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 rates touch 250Kbps for 2.45Ghz ,40
Kbps 915Mhz and 20Kbps for 868Mhz
band.

4. No wireless network standard that meets the
unique needs of sensors and control devices.
wireless systems don’t require high data rates
but do require low cost and very low current
drain.
proprietary systems are creating significant
interoperability problems with each other and
with newer technologies.
5. Low power consumption
High density of nodes per network
Simple protocol, global implementation
Network Flexibility
Small size-less than 9 mm*9 mm
Hundreds of devices per Network
6. Data rates of 20 kbps and up to 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 devices 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 from a single computer
