MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541121086 A) filed by Nandha Engineering College, Vaikkaalmedu, Tamil Nadu, on Dec. 3, 2025, for 'air waves -sound -based offline communication system.'
Inventor(s) include Dr. D. Vanathi; K. Premkumar; and C. Ranjith Kumar.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The Air Waves system is an innovative sound-based offline communication technology designed to transmit short alert messages without relying on the internet, mobile networks, Bluetooth, or RF modules. The system operates using acoustic beep patterns generated by a transmitter and decoded by a receiver, enabling simple communication in remote, low-network, or emergency environments. Each predefined message is assigned a unique frequency-based tone, which is produced by a microcontroller-driven buzzer and detected by a microphone sensor at the receiving end. The receiver analyzes the sound's frequency and pattern to identify the message and trigger an appropriate response. This method ensures reliable short-range (10-20 meters) communication using low-cost hardware and minimal power. Air Waves is highly useful in disaster zones, forests, tunnels, rural areas, and other network-absent locations. With its simplicity, portability, and energy efficiency, the system provides a practical and affordable solution for essential offline alert communication."
