WiFi Channel Planner
Pick a band and channel width, set how many APs you will deploy and get a channel plan with maximum reuse and no overlap. Detects co-channel and overlap interference on the fly. Everything is computed in your browser.

How overlapping works
In 2.4 GHz each 20 MHz channel is centered every 5 MHz, so two channels overlap if their difference is less than 5 (|c1 − c2| < 5). That is why the classic plan is 1 / 6 / 11: they are the only three that do not step on each other.
In 5 / 6 GHz the 20 MHz channels do not overlap with each other; overlap appears when you do bonding (40 = 2 contiguous channels, 80 = 4, 160 = 8). Two APs sharing any subchannel interfere. Channels marked DFS must yield to radars (waits and possible channel changes).
