Likely No Interference Between AWS-1 and AWS-3 Bands
(1 update - see below)
The FCC has released a report with its conclusions on the likelihood of significant interference between devices operating in the AWS-1 band (receive segment - 2.110 - 2.155 GHz) from operations in the proposed AWS-3 (2.155-2.175 GHz) band.
As I read the report (PDF) - the FCC engineers concluded "no big deal".
To me, this kind of thing is simple, cut, and dried. The parameters of the spectrum allocations are well-established. If adjacent services and systems "intrude" or "splatter" their signals outside their allocated spectrum, then they get shut down by the FCC. That's the entire point of licensed spectrum - the FCC plays referee, judge, and jury.
This helps answer at least some of the technological uncertainty about M2Z's proposal for a nationwide, "free" Broadband Wireless Internet Access (BWIA) system, though questions about the underlying economics, operation / business model remain.
Amusingly, I saw a fair amount of confusion about this story in the general news, that this report was about the recent White Spaces (license-exempt use of vacant portions of television broadcast spectrum) testing that has been conducted by the FCC.
Administrivia note - I'm trying out the use of excerpts in the RSS feed (which will ripple through to the email notification provided by FeedBlitz). Comments pro, or con, will help decide whether I continue to do so.
Update: John Murrell of Good Morning Silicon Valley says it oh so well in this delicious headline, and does justice to the story:
