Zigbee is a low-power wireless communication technology designed for small to medium-sized networks. It has been designed to provide reliable data transmission over short distances, while keeping power consumption very low. This makes it an ideal choice for home automation systems, smart home systems and smart cities.

Zigbee is based on the IEEE 802.15.4 standard, which defines the physical (PHY) and data link layer (MAC) for wireless communication. It operates on a variety of RF bands, including 2.4 GHz, 915 MHz and 868 MHz. Because of its low power consumption, Zigbee devices can run on batteries for long periods of time, making them ideal for use in various Internet of Things (IoT) devices.

One of the main features of Zigbee is its ability to form networks with routing in the form of mesh networks. This means that devices can communicate with each other by passing data through intermediate nodes. This approach ensures high reliability and resilience of the network, as well as the ability to expand coverage by adding new devices.
