Network Basics: Wi-Fi Repeater, What It Is And How It Works

A Wi-Fi repeater is a network solution that allows us to expand, in a simple and inexpensive way, the scope of our Internet connection. Unlike PLC devices, which work in a wired way and move the signal of our connection through the electrical network, repeaters do it completely wirelessly , something that, obviously, is an important advantage .

Due to its simplicity, ease of use and low cost, the Wi-Fi repeater has remained one of the favorite options when it comes to extending the range of a wireless network, and it is understandable, since we can find very cheap models , and these can be configured in less than a minute, if we use the WPS button.

How exactly a Wi-Fi repeater works

The Wi-Fi repeater is a network device that collects, reproduces, and amplifies, the wireless signal that emanates from our router , or from another repeater, in order to take it to other corners of our home or office where we do not have Internet. This means that:

  • Repeats the signal it receives from these devices, keeping the network name and password.
  • It extends that signal emitting it from its own antennas , which means that the signal will reach other areas with greater intensity, and the connection will be better.
  • They have their own security settings , and more advanced models can be used to create mesh networks .

However, it must be taken into account that, as the Wi-Fi repeater takes the source signal from the router, or from another repeater, it must receive it in good condition, otherwise it will not be able to repeat it optimally. This nuance is very important, because if we place the repeater too far from the router to try to maximize its range, we may end up having problems.

Why are Wi-Fi repeaters so popular?

Well, mainly because of their ease of use, because they usually offer a good value in relation to price-performance, and also because they are a more suitable option for the concept of modern home and office, where multi-device environments prevail (multiple devices connected to the Internet simultaneously).

However, this does not mean that a Wi-Fi repeater will always be the best option, since they also have disadvantages compared to PLC devices . These, when working wired, usually offer higher performance and greater stability, which makes them an ideal solution for connecting devices that are very sensitive to latency and packet loss, game consoles and gaming PCs, for example. .

Deciding between a PCL and a Wi-Fi repeater can be complicated, but luckily there are also PLC devices with Wi-Fi repeater functions . These are, in my opinion, the best option in most cases, since although they are more expensive, they compensate for their high price by offering a much more interesting value.
