MESSENGER DEVELOPMENT WITHOUT INTERNET
USING ZIGBEE.
AIM:
The main aim of the project is to develop a messenger system by which one can
communicate with more than one, wirelessly using Zigbee technology.
PURPOSE:
The purpose of the project is to implement a messenger where we can chat with other use
without internet facility.

PERSON 1:
2.4 RF waves
Radio frequency (RF) is a rate of oscillation in the range of about 3 kHzto 300 GHz, which
corresponds to the frequency ofradio waves, and the alternating currents which carry radio signals.
RF usually refers to electrical rather than mechanical oscillations, although mechanical RF systems
do exist. Although radio frequency is a rate of oscillation, the term "radio frequency" or its acronym
"RF" are also used as a synonym for radio i.e. to describe the use ofwireless communication, as
opposed to communication via electric wire

DESCRIPTION:
In this project we are implementing a chatting system with out using internet in our
project. Here we are using zigbee technology for communication between two systems. In this
project there are two sections, in first we are having a key board which is connected to the
micro controller using PS2 cable and if a message is sent by this system it should be received
to other system by using zigbee transceiver.
The other system is also connected in the similar manner. In this second section the
zigbee transceiver will receive the signal and sent to the micro controller it will send to the
second system by using PS2 cable with key board.

TECHNOLOGY:
Zigbee is new wireless technology guided by IEEE 802.15.4 Personal Area Network
standard. It is primarily designed for the wide range controlling applications and to replace the
existing non-standard technologies. It currently operates in 868 MHz band at a data rate of
20Kbps in Europe, 914MHz band at 40kbps in USA, and the 2.4GHz ISM bands Worldwide
at a maximum data-rate of 250kbps. It is used to verify whether users truncation is possible
or not. One of the main advantage of this ZIGBEE communication is that it provides a noise
free communication, the amount of noise added in this type of communication is very less
compared to the other wireless communications.
