Zigbee is an ad-hoc networking technology based on the IEEE 802.15.4 standard, designed for low-rate wireless personal area networks (LR-WPAN), emphasizing low cost, complexity, and power consumption. It offers data rates up to 250 kbps and supports various network topologies and a high density of nodes, making it suitable for monitoring and control applications, particularly in scenarios requiring low power and cost efficiency. Zigbee is poised to enhance consumer flexibility and control over devices, promoting widespread adoption of mesh networking solutions.

2.  Zigbee is a Ad-hoc networking technology for
LR-WPAN.
 Based on IEEE 802.15.4 standard that defines the PHY and
MAC layers for ZigBee.
 Low in cost, complexity & power consumption
as compared to competing technologies.
 Data rate touch 250 kbps for 2.45 Ghz, 40 kbps for 915
Mhz and 20 kbps for 868 Mhz band.

4.  No wireless network standard that meets the
unique needs of sensors and control devices.
 Wireless system don’t require high data rates
but require low cost and very low current
drain.
 Proprietary system are creating significant
interoperability problems with each other and
with newer technologies.

5.  Low power consumption.
 High density nodes per network.
 Simple protocol, global implementation.
 Network flexibility.
 Small size-less than 9mm*.
 Hundreds of device per network.

6.  Data rates of 20 kbps and upto 250 kbps.
 Star or peer-to-peer network topologies.
 Support for Low Latency Devices.
 Handshaking.
 Low power usage consumption.
 3 frequencies bands with 27 channels.
 Extremely low duty-cycle (<0.1%).

9.  All device have IEEE addresses.
 Short addresses can be allocated.
 Addressing modes:
 Network + Device identifier (star)
 Source/destination identifier (peer-peer)
 Source/ destination cluster tree + device
identifier (cluster tree)

12.  ZigBee will play a vital role in the mass
adoption of cost effective, low power, mesh
networking technology for monitoring and
control applications, based on an open global
standard.
 Near future more flexibility and cost savings
for consumers and greater control over
household appliances.
 Used for campus-wide electrical and security
systems for a single computer.
