Microwave oven is a 2Ghz device. It's made from a radar magnetron
developed for the army/navy/coastguard. The frequency is used because
it bounces off almost everything. The magnetrons used in the slightly
higher powered radars from WW2 operated at 5Ghz and their range was
about 100 miles. The operator could tune it in to see seaguls on a pier
because it could bounce off clouds and peer over the horizon, clouds
move and then the image is gone. These signals are strictly LOS and
worthless around any sort of plant matter especially at the low power
we're limited to. Air search radars use 400-450Mhz, these frequencies
penetrate yet still reflect off of moisture in clouds and hard surfaces
on airplanes and missiles and travel many hundreds of miles, where
reception distance is limited by the rotation speed of the reflector
dish and the sensitivity of the receiver. The lower the frequency, the
better it will penetrate matter. 900Mhz radios is about as low a band
you can go and still get a decent amount of usable data-stream. I would
think that if you could build better discriminators in the circuitry you
could get a hell of a lot more data throughput. But 900Mhz is the only
commercial radio frequency that can penetrate woods and still function
as a data-stream. The real problem is the manufacturers want maximum
profit and no R&D expense and prefer to tell the customers to go pound
sand.

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.

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.

Jeff

I wish Tarana’s price was the actual price, instead of
sometimes a ton, sometimes a half a ton, sometimes don’t know.
That way, I could calculate how many decades it would be until
each customer would be profitable (outside of subsidized builds).

The G1 is expensive enough, are people actually deploying

necessarily a deal-breaker - those subscriber units though...

Has Tarana done this by announcing the G2 while all
they have shipping is the G1?
Or is the G2 so much more expensive that it’s just for
window shopping anyway? I figure if these are being
bought with BEAD money, frugality may be out the window.
