Introduction to ZigBee
Technology
The ZigBee Alliance defines low-power
wireless communication protocol stacks and
profiles designed for monitoring and control of
devices in a variety of markets and applications.
These include consumer, smart energy, control
and automation and medical markets. There are
two different specifications (ZigBee and ZigBee
Consumer) as well as multiple profiles that focus
on specific markets. Freescale provides the
necessary building blocks used for both ZigBee
and ZigBee Consumer solutions, including
hardware, software, tools and reference designs.

Freescale Solutions with
ZigBee Technology
The ZigBee protocol stack is designed for
monitoring and control applications such
as building automation and smart energy. It
features self-forming and self-healing mesh
networks that help differentiate it from
other technologies.

ZigBee Health Care
Profile and IEEE 802.15.4
For medical care providers, access to timely
and accurate information improves the ability
to provide the highest quality of patient care.
Decision support is not limited to just the
bedside. The quality of care often depends
on the ability to share vital patient data with
clinicians in real time outside the care facility.
This means clinicians can provide immediate
feedback to attending physicians based on
real-life clinical research as well as track
treatment paths, and give results beyond the

walls of the hospital over the patient’s lifetime
to improve future treatment methodologies.
ZigBee technology is rapidly proving to
be useful in these applications. It can help
provide greater freedom of movement for
the patient without compromising automated
monitoring functions. ZigBee technology
can be deployed in a number of products
that can help ensure better patient care and
more effective care tracking by providing
cost-effective, low-power wireless technology
that can cover large buildings and institutions
with mesh networking.
Freescale has received ZigBee Certified
product status for its ZigBee Health Care
wireless health and wellness processing
platforms. The ZigBee Certified products
status is awarded to products that have been
tested and met criteria for interoperability
that enable wireless devices to securely and
