Common Wi-Fi Channel Ranges: 2.4G and 5G (5.2G / 5.5G / 5.8G)

2.4 GHz band

The 2.4 GHz band is split into channels spaced by 5 MHz. Depending on region, channel availability differs. 40 MHz operation is typically formed by bonding adjacent 20 MHz channels.

5 GHz band

5.2G band

Common channels include 36, 40, 44, 48, 52, 56, 60, 64.
In some regulatory domains, DFS channels (such as 52-64) may be restricted or require radar-detection behavior.

5.5G band

5.5 GHz is part of the broader 5 GHz allocation. Channel plans vary by country/region.

5.8G band

In CN rules, common channels are 149, 153, 157, 161, 165.
Typical bonding examples:

80 MHz: 149-161
40 MHz: 149-153 or 157-161
20 MHz: channel 165 only
