Technology to Rule After BLUETOOTH BY MANAS ARORA 0812231057 EC-62 ZIGBEE

HISTORY OF ZIGBEE:

HISTORY OF ZIGBEE In 2003, the standard was completed October 2002 ZigBee Alliance is formed December 2004 ZigBee 1.0 is released Current releases 802.15.4 is 2006 ZigBee specification passed in 2007 2

WHAT IS ZIGBEE? AN INTRO!!:

WHAT IS ZIGBEE? AN INTRO!! ZigBee is the name of a specification for a suite of high level communication protocols. ZigBee Smart Energy is first open standard for Smart Metering across Europe Supports for critical latency devices, such as joysticks. The technology is intended to be cheaper than other WPANs, such as Bluetooth. It requires only about 10 % of the software of a typical Bluetooth or Wireless Internet node. A low power using DEVICE for many wireless applications .

REASONS TO CHOOSE ZigBee:

REASONS TO CHOOSE ZigBee An industry consortium that promotes the IEEE 802.15.4 standard Reliable and self healing. Supports large number of nodes. Easy to deploy. Very long battery life. Secure. Low cost. Can be used globally. Protocol stack: 32KB Number of nodes: 2 64 Range: 1 – 100 m

ZigBee & IEEE 802.15.4 Standards:

ZigBee & IEEE 802.15.4 Standards IEEE 802.15.4 defines the specifications for PHY and MAC layers of wireless networking, but it does not specify any requirements for higher networking layers. Two addressing modes 16 bit (~65,000 devices) 64 bit (lots of devices ) Standard provides 2 PHY options with frequency band as fundamental difference. 868/915 MHz PHY specifies operation at data rates are 20 kb/s and 40 kb/s respectively MAC Layer PHY Layer

IEEE 802.15.4 Specifications for ZIGBEE:

IEEE 802.15.4 Specifications for ZIGBEE Data rates of 250 K bps, 4 0 K bps and 2 0 Kbp s. Support for low latency devices. Dynamic device addressing. Fully handshaked protocol for transfer reliability. Low power consumption. Extremely low duty-cycle (<0.1%) S elf forming network Star, Mesh or Cluster Tree topology models Logical device types Powerful security Symetric key with AES-128 Authentication and encryption at MAC to App. Layers Qualification Platform and profile conformance Interoperability events
