ABSTRACT
This project is used to communicate or transmit a text message from one place to another place through wireless i.e, PC to PC communication using wireless technology. The text message is send from PC, which is send by using the Microcontroller and the message is transmitted through wireless technology. At the receiver end the signal is received by the standard receiver and the analog signal was fed to the Microcontroller and then to PC and it was send by the Microcontroller and the message will displayed on PC.
We can use several receivers and the message from the transmitter can be sent to the entire receivers at the same time. 8051 Microcontroller is used to do the above work. It gets data from the PC Keyboard through serial communication and it sends the data out to the RF transmitter which is the encoded signal from encoder.
At the receiver after receiving data pass it on to the decoder which then decodes the signal and gives the bcd output to the microcontroller then Microcontroller send it to the pc through serial communication…
