(UWB) Rules For Potential New Outdoor Applications Proposed Restrictions on Pulse Repetition Frequency “Unnecessary”
The Commerce Department’s National Telecommunications and Information Administration (NTIA) supports the adoption of current Federal Communications Commission (FCC) ultrawideband emission limits for all outdoor device applications and believes that restrictions on the pulse repetition frequency are unnecessary as long as the current emission limits for handheld devices are met, according to NTIA comments on the FCC’s Further Notice of Proposed Rulemaking on UWB. “We support the FCC’s clarification of the UWB rules so that this new industry sector can take hold and grow while we protect critical federal systems from harmful interference,” said Acting Assistant Secretary of Commerce Michael D. Gallagher. “The rules adopted by the Commission in its first Report and Order successfully strike that balance, and provide a stable platform for development of new devices that will save lives, boost U.S. productivity and enrich the experience of U.S. consumers.” NTIA’s filing also includes analysis of pulsed “frequency hopping” vehicular radar systems operating in the 22-29 GHz frequency range. NTIA finds no greater interference to government passive sensing satellites than is presently permitted for impulse UWB vehicular radar sytems, but noted that its conclusions do not apply to UWB “frequency hopping” systems in other bands. In its comments, NTIA also proposes a compliance measurement procedure for pulsed “frequency hopping” vehicular radar systems. One FCC proposal that the NTIA filing does not support is the elimination of the minimum bandwidth requirement from the definition of a UWB transmitter. According to the comments, removing the minimum bandwidth requirement could allow unlicensed non-UWB operations in restricted bands.
