Introduction
• This project pertains to short-distance wireless voice communication solution based on ZigBee technology.
• This takes the low power MCU as core control unit, auxiliary by the wireless radio frequency transceiver as well as the audio codec.
OBJECTIVE
To implement the hand-held device for short distance wireless voice communication system based on ZigBee.
ZIGBEE?
ZigBee is the IEEE standard 802.15.4.ZigBee uses the 802.15.4 standard as a
baseline and adds additional routing and networking functionality.
It uses 2.4GHz frequency.Inexpensive batteries in a typical monitoring
application.

Advantages
People can communicate anyone within the organization free of charge for the call.
Low cost High capacityHighly ReliableHighly Secure
THE EXISTING VOICE COMMUNICATION TECHNOLOGY
The following voice communication ways have their application fields respectively, also have the disadvantages such as the high cost, big power loss, inflexible networking and so on.
o Interphone voice communicationo Digital cordless base telephoneo Cellular communicationo Wi-Fi communicationo Satellite communicationIn order to realize a short distance voice communication system to be
nimble, migration facile, low power loss, small scope, low cost and simple, for this purpose we are using voice communication technology based on ZigBee.
