Overview#
Zigbee is an IEEE 802.15.4-based specification for a suite of high-level communication protocols used to create Personal Area Networks with small, low data rate, low-power Wireless, such as for Home Automation, medical device data collection, Internet of Things (IoT) and other designed for small scale projects which need wireless connection. Zigbee is a Low-Power and Lossy Network, with low data rate, and Wireless Network for Personal Area NetworksZigbee networks are Personal Area Networks (or PANs). Each Zigbee network is defined with a unique PAN identifier (Zigbee PAN ID), which is common among all devices of the same network. Zigbee devices are either preconfigured with a PAN ID to join, or they can discover nearby networks and select a PAN ID to join.Zigbee supports both a 64-bit and a 16-bit PAN ID. Both PAN IDs are used to uniquely identify a network. Devices on the same Zigbee network must share the same 64-bit and 16-bit PAN IDs. If multiple Zigbee Networks are operating within range of each other, each MUST have unique PAN IDs.!! Zigbee Network Device types
Zigbee defines three different device types:
Zigbee networks may have any number of end devices. In fact, a network can be composed of one Zigbee Coordinator, multiple end devices, and zero Zigbee Routers.
Operating channels#
Zigbee uses direct-sequence spread spectrum modulation and operates on a fixed channel. The IEEE 802.15.4 Physical Layer defines 16 operating channels (channels 11 to 26) in the 2.4 GHz frequency band. !!
