FCC Invites Public Comment on 10-10.5 GHz Petition

FCC SealThe ARRL report the FCC has invited public comment on a Petition for Rule Making (RM-11715) that would make a significant portion of the 10.0 to 10.5 GHz band available for wireless broadband services.

The Petition by Mimosa Networks Inc proposes a band plan for 10.0 to 10.5 GHz that, it says, would protect frequencies most often used by radio amateurs. The petition hinges on FCC adoption of rule changes that would put the 10 GHz band under Subpart Z of the Commission’s Part 90 rules. Subpart Z currently sets out regulations governing wireless licensing, technical standards, and operational standards in the 3650 to 3700 MHz band.

“The application of the coordination procedures and requirements provided in Subpart Z will ensure that Amateur Radio operations in the band will not be disrupted,” Mimosa told the FCC. “In addition, as a further safeguard, Mimosa proposes a band plan for the 10.0-10.5 GHz band that would protect frequencies in the band that are most often used by Amateur Radio operators.” The proposed band plan would specify 10.350 to 10.370 GHz as an “Amateur Calling Band,” and 10.450 to 10.500 GHz for Amateur-Satellite operations in the midst of 21 wireless broadband channels and a small guard band.

ARRL Chief Executive Officer David Sumner, K1ZZ, is quoted as saying “Mimosa’s proposed power limit of 55 dBW EIRP is very high, particularly for point-to-multipoint operations, and no mechanism has been proposed for ensuring that harmful interference to amateur operations does not occur.”
