11. 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.

12. 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.

13.  Example 2 – All clients communicate directly with each other. However, this method is not optimal as interference can occur with more regularity. BAT11B Ad-Hoc Operation
