The system is about an atmospheric electro-optical and acoustical communication system which operates among platforms using wireless optical light beam and high frequency acoustic (ultrasonic) waves instead of Radio Frequencies. As the light source, system is using high frequency modulated LED or laser diodes. When environmental conditions are not suitable for the optical communication (e.g. heavy fog), acoustical communication is to take place. Acoustical communication will be done by modulation of the selected ultrasonic frequency.
