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.
