Abstract: Exchange of information has always been important. Without this it is impossible to express one’s thoughts and ideas. A study in the various modes of communication has bridged this gap enabling an easy and free flow of information among the people. There has always been an effort to develop various ways and methods to make the transfer of information and data, even more efficient. One such study is in the transfer of serial data over a limited distance i.e., within a particular range. To meet the present day technology needs, data transfer at higher speeds is to be achieved which is possible by RF Communication. This project uses an RF Module to transfer serial data in a better way reducing the cost overhead and limiting the drastic effects of noise. In this project we have two sections, one is transmitter section and the other is receiver section. The transmitter section mainly consists of ATMEL8 and an RF Transmitter. The same is also used in the receiver section. It also involves a wireless LCD Display to display the information transferred. Arduino is used as an ISP (In-System-Programmer). This allows us to use the board to burn the boot loader onto an ATMEL. An antenna is also used at both the transmitter and receiver sections. In this method of serial communication, the maximum baud rate is 8000 bits per second. It can be used within a range of 150metre radius (with obstacles). It also has an error checking feature by which the noise is reduced. For the transfer of information within a short range, this method can be employed as it is more efficient when compared to the prevalent methods of data transfer.
