Zigbee Wireless Networking

Foreword

Back in 1999, we saw the need for an organization with a mission to define a complete, open, global standard for reliable, cost-effective, low-power, wirelessly networked products addressing monitoring and control. While there were other standards that addressed higher data rates or battery-powered networks for a very small number of devices, none of these truly met the needs of this market. Instead, what we needed was something focused on:

• Large networks (a large number of devices and a large coverage area) that could form autonomously, and operate very reliably and securely for years without operator intervention

• Very long battery life (years of use from a pair of AA cells), very low infrastructure cost (low device and setup costs), ...
