Review of PLC - adapter. Advantages and disadvantages. PLC adapter from Rostelecom: prices, reviews, how powerline works The principle of operation of Powerline networks

Powerline technology can become a panacea for problems with poor Wi-Fi signal or eliminate the need to run wires into a distant room. Data transmission via an electrical network is an excellent solution for apartments, private houses, and large offices. No complicated settings, no tangled cables - just plug it in and use it.

Fly in the ointment in technology

To avoid this being a laudatory article, let’s immediately talk about the disadvantages of the technology, although they are already quite obvious. The most modern standard today HomePlug AV2 reaches speed up to 500 megabit/s. But this figure is a theoretical maximum. Even if the quality of the electrical wiring is excellent, there are no transformers and you are in the same phase of the electrical system, you are unlikely to see such numbers. In practice, the data transfer speed may differ markedly from the numbers on the box. Buy 500Mbps or 600Mbps Powerline if you can. You should get twice the speed you would get with a 200Mbps Powerline

What is Powerline and why do I need it?

Powerline technology allows you to use electrical wiring to transmit data over an ethernet network. Each kit contains at least two adapters and ethernet cables. All you need is to plug the adapters into a 220V socket in your apartment. Powerline will allow your devices in another room to easily access the Internet - you can connect a laptop, router, TV, console, anything.

Powerline VS Wi-Fi

The technology of data transmission via an electrical network has an advantage over Wi-Fi technology, because... Data transfer speeds in remote areas vary significantly! Moreover, Poweline can also act as a repeater (many kits can “clone” a home Wi-Fi network).

In addition, the “range” of the Powerline W-Fi adapter is undoubtedly further than that of Wi-Fi access points - this becomes possible because for Wi-Fi the presence of walls and background “noise” in the radio air is very critical, while while network adapters can operate up to 300 meters (theoretical speed).

FAQ:

What if there is only one outlet in the room?

Many adapters are equipped with a regular power outlet, so you don’t lose the ability to plug a lamp or other electrical device into the mains.

Is a local network created between adapters and devices connected to them?

Yes it is possible. A network via Poweline is no different from a regular LAN. There are two ways to configure a network based on a power line, the first method is using the utility TP - LINK, the other - with the help pairing buttons. This section will discuss how to use the pairing button to set up such a network.

General setup diagram

My network voltage is jumping, is there any point in buying Powerline adapters?

There is a point - the fact is that they can operate in the range from ~120 to ~240 V, so they can easily withstand fluctuations in the network, but this, of course, will affect the data transfer speed.

Low network speed. What could be the problem?

Maximum network speed through electrical wiring cannot be achieved if:

1. The distance is too large. Too great a distance can greatly degrade the signal quality and speed as a result. Theoretically, the speed in technology can reach 300 meters, but in conditions where the wiring in houses is not in the best condition, it is better to stick to the figure of 100 meters

2. Charging for your phone or laptop in the house is connected. Huge interference in power lines is caused by chargers for tablets, smartphones, etc. Moreover, regardless of which socket and how far from the adapter they are connected. Especially concerning various Chinese chargers

The best for 2017-2018

The kit always includes at least two adapters. To create a Powerline network, at least two adapters are required. When making a purchase online, make sure that the price is for the set and not for one adapter. The rule of good form is to include at least one ethernet cable in the kit.

TP-Link AV2000 2-Port Gigabit Passthrough Powerline

Price: ~ 6800 rubles
Wifi: No

Two (!) Gigabit ports on each adapter allow AV2000 achieve the best speed among our current adapters! Tests in one room showed the result 430 Mbit/s! At a distance of two walls and 30 meters the result was 110 Mbit/s - and this is the same best result in tests. The only serious omission in the AV2000, in our opinion, is the lack of a Wi-Fi module.

RESULT: Only because Wi-Fi given the model did not receive the Editor's Choice award. Only Gigabit Ethernet, only hardcore!

