The FCC's promised national broadband plan should have its formal unveiling on Tuesday, an early scoop of the details claimed on Saturday. Over the next 10 years, the agency would subsidize broadband Internet access for rural areas, creating a combination Internet and cable set-top box, and a previously hinted at plan to relicense as much as 500MHz of spectrum for wireless Internet access. Speed would be a critical focus as well, as the 100 Squared plan woube part of the proposal and promise 100Mbps Internet access to 100 million homes.
