Local network through a socket: how to "make friends" the Internet with the power grid? Powerline adapters: home network by electrical wiring Local network by electrical wires.

Greetings!
Today's topic about Homeplug AV technology and PowerLine adapters working with it will be of interest to those who are too lazy to understand all the intricacies of the settings for a long time WiFi router or pull cables throughout the apartment, but really wants to connect the Internet to more than one computer in the apartment, or even to a TV or smartphone / tablet. And I want to please you - there is such an opportunity! And we will use the usual electrical wiring in your home to bring our idea to life - the Internet and WiFi will be where there is an electrical outlet.

About HomePlug AV technology and PowerLine adapters

A special device of the HomePlug standard, the so-called PowerLine adapter (I used a set from Tenda, allows you to conduct the Internet through the outlet). Or rather, several such devices - one for each computer. It looks like a small box with a plug - like charging from a mobile phone - and has an RJ-45 network connector under twisted pair.

The scheme of the network is outrageously simple - you buy several HomePlug adapters - as many as you need to attach computers. Insert a patch cord into one of them, connecting it to a router configured for an Internet provider. And you plug it into a power outlet - hence the name of the technology (“PowerLine” means “electrical wiring” in translation).

In the next room, you insert exactly the same PowerLine adapter and connect it with the same twisted pair cable to another computer - that's it, the Internet has been wired through a 220 V socket. The remaining parameters of the local network (IP, gateway, etc., etc.) are configured in the same way as if you were pulling in a standard way network cable.

How it works? The HomePlug standard, which underlies the described local PowerLine network, is characterized by the conversion of data received through the Ethernet network port into a high-frequency signal that is broadcast through the outlet to the electrical network. In another room, the same adapter receives no longer pure 220 volts, but a combined signal with transmitted data packets. It remains only to recognize this high-frequency signal, convert it and output it to the Ethernet network port, from where they come to another PC, or via WiFi.

This type of connection is much more stable than when using a regular WiFi repeater, since the interference is minimal and the signal quality hardly drops.

For clarity, look at the review of the product of one company that produces such adapters - by the way, they are made by all companies involved in the production network equipment so the choice is yours.

Powerline pros and cons

In spite of great convenience similar wiring of the Internet around the house, it has several disadvantages of PowerLine technology:

• The network only works within 1 meter and only in a single-phase electrical network, although only 2 wires (phase and zero) are enough for it
• The supported range is about 300 meters, but depending on the distance, the signal is received worse
• Powerful household appliances may interfere with operation.

And the last condition, which is self-evident, is that the house must have a configured local network through a router.

How to connect a smartphone via HomePlug?

But what does a smartphone have to do with it, you ask? And despite the fact that another one can be attached to such a device with a cable wifi router or access point. Moreover, there are Powerline adapters with an already built-in WiFi module, that is, by inserting it into a socket, you can bring the Internet through an electrical outlet not only via cable, but also wirelessly, which means you can connect to it from any device that supports WiFi without buying a separate equipment for relaying a wireless signal.

Therefore, I recommend not to be stingy and immediately purchase several of these adapters with already built-in WiFi - fortunately, they do not differ much in price from simple cable HomePlug adapters. Outwardly, they can be recognized by the presence of a characteristic antenna, although it may not be there - you need to look at the description on the box or in the instructions.

Unfortunately, at this method has its drawbacks. Firstly, working electrical appliances can create significant interference due to which the quality of communication and speed will drop. The total bandwidth of the network built on HomePlug adapters is divided between all clients, which means that the more computers, the lower the speed and reliability.

Secondly, the range of the network is limited to 200 meters and is highly dependent on the quality of the wiring. If the footage of most of us is quite satisfied, then the wiring in old houses without repair leaves much to be desired. But even if you live in a new house, it's too early to rejoice. In modern apartments, the power line often has a three-phase structure, in other words, not one, but three power grids work in the apartment at once. In this case, to implement the Internet through a socket, it is necessary to install a phase conjugation device in the electrical panel, which is located in the stairwell. But this problem is completely solved by calling a specialist from the house management.

talking plain language, it is best to connect these devices to mated, parallel-connected outlets.

