Social media is an emerging way to connect people and its ubiquitous presence has increased its importance. It connects people in different parts of world, with different backgrounds and similar interests with each other. San Diego State University's research group is developing a device called as the "Smart Badge" with which people with similar business or personal interests can be connected with each other. A FM transceiver is used for the same because it has a low power transmitter and can be used for short range communication in an unlicensed FM band. The intent of the network is to exchange messages through broadcasts to its neighbors within a short range. The FM frequency band is chosen for short range data communication and this frequency band is un-crowded when compared to the more popular ISM band. Hence four broadcast schemes were designed for efficient, short range broadcast based data exchange using the FM frequency band- (1) Transmission Scheme one for Ad-Hoc small scale network with peer-to-peer communication (2) Transmission Scheme two for Ad-Hoc small scale network with peer-to-peer communication (3) Transmission Scheme three for Ad-Hoc small scale network with peer-to-peer communication (4) Transmission Scheme four for Ad-Hoc small scale network with peer-to-peer communication. The first scheme involves broadcasting the packets at regular intervals. The second scheme is to understand how a system behaves when large dynamic packets are used. The last two schemes involve a "Carrier Sensing Scheme" for Ad hoc FM transceivers. These schemes will ensure that FM transceivers can be effectively used.
