Dear Frineds,
I have to create a RF communication between two distant 51 microcontrollers, i.e upto 700 meters. I am aware of the microcontrollers but i want to know some details about the RF communications IC's that can be used to achieve the range mentioned above. At the same time i would like have some useful material about RF communication for long distances.
Please suggest the details required,
regards, chandu
If you use GSM, you don't have to worry about any RF details at all, and the range is effectively unlimited - just so long as there is GSM coverage in the area(s) concerned...
but there are usage charges...
