Does anyone know how well this is penetrating areas with lots of trees?
I would guess a few trees would knock this out just as easily as it does
2.4 GHz Wifi? Thoughts?

I'm not going to get into an enormous amount of detail, but I know a
well-known licensed 2.5ghz NLOS provider, has a maximum NLOS range around
their towers of about 3-4 miles (with indoor units). That said, the
Sprint-Nextel spectrum is very unlikely to be available on independent
lease, and you would be better off contacting whoever is a non-profit or
educational licensee in your coverage area for spectrum access.
Also, don't discount 2.3ghz, you may be in a coverage area where WCS is
available. 4.9ghz is okay but I haven't seen a lot of case studies showing
where it penetrates trees compared to 2.5/2.3ghz licensed.

Blair/Chris: I worked with my local WISP whose been in
the business a long time and loved helping them to
build their business. We installed a combination
mobile mesh/fixed wireless system using equipment from
a major manufacturer and provided the following:
Wireless Mobile mesh network with the 4.9 GHz license
Electric utility metering using the 2.4 GHz (WiFi)
in a Point to Point and Point to MultiPoint. The fleet
manager will eventually have the modem and mobile
server installed in each truck. The utilility meters
used a 2.4 Ghz chipset but we had to select the best
channel out of 1-13 channels and locked in SSID at
Channel 5 after RF spectum analysis (which really
means we walked around with a sniffer).
There are other "mobile modems" that you can utilize.
I can hardly wait for the new WiMax 802.16(e)/WiFi
802.11(n) Intel Montevina (Centrino) platform to
arrive. But of course that means you need a 2.5 GHz
license. But as one reader posted I think Sprint may
be eager to work with someone on a lease basis to
build the business case.
I hesitate to mention any manufacturers for fairness.
With that being said IMHO it can be designed,
commissioned and installed with good RF Planning.
I prefer and my field advice is to identify and work
through a VAR, channel partner or disributor type VAR
who can give you personalized service. Some WISP may
have that capability. I built my local WISP into a
solutions provider and certified on Mesh.

This is an invitation to Vendors to contact me if
they have equipment
that could meet my needs...
I have been contacted by government unit that wishes
to deploy a mobile,
high speed data network in their vehicles.
The area of operation is tree infested. The mobile
units will never be
more than 7 miles from a tower with a base station.
LoS is NOT assured
from the mobile unit to the base. The mobile units
must switch base
stations as needed with no user intervention.
Use of 2.4GHz band is not acceptable.
Min data rates are 256Kbit up by 1Mbit down.
I'm open to any technology that will work and to any
vendor. Licensed
or unlicensed gear would be acceptable.
Contact me by e-mail or my cell below. Calling late
is fine. I'm up
late anyway!
