Channel
The Wireless Channel sets the radio frequency used for communication.
●
Access Points use a fixed Channel. You can select the Channel used. This allows you to
choose a Channel which provides the least interference and best performance. In the USA and
Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access
Points use different Channels to reduce interference.
●
In "infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access
point. If more than one Access Point can be used, the one with the strongest signal is used.
(This can only happen within an ESS.)
IF using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same
Channel. However, most Wireless stations will still scan all Channels to see if there is an
existing "Ad-hoc" group they can join.
