In the previous section, if you want a wider coverage of your own wireless LAN, you need to add a repeater. Then the question is, how to choose a repeater?
What is the role of wireless LAN repeater?
A wireless LAN repeater is a device that temporarily receives radio waves from a Wi-Fi router and relays the radio waves to terminals such as personal computers or smartphones in remote locations. Because it expands the radio wave range of the Wi-Fi router, it also eliminates complaints such as “communication is often interrupted in a bedroom far from the living room” and “radio waves cannot reach the room upstairs.”
How should I choose?
When choosing a wireless LAN repeater, please check the standard of the Wi-Fi router you are using. Even if the Wi-Fi router supports IEEE 802.11ac, if you install an IEEE 802.11n repeater, you will not be able to take full advantage of the high-speed communication performance. If your Wi-Fi router supports 11ac, please choose a wireless LAN repeater that also supports 11ac.
Secondly, you need to confirm the available frequency bands. The Wi-Fi (Wireless Local Area Network) standard uses radio waves of two frequencies, the 2.4 GHz band and the 5 GHz band, but the number of wireless LAN repeaters that correctly use these two radio waves is increasing. In addition, ELECOM’s wireless LAN repeater has a “relay mode”
The relay modes are:
-Optimization mode (standard mode): In the 2.4GHz band/5GHz band, the radio waves with better connections are mainly used for relaying.
-Single mode: only use one of the 2.4GHz band / 5GHz band for repeating
-Dual mode: use 2.4GHz band/5GHz band radio waves for relay at the same time
-Cross-band mode: 2.4GHz and 5GHz, radio waves in one frequency band are converted to radio waves in another frequency band and relayed.
Installation type select the type of wireless LAN repeater
There are two types of wireless LAN repeaters:
one is the type in which the plug connected to the host is directly inserted into the socket, and the other is the type that connects to the power supply through a cable. The advantage of the direct plug-in type is that the room can be clearly seen. However, if the location to be installed is far from the socket, you may need to use an extension cord, etc.
On the other hand, the type that is connected to the power supply by a cable has the advantage that it can be installed freely anywhere.
So when choosing a repeater in your home, you must see which mode and type is suitable for your home. In this way, choosing a repeater will not cause unnecessary trouble to yourself.