Despite the shortcomings described, it's worth a try, especially since setting up these devices is very simple and will allow you to organize a local network over a very decent distance. If, when building a local network in a private house, you have to use several repeaters and antennas to stabilize wifi signal, or drilling ceilings and pulling tens of meters of cables, then for expansion it is enough just to buy an additional adapter.

The prospects for PowerLine technology are also very tempting - after all, in this way you can combine all household appliances into one smart system from single center controls on your computer - I think that this is a matter of a very near future.

How to set up HomePlug PowerLine adapters?

In the meantime, in our present, I will show you how to set up adapters to distribute the Internet through an electrical outlet.

We insert the first adapter into an electrical outlet, and connect it with a patch cord to the router in its LAN port. Subsequent ones - we connect to other outlets and connect to computers that will be part of our local network.

After going through all the purely technical steps of connecting cables and inserting devices into sockets, we find the “SYNC” or “PAIR” buttons on their cases.

We press them one by one on all adapters and they will automatically connect to each other and begin to exchange information. Upon successful connection to each other on the case, in addition to other indicators, the LED in the form of a “house” should light up. Also, with proper operation, the Power, Network and WiFi indicators should be lit (if available). wireless module).

As I already said, all other settings necessary for the operation of machines on a local network are made in routers and the computers themselves. However, you need to consider what IP addresses these adapters have by default in order to be able to get into their configuration panel. These data are most often indicated on a sticker on the adapter case.

I will give an example - PowerLine adapters from Tenda, which I purchased, have IP 192.168.0.254. Accordingly, the entire network should look like this - the router has an internal IP of 192.168.0.1, and the rest of the computers have addresses like 192.168.0.XXX, where "XXX" is a number from 2 to 253. If you have a DHCP client running on your router that distributes IPs automatically, then just change the address of the router to the above.

This also raises the question of security - after all, by purchasing an adapter from the same company, any neighbor who is somehow connected with your electrical wiring will be able to use your Internet for free. But this is not a problem either - to ensure maximum protection, a special utility is included on the CD, with which you can control all devices connected to the sockets from one PC. Let's look at one of these programs from TP-Link.

After installation, in the main window we will see the MAC address of the adapter to which this computer is connected. Click on it and press the "Connect" button.

If the connection is successful, "Connected on High Speed" will appear and the entire network will be scanned, and the detected adapters will be displayed in the list below. Notice the empty password field ("Password"). Click on the line, press the "Enter Password" button and manually set the unique key indicated on the sticker placed on the bottom of the adapter case.

We do the same with all devices from the list, after which we go to the “Privacy” tab - this is where security is configured. by default, the entire network is open, that is, a neighbor can easily wedge into it. But we can make it private. To do this, you need to set your unique name in the "Private Network Name" field in order to activate the DES encryption protocol. Next, click the "Set All Devices" button to add all the computers available in the local area to it.

That's all - now whoever tries to wedge in on you will fail.
That's all for today - try it, share your experience in the comments. By the way, the other day I ordered myself such a kit in China, so wait for a video review in three weeks.

Thanks! Did not help

Modern society simply cannot be imagined without the Internet. It has a lot of important features. With the help of the network, schoolchildren and students prepare for classes, teachers share their experiences, teenagers communicate with each other, adults get to know each other and create families. All these questions can be solved by the Internet. A person simply cannot imagine his life without the Internet.

Internet connection through the socket has become sufficiently widespread abroad. Russian providers do not really want to deal with a package of documents that must be provided to the electricity supplier in order for him to allow the use of the network using his system.

This type of connection has its drawbacks and advantages, which both attract new users and repel them from using it.

PLC (Eng. Power line communication) is a term that describes several systems for the use of power lines (power lines), for the transmission of audio information, as well as data. This network can transmit sound signals and data. This is done by superimposing an analog signal on a standard current that changes in magnitude and direction over time. A current that has a frequency of 50 Hz.

The PLC includes BPL (Broadband over Power Lines, which is a broadband transmission using power lines), which provides data transmission at a speed not exceeding 500 Mbps, and NPL (English, Narrowband over Power Lines, which is a narrowband transmission over transmission lines, the data transfer rate is much lower than the previous ones, that is, up to 1 Mbps.

