That is worth mentioning: I'll be disappointed if this petition is limited to AirPlay. The real target here is Bonjour. It's required for an iOS device to use wifi to sync to iTunes. Time Capsule uses it. It is rapidly becoming the cornerstone of Apple's networking story. In fairness, if we give A

Re: [WIRELESS-LAN] 4-channels in 2.4 GHz

I looked into this about 18 months ago for our campus. It never made it to the point of a trial: I learned enough to stop the project before it made it that far, and I think I can summarize here what I found. I'll start by going back to basics: we all know that wireless channels overlap. A graph o

Re: [WIRELESS-LAN] Very high number of wireless devices returning from break

It's possible that since you are on a new version of the software, and the current numbers have been verified, that the old version of the software was under-reporting. But more likely it's a real increase. I could be new toys for Christmas, and it could be the old software didn't work as well for

Re: [WIRELESS-LAN] You knew it was coming...Airplay/Apple TV support for instructors.

York College is installing an AppleTV in every networked classroom over the next year. This is in support of a 1:1 iPod Touch program we use. We're tiny relative to U of Iowa, but if any of this helps, here's how we're making it happen: Classroom buildings are set so that users in the same build

Re: [WIRELESS-LAN] Access points with very low performance when multiple users connect their computers at the same time.

Your problem is probably air time density. The issue is that you only have 3 non-overlapping channels to work with in the 2.4Ghz space, most users won't have 5Ghz-capable laptops, each channel only supports about 25 clients from a practical standpoint, each access point is likely only listening on

Re: [WIRELESS-LAN] Disappointing numbers of 5ghz clients

There was another thread on this same listserv -a month or two back basically complaining about the lack of consumer laptops with 5ghz radios. When your average student or parent goes to buy a laptop for college, pretty much everything they see is still 2.4Ghz. Even if they're looking for 5Ghz (an

Re: [WIRELESS-LAN] Wireless in dorms

That Altitude 4511 product looked interesting. I'm curious to know the per-unit price on those, as quick google and amazon searches didn't bring anything up in that regard. I'd also like to see one with a pass-through port, so I can put one over an existing port in a student's room or classroom and

Re: [WIRELESS-LAN] Alternative POE injector for Ubiquiti wireless gear

A quick check on Amazon shows they list for a mere $17 each: http://www.amazon.com/Ubiquiti-POE-24-Power-Over-Ethernet/dp/B004EFHN66/ref=sr_1_8?ie=UTF8&qid=1311170318&sr=8-8 At that price, your solution might just be to get a stock of them so you can switch them out quickly, and keep RMAing them.

Re: [WIRELESS-LAN] iOS devices on wireless

The issue here is that students are here to do academic work, and the network needs to support that first. But I think that while they are doing that academic work they are still... here. This is their home, and we can't forget that. If it were just another corporate network we would do things li
