IEEE 802.15.4 is the IEEE standard for the physical (PHY) and medium access control (MAC) sublayers in low-data-rate wireless networks. It describes the radio technology used in smart home applications for battery-driven devices, providing for relative simplicity, very low power consumption and a low rate of data exchange. Multiple physical layers are defined to operate in a variety of geographic regions with a variety of frequency bands.
The first version of the standard came out in 2011, another version in 2015, and the current version in 2020, and there have been four amendments to the standard since 2020.[1]
The IEEE 802.15.4 specification is publicly available from the IEEE.
