High-Stakes Race to Unlock a Wider Web

The nation's top technology companies have spent millions of dollars and nearly two years building devices, poring over laptops and working in federal labs trying to come up with a new way of providing high-speed Internet to bandwidth-hungry cities as well as hard-to-reach rural regions. Last week, the companies moved from lab to field. Engineers from the technology heavyweights, including Motorola and Philips, lugged their laptops, antennas and other equipment to parks, homes and high-rises around the Washington area, hoping to prove to the Federal Communications Commission that the unlicensed airwaves between television stations, known as white spaces, could provide a new form of mobile Internet service.
