Re: [WIRELESS-LAN] mixing 'b' and 'g'
We are doing that without any problem. We use Cisco 340, 350, and 1200 series APs (exclusively), though we are quickly getting rid of the 340/350 stuff. -jcw To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU From: James Savage [EMAIL PROTECTED] Date: Thu, 12 May 2005 16:18:55 -0400 Subject: [WIRELESS-LAN] mixing 'b' and 'g' Hi all, We're in position where we may be mixing 'b' and 'g' APs in areas where it's likely users will roam between them.

Re: [WIRELESS-LAN] mixing 'b' and 'g'
I am not a wireless network expert, but it is my understanding that a b connection to a WAP slows all traffic on that WAP to b speed. - Mike -- J.

Close. .11b is of course 11meg .11g goes to compatibility mode, and drops down to something in the order of 19meg. -Original Message- From: 802.11 wireless issues listserv [mailto:[EMAIL PROTECTED] On Behalf Of Mike Yohe Sent: Thursday, May 12, 2005 4:42 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] mixing 'b' and 'g' I am not a wireless network expert, but it is my understanding that a b connection to a WAP slows all traffic on that WAP to b speed. - Mike ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
RE: [WIRELESS-LAN] mixing 'b' and 'g'
We actually fix all our b at 11 - and our a/g cells at 48 and 54. Works like a charm... John J. Brassil | Network Engineer, Vanderbilt Data/Video Engineering voice 615.322.2496 -Original Message- From: 802.11 wireless issues listserv [mailto:[EMAIL PROTECTED] On Behalf Of Dave Molta Sent: Thursday, May 12, 2005 3:22 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] mixing 'b' and 'g' The performance degradation associated with mixing b and g on the network varies depending on the mix of b and g traffic. I believe our recent tests of b and g clients doing simultaneous file transfers through the same AP showed an aggregate TCP throughput of around 12 Mbps. That's about twice what you'd see on a b-only network and about half what you would see on a pure-G network with no protection. Things can get worse if you have lots of 11b clients associated at 1 Mbps because they use more bandwidth to get their work done. Some organizations don't allow 11b associations at anything lower than 5.5 Mbps. dm -Original Message- From: 802.11 wireless issues listserv [mailto:WIRELESS- [EMAIL PROTECTED] On Behalf Of Mike Yohe Sent: Thursday, May 12, 2005 4:42 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] mixing 'b' and 'g' I am not a wireless network expert, but it is my understanding that a b connection to a WAP slows all traffic on that WAP to b speed. - Mike -- J.
