WiSM - Branch office AP's

We are building a new site and we are planning on installing a WiSM at the main site. We also have 9 Branch offices that are connected via CSME (OPTEMAN) on 2821 routers at speeds ranging 10mb - 100mb. Question: Can the WiSM control AP's at the branch office or do I need to purchase a WLAN controller module for the 2821's? If the CSME circuit goes down the site loses the wired connection so wireless connectivity doesn't matter if the circuit is down.

Thanks in Advance!!

It can...I have a site connected with a 1.544Mbps link with 2 access point.

Re: WiSM - Branch office AP's

You have 3 options:

1- Local APs (Any model), the traffic would all go back to the WiSM, or

2- REAP APs (1030 only) - users are authenticated back at the controller, but the traffic stays local to the branch office.

3- Hybrid REAP (11xx/12xx models) - Traffic can be bridged locally or brought back on a per-WLAN basis (best of both worlds).

In any remote scenario though, latency is a bigger issue than bandwidth -- make sure that the link is not more than 100ms, as otherwise there may be authentication issues.
