internet access for remote areas?

Hi

I am contemplatng taking a job in the mountains near San Ramon in an area that does not have internet cables yet. I am worried about being isolated from friends and family around the world and I also need the internet for research, so I am looking for possible alternatives for getting internet connected. Does anyone know if it is possible to get internet using a dongle (looks like a usb key) in Costa Rica? Or any other suggestions for internet in remote areas?

Many Thanks

Zoe
