ZigBee File Transmission

(text, image, audio, video)

Presented by B.SENTHIL KUMAR



Abstract

The aim is to create a wireless interface device thatenables transmission of data files between twocomputers using zigbee wireless radio modems over a

secured wireless communication channel.

The device is capable of transmission of all fileformat such as text, audio, image and video.



Introduction ZigBee is an open technology developed by the

zigbee Alliance to overcome the limitations of Bluetooth and Wi-Fi.

Zigbee protocol is intended for battery operateddevices since it consumes very less power.



ZIGBEE WIRELESS MODEM

The term ZigBee is used to describe a standardized

wireless protocol for personal area networking, or

“WPAN.” The protocol is the work of and property of

the ZigBee Alliance, a consortium of more than 70

companies who have joined together to create and

promote the new standard

ARCHITECTURE OF ZIGBEE



ZIGBEE NETWORK MODEL



PERFORMANCE OF ZIGBEE

Global band operation, 2.4 GHz, 915 MHz, 868 MHz

Unrestricted geographic useRF penetration through walls and ceilings

Automatic or semi-automatic installation

Ability to add or remove devices

Cost advantageous



FEATURES OF ZIGBEE

10 kbps to 115 kbps data throughput

2.10 to 75 m coverage range

Up to 100 collocated networks

Up to 2 years of battery life on standard alkaline batteries



COMPARISON OF ZIGBEE WITH OTHER

WIRELESS DEVICES



.

ZIGBEE APPLICATIONS

Home networking

Industrial control and management

Human and computer interface

Smart dust

Intrusion sensors, motion detectors andglass break detectors.



CONCLUSION

ZigBee can surely fulfill the requirements of

applications having low power consumption along

with low and secured data transfers. It works well for the industrial automation because of

its high number of nodes.

Zigbee protocol is intended for battery operated

devices since it consumes very less power.
