Bosch, Seeking More Unlicensed Spectrum, Slams CTIA Concerns mmWave Group Backs

Bosch said CTIA makes no new arguments beyond what's in an FCC spectrum horizons high-band order on why the regulator shouldn't reverse its refusal to make available for U.S. unlicensed use the internationally harmonized 123-140 GHz. The company "seeks a single addition to, but no other modification" to the 2019 order. Other than 120-123 GHz, the rules didn't make such a big swath available, the automotive technology manufacturer replied to the association's opposition. The company said applications could include object detection; vehicle driver state sensors; gesture control and recognition for inside vehicles; home automation systems; and high-resolution obstacle detection for industrial robots in the millimeter-wave range. Also consider, here or separately and soon, OK'ing ultra-wideband device operation (see 1908190029) including around 122 GHz, the company asked in docket 18-21. The mmWave Coalition backed CTIA's concerns on not changing the "compromise path" of creating four unlicensed bands and an experimental license for above 95 GHz. "Bosch’s use of 'internationally harmonized spectrum'" apparently refers to longstanding ITU "general allocations for various radio services rather than services rules for more detailed use," said the coalition, which includes Global Foundries, Keysight Technologies, National Instruments, Nokia and NYU Wireless, in a filing posted Tuesday: "Create transparent rules for short range large bandwidth unlicensed sensors in spectrum above 95 GHz at much lower powers than the Commission authorized in the initial unlicensed bands." CTIA declined to comment now, beyond its Aug. 15 opposition.
