" because it has, well, three pins. The third wire gives an XLR several advantages.
1) You can run an XLR cable for hundreds of feet without any significant loss of signal. Conversely, two-wire cables are limited to something under 50 feet.
2) XLR's are less likely to pick up outside interference than two-wire cables.
3) XLR cables have a little lock built in so they won't accidentally pull apart.
Because of these advantages, all high-end television production uses XLR cables for audio. The problem with XLR connectors is that they are big and bulky. Smaller gear needed a more compact solution--and thus the increasing use of the RCA and other connectors.


With 99 percent participation in electronic medical record keeping, the Netherlands leads the world in medical practices that use electronic records. While the development and use of Bring Your Own Device, or BYOD, programs can help health care providers save money, it requires careful planning in order to comply with the 1996 HIPAA standards. In order to do so, finding a secure instant messaging program can be a good idea. Secure text messaging can help practices protect the vital data of both themselves and their patients. If they use secure instant messaging, they can help both employees and patients feel comfortable sharing information in that way, which can lead to increased efficiency.
Health 2.0 can include concepts like telemedicine, electronic medical records, mobile health applications, and more. In order to make sure that these practices are kept safe, medical centers will want to use secure instant messaging and other techniques. HIPAA was enacted by the U.S. Congress and signed by President Bill Clinton in 1996. In order to make sure those conditions are met, practices will want to use all of the security resources available to them, including secure instant messaging technology.
Medicaid is just one area where electronic applications like secure instant messaging can be both helpful and cost efficient. The Medicaid process can be streamlines by filling out one form electronically and having it automatically routed to the most appropriate programs with minimal paperwork and interaction. The ability to make the sharing of information more streamlined and efficient, in addition to the added security, is one of the greatest benefits available to practices who use secure instant messaging and other electronic applications.


Why You Should Consider Cell Phone Tower Leasing
Cell phone has become a basic tool in the modern world being the basic tool of communication to people at a distant. It is essential to note that any cell phone tends to rely on signal making it necessary to ensure a cell phone tower. It would be essential to note that you can only be in a position to get reached or even reach to others through mobile phone where there is a good network. In that case, the cell phone service providers would need to consider always providing the subscribers with a good network. It is due to the purposes of the provision of a good network that the cell phone service providers tend to come in to ensure cell phone tower leasing.
Most cell phone services providers need to have cell phone towers strategically and hence the need to lease land where they can install the towers. It would be essential for one to remember that leasing tends to be legal and tends to involve an agreement between the parties before getting into the deal.
One would need to note that there are various benefits related to the cell phone tower leasing. The number one benefit of cell phone tower leasing is that one tends to benefit with some good money from his or her piece of land. As a matter of facts, the cell phone tower leasing tends to be more profitable when compared to most other types of leasing. The service provider tends to get its money back by making sure that communication remains constant. By keeping the communication going, the mobile service provider tends to get its money back.
Any cell phone user tends must subscribe to a mobile service provider to be connected to the network allowing him or her to reach other people. For one to reach other people, he or she would need to use money. As a result, the tower tends to allow people in a specific location to be in a position to reach other people and at the same time make the people in the same region be reachable.
After the installation of the tower, it tends to be possible for the mobile users in the location to reach their contacts within the reach of the network and also tends to be reachable. The people living in the area in question becomes accessible and also tends to have very easy time communicating. One as a landowner would need to know whether the land is genuine just to be safe. One would, as a result, need to consider leasing his or her land to a cell phone company as he or she would enjoy benefits for years.


Wireless communication otherwise known as ‘over the air’ is the transfer of information between two or more points that are not connected by an electrical conductor.

Data acquisition performance for deep space communications in solar probe plus frontier radio
|Author||Kufahl, Katelyn; Adams, Norman; Kirschner, William;|

|Abstract||Radio receivers for deep space telecommunications require tracking loops that are robust in low signal-to-noise ratio conditions for not only carrier tracking, but also subcarrier tracking and bit synchronization. However, the loop band-widths must not be too narrow so as to accommodate Doppler dynamics, oscillator drift, and requirements for expedient and reliable data acquisition. The present work describes the data acquisition performance of Frontier Radio for the NASA Solar Probe Plus mission. The data acquisition time is a statistical quantity, as it depends on the frequency and phase state of the uplink waveform which is random with respect to the receiver. In order to rigorously characterize the performance and determine a nominal worst-case acquisition time, an automated test procedure was developed to execute a large number of acquisition trials. By architecting an automated procedure for the remote control of instruments, including timing control and uplink signal phase randomization, acquisition time measurements were more precise, more accurate, more consistent between trials, and greater in number than previous attempts. Thus, through this procedure we are able to estimate the upper bound on acquisition time to the 98th percentile with high confidence. Worst-case acquisition time occurs when the uplink data phase is 180° out of phase with the receiver bit clock; to mitigate this effect a circuit has been developed to detect the 180° condition and induce a phase step in the receiver bit clock with intent to align the two phases. We confirmed that the phase injection feature improves the worst-case acquisition time by a statistically significant margin: 62% to 85% acquisition time decrease in the 90th percentile acquisition time as a function of uplink data rate, with a 98% confidence interval. We describe the acquisition time results at all supported uplink data rates, over a range of signal power and Doppler offset conditions. Also described is the automated procedure, its contributions to the experimental soundness of the measurement compared to previous methods, and an estimate for its reduction of labor costs over time.|

