Trying to remember this information all the time is not easy, so we wanted to put this into a graphical representation for each main band. We have listed the 2.4GHz, 5GHz and the latest 6GHz bands available and shown only the UK availability. This removes the complexity as each country has different regulations, thus changing the channels allowed.
2.4GHz OFDM channels
There are limitations with channels 12-13 that not all equipment supports these channels.
5GHz
DFS and weather radar are highlighted. Some equipment has support issues in the weather radar range. Also, be aware that channels 149+ have power limitations and are recommended to be used only in high-density AP deployments. Channels 149+ for outdoor use requires a license.
6GHz
