IEEE Std 802.15.4

IEEE Std 802.15.4 is a technical standard that defines the protocols for low-power, wireless personal area networks (WPANs). It enables small devices, like sensors and smart home gadgets, to communicate efficiently and reliably over short distances with minimal energy consumption. The standard specifies how devices access the wireless medium, organize data, and coordinate communication to reduce interference and conserve battery life. Often used in Internet of Things (IoT) applications, IEEE 802.15.4 provides the foundation for technologies like Zigbee and Thread, supporting secure and scalable wireless connectivity in everyday environments.
