We are going to be implementing a 915mHz spread spectrum data collection system (data loggers,) that will have about 6 remote nodes that will have to loop through a repeater node, and about 6 more sites that will report directly to the "main" base unit. The longest hop is about 2600 feet, and has good RF properties. We've already setup a test radio and measured levels at each of the sites in turn to make sure it's going to work, at least as far as the RF hops are concerned.
The units can speak something called PakBus and can store and forward packets between units to make up a small mesh/repeater network. A contractor is putting it all together, including the solar panels and other gear.
Should be kind of fun, actually!
Equipment from Campbell Scientific:
CR206: Datalogger with 915 MHz Spread Spectrum Radio and
RF401: 900 MHz Spread Spectrum Radio
(If anybody is interested..)
Hope it works. At least it won't be blamed on me if it doesn't!
