UNDERWATER COMMUNICATION USING ELECTRONIC DEVICES

Abstract:

Methods and devices may be used to perform underwater communication using one or more electronic devices. The one or more electronic devices include a first wireless transceiver configured to transmit first wireless signals through an air medium with the first wireless signals not being conducive for transmission through a water medium. The one or more electronic devices also include a second wireless transceiver configured to transmit second wireless signals through water. The electronic devices detect whether at least one electronic device has been submerged, and in response to submersion, transmits at least some communication types from the second wireless transceiver rather than the second wireless transceiver.
