Abstract: Magneto-quasistatic signals may be used to enable under-liquid communication between devices. A magneto-quasistatic signal transmitter of an under-liquid device may transmit a magneto-quasistatic signal conveying communication data through liquid. A magneto-quasistatic signal receiver of another under-liquid device may receive the magneto-quasistatic signal and extract the communication data from the magneto-quasistatic signal. The under-liquid device that received the magneto-quasistatic signal may use the communication data, store the communicate data, and/or relay the communication data (e.g., to another under-liquid device, to an above-liquid device) using another magneto-quasistatic signal.