The National Communications Authority under the Ministry of Communications has launched the Digital Audio Broadcasting (DAB) in Ghana.
In the trial phase, up to eighteen (18) existing FM stations in Accra and Kumasi will share one frequency channel out of VHF band III and transmitter in the two cities.
DAB is a digital radio standard for broadcasting digital audio radio services in many countries around the world. It is expected to provide good quality audio and support the provision of value-added services and spectrum efficiency.
The launch, according to Director General of the NCA, Joe Anokye will “position Ghana as the first country in west Africa and the fourth in Africa to deploy DAB.”
The initiative is to deal with the incessant demand for FM frequency authorizations in the face of severe frequency constraints through technology.
For her part, Communications and Digitalization Minister, Ursula Owusu Ekuful said the government is committed to embracing technologies as part of efforts in enhancing connectivity.
“Ghana’s unwavering commitment to embracing innovation has propelled us to the forefront of digital transformation on the continent and our government through its digital Ghana Agenda launched in 2017, instituted projects and programmes geared towards bringing the digital divide and ensuring digital inclusion for all sectors of the economy,” she said.

How to conceal objects from electromagnetic radiation has been a hot research topic. Radar is an object detection system that uses Radio waves to determine the range , angle, or velocity. A radar transmit radio waves or microwaves that reflect from any object in their path. A receive radar is typically the same system as transmit radar, receives and processes these reflected wave to determine properties of object. Different organizations are working onto hide object from the radar in outer space. Any confidential object can be taken through space without being detected by the enemies. This calls for necessity of devising new method to conceal an object electromagnetically.
Simultaneous information and energy transfer (SIET) is attracting much attention as an effective method to provide green energy supply for mobiles. However, low power level of harvested energy from RF spectrum limits application of this technique. Thanks to improvement of sensitivity and efficiency of RF energy harvesting circuit as well as dense deployment of small cell base stations, SIET becomes more practical. In this paper, we propose a unified receiver model for SIET in LTE-A small cell base station networks, formulate a feasibility problem with Poisson point process model and analyze the feasibility for a special and practical scenario. The results show that it is feasible for mobiles to charge the secondary battery with harvested energy from BSs, but it is still impractical to directly charge the primary battery or operate without any battery at all.

Electromagnetic interference caused by electric transmission and distribution lines on neighboring metallic utilities such as gas and oil pipelines became a major concern in the early 60’s due to the significant increase in the load and short-circuit current levels needed to . The hissing of high voltage transmission lines is due to corona discharge, not magnetism. The phenomenon is also called audible magnetic noise , electromagnetic acoustic noise, or electromagnetically-induced acoustic noise , or more rarely, electrical noise , or "coil noise", depending on the application.
Electromagnetic interference caused by high voltage power lines sharing the same corridor with railways can endanger the proper operation of the signal and protection systems of the railways under both load and fault conditions. The computation of interference effects in a typical right-of-way is a complex and time-consuming procedure. How To ID Power-Line Noise Many electrical devices, such as electrical motors, tools and appliances, can cause interference. The types of interference differ greatly from one electrical device to another. Interference caused by a computer, for example, is not the same as that produced by a .

Electromagnetic interference (EMI) is an important consideration for electrical systems and can come from many forms. This chapter discusses some of the common sources of potential EMI from electrical power systems including corona, scattering, Author: Benjamin R.T.
Cotts, Kevin L. Graf, William H. Bailey. The waves from power lines and electrical devices have a much lower frequency than other types of EMR, such as microwaves, radio waves or gamma rays. However, a low frequency wave does not necessarily mean that it is low energy; a charging cable for a phone produces a low frequency, low energy electromagnetic field, while a high-tension power.
Types. Electromagnetic interference can be categorized as follows: narrowband EMI or RFI, which typically emanates from intended transmissions such as radio and TV stations or mobile phones; broadband EMI or RFI, which is unintentional radiation from sources such as electric power transmission lines.; Conducted electromagnetic interference is caused by the physical contact of.

A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air.
A corona occurs at locations where the strength of the electric. Radio noise interference and corona power losses have been exten sively investigated in the field and laboratories [6, 9, 10, 16, 17, ].
Some theoretical analysis has been used to calculate the radio noise and corona power loss on high voltage transmission lines [7, 8, ]. Many approaches to analyze radio frequency interference were.

As described by Pakala and Chartier () power lines are divided into two classes with respect to radio noise: (1) lines with voltages below 70 kV and (2) lines with voltages above kV.
Lines in the first class in general exhibit only gap-type discharges and lines in the second class principally exhibit corona discharge.
Gap-type. Williams, in Instrumentation Reference Book (Fourth Edition), Electromagnetic interference (EMI) is a serious and increasing form of environmental pollution.
Its effects range from minor annoyances due to crackles on broadcast reception to potentially fatal accidents due to corruption of safety-critical control systems. Electromagnetic radiation from power transmission lines can influence the electronic devices nearby due to the corona discharge.
A numerical method is proposed to predict the radio interference based on the multi-conductor transmission lines mode and dipole mode. Finally some transmission line. Sheikh, A.
