RE: [WIRELESS-LAN] Betr.: [WIRELESS-LAN] Gigabit Wi-Fi
You got it right Lee. The higher speeds will not necessarily be of use for us in the higher ed sector (yet... you never know), although it will be nice to simply have the capability in those special cases where they could be used. For now the one advantage that Gigabit Wi-Fi will provide will be improved HD video streaming. Again, you could see this mainly as a consumer-oriented advantage rather than an enterprise. But we are seeing more and more devices with wireless network capabilities these days. I think these new standards will be the answer to the growth of all these upcoming WiFi-enabled devices.

I can't find the direct quote. I can find the mission statement that is directly related to it: http://www.google.com/fiber/kansascity/about.html But a project manager invovled with the Google Fiber Project (Gigabit access to the home in Kansas City) had a quote along the lines of: When everyone had a modem, and only accessed email and basic webpages, nobody could imagine downloading a movie, and video conferencing (Skyping). Now this is commonplace. We don't know what people will do with larger bandwidth, because it's never been available. I think of this quote every time someone start talking about connection speeds (Be it Wireless, Wired, and Consumer Connections) Mike On Wed, Jan 11, 2012 at 9:44 AM, Hector J Rios hr...@lsu.edu wrote: You got it right Lee.

With the amount of glasses free HD 3D screens being shown at CES this week, I would imagine something along the lines of Skype in HD 3D. Also, the next HD standard will be 4k HD. That will exceed the limits of current 802.11n. Think of it this way, HDMI version 1.4 cables are capable of 10Gbps. People are going to want that without the wires (eventually). Can you imagine the day when all you have to do is hang that new TV on your wall and plug in the power? I can. And it will be amazing. Of course then there's wireless power. So maybe not even a power cable. :) Zach Jennings Senior Network Server Manager Aruba Certified Mobility Professional, Airheads MVP West Chester University of PA 610-436-1069 From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Mike King Sent: Wednesday, January 11, 2012 10:37 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] Betr.: [WIRELESS-LAN] Gigabit Wi-Fi I can't find the direct quote.

RE: [WIRELESS-LAN] Betr.: [WIRELESS-LAN] Gigabit Wi-Fi
The consumer market loves new technology, and since this standardizes on the 5GHz band only, it is my best friend. Most of the RF problems we have is because too many computers are perfectly happy working on N on the 2.4 GHz range, yet there are too many legacy devices and mobile devices to cut off that band. The freedom of having so many NON-OVERLAPPING channels to play with is GREAT! Having the high bandwidth overhead is wonderful, especially since wireless technology has a high loss overhead. Remember how many packets get transmitted that aren't actually payload. However they are increasing the amount of bandwidth by reducing the number of channels. This really screws enterprises, apartment complexes, and, well, anywhere with a high concentration of access points. Again, this is not the technology of the future. This will take us one step closer, but ultimately the channels and airwaves will saturate again before the next decade and we will be back to the drawing board again. We need more channels AND more bandwidth, not one or the other for it to be truly future-ready. -- Andy Voelker Manager of Student Computing in the Technology Commons Western Carolina University Be sure to check out the WCU TechTips Podcast at http://www.youtube.com/WesternCarolinaU!!

We have faculty that have students downloading a lot of information during class, so even in smaller 12-25 person classrooms, the added bandwidth means less time it getting the information, and more time spent teaching. I also suspect that Apple will adopt the new standard in their laptops and desktops, so there is the chance you'll see 802.11ac capable devices within the next 12 months, and given that Apple's student share here at my campus is now ~75%, that translates into a lot of 802.11ac capable devices.

Wide channels in 5 GHz for 11n are a safe bet- there is usually enough channels to burn 40 MHz without penalty. But 80 MHz and 160 MHz for 11ac 500 Mbps and Gig speeds?

However, I do love analogies... and to me, taking up two lanes on an existing highway to let one lane of traffic drive faster does seem somewhat shortsighted. My second point is related to Heath's excellent question: are these high speeds really necessary? At least on my campus, the drive for wireless is to give users reliable access to the Internet. Since we will not have enough bandwidth in the foreseeable future to have 802.11n WiFi be the bottleneck, I am quietly wondering how necessary this kind of upgrade would be for us.