Even at the time of the emergence of power grids, the problem of transferring information between power centers arose. For these purposes, telegraph and telephone lines were used, which were laid in parallel with power lines. However, a little later, such construction began to be considered irrational, and in the United States the practice of transmitting such information directly with the help of power lines was developed.

Note! The same information transmission system has become relevant for alternating current circuits.

What are Powerline adapters

Powerline adapters are a special line of devices for expanding the capabilities of Wi Fi networks. How the adapter works:

• with their help, a signal is received that comes from the router when connected by wire. To do this, they are installed at a close distance from the source;
• decode this signal in order to transmit the Internet over electrical network;
• at the output of the transmitted signal, the reverse process is carried out and transmitted to the Internet consumer via a cable connection or using Wi Fi. This technology is called Wi-Fi through an outlet.

Note! Similar devices are produced by almost all manufacturers of equipment for the network.

Along with devices that are produced for standard use of the Internet, great importance is given to the production of equipment for an alternative Internet connection. These are such well-known companies: Asus, D-Link, TP-Link, Edimax.

Who can use it

Internet over 220 volt wires is recommended for those consumers of IP-television and other services for whom connection speed is very important. When laying additional cable networks, there is a loss of speed, therefore, when using this connection method, additional costs for laying wires are eliminated and the inconvenience that can be caused by this process is avoided.

Note! This transmitter will be very useful in those places where laying a local network is categorically impossible or simply undesirable, and the Wi-Fi network does not provide sufficient quality of services provided by the provider.

How it works

Powerline adapters on their own are not designed to convert the Internet signal from the provider. It acts as an extension cord that helps extend the network within the home. That is, the Internet reaches the apartment using a modem or an Internet center. And then already around the house it diverges between consumers using HomePlug AV. Thus, the Internet through the outlet can be delivered to any of the rooms.

Important! The HomePlug AV is not a signal transmission device, it only serves as an extender for signal distribution.

Sockets in the house are interconnected. Each of them is connected to an electrical wire from a common source. This technology allows you to transfer the Internet over wires between all points electrical circuit. The maximum distance a signal can be transmitted with the adapter is 300 meters.

Note! Walls and ceilings do not interfere with the signal.

There is an option when Powerline adapters are connected in different rooms, you can connect to an Internet center in one room and to an IPTV receiver in another, and watch your favorite video without creating an extra cable network and any kind of additional settings.

Specifications

Internet technology at 220 volts and equipment for its connection has the following main characteristics:

• the maximum range of the signal is 300 meters;
• stable speed of at least 40 Mbps, and it does not decrease depending on the presence or absence of barriers in the form of walls;
• there is no speed limit on the technology of multicast streams;
• The network topology is similar to a bus organization, that is, two devices communicate along the shortest path between them.
• the frequency range that is typical for this type of device is in the range of 1.8–30 MHz and is characterized by 917 carrier frequencies and 155 existing ones;
• has the ability to use up to 64 devices belonging to the same network;
• the maximum throughput is 200 Mbps;
• works through a single-phase current meter;
• Internet over the mains can be used with any type of electrical wiring (aluminum or copper).

Advantages and disadvantages

Virtues of this type the Internet over the electrical network and its equipment are as follows:

• having a large number household appliances will not affect the operation of the adapter, from its operation the speed of Internet access via network 220 will not become less than that indicated in the main characteristics;
• the passage of data without delays that occur when passing through cable wired networks or via Wi-Fi;
• there is no need to run a cable, which can cause additional costs in connection with its laying;
• acceptable price of use;
• up to four networks can work simultaneously in the room;
• the speed of work does not depend on the type of wiring.

Some of the following are disadvantages:

• one device cannot act as a repeater between two others of the same kind, that is, due to such a combination, it is not possible to increase the maximum distance of the Internet through electrical wiring;
• electrical wiring, especially in houses of a fairly early year of construction, may not be of sufficient quality to transmit the Internet through the power grid, therefore, this technology most relevant for use in new buildings;
• voltage interruptions from a large number of operating devices are possible. In this case, it is recommended to use special filters that will save the consumer from this kind of trouble;
• for an Internet provider through a 220 socket, it is very difficult to document it. It is necessary to provide the power supply organization with all the necessary documentation for the service provided and obtain permission to supply it.

