including GPS, we believe that the GPSIC’s continuing demands for unrealistically low UWB emission limits in the GPS band has been an obstacle to resolution of this proceeding,” Xtreme CEO Martin Rofheart said: “After 3 years, 7 studies and more than 700 filings, it is time to bring the proceeding to a speedy conclusion so that consumers and the economy can benefit from the wireless communications capabilities of ultra-wideband technology.” XtremeSpectrum told FCC that GPSIC had disputed its engineering analysis on interference concerns with UWB and had argued for lower emission limits in GPS band. Letter said company continued to stand behind its original analyses and said “no additional protection is needed.” But it added: “In the interest of a prompt resolution, XtremeSpectrum will not object to emissions limits in the GPS band consistent with those demanded by the GPSIC.” They would include limits that were 35 dB below certain levels of Part 15 and additional 10 dB suppression of spectral lines as measured with 10 kHz resolution bandwidth. Company stressed it was adopting position only to speed resolution of UWB proceeding. GPSIC had contended Xtreme’s proposed GPS-band limit of 18 dB below Part 15 levels was too high, urging that UWB emissions be held to 35 dB below Part 15 limits instead. That level would meet worst-case scenarios outlined by GPSIC in its analysis, Xtreme said. “Solely to take the issue of GPS emissions limits out of contention, XtremeSpectrum will cede to the GPSIC’s demands,” XtremeSpectrum wrote. Company said it wouldn’t object to limits in GPS bands at 35 dB below Part 15 limits, plus additional 10 dB suppression of spectral lines. XtremeSpectrum also reiterated its support for indoor-only restriction for UWB and modified test for peak-to- average ratio. Xtreme said it would back any of 4 options now before FCC -- GPSIC’s proposed limits, earlier Xtreme proposal of 18 dB, original FCC proposal for 12 dB below Part 15 and recent request from Time Domain for Part 15 limits to be in effect across spectrum. “XtremeSpectrum emphasizes that it does not seek restrictive rules to hinder other manufacturers,” letter said. “We are eager to compete in the marketplace, not the Commission hallways.”
