Now that the B and C blocks of the spectrum has been allotted by the FCC things are set-ready-go to open mobile broadband U.S. networks, broadband IR, and, yes, to a whole new hacking space. It’s a matter of time. The C Block hacking competition is coming. Never ignore what can be done with such new playground.
I wonder how the FCC is going to enforce regulations on the 22-MHz portion of the spectrum, already handled to Verizon. http://www.pcworld.com/article/id,143705-c,industrynews/article.html
Meanwhile, IR research centered around open broadband networks are needed, so as search engines.