Description of the PLC adapter using the example of TP-LINK TL-PA2010

Specifications: HomePlug AV standard, maximum speed 200Mbps data transfer, compact design (almost the smallest size on the market), range is 300 meters, does not require special configuration, energy-saving operation, the panel has a single button to set the 128-bit encryption algorithm, supports the protocol IGMP, optimized work with digital television(IPTV).

Note! Appearance rather compact and outwardly attractive, has a white color, three green indicators are located on the front panel. It makes almost no noise during operation.

Setting up a PLC adapter using the example of a model from TP-LINK

This adapter does not have its own IP address. To configure it, you should use the special disk that comes with the kit. Installation is very simple and requires virtually no external intervention. To do this, you just need to click on the query with the word next several times. This word will be in English language next. After that, the adapter is connected to a power outlet and to a computer or other device using a cable.

During the installation of the program, a shortcut to the utility that needs to be launched will appear on the computer screen. The Network window will open by default. It will be empty because the connection has not yet taken place.

Note! At the next stage, the firmware is updated, which will help get rid of existing errors.

To carry out a flashing, go to the "Status" tab and check the version that is typical for installed firmware. If the firmware is updated to latest version, then you go to the TP-Link website and download the latest version of it. The download is fast enough, and the file is zipped. After opening the downloaded archive, the “System” tab is launched and the “Upgrade Firmware” button is pressed.

The NVM field is filled in with the path to the unzipped folder containing new firmware, the file with the NVM extension is selected. Exactly the same actions are carried out with the PIB field, only now the PIB extension is specified. After all the done actions, the “OK” button is pressed. These actions will start the firmware process, which in a couple of minutes will install a new version.

After the update, the adapter is ready for use. To do this, it is connected to the network and to the router, and the second is connected to the network and to the device with which the Internet will be accessed.

Important! Flashing must be done on all adapters that will be used. If somewhere the new firmware does not take place, then the device will not be able to work.

To add an additional device to the network, both adapters must be connected to a power outlet. Next, on one of them, the PAIR button is pressed. This button is held for 1 second. On the second device, the same must be done no later than 2 seconds after connecting the first. When adding the following devices, the same sequence of actions is performed. These steps establish a secure connection between devices.

Important! The adapter is connected exclusively to the outlet, since if it is connected to an extension cord, the data transfer rate will be much less than the established technical specifications.

Installation completed. The device can be fully exploited.

The choice of which type of connection to choose remains only with the consumer. But, before doing it, you need to carefully weigh the pros and cons, and then choose a really worthwhile offer.

Hey! Today's article will be a life revelation for someone, someone will simply pop their eyes into the screen, and someone will sigh with a smile in their experienced eyes. Yes! We'll talk about the Internet through the outlet. Yes, not just some special outlet, but about the most common electrical 220V. Interesting? Then this review article is for you!

About technology

PLC - Power Line Communication - communication through power lines.

For some reason, for many, this will be a real discovery. That's how it was for me at the time. It turns out that the Internet in the apartment can be transmitted through a regular outlet. And for this there are many modern devices. But for some reason, most people skip this technology. We will discuss the main reasons below. But is this magic really that new?

Not really. If you find an analogy in history, then you can recall telegraph lines, some of which were superimposed on power lines. Times go by, but no one even now prohibits the use of this method of data transmission at home. Indeed, in fact, any electrical wiring is the same cable with which you can be a little smarter.

Transmission is not limited to home electrical wiring. In theory, you can hook anything into the network - even trolleybus or electric locomotive lines. But in practice, this has not yet been personally encountered.

1. NPL (norrowband power line, narrowband transmission) - speed up to 1 Mbps.
2. BPL (broadband power line, broadband transmission) - speed up to 600 Mbps. It is this speed that is now used in home systems.

The last direction has 2 standards - HomePlug AV and updated HomePlug AV 2.0.

The latest standard and supports most modern devices. Perhaps right now, at the time of reading, something else has already come out, but so far everything is working well.

Application

There are not so few adapters on the market at the moment, here are some popular models and kits:

• TL-WPA4220
• TL-PA4010
• TL-PA4010PKIT
• ZyXEL PLA4201v2
• TL-PA8010 KIT
• TL-WPA4220KIT

The class of these devices is PowerLine adapters.

