The Defense Department and technology companies struck a compromise last week to prevent interference with military radars from a new generation of wireless Internet devices.

The agreement effectively avoids traffic collisions in the invisible radio spectrum between high-speed Internet surfers and America’s soldiers.

Under the compromise, manufacturers agreed to build into future devices technology to detect and actively avoid interfering with military radars that operate on similar frequencies. The deal also specifies how sensitive that detection technology must be.

In exchange, defense officials will endorse U.S. proposals to nearly double the amount of lucrative wireless frequencies, which will permit more Internet traffic.
