!RE: [WIRELESS-LAN] AP Bandwidth Question

[Metzler, David]

Title: Message

I have heard the same rumor, but have often wondered whether it's one of those marketing simplifications.   I may be wrong, and if so would love to be corrected, but I think a better statement would be that because of the time division involved in using the same frequency for different speed connections, the slow links use a disproportionate amount of the bandwidth that is available to the access point and the client.    Speaking strickly theoretically, a 1KByte/sec file transfer on a 1M link will take 11KB of bandwith from the device connected via an 11M link, and 50K of bandwith from the client at the 50M link.   Put another way, at 50% utilization of the 1M link, you will still be using 50% of the 11M link.   So yes an active 1M device can be disasterous to your new 802.11g network performance, but I dont' think a passively associated device affects your transfer speed to your high bandwidth device .   I might try to verify this by manually configuring a 350 client to only nego so I'll let you know what I find out.   Even if I am wrong, this is as good as gets from the physical limitations of shared media.   David Metzler Network Services The Evergreen State College 360-867-6728 [EMAIL PROTECTED] http://www.evergreen.edu/netservices     -----Original Message----- From: Eric T.
