Wireless Data Communication Between Two Computers

Abstract

In this project the main task is to establish a connection between two computer using RS 232 protocol and the connection should be wireless. Purpose of doing this project is in a rural area where there is absence of any kind of network or there is natural calamity where there is no network present and people still want to communicate within a particular area so they can use it. So we have used our best knowledge and experience to design this project. In this project we mainly used discrete electronics components and because this is wireless so there should be an antenna so we designed helical antenna which is best for this project and we want to make it simple and cost effective so we hardly used any kind of chip. The project has implemented step by step in several modules and stages. In first stage we designed wired data communication system using RS 232 and Matlab after that we designed modulator and demodulator and this worked. Since connection should be wireless so we designed antenna which is helical in nature and its radiation pattern has been plotted and observed after that we added these antennas at the transmitter and receiver