TrendNet Powerline 500AV2 Adapter Kit

Price: ~ 3400 rubles
Wi-Fi: With a separate device - yes

It also has a Gigabit-Ethernet port on board, which is a huge plus considering the low cost of the kit. The downside is that one adapter in another room may not be enough (Smart TV, Game console, Laptop) and so on. But for this, fortunately, TrendNet has a Wi-Fi adapter, which, however, has a bar of only 100 Mbit/s, but even this result is better than a regular Wi-Fi connection in an apartment. In order to. Speed ​​was tested in rooms between floors and was quite good ~150 Mbit/s. The speed via Wi-Fi was also a pleasant surprise - 60 Mbit/s. Please note that for Wi-Fi usage you need to buy a separate device - TrendNet Powerline 500 AV Wireless Access Point

BT Wi-Fi Home Hotspot 500 Kit

Price: ~ 3400 rubles
Wi-Fi: yes

Well, if 100-megabit ethernet ports BT Wi-Fi Home Hotspot 500 Kit may disappoint you, lovers of stylish gadgets will definitely like it. It produces average speeds. With a standard set of electrical appliances on the network (TV, microwave, lighting lamps), the adapter gave 95 Mbit/s on another floor of the apartment. Not bad? Considering the state of the wiring in the tested house - very much so. But the Wi-Fi was great - 54 Mbit/s. Can you achieve this speed with a standard router across one floor?

Devolo dLAN 550 Wifi

Price: ~ 7350 rubles
Wi-Fi: yes

This kit has a slightly strange layout - the main adapter has two ethernet ports (10/100, forget about gigabit, it’s in the older model). And for some reason there is only one Wi-Fi access point (additional module). Although it can be assumed that in a remote room, on the contrary, more cable connections will be required. Devolo dLAN 550 Wifi can clone your home Wi-Fi network - just enter the same username and password as on your router. Cable speeds are not impressive - the test showed a modest 80 megabits, but Wi-Fi speeds are already excellent 72 Mbit/s . RESULT: It becomes obvious that, first of all, the kit is worth buying for those who want to use exclusively wireless technologies in the home. Strong Wi-Fi module

Netgear Powerline PLP1200

Price: ~ 4560 rubles
Wi-Fi: no

They have a built-in socket, but are poor in other interfaces: only 1 ethernet port (though gigabit) and the absence of a Wi-Fi module. Don't be confused - the PL1200 version does not have a built-in socket (PLP only). Doesn't shine with speed - pretty standard 95 Mbit/s via cable across the floor. The adapters have LED indicators that show the signal strength. “Red” - average, speed less than 50 megabits. Green means good connection (60-80 Mbps). RESULT: For this price I would like more.

Asus PL-AC56 AV2 1200 Wi-Fi Powerline Extender

Price: ~ 9000 rubles
Wi-Fi: yes

The coolest and most expensive kit: Built-in socket, 3(!) Gigabit Ethernet ports, Wi-Fi module with external antennas. Everything tells us that this is a real monster. Wi-Fi can operate in both the 2.4 Ghz and 5 Ghz bands—the only one in the review. Naturally, “cloning” a home Wi-Fi network also works. In one room the adapters show very high speed - 345 Mbit/s. At a distance of two (!) floors, the test showed 109 Mbit/s- the result that other sets show with a difference of only one floor. But when testing Wi-Fi, the result was at the level of other participants - ~50-60 Mbit/s. Why then these two antennas? Obviously, they allow you to significantly expand the range, but this does not greatly affect the speed. RESULT: If you don't mind the money, then this Kit is a definite Must Have

And TV is popular among users, so the number of subscribers is constantly increasing. PLC adapter is modern technology transmission of communications over electrical networks. Such technologies are constantly evolving as electricity is widespread in most regions. They are used to automate existing processes that require automation, organization of security systems, including the installation of video surveillance. In addition, such adapters are installed to create technologically advanced premises - “smart houses”.

