Yes, add that to the spectrum list. At least in Sprint's case. They own
most of the BRS/EBS licenses and leases, and are using it for their LTE.
A few others are there too, on a more local basis. Nextel had some iDEN
frequencies in the 900 MHz range and that too is in Sprint's network
now, but those were IIRC only 3 MHz channels, so mostly good for voice
coverage. Sprint still can't hold a candle to the big two in that
regard, though, and even T-M is ahead now with its 700 MHz coverage.
AT&T holds a lot of the 2300 MHz WCS licenses. I think one of the
Nextwaves held some and was leasing them to WISPs, but AT&T bought them.
Verizon of course had bought a previous Nextwave.

We are involved in this band, at WinnForum. That's where the standards
are being written. The FCC announced the rules last year and did a
minor update of them earlier this year. Now we're working with
WinnForum to fix an oversight that makes the band pretty much unusable
by rural WISPs. ("What, your installers don't carry a sat phone?") We
expect to make progress, though.
The name Citizens Broadband Radio Service is really unfortunate. Press
articles about the CBRS Alliance are making jokes about
"breaker-breaker good buddy", and the article that Gino pointed to had
a picture of a President Washington CB transceiver. This band has
nothing to do with CB and doesn't work a bit like it. The only thing
close to CB is that its rules were assigned to a new Part 96, while CB
itself is Part 95 of 47 C.F.R. (the FCC rules). It probably should
have gotten a Part number in the 20s, though, down by cellular.
The FCC rules are by design technology-agnostic. The CBRS alliance
looks like a pro-LTE group. LTE is going to be the dominant
technology, and some companies think LTE will totally dominate the
band, but some of our vendor members have other uses for CBRS.
Existing 3650-3700 MHz is being merged into CBRS, of course, which is
what led to its being frozen in April 2015. Some WiMAX equipment could
be upgraded, for instance, to be compliant. WinnForum has a
Coexistence Task Group working on ways to mitigate interference
between dissimilar technologies.
The big carriers are looking at this for "small cells", essentially a
way to add spectrum capacity relatively cheaply so they can sell more
gigabytes of cat videos to smartphone users. Assuming we fix the
glitch in the rules, this will also be a useful WISP band, especially
in rural areas where the big boys don't need additional capacity.
After all, they already have 700 MHz, 800 MHz (original cellular A&B),
1900 MHz PCS, 1700 MHz AWS-1, and soon 600 MHz if the Incentive
Auction now under way is successful at buying out TV licenses. In the
city, all those cat videos are clogging existing spectrum, but
elsewhere CBRS is likely to be their fourth or fifth choice.
Licensing is complex. As you probably know, there are "incumbents"
(includes currently-registered 3650 licenses), PALs, and GAA
("licensed by right" as a variant of unlicensed). PAL merely grants
priority over GAA in the Spectrum Authorization System; it doesn't
block off any frequencies. Rumor has it that one of the very big
national carriers plans to go all-GAA themselves. Since the license
area is a Census Tract, a PAL might be quite affordable for a rural
WISP, if you think it's worthwhile.
But making matters more complex is the need to protect fixed satellite
earth stations, as low as 3600 MHz. Plus the need to protect naval
radar, the band's primary owner. So the SASs will require radar
detectors (ESC) in the field before anyone can use the band outdoors
within about a hundred miles of the coasts. A ship pulling in to port
might then force frequency changes. So the actual use of this shared
spectrum is going to be a complex multivariate problem.

Thanks for posting this Gino,
I read the article and thought it was interesting. My only concern
is there will be that many more bidders in the PAL license area.
I think that this alliance has the capability to be a very good
thing for wisps. But it will make us have to spend the money to
actually purchase our spectrum. This is a new thought for many of
us.
These 3 main players are already in the LTE market with Intel,
Qualcomm, and Nokia already having silicon that can do the CRBS
band. A stable uniform platform may arise from this that may
interoperate between carriers and may give WISPs the first time
chance to partner with celcos with interconnect agreements. Our
networks will have to be able to handle it but I think there is
more revenue possible, at least for Rural WISPs. Companies in very
metro areas are probably out of luck.
The thought of having a large amount of equipment that all uses
the same spec, the same timing mechanisms with GPS sync, allows us
to buy into the technology and share the spectrum. Maybe we can
make this band work the way that we wished all the bands worked
and interoperate with everyone who follows the spec and not be
fighting the big boys all the time….
