2.4 GHz Wireless LAN Channels

When using 2.4Ghz Wireless LAN there are 14 channels however as these channels are 22Mhz wide there are in reality only three usable channels can simultaneously existing practically in one area due to channels overlap. Consequently in cases where wireless LAN is congested choosing an adjacent channel may not resolve a problem of interference, so a combination of both spacing channels apart as far as possible and changing polarisation maybe advisable to maximise the quality of connections.

Note the maximum EIRP is 4000mW.
