Wireless Backhaul; Point-To-Point Bridging - Cisco Aironet 1520 Series Manual

Wireless Backhaul

The access point supports wireless backhaul capability using the 5-GHz radio to bridge to another
access point to reach a wired network connection to a controller (see Figure 2). The access point
connected to the wired network is considered a RAP in this configuration. The remote access point is
considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network.
Lightweight access point protocol (LWAPP) control traffic is also transferred over this bridged link.
The LAP 1505 model uses the 2.4-GHz radio for backhaul and wireless client operations.

Point-to-Point Bridging

The access points can be used to extend a remote network by using the 5-GHz backhaul radio to bridge
the two network segments as shown in Figure 3. To support Ethernet bridging, you must enable bridging
on the controller for each access point.
The LAP 1505 model uses the 2.4-GHz radio for bridging operations.
Note
Wireless client access is supported; however, if bridging between tall buildings, the 2.4-Ghz wireless
coverage area may be limited and possibly not suitable for direct wireless client access.
