Re: [WIRELESS-LAN] Cisco 11n users
When I went looking for midspans back in June/July, there was only one that actually supported the required Cisco signaling to enable high-power mode on the AP. The midspan is/was the PhiHong POE125U-4HP four port unit. The other midspans required a dongle at the AP to split the power back off for input into the AP's power jack. PhiHong is the OEM behind Cisco's single-port injector for the AP1252, and I believe the 4-port is also coming soon under a Cisco label. best, Jeff Tim Cantin [EMAIL PROTECTED] 11/14/08 8:10 AM Midspans have been available for several months now -- when were you looking?

RE: [WIRELESS-LAN] Cisco 11n users
As far as the range is concerned we do get a greater range with the 1252's. I can't say we use this as a feature, because we didn't have a lot of wireless deployed before. Where we did have it deployed before we have put in more access points to do a capacity model rather than a coverage model. Where I have seen this range improve is I'm working on our Football stadium. In the press box we have a 1242 with a 12dbi 2.4 ghz antenna on one end and a 1242 with a Cisco 2506 (5dbi 2.4 ghz) antenna on the other end. The pressbox is sheetmetal all around it, so in the middle of the 40 ft building we were getting very little signal. So we mounted a 1252 inside in the middle, and we saw the signal just as strong across the field from the 1252 as we do the 1242's. My high watermark on clients is 685. I have seen as many as 65 N clients online. My displeasure with the 1252's are the following: 1. The DOA's. We have had about a 3% failure rate out of the box. This is either the ap or the POE injector. So getting them replaced under Cisco's 1 year limited warranty has been difficult at times. 2. We have to walk out to 1 to 2 of them a week and reboot them, as there weren't any managed solutions that we could afford at the time. The E class switches were just announced, but not released. That and they are too expensive for us. 3. The POE injectors do get pretty warm. When on edge we can fit 9 across on a 19 rack shelf. We originally tied them together to make a solid brick. This made them so hot you can hardly hold on to them. We have since stopped doing this. Give them air flow to stay cooler. -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Jeffrey Sessler Sent: Tuesday, November 11, 2008 4:09 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 11n users We are running 11n in 2.4 GHz on the 1252's, but only at 20MHz. 40MHz in 2.4 MHz seems like a very bad idea because of the lack of non-overlapping channels.

Re: [WIRELESS-LAN] Cisco 11n users
A lot depends on what kind of construction your building is -- brick, concrete and concrete block is entirely different from drywall and open spaces. The other aspect is your definition of full coverage. If you want the location functionality to work, you need much higher density and different placement of APs than just for basic data access. Also, support for VoIP requires higher density and disabling lower data rates. Any spaces with high user populations also may need a lot more APs than just range would indicate. In our environment the 2000 ft^2 is a bit optimistic. -- Toivo Voll Network Administrator Information Technology Communications University of South Florida On Wed, Nov 12, 2008 at 1:05 PM, Greg Gardner [EMAIL PROTECTED] wrote: On that topic, has anyone taken a look at how many AP's they deployed on a sq ft basis in your environment?

RE: [WIRELESS-LAN] Cisco 11n users
Hi Greg- The square-footage models scare me, quite frankly. Rather than a one-size-fits all WAG based on footage, we've come to trust both Ekahau and AirMagnet planning tools for budgetary planning- takes a bit of time to get your attenuation sources right, but the final guestimate ends up a lot more based in reality.

Re: [WIRELESS-LAN] Cisco 11n users
Hi, I would be very interested if this subject discussion was kept open to the group. We just turned on an 11a/b/g/n service using a single Cisco 4402 with 16 APs (soon to expand to the max 50 APs a single 4402 will allow. It covers a residence, so it's not a high density area nor would I expect a lot of roaming between APs. We're running Ciscos V5.1 of code while I understand that most folks are at 4.3? No negative reports (yet?) but we do have folks using it. This is our first stab at thin APs.we have 800+ 350s and 1121s. I'll be happy to try to answer any questionswe're still sort of new at this.thx.JJames SavageYork UniversitySenior Communications Tech.108 Steacie Building[EMAIL PROTECTED]4700 Keele Streetph: 416-736-2100 ext. 22605Toronto, Ontariofax: 416-736-5701M3J 1P3, CANADA ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] Cisco 11n users
Five 4404 with 230 1252s deployed (all have 2.4 5 radios) with the goal of reaching 350+ in January. Running Cisco's 5.1 code base. 5GHz running with 40Mhz wide channels. We went live September 1st with the bulk of the 1252s deployed in our residential halls. So far, I'd say that the deployment has been rather uneventful. All are in the same mobility group, and our peak concurrent user count is in the 800-830 range. We had some initial pains with Macs that employ broadcom-based airport cards where they would fall on their face if the AP was using channels between 52-140. We've simply disabled those channels while Apple and Cisco figure out what's up. best, jeff Lee H Badman [EMAIL PROTECTED] 11/11/2008 9:49 AM Wondering if anyone has jumped in to Cisco 11n yet on any sort of scale that they wouldn't mind sharing?

RE: [WIRELESS-LAN] Cisco 11n users
To extend Matt's question- how many are using 11n's extended range as a feature? What I mean is that we have most (though not all) of our designs based more on capacity than range. Even though 11n can give better range, not sure how important that will be when we still want less users on APs to preserve higher per-user throughputs. Though in some areas the better range will come into play and provide value, but these (for us) will arguably be in the minority. -Lee -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Barber, Matt Sent: Tuesday, November 11, 2008 3:07 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 11n users Anyone running 11n in the 2.4 GHz on the 1252s? 20 or 40MHz?

RE: [WIRELESS-LAN] Cisco 11n users
Do people deploying the 1252s find that 802.11a and 802.11g clients are getting better range and/or throughput? I understand that MIMO and MRC will improve the AP's receive sensitivity, making clients more visible, but I was curious whether this would apply to the downstream as well as the upstream. Cisco is targeting Transmit Beam Forming (an 802.11n optional feature) for Legacy Clients in a future release of code. --Bruce -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[EMAIL PROTECTED] On Behalf Of Jeffrey Sessler Sent: Tuesday, November 11, 2008 2:40 PM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Cisco 11n users Five 4404 with 230 1252s deployed (all have 2.4 5 radios) with the goal of reaching 350+ in January.

We had some initial pains with Macs that employ broadcom-based airport cards where they would fall on their face if the AP was using channels between 52-140.

RE: [WIRELESS-LAN] Cisco 11n users
What transmit power are people being using on the 1252 2.4 and 5GHz .11n radios? Are you stepping down the power to reduce the increased range effect?

Re: [WIRELESS-LAN] Cisco 11n users
We are running 11n in 2.4 GHz on the 1252's, but only at 20MHz. 40MHz in 2.4 MHz seems like a very bad idea because of the lack of non-overlapping channels. As for range, the building I'm in is a thick concrete/rebar construction and I can get about 120 feet (exiting the building) from an 1252 AP before I can't see it. That said, I'm designing based on capacity more than range. In the case that capacity is not an issue, I'm shooting for 50-70 foot spacing between 1252s to maximize 5GHz coverage.
