The data communication is highly essential in the military field and especially critical during Battles. This is to protect any confidential data from the enemies. The PC encrypts the given data into pseudo random noise sequence using OFDM and Blowfish Algorithm. The communication takes place through wireless RF transmitter and receiver module operating at a frequency 433.92MHz. At the receiving end PIC Microcontroller is used to decrypt the receiver data into original text data. Ones the message is received the alarm indicates, so that one can know that some message is received.
