Mission Statement
ZigBee Alliance members are defining
global standards for reliable, cost-effective,
low power wireless applications. The ZigBee
Alliance is a rapidly growing, non-profit
industry consortium of leading
semiconductor manufacturers, technology
providers, OEMs and end users worldwide.

Development of the Standard
• IEEE 802.15.4 Working Group
– Defining lower layers of protocol
stack: MAC and PHY
– Available today
• ZigBee Alliance
– 50+ companies: semiconductor
mfrs, IP providers, OEMs, etc.
– Defining upper layers of
protocol stack: from network to
application, including
application profiles
– Initial draft available mid 2003
