All,

I am looking for information as to (a) approximate costs, (b) equipment sources and (c) opinions from those who have employed any of the following components in remote data collection applications:

(1) Cellular modems

(2) CDPD

(3) GSM

Thank you,

Rick Hudson

 

What sort of range are you looking for? With the devices below, they only work where there is existing cell coverage, there are airtime charges and your data will not be a priority.

We work with spread spectrum radios.
