ZIGBEE TECHNOLOGY

Wireless control that simply works

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.

What is ZigBee ?

Worlds Most Common Frequency Bands

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.

Why ZigBee is needed?

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

Features of ZigBee

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%)

ZigBee General Characteristics

Network Architecture

ZigBee Layers

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)

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
