This document presents a project proposal for a short-distance wireless voice communication system using ZigBee sensors. The objectives are to implement a handheld device for voice communication using ZigBee. It describes the ZigBee technology, provides a block diagram of the transmitter and receiver components, and outlines the advantages as low cost, high capacity, reliability and security. It presents a timeline for the project in 5 phases over 12 months and estimates the total project cost to be around $23,200.

- 4. 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.
- 5. OBJECTIVE To implement the hand-held device for short distance wireless voice communication system based on ZigBee.
- 6. 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.

- 8. Advantages People can communicate anyone within the organization free of charge for the call. Low cost High capacity Highly Reliable Highly Secure
- 9. 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 communication o Digital cordless base telephone o Cellular communication o Wi-Fi communication o Satellite communication In 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.
