Zigbee in a nutshell
Zigbee is an open global standard for low-power, low-cost, low-data-rate, wireless mesh networking based on the IEEE 802.15.4 standard. It represents a network layer above the 802.15.4 layers to support advanced mesh routing capabilities. The Zigbee specification is developed by a growing consortium of companies that make up the Zigbee Alliance. The Alliance is made up of over 300 members, including semiconductor, module, stack, and software developers.
Through its mesh and routing capabilities, Zigbee allows the transmission of data over long distances by passing the data through a mesh network of intermediate nodes to reach more distant nodes. Transmission distance ranges from 1200 to 3200 line-of-sight meters (5280 to 10560 feet). Zigbee supports multiple network topologies such as point-to-point, point-to-multipoint, and mesh networks and allows up to 65,000 nodes per network.
Zigbee is designed to provide the following features:
- High reliability
- Low power consumption
- Low cost
- High security
- Simple protocol, global implementation
