Ok, so just an idea i had, but not at all sure if it will work or even if it can be done.
Imagine having 1 GSM modem based in a building that passes information it receives to a radio module and broadcasts it to any listening devices in that building.
Now im out and about somewhere and i call that modem from a tablet PC.
Is it possible to establish a link whereby i can then send data to that modem and the information sent be broadcast via radio, then the radio will receive a response and send it back via gsm modem to my tablet so i can read it.
Can this be done?
If anyone knows it can what do i look for for information on the subject, iv google various keywords but not getting the correct answers.