The main reasons for the use of such devices:

1. The need to expand the wireless network to another room where there is no way to run a cable or Wi-Fi goes out through the wall.
2. Connecting a computer under the same conditions via a cable - these adapters also have an Ethernet output.

Here is an example scheme of work in one picture:

Basic wiring diagram:

1. The head unit is connected by wire to the router.
2. The slave device receives the network and the Internet via electrical wires.
3. The slave device distributes the network to other devices via the Ethernet port or via Wi-Fi, if available.

It is also important to observe the following specifications:

1. With 50-60 Hz and 100-240 V, there are usually no problems, almost all HOUSES have such networks.
2. Ideally a direct connection to a power outlet is required. Some uninterruptibles do not support Powerline technology, and conventional surge protectors can dampen the signal - a reason to think if something is not working.
3. Interference can also be created by connected household devices to the same outlet - for example, a refrigerator. Check on all outlets!
4. Claimed to work at a distance of up to 300 meters. But in practice it is better not to do this, we take into account interference and attenuation.
5. During operation, the adapters tend to get very hot. Those. I would not risk leaving them in an unventilated place. But these are my personal thoughts.

What's in practice?

In practice, the availability of these devices alone pleases. Moreover, you can buy adapters both individually (after all, 2 devices are required for a minimum check), and ready-made kits. For example, TP-Link TL-WPA4220KIT:

Included:

• TL-PA4010 is the main PowerLine adapter.
• TL-WPA4220 - slave, 2 ports, Wi-Fi.
• Patch cords, documentation, box.

There are enough similar adapters on the market, so we will not dwell on them here in detail - if you have chosen your model, look for it on our website and read detailed overview. Here is just a brief summary of the functionality.

What opportunities do we have to connect:

1. Regular extension. We connect both adapters to the network, they automatically find each other. Both have a Pair button for pairing, but complete adapters find each other without it.
2. Network cloning. On the TL-WPA4220, the Wi-Fi Clone button is pressed, on the main router, the WPS button. We get a duplicated network. Those. in the second room, even through the outlet, there will be the same Wi-Fi without changing the network name and password.

For reference. The connection is encrypted using AES. Evil neighbors from the same organization will not be able to find out what bad site you visit at home.

Additional settings can be made in the old fashioned way through the web configurator, but it is available only when connected by wire. Yes, and there is no special need - everything works fine without that in pure pairing.

About “normal”: during the test, no drawdowns and discomforts were found. The Internet over the electrical network flew at the entire speed declared by the provider - about 90 Mbps. In the local network, the speed of colleagues accelerated to 170 Mbps. Those. even noticeable drops compared to the main router were not noticed, everything is on the level, you can use it!

Why isn't everyone using it?

Let's try to assess the current situation adequately. After all, what could be simpler - the provider connects the optics to a single house switch, and then each user issues his own PowerLine adapter. As a result - no wires, everything is clean, fast, works. But what is it really?

• Price. Nevertheless, such adapters are slightly more expensive than ordinary Chinese routers.
• Wiring. It is more profitable for the provider to be responsible for their twisted-pair cable to your apartment than to rely on the electrical wiring in our houses (especially if we are talking about something old, with 10 layers and balls of electrical tape).
• Matter of habit. Now a twisted pair cable has been introduced in large cities in almost all apartments. Previously used telephone lines. The transition to PowerLine technology is a new overlay on the already existing processes of reliable operation.

I won't push the subject further. Everything is clear - PLC technology shows itself well. The Internet flies over the power grid. There are enough devices in stores. And the price segment for such toys is quite pleasant - within 3000 rubles. you can find something suitable right now. That's it, leave a comment below!

There are more and more low-voltage cables for home networking every year. This includes:

• UTP internet cables and telephone wires

• cable for system “ Smart House”

• acoustic wires

• alarm and video surveillance

• TV cable

If earlier all this was simply thrown across the floor, behind furniture, in baseboards, today, when repairing an apartment, walls are also shredded for low current and special sockets are installed.

Consider in more detail the installation of TV sockets from companies such as Schneider Electric (Unica series) and Legrand.

Connecting a Schneider Electric Unica TV outlet

Specifications for television connectors from Schneider Electric:

The decibel value indicates the attenuation or attenuation of the signal.

