Whisper

The epoch-making proliferation of Internet of Things (IoT) networks in recent years has brought connectivity to homes, cities, farms, and many other industries. ISM bands are accommodating most of these networks around the world. However, our experience from several global deployments has shown that such networks are bottlenecked by communication range and bandwidth. With these IoT deployment constraints in mind, we propose a new connectivity solution, Whisper [1], where IoT devices can opportunistically transmit data in the TV White Space (TVWS) spectrum, while protecting incumbents from receiving harmful interference.
