  • Disney Research has determined that one solution may be to get rid of the radios all together and communicate via the ambient radio waves from TV, radio and cell phones.
  • The Disney Researchers devised an ultra-low-power system of sensors that transmit data to a central receiver by reflecting the ambient radio waves from commercial broadcasting systems that already bathe most office environments.
  • This approach radically reduces the power requirements of the sensor nodes because it is the generation of radio waves that consumes most of their battery power.
  • These systems have limited range, which makes them impractical for IoT systems

    Other researchers have shown systems that require even less power by using ambient radio waves from a single source, such as a TV station.
