ANDROID BASED ANTENNA POSITIONING SYSTEM

To receipt the strongest possible signal, the antenna must be pointed at a precise angle in the direction of transmitter for effective wireless communication. If the movement of the antenna is controlled manually, there is a problem of aligning it at the optimum position to receive the strongest...
