Anyone had any experience with wireless / cellular serial comm?

 

Reliability? Quality methods / brands vs. ones to stay away from.

 

In this exact situation, I'm looking to have one computer wirelessly able to access and download stored data from a single device as needed via RS-232.

Talk about old school.  Still used for petroleum tank & pipeline sensors.  What exactly are you wanting to do?

Well I've got an ultra sonic flow meter in the sewer at a frog farm. It has data logging software built into it that can be accessed via RS-232. All I'm looking to do is have my customer able to access this information wirelessly from a desktop without having to go hook up with a lap top. Otherwise I could convert to 485 and back to run a hard wire.

The Cellular part is only as stable as the coverage in your area.  As for point to point type dial-up, you can get them through places like cdw.com  and this company carries the modems and other sensors.  http://www.directindustry.com/industrial-manufacturer/modem-64087.html  Raveon also has them http://www.raveon.com/  There is also Load Systems International.  http://www.loadsystems.com/
