IEEE 802.15.4-based specification for personal area mesh networks. "created in 1998, standardized in 2003, ratified in 2004, and revised in 2006." [1] Operates in 2.4 to 2.4835 GHz (worldwide), 902 to 928 MHz (Americas and Australia), and 868 to 868.6 MHz (Europe). Does 10–100m with 250 kbit/sec with focus on low power.
Never heard of this in a quarter century. Not sure if I've ever seen a single reference. Apparently lightbulbs and "person alert" sensors are some of the only real products, and then a lot of hubs.
