After a series of unsuccessful tests, the Federal Communications Commission is heading back to the lab to assess a new round of devices for broadcasting high-speed Internet in the white space available in between TV airwaves. The prototypes come from a coalition of top-tier bidders, including Microsoft, Philips, and Intel, none of which received positive grades the first time around, the AP reports.
The coalition maintains using untapped airwave spaces would help them provide high-speed and low-cost Internet service, particularly in rural regions with limited access. But so far, no one has managed to produce a device that detects, but doesn't interfere with, TV programming signals outside of the laboratory. Round two of testing will take three months, with a report following six weeks later.
