Hello Cameron,
As good as Alvarion gear is or may be, it is still best effort gear and
not
committed rate. Many factors will play into what an end user will
actually
be able to produce across Alvarion gear.
If you are looking for a committed rate backhaul you need to look at the
Trango GigaLINK gear again. Completely different class of hardware than
the
VL backhaul products. Yes, it will cost more, but the saying holds
true;
you get what you pay for. Your 3mile link is a cake walk for 18GHz and
if
you have the tower space for 6' antennas the 6GHz GigaLINK is perfect
for
your 20 mile link.
BTW Ralph, our tests on the bench with VL between two MikroTik 3GHz
routers
was decent in HDX. Problem we saw was went you started pushing data
heavily
in both directions the link all but fell apart. Not what you need to
have
happen on a critical backhaul. <grin>
Best,
Brad

Funny you should ask. I tested a B-100 going 500 feet with Qcheck a
couple
of days ago and got only 38 Mb.
I'm not sure if Qcheck reads out correctly or if I have to double it- I
was
in a hurry.

Hello all,
I am in the need of upgrading some backhauls. We are currently using
Alvarion AUVL units with a SU-54-BD. According to Alvarion, this link is
only capable of 16mbit each way (Alvarion, please call it a 32mbit
radio.)
We have looked into results on users who use Alvarion B100, Trango Link
45, etc..
We are open to all options...As long is it works very well. The link is
about 3 miles, but we have another link that is causing the need for the
upgrade that is about 20 miles.
Trango has licensed gear in the 6ghz and 18ghz line that is very
impressive, but just too expensive for us right now.
I would like to know if people are using B100 what is the up/down max
throughput that you have seen? 50/50? etc.. Are you running VoIP over
this? Alvarion claims 1000 concurrent calls over this link, i'm sure
many
of you have not even dented this number.
I am growing to be a big fan of Trango, but have been well, but their
packet per seconds is a lot less than Alvarion B gear at almost 40,000
compared to trango at around 10,000.
Thanks,
I man in dire need of a lot of bandwidth, distance and no spectrum to
put
it....
