Zigbee

Definition

Zigbee is a wireless communication protocol designed for low-power, low-data-rate applications, primarily used in the Internet of Things (IoT). This technology enables devices to communicate over short distances while maintaining a long battery life, making it ideal for smart home devices, industrial automation, and other IoT applications. Zigbee operates in the 2.4 GHz frequency band and uses a mesh networking topology to enhance communication range and reliability.
