That is a very vague question, when you say "remote locations" it could mean almost anything.
First you need to establish whether there is an electrical supply at the location, then decide if the information is to be sent 'live' over a wireless or cable link and if not, how it is going to be stored so it can be retrieved later. How you actually send it is entirely up to you, each method communication has good and bad points but the deciding factor probabaly has to be the distance the data has to travel.
