The IEEE 802.15 TG4 was chartered to investigate a low data rate solution with multi-month to multi-year battery life and very low complexity. It is operating in an unlicensed, international frequency band.  Potential applications are sensors, interactive toys, smart badges, remote controls, and home automation.
