It’s really sub 1GHz frequency

Everyone I talk to says the NLOS of Tarana is bonkers amazing.
I've always felt there has to be some technology besides simply wavelength and power to get through buildings based on how well cell phones work in buildings. The uplink from the phone to the tower can't be that much and it can't simply be the 6 foot sectors.
I remember another promise of Wimax. NLOS
Patrick was always announcing super NLOS performance on one product or
another.
NLOS with trees, yes. Blocked by a hill.... color me skeptical.

Tarana definitely does NLOS a lot better than any of its
predecessors, but as far as "making every install work" goes, I'm still more
than a little skeptical... perhaps that will change after I've had more
experience with it, but I have my doubts. There are way too many variables in
different NLOS situations for me to just go by what other people say. We've all
heard those stories way too many times over the years.
Jeff,
I know someone who tested
Tarana and he seems convinced that it’s the NLOS holy grail that we always
wanted. Like what every Wimax and LTE vendor promised us and couldn’t
deliver. We have a long history in the industry which should make us all
skeptical of NLOS claims so I’m curious if it’s really as great as all that.
Any comment, Jeff?
When we were doing 5ghz
canopy, we bracketed our city with a dozen towers to give ourselves lots of
options and we still had to end up saying “no” to half our installs.
This is urban/suburban so we’re usually talking about one rooftop or one row
of trees in the way. At most 100ft of foliage to penetrate before you’re
in clear skies. 5ghz Canopy would work, but it tended to be unreliable
in those conditions and we just found it wasn’t worth the trouble and the
damage to our credibility if we installed it. Our Alvarion VL using
neighbors always talked up how well their thing worked NLOS, but their actual
outcomes and my own testing of the product told me that it only “works” NLOS
within certain definitions of “works”, i.e.: you’d have to willing to accept
high error rates and low MCS as “working”. Anything else built around a
WiFi chipset I’d lump in with Alvarion.
900mhz of course worked
within the limits of its bandwidth and high interference, and I’d say more or
less the same about 2.4ghz.
Wimax was an incremental
improvement because you could get some predictable and reliable outcomes NLOS,
but your NLOS customers are still lowering efficiency of the system due to
retransmits and lower MCS, and I never saw a Wimax product that wasn’t a total
PITA on the management side. I bitched endlessly about the Motorola
CAP320, but after seeing what some other vendors had I think CAP320 might have
been the cream of the crop as far as operability. LTE was another
incremental step up, but at best maybe half as good as it was hyped up to
be.
If Tarana makes every install
a success then we should give them all of our money and be happy to do it, but
it absolutely better work.

G2
I can get you any pricing you need.
My understanding is that the G2 will be dual band, 3 and
6GHz. It will be able to use 4x 40MHz channels and still provide all the
interference mitigation of the G1 with 2x 40MHz
channels.
I’m sure there is more, but that is what I know
now.
