Zigbee

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. !! More Information There might be more information for this subject on one of the following:
