The Tranzeo radios at least are 802.11, which we refuse to use for fixed

I've talked to quite a few people who are looking at Tranzeo
CPE/StarOS APs for 5.3/5.8Ghz multipoint deployments and have had good
luck myself so far. The combination of StarOS AP units and Tranzeo
CPE units seems to work fairly well. Within a 5 mile radius, you will
probably be able to maintain 15-20meg of throughput and 40-50 subs per
sector depending on the size of the pipes that you deliver to the
customers. StarOS can handle batch firmware uploads, routing at the
AP, bandwidth control at the AP, vlan tagging, OSFP/RIP routing, DNS
at the AP, QOS and packet shaping for VOIP and other traffic and it
also has great troubleshooting information along with hooks into
several of the open source monitoring and traffic graphing systems.
Another plus is that it will run on several hardware combinations, so
you can choose the type of radio/sbc platform that best suits your
needs. The Tranzeo CPE units are inexpensive ($225-$300), easy to
install and work great with StarOS.
If you go with an all StarOS system, my understanding is that the new
version (v3) will also have the ability to use 5mhz, 10mhz and 20mhz
channels and will be ready for 5.4Ghz with no need for additional
hardware changes. It also works in the 4.9Ghz public safety
spectrum. We provide the backhaul for several video feeds for the
local law enforcement on 4.9 - works great.
I think that is a combination worth considering.

Matt, How much capacity do you need per 5.8 Ghz sector? Is this a
or residential rollout or both? How many subscribers per sector do
to support? How large do you want to scale this network and is
batch firmware loads for radio updates, vlan tagging, voip support
to you? Brad

Subject: [WISPA] 5.8Ghz Multi-point radios
We are looking to start deploying 5.8Ghz multi-point radios at some
of our sites. I am hoping some folks on this list can share
experiences and ideas on what radios might meet our needs. We have
experimented with Canopy and Trango, but would really like some
better choices. From a specification standpoint, Canopy general meets
our needs, but we don't like being constrained on the antenna. We
would like to use sectors bigger than 60 degrees and we would like to
use horizontal polarization. We don't want to use Trango for no other
reason than they can't work with distributors. We really like the
flexibility on many 802.11a-based radios and certainly the price, but
the contention aspects of the protocol and the perception of Wi-Fi
being a consumer grade technology stop us from going that route.
Any thoughts from the list?
