Wi-Fi Wired & Powerline / Homeplug Extender

Wi-Fi wired and powerline extenders (which often use the Homeplug standard) provide another method of extending the coverage of Wi-Fi routers.

Wi-Fi repeaters and boosters provide one method of extending the coverage of a Wi-Fi router.

Another method is to use a wired or powerline link to provide the data connection between the main router and the second access point.

Using a wired link between the main router and the second access point overcomes the issues of slowing the network to allow for repeating the data.

It also means that a wireless link is not needed to provide data for the subsidiary access point or points, enabling them to be located exactly where they are needed.

Powerline Wi-Fi extenders

One of the easiest methods of establishing a wired connection between the main router and a second or subsequent access points, i.e. the Wi-Fi extender is to use wiring that is already installed, i.e. the mains or power wiring in the office or house.

Data is able to be transmitted over the power wiring - the high voltage being blocked and only high frequencies allowed for carrying the data along the power line. In this way the line frequency does not interfere with the data transmission.

To achieve a connection, a powerline adapter is directly connected to the main router via an Ethernet cable or other suitable cable. The adapter is then plugged into a power socket, allowing network data to travel via the electrical system into a receiving adapter, i.e. the remote Wi-Fi extender in another location. At the remote end the data is extracted from the power line and either radiated on a Wi-Fi signal, or it can be connected directly via an Ethernet cable dependent upon the power line extender.



The power line Wi-Fi extenders can often use the Homeplug standard for transmitting data over the mains wiring. This is an established standard that has been in use for many years.

A power line Wi-Fi extender is very useful as it requires little installation. The main precaution to note is that the two power line adapters should be on the same mains wiring ring, otherwise connection may not be achieveable.
