Super Wi-Fi transmitted via White Spaces

WOW!! I was just reading the Digital Education blog @ Education Week when I learned about Super Wi-Fi and White Spaces.  There I was . . . innocently reading their posting on how the FCC Approves E-Rate Changes . . .

When BAM, I am hit with new terms that I had not before known - Super WiFi and White Spaces.  Following the learning process that we all follow, I quickly did a Google search to find out more about these two entities.

Turns out that at the Tested blog, they had an article entitled FCC Opens White Space Spectrum for Super Wi-Fi where I learned about this new opportunity for WiFi. Turns out that the FCC ruled on 9/23/10 that they would open up an empty portion of the radio wave spectrum between TV and broadcast stations.  This "White Space" would be used for "Super WiFi."  Apparently, WiFi has been operating on a "Junk Band" since its inception and the white space will bring about a massive increase in broadcast range.


16 TIMES!!!!

One article that I read said that the Super WiFi could travel as much as 16 times further than our existing WiFi.  Presently the 802.11n routers will adequately carry a signal 100 meters. The Super WiFi is purported to have a range 16X that of our standard routers.  That means that these could have a distance of 1600 meters (= 5249.343832020997 feet) or almost 1 mile.  Imagine that!!! You could have a Super WiFi system that would range 1 mile from its source.  That means that there would be a circle with a radius of 1 mile.   Obviously there can be confounding variables like buildings and trees and ??, but the possibility is dumbfounding.

What could your school district do with routers that have a 1-mile range?  Think of the homes we could supply with Internet access so that students who li can't afford broadband will be able to do homework when they take home their laptops from their school.

Don't you just LOVE progress??????

What are your thoughts or experiences or visions about this?

  1. BINGO!!!! Remember my blog about Real Global Collaborative Learning Still a stone throw away? You just gave me a superb feedback!!!!! I think the problem with the physical wired network is the manual labor involved. The resources that go into it in terms of material and land are a hindrance too. We do not have to "construct" the space that WIFI signal pass through!!!!!! Just imagine, if the router are erected high enough with less destruction between the router and the users, a whole city could be connected by a couple of routers. Just as you mentioned, that would eliminate the sky high monthly charges by the internet providers. This means more people connected for less and more kids connected to the world for more collaborative learning.

  2. This is nothing short of amazing! I'm guessing problems schools have with the one-to-one laptop initiative is that students still may not have internet at home - but putting this into play completely eliminates that problem. Like Evans said, just put a few routers in different places in the city - and there you are, every student has the internet. Making homework assignments more meaningful and fun! I am so excited to see this happen. Any word on when this will be ready for the public?

  3. Glad you see the possibilities, Libby. I don't know when Super Wifi will begin. Probably not for a while considering how government works.

    I tried to find it on the web but to no avail. If you find out, please post it here. Anyone else know?
