Pete, The numbers I am providing here may be outdated since I am not currently involved in our daily operations. Our IPTV solution was already in place and is handled by a different group here on campus.
We are providing 15 channels of encrypted 720p IPTV to clients running Haivision's VideoFurnace InStream client. During our testing before deployment, we had 20+ clients spread across the 15 channels viewing simultaneously connected to one Aruba AP-125 AP. Since we deployed this in fall 2009, we have not had any complaints from our customer base due to the video streaming. We periodically experience congestion issues on our Internet connections, but that is unrelated to the video streaming. We started only offering the IPTV service on a 5GHZ 802.11n-only SSID. Eventually, we got complaints from users with 802.11b/g/n clients that wanted this service. We then expanded the offering to our normal 802.11 a/b/g/n SSID and retired the "high speed" SSID. Aruba's Dynamic Multicast Optimization technology is their "magic" We were involved during alpha & beta testing and were one of the first customers to deploy this to our customers. We worked directly with Aruba engineering to stress test this technology as it was being developed & refined. I can put together a conference call to talk about this more offline in detail, if you wish. We have been very impressed with Aruba's technology and support. No vendor is perfect and, many times, we are running our system on custom code testing solutions to bugs we have found. We are doing things with Aruba's technology that other wireless vendors said could not be done.

Bruce, Are you saying that you are providing HDTV channels to all their wide screen TV's in the rooms over wireless that is equivalent in quality to what they would get from satellite or standard CATV? I would be curious to hear what the quality of experience is for the students watching HDTV, and what the experience is like for those surfing the net, as well as the download speeds and stability and latency they experience.

Russ, I disagree regarding IPTV. We have been successfully running IPTV with our Aruba system for over two years. We started with a single 5 GHz 11n-only SSID, and then expanded to an 802.11a/b/g/n SSID. I expect Cisco has something similar. I think Lee Badman is one of the Cisco experts here.

We just finished rolling out wifi to all dorms. Each dorm is uniquely different in terms of age and/or construction materials. I used a variety of tools to determine placement of ap's. However, the first thing I did was place one or two AP's in area's that I thought would be strategic. I used Air Magnet to determine if the heat map would provide adequate coverage. I did a total of 16 dorms like this and ended up adding 12 additional AP's in area's that had little coverage. We installed a total of 424 Ap's and we added 12 more, not bad. That said, I still have a small percentage of users with 'wire only' devices. Not to mention the game consoles that are still wire only. That said, we will be building a new dorm next year. I plan on wifi only but will include wired ports as well. Granted, not the "port per pillow" we have been use to, but maybe "port per room". I haven't made a decision yet. Wireless is still half duplex and the best I can get out of 802.11n is 300mps. So, applications like IPTV, Digital Signage still require a wire. Not to mentioned fire alarms, HVAC. Phones, emergency notification...all things that we need to run a building, still require a wire. I have had as many as 20 clients on one AP, with no issues. However, as more bandwidth intensive apps are available (not to mention the increase in devices), I suspect I will have to limit this. So far, there has not been a need. I hope this is helpful to you!

Hello, I am looking for anyone who has moved to wireless only dorms. We have fast track dorm construction project that is starting and our CIO would like to make it wireless only. I am wondering if anyone has done this and if so what kind of advice or comments can you share. We will be using Cisco waps. Also I am wondering what kind of ratio you based your access points on, how many devises per person. Best Regards, Sara Sara M.
