Streaming from remote locations - advice needed

[littlefinger]

Does anyone know of any equipment that will help me do the following for this project I'm working on? Basically, the project involves setting up microphones remotely in various locations outdoors for a long period of time (weeks). The microphone is then relayed to a LAN or a radio frequency and streamed to a another remote location where all of the other mics converge (like my studio).

I guess I need some sort of device that will connect the mic wireless to a LAN, data network or some sort of radio frequency. I also need microphones that can handle the great outdoors including rain, snow, wind.

I guess I need some other stuff too, but I'm just trying to get my head around this project for starters.
