Abstract
The world is being digitalized so is the advancement in field of communication. Wireless communication plays a vital role in this digital world. Point to point communication (single transmitter single receiver) has led to Multi-point communication (single transmitter multiple receiver) which is the need of this modern world. This paper discuss details related to transmission of audio signals through wireless medium using Radio Frequency. The paper is aimed at developing “Wireless Audio Transmission and Switching System for Public Address”.Most of the devices available now which are present in wireless system works on Bluetooth and Wi-Fi. This restricts their range and create issues regarding bandwidth. The device discussed here will be able to send the data over a range of 60-100 meters (LOS).The microcontroller is used for signal processing, configuration and switching of receiver.This product is cost effective and the price can be reduced to a more extent in case of mass production.
