Obama won the election, but for technology, in the short run at least, the even bigger voting news was that the FCC, by a vote of five to zero, had unanimously approved the conditional unlicensed use of white-space television spectrum.
White space, the 700-MHz spectrum that’s being freed up as TV channels switch from fat analog signals to thinner digital transmissions, has the potential to be used for many important uses. As Larry Page, co-founder of Google, wrote, “We will soon have “Wi-Fi on steroids” since these spectrum signals have much longer range than today’s Wi-Fi technology and broadband access can be spread using fewer base stations resulting in better coverage at lower cost.”
This is more though than just Wi-Fi on steroids. This is the opening of a new era of broadband. Today, most of us at home use either cable, DSL or, God help us, modems to connect with the Internet. Cable can be fast, but its speed is cut by the number of subscribers on any given line. DSL delivers OK performance, and as for modems, the less said the better.
Even as its best, cable at about 20Mbps, though today’s Internet demands even more bandwidth. It’s not just file-sharing with BitTorrent and the like that’s grabbing bandwidth. We’re moving to IPTV (Internet Protocol Television) with devices like the Apple TV, Netflix Player, and TiVo. Even the fastest Internet connections are stressed by 720p HDTV for these devices, and with 1080p HDTV just around the corner, our last mile bandwidth infrastructure simply isn’t up to the challenge.
