New FCC proposed rule may exempt Part 15 'Damped Wave' emitters
The FCC has issued a Notice of Proposed Rule Making (NPRM) with an exception
to the longstanding prohibition against 'Damped Wave Emissions' as part of a
new class of "Ultra-Wideband Transmission Systems" (UWB) operating at
bandwidths exceeding 1 GHz or even 10 GHz. The FCC may allow these
"DC-to-Blue-Light" emitters under a modified Part 15, or it may open a new
Rule part to deal with UWB systems.
The closing date for comments is 07 DEC 98.
