I'll chime in with a few comments:
I admit to having been frustrated by the requirements in the 3.65 GHz
ruling by the ambiguity of the cooperation requirements and for sure
there are no first in rights. However, what I am seeing thus far in
practice is that first movers do enjoy a meaningful advantage in their
markets. Since WiMAX does represent a more significant CAPEX investment
on infrastructure, operators are reluctant to deploy aggressively in a
market where several operators are already live. Second, since the rule
does not define neither the nature nor extent of the cooperation, the
first in operators seem to have a leg up with the next in folks needing
to work around them to some extent. At a minimum, cooperation as it
relates to 3.65 GHz is a boon for the lawyer class and since most WISPs
are loathe to deploy an attorney to battle the first in's attorney, many
opt to find greener pastures. Also, according to me Redline friends, we
are learning that the FCC has rejected some registrations of multiple
operators on the same tower site. So on balance, the interference risks
in 3.65 GHz are minimal as compared to 5.x GHz and certainly the other
ISM bands.
I do wish that the FCC would use some of the 3.65 HGz license fees to
create an enforcement pool, as well as defining a more specific set of
rules and procedures for the human side of 3.65 GHz cooperation.

John,
What are your thoughts about using the 3.65ghz band that has no
capabilities to handle any type of noise rejection? One of my big
concerns with 3.65ghz is spending a lot of money on base stations,
NMS, etc. and then having someone purchase a $3,000 LigoWave 3.65
point to point link and shut my system down completely. I believe this
to be a _very_ real concern in this space.
I know the Vecima equipment is just a frequency change from their
3.5ghz equipment. I know equipment in that band has nothing to deal
with noise, because they are licensed frequencies and therefore don't
need to worry about interference. Do you have concerns about this? The
FCC has already said that problems will need to be "worked out", and
that they are not going to step in and do anything. It will NOT be a
first come first serve basis as many believe.
Thoughts? Comments?

Ummmm.... pricing is WAY, WAY different.
Redline AP's are around $10k
Vecima AP's are around $4k
Redline has an FCC approved system with 3 - 120 degree sectors with a
3-way splitter which allows for full 360 degree coverage now with one
sector controller with upgrade path for more sector controllers as
your needs increase over time. Redline supports uplink
sub-channelization which adds about 15 db of increased receive
sensitivity to your CPE to base station link. I find the cost is
justified for the Redline system and I have one online that I am very
happy with. I am moving my leased line connections to WiMax with
better speeds and erquivalent reliability. The ROI for this base
station ist less than 2.5 years now and will improve as I add more
customers. I feel very satisfied with the Redline system and am
confident we will add more Redline bases in the future.
Redline CPE's are $300 each (even in 250 quantity) Vecima CPE's are
less than $249
Redline CPEs are built like a tank. They have the Intel WiMax Ruby
chipset (the best available at any price). Future migration to 802.16e
for this CPE is a firmware flash. It is true that you have to buy 72
radios (not 250) to get the $300 price point. They are well worth the
money. I take a Redline CPE in with me on sales calls. The quality
helps me sell WiMax.. It is that nice of a piece. It is the best
quality CPE device I have used. It is very similar to the quality look
and feel of the Alvarion VL CPE radios.
And, I was told Tranzeo is making Redline's CPE as well? Could you
send a picture of the Redline CPE?
This is not true at all. Tranzeo and Redline CPEs are night and day
different from one another. The quality of the Redline CPE was a big
part of my decision to choose Redline as our WiMax platform. Nothing
touches the Intel Ruby chipset. It is the best going.
