FCC ALTERS AMATEUR 76-77 GHZ ALLOCATION
As proposed more than two years ago, the FCC now has adopted
rules to temporarily restrict amateur access to the 76 to 77 GHz
band. In exchange for the suspended spectrum, the FCC has
upgraded amateur status from secondary to coprimary in the 77.5
to 78 GHz band. The changes were among several the FCC adopted
July 6 to encourage commercial development and use of the
millimeter-wave frequencies above 40 GHz. The change at 76 to 77
GHz was to provide additional interference protection for vehicle
radar collision-avoidance systems expected to be operational in
that band.
The ARRL had opposed adoption of the temporary restriction at
76 to 77 GHz, saying it did not foresee any incompatibility
between the vehicle radar systems and amateur operation. The FCC
said it plans to revisit the possibility of spectrum sharing in
the band and encouraged the League to work with the auto industry
to develop a sharing plan.
The FCC said upgrading the status of the amateur and
amateur-satellite allocation at 77.5 to 78 GHz will ensure
amateur access to spectrum near 77 GHz "without the threat of
preemption by higher priority services." The Commission also said
it believes the allocation is necessary to foster amateur
experimentation using millimeter wave technology.
