Point to Multipoint Bridge Link

I am currently working on a wireless solution at a campus that has a main building (Bldg A) and two remote buildings (Bldg B & Bldg C). The two remote buildings each have a 1232 access point that provides wireless access to the Internet via Linksys ADSL routers. At Site A there are 5 x 1232 access points providing wireless access to the LAN.

At each remote site the client wishes to discontinue the ADSL service and connect the access points to the main network at Bldg A. Bldg B is 80 metres from Bldg A and Bldg C is 30 metres from Bldg A. Bldg B & C are both in a 30deg beamwidth of the antenna at Site A. There is no Ethernet cabling connecting the sites so a bridge link will be required. The client requires a voice grade WLAN.

I am proposing the following solution

- BR1310 bridge with integrated antenna at Bldg A (root bridge) or a directional antenna such as a yagi or sector antenna.

- BR1310 bridge with Omni-directional antenna mounted on the roof of Bldg B (non-root bridge) associating to the root bridge at Bldg A

- Existing 1232 AP with 2.2dBi dipole antenna at Bldg C (non-root with clients) associating to the root bridge at Bldg A and providing wireless access to clients.

Can anyone advise if I can connect the Ethernet port of 1232 AP at Bldg B to the Ethernet port of the BR1310 (non-root bridge) to provide wireless access to clients via the 1232 AP. My reason for wanting to use the 1232AP is that I am not confident that the Omni-directional antenna will provide adequate signal penetration through the corrugated roofing steel.

Originally I wanted to use 1232AP?s with the ?A radios? providing bridge links and the ?G radios? providing wireless client access but from what I have understand the AP1232 can only be used in point to point configurations.

Thanks for your help.


Re: Point to Multipoint Bridge Link

I was going to have the same concern as you about using the 1232 for both bridging and client serving. Tying a bridge and an AP back to back is a valid configuration from what I have heard. I haven't had the opportunity to try it, though. I know that Cisco says tying 2 bridges back to back to serve as an intermediate bridge hop is a valid configuration, so I don't see why this would be any different.
