We produced an open source design for a low cost Software Defined Radio (SDR) transceiver platform. SDR allows a single piece of equipment to implement virtually any wireless technology (Wi-Fi, Bluetooth, GSM, ZigBee, etc.), and we hope the availability of a low cost SDR platform will revolutionize wireless communication security research and development throughout the information security community.
