The Pentagon announced over the weekend it reached a compromise with the wireless industry that clears the way for increasing the amount of spectrum for Wi-Fi-related products. In exchange for getting the Pentagon to drop its objections to sharing space with unlicensed products, the wireless industry agreed to install technology in future devices that will detect and avoid interference with military radar installations.

In December of last year, the Federal Communications Commission (FCC) began proceedings that could ultimately result in doubling the available spectrum for high-speed wireless local networks. Although it had yet to show that Wi-Fi devices interfered with military devices, the Department of Defense feared the low-powered, unlicensed emissions might possibly interfere with up to 10 types of radar operated by the Pentagon.

The FCC proposal, which could take up to year for approval, would permit unlicensed transmitters to operate in additional frequencies below 900 MHz and in the 3 GHz band. Known as Wi-Fi or 802.11, wireless networks provide connectivity up to approximately 300 feet and are considered ideal for home and office use. Last year, the popularity of these networks showed strong growth and, in turn, demand for spectrum space for the networks has increased.
