BAT11B Configuration
BAT11B Access Point Operation
Example 1 - the BAT in LAN 1 acts as an Access Point and the BAT in LAN 2 works as an Access Client. All clients in LAN 2 are connected to the AP in LAN 1.
BAT11B Infrastructure Operation
Example 2 – All clients communicate via the access point. However, all AC's have to be located within the range of the access point.
Example 2 – All clients communicate directly with each other. However, this method is not optimal as interference can occur with more regularity.
