A question
Part 15 vs ISM
I thought there was NO protection within the ISM bands. No licensed
operations there.
Now, someone can get a license in the middle of an ISM and then force
the others out?
Don't sound kosher... But I want to know where to apply for one of
these. I can force everybody off 2.4GHz then... ;)
The Table of Frequency Allocations, which NTIA last released in August,
2011, summarizes who actually owns which piece of spectrum. A given
allocation is either government exclusive (thus primarily run by NTIA),
non-government exclusive (thus primarily run by FCC), or shared. NTIA,
however, does allow some government-exclusive frequencies to be shared,
and current law essentially requires them to open up a certain amount of
it to unlicensed use. Each sliver also has both primary and secondary
users; secondaries have to protect primaries.
The 5 GHz band (5150-5850) is divided into nine separate slivers.
Primary on 5650-5830 is government exclusive radiolocation (radar).
Amateur is secondary. Unlicensed and ISM are even lower on the pecking
order.

I'm going to ask the FCC Enforcement Bureau to reschedule the meeting
to June 25 (one week later) so WISPA's FCC Committee Chair (Alex
Phillips) and I (WISPA's FCC Committee Technical Consultant) can
attend. For any solution to be successful, we need more technical
information about how the radar actually operates. We also may be
able to apply some of the knowledge we gained when we addressed the
5.6 GHz Terminal Doppler Weather Radar interference situation a few
years ago. Hopefully the FCC will agree to our request. We expect
that a collaborative approach between the DoD, the FCC and the
unlicensed community, which as Scott pointed out is much larger than
just WISPs, will be the best and most successful approach.
