Abstract: An underwater acoustic communication system for a mobile electronic device, such as a smartphone, has a communication unit with one or more ultrasonic transducers to transmit and receive underwater ultrasonic signals. The communication unit is connected to an audio auxiliary interface of the mobile electronic device. A processing unit in communication with the auxiliary interface receives RF signals from and transmits RF signals to the communication unit via the audio auxiliary interface.

Abstract: Embodiments disclosed herein may be implemented in the form of a method or corresponding apparatus for receiving or transmitting network communications carried at acoustic wavelengths via an acoustic medium. The corresponding method or apparatus may include a gate-level digital hardware module communicatively coupled to a communications module and define therein logic blocks configured to perform respective primitive processing functions, sequences of the logic blocks being capable of processing data units in accordance with any of the multiple communications protocols on a data unit-by-data unit basis without reconfiguring. According to some embodiments, the gate-level digital hardware module may be configured to process a data unit in accordance with a first communications protocol by directing the data unit through a first sequence of logic blocks, and process a subsequent data unit in accordance with a second communications protocol by directing the subsequent data unit through a second of sequence logic blocks.

Abstract: A visible light communication (VLC) system transmits and receives visible light signals across a VLC channel that includes an air-water interface. A transmitter may be configured generates and transmits a visible light signal across the VLC channel to a remote device, and a signal modulator controls the transmitter to generate the visible light signal from a digital transmission signal in accordance with a modulation setting. A receiver processes a remote visible light signal received across the VLC channel from the remote device. A signal demodulator converts the remote visible light signal to a received digital signal.
