Ripple - Communicating through Physical Vibration

Explore a groundbreaking conference talk from NSDI '15 that delves into the innovative concept of communicating through physical vibration. Learn about Ripple, a system developed by researchers from the University of Illinois at Urbana-Champaign, which utilizes vibration motors and accelerometers in mobile phones to transmit small packets of information securely. Discover how this 19-minute presentation covers various techniques such as multicarrier modulation, orthogonal vibration division, vibration braking, and side-channel jamming to achieve transmission rates of up to 200 bits/s using off-the-shelf vibration motor chips and 80 bits/s on Android smartphones. Gain insights into the potential advantages of vibratory communication in scenarios where security is paramount, despite its lower bit rates compared to RF modalities like NFC or Bluetooth.
