Just sensors? no actuators? Tx only from remote devices?

Asking for diagrams sounds a bit lazy... get your thinking going!!!

Check this issue of CONTROL mag, you should find many things you need to know about commercial wireless industrial stuff:

Are you sure that your signal is wireless?

You can look up for the RS422 signal. It use the 4-20mA current loop.

Here is a link for a wireless 4-20mA Gateway and Node. Range is up to 2 miles if you use the 2.4Ghz model.

Phoenix Contact has some great products for 4-20mA and you can create a configuration online. It's good stuff. http://www.phoenixcontact.com/signal-level-matching/31240_15482.htm
