While most of the world was watched Barack Obama make history on Tuesday, the Federal Communications Commission quietly voted for its own little revolution.
Despite furious lobbying by TV broadcasters, Broadway producers, Dolly Parton and rock band roadies everywhere, the panel approved a plan to open up the so-called “white spaces” between television channels for unlicensed wireless gadgets.
Back in the dawn of television, the government left these little gaps in the TV spectrum because broadcast TV stations were so powerful – and the available technology was so limited – that engineers feared the stations would step on each others’ signals if they were too close together.
That issue became less important as equipment improved over the years, and it will change even more with the switch from analog broadcasting to a more efficient and precise digital system in February. For more about that, read my DTV Transition Q&A page.
A coalition of major industry players, including Google, Intel, Microsoft and Motorola, backed the plan, which they see opening up a whole new market for wireless Internet access. Because these white spaces are smack in the middle of the TV spectrum, signals in can travel considerable distances, opening up the possibility for relatively cheap, high-speed wireless Internet service in rural areas.
But TV broadcasters are still worried about newcomers with faulty equipment or intentions interfering with their frequencies, and the people who produce plays and concerts are furious. That’s because the wireless microphones they use every day use those very same frequencies. After an acrimonious battle and repeated tests by FCC l aboratories and a lobbying appeal by country legend Dolly Parton. She conceded that she knows nothing about the technology, but does know a thing or two about how important wireless mics are for musicians in concert. They’re the reason singers can prance all over the stage without worrying about tripping over a cord, and why Broadway musical stars don’t need penetrating “Broadway” voices any more.
In an attempt to pacify the theater and concert producers, the FCC is requiring manufacturers of equipment to set of databases with locations where wireless microphones are typically used, as well as sensors for wireless microphone transmissions. The theory: with current technology, the new wireless devices can avoid frequencies that are being used and switch to unoccupied channels.
With deep pockets on both sides, this isn’t likely to be the end of the issue. Here are good explanations from USA Today and the Washington Post.
