[olug] Question about Motorola Canopy wireless equipment

[neal rauhauser]

    After those Ewoks are done saving Zion you'll need their help 
cleaning up your microwave installation if you're operating in metro 
Omaha (see .sig to understand this :-)

  Canopy and Trango are both inexpensive 5.8 GHz radios with 
multimegabit throughput. They *must* have line of site, they can be 
fussy about aiming, etc, etc, and Trango kept their cost down by making 
radios WITHOUT retransmit scheme - whole load falls on OSI transport 
layer, whoa unto you if there are other things operating in your 
frequency. Can't speak to Canopy's methods, but I've got one site 
running Canopy and its better than most wireless I've worked on, but I'd 
doubt the survivability of it in a mobile, industrial type environment 
like a combine.

   If you're looking for an inexpensive way to get telemetry from ag 
gear  I have some questions for you:

1. does it need to be real time, or can it be dropped off by the machine 
once it gets close enough to a radio facility?

2. if it is real time data how fast are you going? If you don't need 
more than a 64k channel there are much better solutions, in terms of 
central site cost & maintenance trouble than using Canopy.

3. how many systems are you talking about tracking? Are you close enough 
to Sprint/Verizon towers to use their internet via cell? Yes, it costs 
monthly, but its predictable and wireless troubleshooting gets *very* 
expensive.
