ZigBee is a wireless networking standard focused on low-cost, low-power consumption devices for monitoring and control applications. It uses the IEEE 802.15.4 standard for the physical and MAC layers and provides data rates from 20-250kbps depending on frequency band. ZigBee networks can support hundreds of devices with flexible star, peer-to-peer, or cluster tree topologies and address devices using short or IEEE addresses. The technology is well-suited for wireless control in industrial, commercial, and home automation applications where low data rates and power usage are priorities.

1. Wireless control that simply works

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
