Introduction
m u
r o
ZigBee is the name of a specification for a suite of high level communication protocols.
f r
e v
Supports for critical latency devices, such as
joysticks.
l The technology is intended to be simpler and i cheaper than other WPANs, such as Bluetooth. s . e It requires only about 10% of the software of a r typical Bluetooth or Wireless Internet node. a h s It consumes very low power and is used in o many wireless applications. f n