In order to provide the user Better conditions Research is constantly being conducted that is aimed at studying the field of data transmission. The use of PLC did not develop, as this technology was hampered by the low speed of the Internet, but today this problem has been practically solved, which has eliminated many inconveniences and problems in this area. In addition, the improvement in the performance and power of processor chipsets had a positive effect on the development of PLC adapter technology. These devices use familiar and common electrical networks. They carry out constant data transfer.

Their work is based on principles identical to ADSL over telephone lines. In both cases, the incoming high-frequency signal is superimposed on a conventional electrical signal; in addition, in this case, the functions and technological capabilities of the device itself are used. Since the technology is still developing, it has a number of positive and negative factors that should be taken into account if a person wants to put it into practice. The main pros and cons of the technology must be considered with utmost care. So the PLC adapter helps to establish high-quality and uninterrupted provision of a number of services. For example, these include Triple Play, since it does not require the laying of additional or special wires for transmitting information data, therefore, a person will not incur additional financial or time costs, which will save budget funds, but obtain high quality from the operation of the equipment.

The advantages also include fast and fairly simple installation, and the ability to connect to already existing functioning networks. In addition, such an adapter can be easily disassembled and configured if necessary. Such functions are indispensable if you are planning to move. A network created using this technology can be scaled without difficulty and special knowledge - this allows you to quickly organize a topology with minimal costs. In difficult conditions, the created network will not fail. It will need to be used if the building has reinforced concrete or other similar structures, for example, covered with foil-type insulation, in cases where various types of interference are observed, ranging from electromagnetic to natural. At the same time, the user receives complete network security from unauthorized access to existing data, as the most modern encryption algorithms are used.

Meanwhile, despite the obvious advantages, the system also has a number of disadvantages that should be taken into account. Chief among them is reduced bandwidth as the network shares it among all users connected to it. Also, the stability and speed of operation of the PLC adapter is greatly influenced by the quality of the existing electrical wiring. You should also keep in mind that PLC does not work through conventional surge protectors and uninterruptible power supplies popular among users, unless they have special sockets called PLC Ready. Other disadvantages on this moment not detected. You can find out about other technical innovations on the website mts.one.

Optional equipment PLC adapters

PLC adapters are the optimal solution that will allow you to connect Home TV without laying additional wires and enjoy watching TV channels and videos in digital and HD quality in any convenient place in your apartment.

“PLC adapters do not require special settings and have a number of significant advantages - fast connection of services, no installation work and ease of use.

The kit includes two PLC adapters for transmitting data over a regular 220 V power supply network, which allow you to organize a local network at speeds of up to 200 Mbit/s, maintain signal quality and use one socket for both the adapter and an optical router or TV.

Thanks to the simple installation, the connection can be carried out without the help of a specialist. The connection configuration can be changed “on the fly” by the user simply by rearranging the adapters within the apartment.

Advantages of PLC adapters for IP-TV

Possibility of connecting a TV anywhere in an apartment or house without laying a cable:

• no need to run additional wires to the TV set-top box;
• simplicity and reduced connection and switching time.

Connecting and setting up a PLC adapter for IP-TV is quite simple:

• connect the transmitting PLC adapter to the ONT device or ADSL modem/WiFi router;
• connect the receiving PLC adapter to the TV decoder;
• The Power Line (PLC/ACT) LED on both adapters should light up red, orange or green(standard/good/excellent connection speed). PLC adapters are ready for use;
• if the Power Line (PLC/ACT) indicator does not light up, there are buttons on each adapter that must be held in turn for 5-9 seconds; after which the indicator on both adapters should start blinking (device search mode), then light up constantly. PLC adapters are ready for use.

The Internet plays a significant role in the life of any person, and there are several ways to connect to it. In addition to the usual local networks and fiber optic connections, data exchange using electrical wiring with adapters is gaining popularity. The method was invented a long time ago, but has not found wide application until now. All more people are interested in transmitting data over home wires. The solution is effective when it is not possible to lay a network cable to the premises, and the quality of the wireless connection leaves much to be desired. Today we will look at what an MGTS plc adapter is, discussing the advantages and disadvantages of the feature, as well as the principle of its operation.

