Wireless provider Sprint Nextel has announced that it has completed its five-year, USD750 million project to clear wireless spectrum for the government’s national broadband internet plan. The work was completed across the US and Puerto Rico, culminating in Anchorage, Alaska, which was the last of the 213 markets affected. According to Sprint, its aging microwave technology has now been replaced with more than 100,000 pieces of high-performance equipment designed to function efficiently with less spectrum. The process reportedly cleared 35MHz of spectrum, as part of President Barack Obama’s goal of freeing up 500MHz of wireless broadband spectrum.
