What is a WiFi repeater and what advantages does it have?

WiFi repeater

A Wifi repeater is an electronic device that increases the power of your wireless network in your home or office. It receives a weak signal and amplifies it to distribute it to the corners that the modem cannot penetrate.

There are two types of connections available on Wi-Fi repeaters: single-band and dual-band. The single band allows you to connect to the 2.4 GHz frequency while the dual-band allows you to select between the 2.4 or 5 GHz frequency. We will cover this topic in-depth later.

What is a Wifi repeater?

A Wi-Fi repeater is an electronic device that amplifies the Wi-Fi signal of the modem. Helps bring the Wi-Fi signal to corners where most modems cannot reach by themselves. Although they have been used for a long time, they are becoming more popular thanks to the increase in wireless connections in homes and offices.
In general, Wi-Fi repeaters work omnidirectionally. This means that they receive a light signal and are responsible for enhancing it to later distribute it. However, there are also some hybrid repeaters that supply the signal through the electrical installation of the house.

Some Wi-Fi repeaters include Ethernet ports to connect a wide variety of devices at an even higher speed. In fact, despite how modern wireless may seem, the Ethernet cable is still the fastest and most stable way to get a good internet signal.

  • Amplify the wifi signal
  • Easy to configure
  • They are discreet devices
  • They are cheap
  • Improve network stability

What is the Crossband?

Crossband is a function that some of the dual-band repeaters incorporate and is used to connect to one frequency and repeat only the other frequency. This means that you can connect to the 2.4 GHz network and repeat the 5 GHz network, and vice versa. This feature is very useful to get the maximum benefit from the combination of the two frequencies. With this configuration, you can launch your network farther and surf faster, which translates into a faster and more powerful connection. We recommend looking for this feature on dual-band repeaters that you like.

Single-band or Dual-band – What should you pay attention to?

Most Wi-Fi modems offer to connect to the internet through two networks: 2.4 GHz and 5 GHz. The cheapest Wi-Fi repeaters will connect in a single band (2.4 GHz), while the most advanced ones connect in dual-band (2.4 GHz and 5 GHz).Single-band. This type of repeater repeats only the 2.4 GHz signal from the modem. This type of connection provides better coverage but transmits data at a lower speed. Its low frequency allows it to pass through floors and walls, making it very useful to reach more corners.

Dual-band. Dual-band repeaters transmit in both 2.4 GHz and 5 GHz and you can select the one you need just like on your modem. The difference is that the 5 GHz frequency is faster but has a lower range, so it is more difficult for it to pass through solid objects to cover distant spaces.

Single-band Dual-band
Frequencies 2.4 GHz only 2.4 and 5 GHz
Price economic More expensive
Speed Up to 300 Mbps Up to 3600 Mbps

How much does a WIFI repeater cost?

The price range of wifi repeaters varies in terms of the quality of the materials, as well as whether it is a single or dual-band. In general, a good Wi-Fi repeater of acceptable quality costs between $10 if it is a single band, up to about $75 if it is dual-band. The price will also depend on whether the device is made for indoors or outdoors. Any electronic device that withstands water and extreme climates is going to increase in price, but it might be worth it if that’s what you need.
