Did a little arithmetic tonight...

I have a Tranzeo TR5plus access point on my wireless network.  Other 
than being limited by a 10meg ethernet port (it is installed at a noisy 
FM tower location, and the speed must be turned down to 10meg to keep a 
reliable connection) - it is a perfectly standard setup.  It is hooked 
up to a 16db H-pol 90 degree sector, and customer ranges are 1 mile to 
26 miles.   The majority of these customers are on a 1meg plan, with a 
few 2meg and one 8meg in the mix.


This access point has 85 associations on it.  Of those 85, two are 
repeater sites.   One has 35 additional customers on it, and the other 
has 8.  Add them all up, and this one AP is passing traffic for almost 
130 customers.   I see it peak around 6 meg sustained download (4 meg or 
so sustained upload) and if I run a speed test at my house (which is one 
of the customers off this access point) I can pull 8meg back to my NOC.


Anyone who says that 802.11a gear won't scale is full of it.  I'd like 
to see a Canopy based system that would even come close to delivering 
that kind of performance.  I'm planning to deploy 5ghz gear to as many 
of my AP locations as possible this year.   The money spent on that 
access point is probably the best money I've spent on wireless gear 
since I started my current WISP.

The AP is a 5plus, with a 90 degree 16db H-pol sector.

I use the SL5 (16db) up to about 5 miles, 5a20 up to 10 miles, 5a24 8 to 
18 miles and 5plus with 26db grid up to 25 miles.
