RE: [WISPA] Atheros speed WRAP vs RB532

2005-11-13 Thread Paul Hendry
Hey Gino,

Are you using the Spectra's in a NLOS environment? If so, what sort
of obstructions are there and what kind of throughput can you get? Looking
to get a pair for a link but a bit expensive if they can't deliver.

Cheers,

P.

Ahhh you've never cracked one open to see what's inside?

Ask Gino, you have to take everything apart and see what makes it tick.

Paul,

I haven't tried the Spectra yet but am planning some links with the
Link Estimator. Are you familiar with this tool? You may have to attend
a training session to get access to the partner site and profile
generator. However I'd be happy to generate a path report for you ..
the tool is quite good, and at least the sales people will tell you
it's very accurate - if it says 99.999% reliability, that's what you'll
get. Trees and other obstructions can be added to the profile manually.
The single biggest factor is antenna gain .. you just won't get 200
Mbps over 40 km without 4' dishes on both sides.

What about NLOS (trees and buildings) @ 3km
with a max EIRP of 33db (as thats what we are stuck with in the UK L) or 28km with good
LOS/Fresnel clearance with max EIRP of 33db?

RE: [WISPA] Atheros speed WRAP vs RB532

2005-11-13 Thread Rick Harnish








I have installed 3 Spectra Links so
far. NLOS performance will be best
in municipal environments with plenty of buildings to bounce off of. I did try to make a 6 mile NLOS link
with trees in the path before I recommended the construction of a tower. I wanted to see the potential. If the path obstructions are in the
middle of the path there is a much higher probability of success, however, if
the obstructions are near the ends of the link the chances of success are much
less. This particular path is in a
rural area without reflective surfaces.
NLOS links will drop bandwidth potential rapidly. All calculations I have done so far point
to a 20 mile limit for 200+ Mbps throughput. The newest firmware released a few weeks
ago improved bandwidth on one of these links 50 Mbps. I was very impressed with that, good job
Orthogon. That link is running 6
miles with LOS and 2 Dual Pol dishes. It is running about 175 Mbps
currently. We will be switching to
3 dishes in a few weeks to peak out the performance capabilities of the
link.
