FM transmitters

A team at Disney Research is looking at harnessing a technique called ultra-wideband (UWB) ambient backscatter, which would allow IoT devices to save power and ditch their radio transmitters by piggybacking their communications on the multitude of FM and cellular signals already in the air.

Researchers at the University of Washington (UW) have pioneered a technique where everyday objects, such as advertising posters or articles of clothing, can be embedded with transmitters that piggyback ambient FM signals to send data to nearby smartphones and radios using almost no power.

Using locally-transmitted FM broadcasts, researchers at Northwestern University have created a way to improve the speed and reliability of Wi-Fi networks.

A team of engineers from Columbia University has created a nano-mechanical system with the ability to create FM radio signals. In other words, they've built what is effectively the world’s smallest FM radio transmitter.
