I’m working on a remote controlled weather station project. The distance I need to cover is 200 km.
Currently I’m using 2 mobile phones - one at each side - for communication pusposes (serial comm.), but I would like to use a different protocol than GSM network. Internet is not an option, since it is not present at a remote location.
I’ve been doing a little research and came up with 2 other ways of communication - RF or satellite. Can any of these two be implemented in practice?
Are there any other options for “unlimited” range (or let’s say up to 200 km) communitation? Money is not an issue.
