The following is from the briefing. It speaks to the advantage Cisco sees in the dual 5GHz radios.

My understanding is that the two 5ghz radios will have required channel separation to prevent NCI.

I’m looking forward to the 2800/3800 AP features as we deploy new infrastructure and high density WiFi. I hopeful the external antenna model can help reduce the # of APs/licenses needed in very high density locations. The auto channel width could be nice if it works okay in our environment. Only time and testing will tell….. Not sure if multi-gig will be a factor in the coming year but we are certainly looking at it for the new Cisco and new Aruba APs. Our Aruba folks indicate two 5.2 GHz radios in the same antenna location will not work efficiently…. So we’re hoping there is some software magic to overcome physics. Needless to say I’m trying to keep my expectations low in order to be pleasantly surprised. There are a couple “No Strings Attached Show” podcasts discussing 2800/3800 and flexible radio assignment. (sponsored podcast) There is also a “Cisco Champion Radio” podcast discussing 2800/3800 features. PS. We are looking at 1810w for dorm deployment. It’s wave2 AC but still does not do clean air if you need that.

Yes, the flexible radio design is definitely interesting. I’m interested to see how it plays out in terms of shuffling clients between APs based on what radio is available. I wanted to ask…have you considered the 702W for your res halls? It really seems to be the way to go in terms of creating small cells for the myriad devices that existing in that setting. We have a new dorm going up as well and with our experience with the 3502i’s, which grants has not been bad, but I really see the benefit of going with the 702w style. -dan Dan Brisson Network Engineer University of Vermont From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Jeffrey D.

For the Cisco shops: I recently had a briefing on the new Cisco 2800/3800 Wave 2 WAPs coming in May, and I’m pretty excited for the new flexible radio design. For those that have not read up on it, in the new models one of the two radios can dynamically move (self optimize) between 2.4 and 5 GHz depending on need (coverage/performance) or function (Serve clients, security monitoring, service assurance aka be a client, or enhanced location). Seems like Cisco is addressing one of my long standing concerns/wishes, that when designing dense deployments, that the number of 2.4 GHz radios become overkill and wasted. The new model provides for much better 5 GHz coverage (lots of WAPs running 5GHz x 2) with just enough running 2.4 GHz to handle legacy needs. It’s going to make my life much easier when designing for our residential halls. Any of the other Cisco shops excited for the new flexible radio feature? Thoughts? I have a new residence hall coming online in August so the timing is great.
