  4. 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. Ed Callaway, Motorola

  5. 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 APPLICATION Customer ZIGBEE STACK ZigBee Alliance SILICON IEEE Development of the Standard Ed Callaway, Motorola

  6. The ZigBee Alliance Solution • Targeted at home and building automation and controls, consumer electronics, PC peripherals, medical monitoring, and toys • Industry standard through application profiles • Primary drivers are simplicity, long battery life, networking capabilities, reliability, and cost • Alliance provides interoperability and certification testing Ed Callaway, Motorola
