Powerline Adapters – Buying Guide for Businesses and IT Resellers
Powerline adapters use existing electrical wiring to transmit data, eliminating the need for long Ethernet cables within a building. This proven solution is ideal where Wi-Fi signals are too weak, and running traditional network cabling is too costly or technically impossible. From basic AV600 models to advanced systems achieving maximum speeds of up to 2000 Mb/s, Senetic offers Powerline devices tailored to your IT infrastructure needs.
Below, we present a complete buying guide to help you choose the optimal adapter for your specific project.
What are Powerline Adapters and How Do They Work
Powerline adapters (also known as PLC transmitters – Power Line Communication) are devices that enable the transmission of network data through existing electrical wires in a building. The operation of Powerline adapters involves converting network signals into electrical signals that are transmitted through the electrical installation and then decoded back into network data on the receiving end. The signal transmitted by Powerline adapters does not interfere with the normal transmission of electrical power – both types of transmission coexist on the same wires.
Powerline adapters typically consist of at least two units:
- The transmitter of the adapter is plugged into a socket near the router and connected to it via an Ethernet cable.
- The receiver of the adapter is plugged in another room – where a network connection is needed.
This way, Powerline adapters eliminate the need for drilling walls and running network cables through thick walls or ceilings, which is significant in office buildings.
Powerline adapters are an alternative to Ethernet cables in cases of weak Wi-Fi signals and offer higher stability than wireless connections. This is particularly important in areas with high Wi-Fi density, where radio waves can be disrupted. Powerline does not require running Ethernet cables in the home or office – simply plug the devices into electrical sockets on the same electrical circuit.
However, it is important to remember the limitations. The choice of Powerline adapter depends on the condition of the electrical installation – Powerline adapters work best in modern buildings with copper wiring. Powerline adapters require a three-wire electrical installation for optimal performance, and their speed depends on the quality of the wiring, the length of the cables, and interference generated by other devices. It is important to avoid connecting Powerline adapters to power strips – Powerline adapters do not work well through extension cords or network filters. Direct connection to a socket improves the performance of Powerline adapters.
Types of Powerline Adapters for Different Business Applications
Every business environment requires a suitably tailored network solution. In Senetic's offer, you will find several categories of Powerline devices, varied in terms of functions and purposes.
Basic Ethernet Adapters
Models with a single Gigabit Ethernet or Fast Ethernet port provide a simple point-to-point wired connection. This is a good solution for offices, receptions, and workstations requiring a stable connection – for example, to connect a desktop computer, network printer, or POS terminal.
Adapters with Wi-Fi Module
Some Powerline adapter models offer an additional Wi-Fi network, combining transmission through the electrical network with a wireless access point. This is an ideal solution for conference rooms, open spaces, and common areas where employees use mobile devices. Newer models support Wi-Fi 5 (802.11ac) and Wi-Fi 6 (802.11ax) standards, providing better Wi-Fi performance compared to older standards.
Advanced Systems with Multiple Ports
Adapters with 2-3 Ethernet ports allow the connection of multiple additional devices without the need for a network switch. Models with a built-in electrical socket (passthrough) retain the power point – the additional socket allows the use of an occupied socket for other devices, which is particularly important when there are limited electrical sockets in the office.
Which Powerline Adapter to Choose
Different IT environments require varied network solutions. Below we present recommendations for typical deployment scenarios.
For Small Offices and Home Offices
Sets AV600–AV1000 with simple configuration are entirely sufficient for 1-2 devices. The installation of Powerline adapters is straightforward and often does not require configuration – simply plug both adapters into sockets and connect them via Ethernet cable to the router and computer.
For Medium-Sized Companies and Branches
Models AV1200–AV2000 provide higher bandwidth for greater network traffic. Adapters with a Wi-Fi module are suitable for handling employees' mobile devices, while systems with multiple LAN ports will enable the connection of printers, servers, and workstations. Powerline adapters can be used in different rooms if the sockets are on the same phase of the electrical installation.
For Demanding Multimedia Applications
Adapters AV2000 and higher are the choice for 4K video transmission, video conferencing, and online gaming requiring low latency. Models with traffic prioritization (QoS) allow higher priority to be given to critical business applications. In large office spaces, it is worth considering Mesh solutions in combination with Powerline for even signal coverage – Powerline can be more stable than weak Wi-Fi in challenging building conditions.

Frequently Asked Questions (FAQ)
Do Powerline adapters reduce internet speed?
Powerline adapters do not speed up the internet; they only transmit the existing connection from the router to a remote room. The data transmission speed will not exceed the speed of your internet connection. However, adapters may introduce some delay due to signal encoding and decoding – in practice, this is minimal (a few milliseconds) and does not significantly affect work comfort, even during video conferences.
What is the maximum operating range of a Powerline adapter in a building?
Manufacturers declare a range of up to 300 metres on a single electrical circuit under ideal conditions. In practice, large distances, the number of distribution boards, and the condition of the installation can limit this range. In most buildings with modern copper installations, adapters work seamlessly at distances of up to 100-150 metres. Powerline adapters can work on old installations, but the results are unpredictable.
Do Powerline adapters work between different electrical circuits?
Powerline adapters should be connected to sockets on the same phase of the electrical installation. The data transmission speed through Powerline adapters may be limited by different phases of the electrical installation – communication between different phases is technically possible but causes a significant drop in performance. In office buildings, it is advisable to check the phase layout and test the connection before purchase.
How many Powerline adapters can be connected in one network?
In one Powerline system, you can use several to dozens of adapters – the exact number depends on the standard and manufacturer (typically from 16 to 64 devices in one network). It is important to remember that each additional device shares the total bandwidth of the Powerline network, so with a large number of nodes, it is worth planning the network architecture considering the actual load.
What is the difference between a Powerline adapter and a Wi-Fi repeater or access point?
A Powerline adapter transmits the internet signal through the electrical installation, creating a stable wired connection in a remote room. A Wi-Fi repeater (signal booster) amplifies the wireless Wi-Fi signal, but loses quality with each hop. An access point requires a network cable to connect to the network.
Does a Powerline adapter require configuration?
The installation of Powerline adapters is simple and often does not require configuration. You just need to plug the transmitter into a socket near the router, connect it with an Ethernet cable to the router, and plug the receiver into a socket in the target room. Most models pair automatically. For increased security, it is advisable to use the Pair button, which activates AES 128-bit encryption between devices. In models with a Wi-Fi module, additional configuration of the wireless network (network name, WPA2/WPA3 password) is necessary.
What is the difference between the HomePlug AV and AV2 standards?
The HomePlug AV standard offers speeds of up to 600 Mb/s and uses OFDM modulation in the 2-28 MHz band. The HomePlug AV2 standard achieves speeds of up to 2000 Mb/s thanks to a wider frequency band, MIMO technology, and advanced modulations (QAM 4096).
