Hi
If you are looking for lat long values to be sent somewhere you will surely require a communicating medium. Now it depends how far that communication needs to be done. If it is to be done within a smaller radius then you can use RF, Bluetooth or something similar but if it needs to be done for a larger distance then you will have to use GSM, WiFi or similar technologies. If you do not want to use internet as a medium of communication then you should look out for using GSM.
