Microsoft researchers tested a new
protocol, called White Fi, using the
device shown here.
Microsoft with researchers from Harvard University have developed a breakthrough technology which allow using of “whitespace” spectrum for wireless broadband networking. White spaces’re the portions of the unlicensed spectrum that’s between the parts previously used to broadcast analog TV channels. By tapping into these lower frequencies, it should be easier to provide broadband Internet access in rural areas and fill in gaps in city Wi-Fi networks. For e.g., the spectrum between 512 megahertz and 698 megahertz, which was originally allotted to analog TV channels from 21 to 51, offers a longer range than conventional Wi-Fi, which operates at 2.4 gigahertz. "Imagine the potential if you could connect to your home [Internet] router from up to a mile," says Ranveer Chandra. Chandra and his colleagues designed a set of protocols, which they call "White Fi," to successfully navigate the tricky regulatory and technical obstacles involved with using white spaces.