Installation of all sockets must begin with cutting the coaxial cable. Leave a margin of 10-15 cm in length in the socket, cut the rest.

Now the most important thing is to decide how much insulation needs to be removed. To what depth and how many centimeters.

It is best to take measurements directly on the outlet itself. To do this, pick it up, apply the wire just below the viewing hole and mark with a marker or knife, the cut line at the level of the plastic central insert.

You can cut off the top layer of insulation as a specially designed tool

as well as a simple knife.

You can pick up an inexpensive stripper for a coaxial cable on ali-express.

Screen under insulation television cables found in different versions:

• only aluminum foil

• copper braided foil

• one braid in the form of thin wires

If the overall wire diameter is less than 7mm, then the screen is often turned outward to ensure sufficient contact with the metal socket cover.

Just keep in mind that from the inside of the shell, the foil does not conduct current.

This is where the main mistake of many electricians and television people when connecting a coaxial cable comes from - they hide all the veins of the screen behind this foil.

Therefore, at least half of its layer should be turned upside down. IN otherwise you simply will not have contact and a TV signal.

Types of TV sockets

Also pay attention to the icons and inscriptions on the case. There should be a symbol in the form of an arrow facing inward.

There is another arrow pointing up.

If your model has 2 arrows looking in different directions, then this is a pass-through TV outlet. That is, you put one cable from the antenna into the connector with an arrow down, and release the cable with the other or continue to pull the line to another connector, to another TV.

In general, there are 3 types of television outlets:

• single

• terminal - they have an additional resistor with a resistance of 75 Ohm (terminator)

• walk-through

Single and terminal ones will transmit a signal of the same quality, provided that a TV is connected to them.

If you do not connect a TV to a single outlet without resistance, then there will be interference and signal distortion on other TVs. Endpoints don't have this problem.

True, keep in mind that all this applies primarily to the analog signal. If you have a digital TV, or you are going to switch to it, then this resistor may cause problems.

You will either have to throw out this outlet and change it to another one, or connect it directly. These resistors dampen the signal a lot. Some channels will show poorly, or there will be no image at all.

All walk-through television outlets have an inlet and an outlet. An outgoing wire is connected to the output to another outlet or directly to the TV. Their main disadvantage is the degradation of the output signal by 4 dB.

Scheme for connecting multiple TVs through pass-through sockets:

You should also initially pay attention to the frequency of the socket signal. Models with a frequency of up to 1000 MHz are designed to work in networks with cable or terrestrial television. Instances with a frequency of over 1000 MHz are used for satellite television.

Cable connection

To connect the cable, remove the insulation from the central core by 6-8mm. At the same time, a couple more millimeters must be retreated from the edge of the outer shell to the place where the stripping begins.

Next, insert the TV wire into the socket and through the viewing window, control that the central core fully enters the socket.

In the Unica series, it is self-clamping, there is no need to tighten anything here. In other brands, there may be a clamping screw, which will need to be loosened first and then tightened with a screwdriver.

Pay special attention so that the “hairs” of the screen do not come into contact with the central core anywhere.

It remains to tighten the cable itself with the central screw and put the outer cover in place.

If something is not clear and does not work, you can always refer to the instructions.

Connecting a TV outlet Legrand Valena

Installation of the outlet, as usual, begins with its disassembly. The outer frame is attached to the latches. FROM reverse side press them with your fingers and remove the frame.

Next, you need to get to the inside of the outlet. Insert a screwdriver into the slot and move upwards to open the protective cover.

Inside there is a seat under the central core. In front of it is a wedge-shaped pin, which is driven under the top layer of insulation.

clean up coaxial cable and expose the central core by 8mm. In this case, the outer screen remains completely under the insulation layer. There is no need to expose wires and foil.

Insert the cable into the socket so that the wedge penetrates under the outer sheath of the insulating layer. In this case, the central core should go into its seat.

• central vein in the seat

• wedge under insulation

• the wire is tightly pressed to the side frame

After that, close the lid with a simple movement. Further, the frame together with the cable can be safely rotated in different directions and mounted on the socket.

• no need to install a separate piece of cable to connect the TV connector to the outlet

• no signal degradation. On the F connectors of the UHF range, the signal attenuates only from 0.1 to 0.3 dB.

