Group of 25 companies reiterated call to FCC this week to reverse its certification of Time Domain ultra-wideband (UWB) communications product. Challengers, including American Airlines, Motorola and Qualcomm, asked Commission to reverse its grant of authorization and deny application for equipment authorization. Time Domain earlier this month opposed application for review, saying it had submitted data to FCC during equipment authorization process that showed there were "no unauthorized emissions emanating from the UWB device." In question is TAG device -- UWB signal generator designed mostly for use as research tool by equipment developers. It's composed of digital module and radiofrequency module. Time Domain said in opposition filing that it had submitted report from Intertek Testing Services as part of equipment application that "makes clear" that TAG device met FCC requirements. Lab test found there were no intentional emissions between 960 MHz and 3.1 GHz, Time Domain said: "The FCC's own laboratory called for a 'pre- grant' sample of the device and evaluated the product before the Commission issued the grant of equipment authorization. The application for certification and the accompanying evaluation have made clear that the TAG device complies fully with the recently promulgated UWB rules and with Part 15 rules in general." Challenge by 25 companies argued that FCC authorization would allow higher emissions from device in frequencies below 3.1 GHz than were permitted under UWB order adopted in Feb. Application for review took issue with filters in UWB device between circuitry that generated RF signal and antenna attached to unit. In filing opposing Time Domain request that FCC reject challenge, GPS, airline and wireless interests said Time Domain did not "directly respond" to 2 "critical inadequacies" in testing that they called into question: (1) That authorization grant should be reversed because Time Domain hadn't submitted data on filter characteristics on measured level of radiated emissions, "which are critical to assessing whether the device complies with the UWB limits." (2) That digital circuitry exception shouldn't apply unless all of device's components and software associated with UWB transmission function were removed or disabled before it was tested.
