ZigBee is a set of standards for low-power, low data-rate networks that operate over small distances. ZigBee networks work even in congested radio environments. Up to 255 devices can be connected in a network, a maximum of 30 m away from each other.
How does ZigBee work?
ZigBee is a wireless network of devices that communicate with each other. Modest amounts of data are shot over small distances. ZigBee devices can be arranged in a Star network, where devices report to a ZigBee Controller; a Mesh network, where all devices are at the same level and ‘cooperate’ with each other; or a Clustered Tree network, which combines the best of both.
Why ZigBee?
ZigBee is targeted towards Wireless Personal Area Networks (WPANs), so a ZigBee network is cheaper and simpler to implement than a Bluetooth or Wi-Fi network. A typical ZigBee node will require two to 10 per cent of the software a Bluetooth node would require. Extending a ZigBee network is easy—you don’t need to re-wire any of the devices to add another ZigBee node.
Where would I see a ZigBee network?
ZigBee can be used in homes and offices to remote control every device possible. In factories, they can be used to automate manufacturing tasks and asset management besides monitoring heat and energy usage to optimise energy consumption.
Who thought it up?
The ZigBee Alliance, a consortium of companies, published the ZigBee standard. They monitor and control products that seek to employ the standard.
When was ZigBee started?
Although in development since 1999,the ZigBee standard was ratified by the ZigBeeAlliance in December 2004. In June 2005, the ZigBee specification was thrown open to the public.
