Vinod, There is nothing in 802.11 that coordinates the channel assignment of APs. So by necessity, anything that does so is proprietary. However, there is new work being investigated in the IETF, called CAPWAP (control and provisioning of wireless access points) that would address this issue. There will be a BOF on this topic at the IETF in November.
As to your second question, the packets sent by P and Q will go to the AP each has associated with. The packets are addressed by the BSSID (AP's MAC address), not the SSID. How each node chooses the AP to associate with in the overlap situation you describe (and in all other situations) is also not described in the standard. Every implementation is proprietary and many are pretty lame. Because of some of those lame implementations, 802.11 is know as the "bug light" protocol in some circles. -Bob -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Geek Sent: Friday, October 31, 2003 8:44 AM To: [EMAIL PROTECTED] Subject: [BAWUG] AP channel allocation Hi everyone. I had some questions about AP Channel allocation and am hoping someone can answer those for me. When an AP is installed, its provided a static channel to work on. But i have heard that there are some intelligent AP's which can coordinate with surrounding AP's and choose the best channel to work on. Are such 'intelligent' AP's proprietary or part of the 802.11 standard? Would appreciate it if someone could describe the details of the protocol used in these 'intelligent' AP's. My other question is, If two co-located AP's(say AP1 & AP2) are assigned the same SSID and Channel number, and suppose there are two nodes(say P & Q) which are in an area overlapped by both the AP1 and AP2, then to which AP will the packets of P or Q go? Thanks in advance, Vinod __________________________________ Do you Yahoo!?
