ARRL: No Need to Relocate Ham Band for Vehicular Radar



The ARRL has told the FCC there is no need to modify the current amateur radio allocation at 77-81 GHz in order to accommodate expanded spectrum space for vehicular radar, and notes that neither the original petitioner nor any of the commenters have made such a request. In comments on an FCC proposal to expand the vehicular radar allocation from its current 76-77 GHz to include 78-81 GHz, the ARRL says it has worked closely with petitioner Robert Bosch, LLC, and that both groups are satisfied that vehicular radar and amateur radio can "play nicely together" on the band, according to an ARRL bulletin.
 
Acknowledging the possibility that the Commission may choose to reallocate the 4-millimeter ham band despite its protests, the ARRL requested the assignment of "equivalent spectrum" at 75.5-76 GHz and 81-81.5 GHz. The current amateur allocation at 4 mm is 77-81 GHz, with primary status in the 77.5-78-GHz segment.