On what principle does the network operate and what adapters exist?

Speaking about the features of plc-type networks, it is important to note that the very principle of their operation is not much different from a connection via a fiber optic cable. The difference is that the network we are considering can transmit data over familiar home wiring at high speed. There is no need to connect a special Internet cable or catch a signal via a Wi-Fi network.

For the system to function, you must purchase a set of adapters consisting of two devices. One is designed for connecting to an electronic gadget or router, the second is for connecting to a router. Both devices are connected to an electrical outlet (outlet).

The principle of operation is that the MGTS plc adapter converts electronic data into signals high frequency, after which it transmits them along with the current voltage. IN reverse order alternating current is converted into electronic information, displaying it on a computer. The frequency of transmission of electrical impulses through wires is 50 gigahertz.

There are three types of direction adapters:

• Equipped with an Ethernet connector. With their help, electrical impulses are converted into information that is transmitted to a computer via a standard Internet cable.
• Equipped with a Wlan module that transmits data wirelessly. Devices from which you plan to receive information must support Wlan technology - this is a prerequisite.
• With a socket for connecting to a satellite dish. Relevant for those who plan to broadcast data from a satellite to a computer.

The need for a particular receiver is determined by requests and technical capabilities in each individual case.

Pros and cons of technology

If you are considering the advisability of purchasing a set of plc equipment, pay attention to the advantages of this type of connection:

• Compact and mobile. The MGTS PLC adapter will be an excellent solution for people who have a negative attitude towards all kinds of wires. Some people are simply annoyed by the sight of them around the apartment, others are worried that the cable will be chewed by a pet or touched by a child. PLC networks operate from a socket into which the adapter plug is inserted; there is no need to lay wires around the apartment. Do you want to change the signal range? Reconnect the device to a different outlet and continue using the network.
• Possibility of increasing the coverage covered by the signal. Any gadget in the house is connected to the network using the additional installation of one or more adapters. Experts recommend not installing more than 15 adapters in one home, since a large number of connected devices reduces the connection speed. This opportunity is attractive because a new connection can be made instantly. The installed adapter does not transmit the Internet signal to the next room? Make sure that every room is equipped with the Internet and use the network without restrictions.
• If the Internet is transmitted using Wlan technology, the range of the network is quite high, especially if the room is not equipped with a large number of partitions and other obstacles to the signal.

Agree, it is very convenient to use the service, having the opportunity to independently adjust its operation. The operating principle of the Power line communication network is designed for exactly this.

There were also some downsides. The first disadvantage of the system is that the adapter may interfere with radio waves. Since Internet communications are transmitted in the same way as information for radio receivers, pairing them leads to interference with the radio receivers.

Electrical devices used in everyday life also affect the quality of the Internet. The signal may weaken when you turn on the microwave, kettle or washing machine, but the voltage returns to normal as soon as the additional device stops consuming electricity.

Channel speed and security

If we consider technology from the point of view of data transfer speed, we can note four existing communication standards: Home Plug 1.0./1.01 turbo/ AV DS 2200 and IEEE P1901.

The declared speed of the first type of data transfer is 14 megabits per second, but in fact the adapter operates within 4-5 megabits/second. Sufficient for minimal manipulation on the World Wide Web or use social networks. The second type works faster - with the stated 80 megabits, you can use 30. The third standard is considered the highest speed - actual 70-75 megabits with a theoretical 200 Mbit/sec. Most modern adapters operate at this speed. As for IEEE P1901, the development is quite new, but it promises to interact at a speed of 500 Mbit/sec. How in reality is still difficult to answer.

From a data security point of view, the creators will have to do some more work here. Despite high level encryption, a neighbor who knows the password can connect to the network (the default adapter passwords are the same). Keep this in mind and change the settings immediately after activating the development.

We looked at plc technology. As you can see, it has many advantages. Feel free to purchase a set of equipment and connect computers and televisions to the network, its cost is quite budgetary - 3,000 rubles.
