Zigbee technology is an industry standard and Xbee is the name of the module. Wireless communication technology is widely used by Zigbee applications such as wireless sensor networks, Zigbee home automation systems, industrial automation, remote control systems, healthcare equipment, agriculture automation. In all these communication technologies. Zigbee is an international trendsetter for wireless communication technology.
Zigbee communication is a specification used to create a communication protocol that creates a network built from low power digital radios. Zigbee technology is an IEEE 802.15.4 standard. It can communicate up to 100m when placed to communicate with other Zigbee modules, but can communicate over long distances when connected to mesh technology. Zigbee is used when it requires a low speed data application with long battery life and a secure network. Zigbee technology is low cost, low power, easy to install, low maintenance and comes with multiple topologies. These specifications made the Zigbee protocol available for use in a wide range of applications.
Zigbee is a specification of mesh network with wireless local area networks (WLAN) that covers a large area. It is designed to provide high data input and output in applications that have a duty cycle such as low and low power consumption. Devices using ZigBee are battery powered. Zigbee is often associated with machine-to-machine communication and the Internet of Things. The IEEE 802.15.4 physical radio specification is used in unlicensed radio frequency bands such as 2.4 GHz, 900 MHz and 868 MHz.
Data can be transferred in two modes: Beacon Mode and No Beacon Mode. In beacon mode, data is periodically sent to the network. During the period of time when the devices do not send information, they enter a low power state to increase power consumption. But close synchronization and network synchronization have precise timing needs, since the beacon period is of the order of low time. Therefore, beacon status reduces costs and ultimately, it is a balance between design constraints and costs. With a non-beacon mode, coordinators and active routers in the network have to stay awake most of the time to listen to the incoming data and therefore need a robust power supply. Therefore, the end devices can sleep most of the time and wake up only to send data and receive a trigger; while the central devices are in active mode, the non-beacon mode creates an asymmetric distribution of energy within the network area creating a heterogeneous network.
