Low power wireless sensors are limited by current radio technologies to short communication range and low throughput. The authors envision that future radios with advanced software programmable encoding and modulation will bring sensor networks unprecedented flexibility and performance. The authors have taken a step towards realizing this vision by designing a software-based, narrow-band transceiver using the GNU Radio software and the Universal Software Radio Peripheral hardware. They have verified the compatibility of the authors' implementation with existing wireless sensor platforms. They demonstrate the flexibility of their design with sensing applications running on a sensor network communicating over hybrid radios.
