The only solution for this is to make sure that your router is placed far from any smart devices like smart home appliances and smart bulbs.Īnother issue worth keeping in mind is congestion. Therefore, you might experience some interference between your router and these devices. One more thing that you should keep in mind is that the regular smart devices as well as the smart home appliances also use the UNII-1 channel for communication. Note: Higher channels are recommended because you will find less interference. The recommended 5GHz channels for home usage are UNII-1 (36 40 44 and 48) and you can go farther up and select the higher ones if your router has DFS and TPC. The Best 5GHz Channels For WiFi at Home, Office, Business Place It is not recommended to use this channel, even if you have a device that supports it. It is used for military stations and any type of sensitive communication. DSRC stands for Dedicated Short Range Communications and the 165 is the lowest channel which is a part of this band. This is the highest region and it is also known as DSRC or ITS. Besides, DFS and TPC are needed to enable your device to use them. This is because these are all higher channels, which means that they will have a wider bandwidth and better communication.
This band is also known as the ISM range because it overlaps with the frequencies that are specifically designated for Industrial, Scientific, and Medical purposes. UNII-3 Īlso known as the UNII upper range, this band features channels 149, 153, 157, 161. DFS allows the router to automatically select the best channel without creating any overlap with the weather and military stations or any radars. Your router must have the DFS and TPC enabled to use the channels from this band.ĭFS stands for Dynamic Frequency Selection and TOC stands for Transmit Power Control. They cannot be used by just about any device. This band consists of 4 channels as well – 52, 56, 60 and 64. This is also why there’s very high interference, but unless your router supports DFC/TPC, you’ll end up using this band. They are the lowest available channels at 5GHz frequency band and the majority of your home devices run on them. The first 4 wireless channels, that is, 36, 40, 44 and 48 are known as UNII-1 channels and they are generally used for domestic purposes. Let’s see what the purpose of each of these bands is: UNII-1
UNII stands for Unlicensed National Information Infrastructure. These bands are known as UNII-1, UNII-2, UNII-3, and UNII-4. The channels are further segregated into different bands and each band serves a different purpose.
