Foreword
Back in 1999, we saw the need for anization with a mission to define plete,
open, global standard for reliable, cost-effective, low-power, worked
products addressing monitoring and control. While there were other standards that
addressed higher data rates or battery-works 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:
● works (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), very plexity, and
small size
● A relatively low data rate
● A standardized protocol, allowing multiple-vendor, interoperable products for the
global market
Thus, in 2002, the ZigBee Alliance was born.
Now, with over 225 panies, we are able to draw on a wealth of experience in
every aspect of the business. Allowing so panies the opportunity to have input
is not as fast-paced as adopting a single proprietary system and declaring it a standard.
Even so, bined wisdom and the vetting process enable a much better solution to
be built, one which meets all of the needs mentioned above. Getting it right is extremely
important if a standard is to have a long track record of ess.

x Foreword
The ZigBee Alliance slogan, “ Wireless Control That Simply Works, ” is clearly what is
needed for end users and implementers, but achieving that result places a heavy burden
on the developers and OEMs. Drew Gislason has the ability to plex topics and
present them in a manner that is cogent and easily digestible to OEMs and developers.
This book goes a long way in helping to explain ZigBee concepts, and in explaining how
to implement
