Matt,
The primary advise I'd add is, Test the various encryption compatibility
betwee nTranzeo and StarOs, before getting to many clients on-net.
We found some compatibilities some CPEs and Star OS at a couple of our jobs.
It was a pain to experiement n a live network when we risked locking us out
of the subscriber's CPE. I really like the StarOS Menu Interface, because
it is so easy and clear. However one of the big reasons we chose Mikrotik
for our standard for Wifi APs now is that the Mikrotik supported virtual
APs, allowing us to setup multiple encryptions configurations at the same
time, so it was easy to setup a test configuration and slowly move customers
over without risking downtime for the subscribers.
Also, to get top modulation, don't hesitate to add plenty of margin on the
CPE antenna gain, good SNR is key to getting the high speeds of the higher
modulations.
The conversion should be a peice of cake for you because you are going from
2.4G wifi to 5.8G wifi, and already aware of the Wifi limitation that are
shared between the two similar technologies.
Others have pointed out to me that disabling connection tracking on the AP,
greatly increases throughput of the AP. We also found the WRAP board to be a
hardware limitation to increasing cellsite speeds.
5.8G isn't going to survice nearly as well as 2.4G will on links that you
were pushing LOS and trying to power way through trees and foliage.
However, 5.8G has half the freznel zone height, so you don't have to be
quite as high above the tree line as 2.4G to squeze in a link.

Subject: [WISPA] Experience with 802.11a 5Ghz PtMP deployments
Hello all,
I am getting ready to start migrating my higher end customers from 2.4Ghz
to 5.8Ghz radios. I will be using Tranzeo CPEs and StarOS APs for this.
My question: Is there anyone out there who has done this and has quite a
few people on 5ghz (802.11a based)? I'm not talking about Canopy or
Trango, just 802.11a.
I'd like to know what kind of speeds are deliverable, number of clients
per access point, preferred pricing plans for bandwidth and any snafus
that have come up. I'm hoping to avoid snafus if possible by knowing as
much as I can before deploying.
Right now we have about ten people on our system between three access
points and plan on migrating another 50 over. The furthest person at 7
miles (using a 26db grid antenna), and I would like to cover a range of 4
to 8 miles per 5Ghz cell.
Any input is appreciated. I will make sure and submit the results of my
implementation project in another month or so.
