What is Powerline?

A Guide to Powerline Adapter in 2022

The need for Powerline to extend home network is growing. In this post, we’ll be explaining what Powerline is, who it’s for, and help users choose a suitable Powerline device.

What is Powerline?

Powerline products turn the electrical wiring of a home into network cables and transmit signals to every room. You can form a Powerline network wherever there are power outlets, eliminating the need for expensive and complicated Ethernet cables.

To form a basic Powerline network, you need at least two Powerline devices, whether wired or wireless ones. Different combinations of Powerline products help create a stable and unified network throughout your house.

Who needs the Powerline?

Powerline is ideal for people who live in big houses with thick walls and multiple floors as well as people who desire easy setup of a new network.

Some people may choose range extenders to expand their router’s network. However, sometimes thick walls and floors block the WiFi signals amplified by the range extender and still leave dead zones in your home.

With TP-Link’s Powerline adapters, there's no need for drilling or wire installation. You can turn your home’s electrical wiring into a high-speed network with ease. Every single adapter acts as a portable LAN port, transmitting a wired and wireless network to any place in your home where there's an outlet, regardless of physical obstacles.

Features of the Powerline

High Powerline Speeds

Using advanced HomePlug AV/AV2 technology, Powerline products provide stable and high-speed data transmissions where there is a power outlet. Stream in HD, game online, and download large files without interruption thanks to reliable Powerline links.

Wi-Fi Speeds

Most wireless Powerline devices support wireless the AC Standard. You can effortlessly extend a wireless network to share with all your WiFi devices in your home or office.

Ethernet Ports for Wired Connections

With Ethernet ports, Powerline adapters can run multiple high-speed and reliable wired connections at the same time for devices like smart TVs, PCs, and game consoles.

Extra Power Socket for Additional Devices

The integrated power socket means Powerline can be used like a traditional power outlet. Simply plug in your device or extension lead as though it were a normal wall socket.

How does Powerline Work?

Powerline adapters and extenders must be deployed in a set of two or more and be connected to the same electrical circuit. Using electric power conductors as the medium to send data, the adapters follow the HomePlug standard developed by the HomePlug Powerline Alliance. The currently used standards are HomePlug AV and HomePlug AV2.

HomePlug AV achieves a physical signal rate of up to 600 Mbps. It provides more bandwidth than previous standards for entertainment applications such as HDTV and home theater. HomePlug AV offers an easy, cost-effective solution to enable HDTV at home without new wiring. However, the latest bandwidth-hungry applications now ask for more bandwidth than is provided by HomePlug AV.

This brings us to HomePlug AV2, which operates with other HomePlug standards. HomePlug AV2 delivers Gigabit physical speeds thanks to its MIMO technology that establishes multiple simultaneous connections to improve data transfer rates, stability, and coverage—ideal for 4K Ultra HD video, online gaming, and Internet of Things. Home connectivity for the ever-increasing number of network devices is so much easier now.

Standard Signal rate Application
HomePlug AV Up to 600 Mbps HDTV, home theatre
HomePlug AV2 Gigabit physical speed 4K Ultra HD video, multi-room IPTV, online gaming

What are the Differences between Powerline and Range Extender?

  Range Extender Powerline Adapters
  • Flexible placement
  • No need for Ethernet ports and cable
  • Signals not influenced by the quality of electrical wiring
  • Plug and Play
  • Ability to send signals stably through an electrical circuit
  • No need for drilling or wiring
  • Internet from any outlet
  • Travels further without worrying about thick walls
  • Signals influenced by thick walls and large obstructions
  • Signals influenced by the quality and distance of electrical wiring

How to Set Up the Powerline Network?

Want to quickly set up a Powerline network and enjoy your network everywhere at home? TP-Link offers a very simple way of creating a Powerline network.

1. TP-Link Plug and Play

Simply plug a Powerline adapter into a power outlet and connect it to your router’s LAN port via an Ethernet cable. Then plug in another adapter or extender into a power outlet on the same electrical circuit. When the Powerline LED turns on, enjoy your newly extended network. Experience simple network management with our user-friendly tpPLC app, tpPLC Utility, and web interface.

2. Add a new device to the powerline network

Press and hold the pair button on the existing adapter for a second. Then, within 2 minutes, press the pair button of the new Powerline device. When the Powerline LED turns on, the new device has been successfully added to your Powerline network.

How to Choose a Suitable Powerline for Your Home?

Unlike range extenders, Powerline devices primarily extend a wired internet connection. But some Powerline devices can also extend a wireless network. To choose a suitable Powerline device according to your needs, you’ll need to consider the following:

1. How many Powerline adapters can be added to the same network?

It depends on the type of your powerline device. You can refer to "Max nodes in one powerline network" to find your model and the corresponding maximum number of devices.

2. Are TP-Link powerline products compatible with the powerline products of other brands?

For adapters of other brands, if they adopt the same standard, they should also be compatible with TP-Link powerline devices. However, they might have different ways to pair and configure. It would be much easier to use adapters from the same brand.

3. Can I use powerline devices across the floors in my house?

If these floors use the same electrical circuit with no filters, then powerline devices can work across the floors.

4. Do powerline devices have requirements on outlets?

Powerline devices rely on the electrical circuit to transmit data, while the power strips usually used may filter high-frequency signals. Therefore, plugging powerline devices on a power strip might affect the performance. We recommend plugging all powerline devices on the wall.

*Maximum Powerline signal rates are the physical rates derived from HomePlug AV/AV2 specifications. Actual Powerline data throughput and Powerline range are not guaranteed and will vary as a result of network conditions and environmental factors, including electrical interference, volume of traffic and network overhead, AFCI circuit breaker, and Powerline being located in a separate circuit.

*Maximum wireless signal rates are the physical rates derived from IEEE Standard 802.11 specifications. Actual wireless data throughput and wireless coverage are not guaranteed and will vary as a result of network conditions, client limitations, and environmental factors, including building materials, obstacles, volume and density of traffic, and client location.
