FCC moves to unleash UWB technology
WASHINGTON — One year after giving the technology tentative approval, the Federal Communications Commission moved Thursday (Feb. 13) to clarify its rules on the deployment of ultra-wideband (UWB) technology. New products based on the technology are expected to arrive soon, regulators and industry executives said.

The action clarifies earlier rules that restricted the use of image devices used primarily for applications like bridge and road inspections. Manufacturers had complained last year to regulators and lawmakers that the rules as written would put them out of business.

Other changes in current UWB rules were minor, and the agency said it was reluctant to make significant changes to UWB technical rules until it has more data on the operation of UWB devices. A key issue will be whether UWB devices used for applications ranging from radar imaging to short-range, high-speed data transmission will interfere with other systems.

The Pentagon and the Federal Aviation Administration are particularly wary of UWB, warning that the systems could interfere with air traffic control, command and control systems and even missile guidance. UWB proponents said most interference problems have been solved.

The FCC's said its order granted those operator requests that would not increase "the interference potential of UWB devices" while denying requests that sought further restrictions on UWB operations. As a result, UWB devices are expected to hit the market in the next 12 to 18 months, the FCC said.

UWB manufacturers praised the action, saying it would speed commercialization of their products.
