What are your data requirements? Do you need a constant connection to the system, or do you just need periodic reports of values (once per hour, daily summary, other?)
Do you have cellular coverage and access to power in the area?

Thanks for the reply. I'm building a box that'll allow the user to
remotely control a water quality analyser, through a web interface. Most
of our application would have wired LAN access but there are cases where
the machine is in a remote area. So basically the device will have to
have TCP/IP wirelessly ( or I'm on a completely wrong direction ). Again
I'm not used to industrial standard, etc. So if there is a remote
wireless TCP/IP solution, I'm all ears.
