One thing I am wondering about, and it's not an Alvarion specific
question or concern is, isn't it true that when you use a subscriber
unit as your backhaul on a PtMP set up like you are suggesting, that the
through put is halved or somewhat diminished?
Thought this was a long standing rule of thumb.

Patrick,
Thanks for that info - I appreciate it much.
What I am trying to accomplish is (kill a bunch of birds with one stone)
connect these 5 remote locations via wireless to the hospital (AU located
here) and then use the 6th SU on my tower (1 mile LOS) to provide 10mbps of
dedicated bandwidth to the hospital.
Thanks,
Mac Dearman

Mac,
I understand you spoke to Les today. Made me smile for sure. Thanks also
for sharing the story about Michael Eck helping during Karina. He is a
humble guy and I've never heard him mention it.
The BreezeACCESS VL can certainly do what you want there. An AU,
especially at those ranges should be able to provide the full capacity
of just over 30mbps (net ftp). So you could provide 6 connections close
range of 10mbps a piece with an oversubscription ratio of only about
2:1. Assume that a typical over subscription for high end commercial
customers is about 4 or 5 to 1, you should be sitting pretty.
I am not clear about your tower need. Are you asking if you can
dedidcate 10mbps to a tower, which then would have that capacity used to
feed in to 802.11 APs that feed other clients?
1. How far is that tower?
2. You should be able to dedicate 10mbps to the tower, leaving 20mbps to
serve the 6 hospital customers with an oversubscription ratio that would
still be nice and low.
Do have Mike Cowan confirm, as John advises.

Subject: RE: [WISPA] ALVARION VL 4.0 AP
Someone give me a hand here please.
I have a contract to deliver 10Mbps dedicated bandwidth to a hospital as
well as building them a leased wireless network for the hospital to 6
off
site buildings. All of these buildings (but 1) are with in "rock
throwing"
distance of the Hospital. I am looking at the Alvarion VL 4.0 AP to do
the
wireless connections.
Here is my dilemma since I am very limited in VL knowledge:
1. Will I be able to not only connect these 6 out lying buildings, but
also
place one of the SU's on my tower to provide them with the 10Mbps
dedicated
BW?
Or will I need to do a PTP?
2. I believe the AP is only possible of 10Mbps total???
Thanks,
Mac Dearman
