ZigBee is the name of a specification for a suite of high level communication protocols.

Supports for critical latency devices, such as joysticks.

The technology is intended to be simpler and cheaper than other WPANs, such as Bluetooth.

It requires only about 10% of the software of a typical Bluetooth or Wireless Internet node.

It consumes very low power and is used in many wireless applications.
