An Ad Hoc Broadcast Scheme Using the Radio Data System (RDS) in the FM Band

Most contemporary Smartphone contain ICs that integrate multiple radios on a single chip. Common configurations are ICs with 802.11b/g/n Wi-Fi and Bluetooth radios, a GPS receiver, and a FM transceiver. The Radio Data System (RDS) broadcasts short datagram's in the FM band (87.5 to 108.0 MHz). RDS is primarily used by commercial radio stations to periodically broadcast station identification information or metadata regarding the current content being aired. Part 15 of Title 47 of the code of federal regulations governs the RF emission limits of license-exempt FM modulators that can be used by consumers.
