Overview
AirComms is a combined hardware-software system that enables multimedia data transmission over analog radio frequencies. The project won Smart India Hackathon 2022 by demonstrating a novel approach: encoding digital multimedia data into analog-compatible waveforms using Fourier Transform-based encoding and decoding.
The system converts images, audio, and text into frequency-domain representations, transmits them over standard analog radio hardware, and reconstructs the original data at the receiving end. This approach enables data transfer in environments where digital infrastructure is unavailable.
