The FCC dismissed a petition by the Satellite Industry Assn. (SIA) Thurs. to require radar detectors to comply with a 500 micro volt limit within Ka-band downlink frequencies at 18.3-18.8 GHz and 19.7-20.2 GHz. In its May 28, 2003,…

petition, the SIA asserted that in light of the then- impending launch of several Ka-band birds, the adoption of proposed emissions limits for radar detectors would “forestall even the possibility” that detector operations would interfere with new Ka- services. SIA said that without imposition of limits, emissions would cause interference in much the same way radar detectors previously did in the Ku- band 11.7-12.2 GHz. The Commission told SIA it took the steps to ameliorate any potential harmful interference caused by radar detectors in Ku-. The need for action arose because manufacturers operating in the 10.525 GHz band chose to employ local oscillators operating in the nearby 11.7-12.2 GHz Ku-band. Police radar bands are 10.525 GHz, the 24.150 GHz and the 34.700 GHz. Unlike the case with Ku-, Ka-bands are not located in close proximity to the 18.3-18.8 GHz and 19.7-20.2 GHz bands used by Ka- satellites. The Commission also said no information was presented that suggests detectors currently employ local oscillators in the Ka-band nor does the worry exist that any other harmful emissions are significant.
