Hi Eric,
?
I would look at some of the newer Ubiquiti and similar WISP
equipment for high-bandwidth backhaul. Although Motorola Canopy equipment is
excellent, you may not be getting your best bang for the
buck.
?
We have used AvaLAN 900 MHz links for up to 23 miles, and I
would have another choice today because of the need to pair the AvaLAN radios
before installation. When mounted on a commercial or government tower, the
largest cost is the tower climb and installation. When something goes wrong with
one AvaLAN radio, it requires two tower climbs to create a new pair and install
them at two sites. Not so with Ubiquiti and other equipment. We have experienced
this at least three times: a lightning strike repair, and two times to re-aim
antennas and insert a new node in a chain of links.
?
Check out the new Ubiquiti Rocket and Bullet radios on 5.8
GHz. They can be configured from the ground and reset in any number of
configurations. A high-quality?antenna+radio can be purchased for less than
$300. $500 for a pair to make a link is extraordinary, and you may find you can
afford some spares or additional links with your budget.

I haven't used the Motrola Canopy equipment, but I've heard good things
about it.
?
There are members on the group who have used unlicensed 900 MHz
/?5.8 GHz IP data linking
solutions from AvaLAN Wireless. I believe their data rates are around 1
Megabit/sec.
You can find more information at:
?
Looking at AvaLAN's?web site it appears you could put up a link with
two 5.8 GHz data radios & antennas for around $2,000.

Backhaul on Motorola Canopy 5.8 GHz
?
I am looking for information from users that my have attempted to utilize
the Motorola Canopy equipment as a back-haul to provide WAN access at a remote
site. We are preparing to install our second D*STAR Cluster including DD on a
2000' tower that is some 30 miles away from our current tower.
Paths
calculate out to be within acceptable range, we are also utilizing the largest
parabolic dishes commercially available for Canopy equipment. Frequencies will
be on the 5.8 GHz since regional partners would not approve our request to
utilize 4.9 GHz licensed service. What I am curious about is if anyone has
attempted to test this type of setup for your location. We are utilizing grant
funds for the purchase of equipment so we have backing from our Emergency
Management Agencies.
The system was designed by several members but,
path information was calculated using Radio Mobile Deluxe and confirmed with
calculations by a retired AT&T Microwave Systems Technician.
Thanks for your assistance.
