ZigBee is a low-power, wireless communication protocol designed for IoT devices. It is commonly used in smart home applications, including lighting, security systems, and sensors. ZigBee operates on a mesh network, allowing devices to relay data to one another, which enhances coverage and reliability. It supports low data transfer rates, making it ideal for devices requiring minimal bandwidth. ZigBee is known for its energy efficiency, enabling longer battery life for connected devices. It uses the globally available 2.4 GHz frequency band and supports secure communication through encryption.
