WIRELESS MESSAGE COMMUNICATION BETWEEN TWO IN INDIA

The aim of this project is to develop a system for wireless message communication between two computers using 2.4 GHz trans-receiver units. In offices, communication between employees is essential. This project uses a pair of 2.4 GHz transceiver modules duly powered by 5 volt DC and alarm circuits. They are used for bidirectional real time chat communication from one PC to another wirelessly using hyper terminal. While one of the user attempts to initiate a chat, intimation upon that message is received first by a buzzer sound. There after the other user can start communicating over the chat mode from his PC. A pair of transceiver modules are connected to the PCs using a DB9 (De-Sub) connector and through serial data cord using RS232 protocol communication between the module and the PC. An on-board dedicated ac to dc power supply is used at both ends to power the units. This concept
