Design and development of FSK based wireless communication system for remote switching

Abstract

A simple and low cost wireless transmission system has been designed and developed. Digital signals in the form of binary digits (bits) are chosen for wireless transmission using FSK technique. Signals are software generated and passed through the parallel port of a computer. A sophisticated FM transmitter is also designed and implemented for faithful transmission. A simulation of the hardware design is done to know the transmitting frequency and a standard commercial receiver has been tuned to detect the signal. The receiver tuned frequency matches with the simulated frequency signifying that the implemented system is efficient for wireless communication.
