ZigBee Overview


‘ZigBee’ comes from the honeybees. The
honeybees dance in the Zig
-
Zag pattern,
sharing information such as the location,
distance, and the amount of a discovered
food source to the other fellow members.

ZigBee Overview


ZigBee is a communication technology
for wireless networks looking for
lower cost, reduced protocol
simplification, and higher
communication reliance and quality.


Power are the batteries. The MCU
and the transceiver can go into
hibernate state. Date rate is 250kbps
for 2.4GHz radios.

ZigBee Protocol


ZigBee Alliance organized by Ember,
Emerson, Freescale, Philips, Texas Instruments
and other world famous companies more than
100 totally.


ZigBee Alliance united the company members
together to enable reliable, cost
-
effective, low
-
power, monitoring and control products for the
world.


The ZigBee Specification is set up by the
ZigBee Alliance.


ZigBee Protocol


ZigBee Protocol is divided into
physical layer, media access control
layer, network layer, and application
layer. Physical layer and media access
control layer protocol is set up by IEEE
802.15.4 group formerly
.