All this is achieved by using ordinary plugs. Initially, lay a sufficient supply of cable in the wall so that it is enough for a direct connection to the TV (1-1.5 meters).

In the plug, drill a hole according to the diameter of the cable and lead the conductor through it.

It all looks as beautiful as on an ordinary outlet.

The only negative is that not all manufacturers have such plugs and may not be available on certain series.

Connection errors

The three most common mistakes that are made when connecting TV outlets:

Outcome - complete absence signal or poor quality.

If you have an analog signal, and several TVs are connected in series through a special splitter, then the resistance here will also be superfluous and it is better to get rid of it.

If no equipment is connected to these connectors (sockets), on other TVs, some of the channels will again show poorly and interference will be observed.

As a result, only the inner part of the foil remains outside, which is not conductive. Accordingly, there will be no contact between the screen and the socket connectors.

PLC adapter from Rostelecom is a device that allows you to transmit an Internet signal over an electrical network. Such equipment will help get rid of laying additional wires in an apartment or a private house.

Now most people have a wireless network in their own house or apartment. You might think that Powerline (aka HomePlug), which uses your home's electrical wiring as a wired data network, is outdated and useless technology.

Such an assumption would be incorrect. Yes, Wi-Fi is convenient and fast - 802.11n technology is widespread, and the latest 802.11ac class routers provide connections at speeds up to 1300 Mbps.

Important: the simplicity and reliability that Powerline offers, wireless technology still cannot provide. It is not intended to replace WiFi networks. These technologies complement each other.

What is a powerline network?

Powerline is essentially a wired network. Let's say you have a broadband router in the hallway and a smart TV in the living room that doesn't support wireless communication. The only way to enjoy digital TV is with an Ethernet cable running from the router down the hallway and living room floor. You can try to hide the cord under the baseboard. But, if the apartment has recently been renovated, starting it all over again because of one cable will not be the best idea.

PLC adapter from Rostelecom will not require complex schemes to connect it. He is practically invisible. The base kit comes with two Powerline adapters and a few short Ethernet cables.

The scheme is simple, we connect one Ethernet cable to the router and the other to the first adapter. Then plug it into the nearest outlet. We connect the Ethernet cable to the HDTV and the second adapter. We insert the latter into the nearest outlet. The adapters automatically detect each other (no drivers and no lengthy configuration process) and connect. This allows data packets to be transmitted from the router to the TV through the electrical wiring in the walls.

What is the connection speed?

When the first HomePlug Powerline standard was introduced in 2001, data transfer rates were limited to 14 Mbps. But the latest PLC adapters for Rostelecom support Gigabit class networks, providing positive reviews even among GPON Internet users.

Why Use Powerline Networks?

If you already have a wireless hub, you may not see the point in purchasing Powerline adapters for your home network. But the technology has a number of advantages over Wi-Fi, namely consistent speed, reliability, security, and ease of use.

By setting up a network using a PLC adapter from Rostelecom, you can cover places where the wireless connection is of poor quality due to a large number overlaps or other interference in the signal path. This option will also be convenient when connecting equipment without WiFi support, like legacy game consoles, while avoiding cluttering your living room with Ethernet cables. Powerline is a neat and efficient networking solution.

Important: Technology is safer than wireless networks. Since data is transmitted over copper wires in your home, you can be sure that only you will have access to the connection.

Some sets of PLC adapters allow you to additionally protect the connection with a password.

How do Powerline networks work?

Sending signals over electrical wires at home is not a revolutionary idea. Power companies began sending control signals over such networks as early as the 1920s. This ensures that electricity meters know when to go to off-peak speed. Electrical wiring in homes can support different frequencies. Usually 50/60Hz signals are used. Additional data can be transported over the same wiring at higher frequencies without causing any interference.

The first of the standards made it possible to achieve a data transfer rate of 14 Mbps. Already in 2005, the upgraded version increased throughput up to 200 Mbps, which is more than enough for video streaming.

Before connecting the PLC adapter, you need to find out if it supports your type of electrical network, provided that the purchase was not made from the Rostelecom operator. The device will make it easier to connect to the Internet for many users who, for various reasons, cannot lay an Ethernet cable.
