Abstract:
Low-power, wireless, underwater communication devices with communication capabilities without requiring precision underwater navigation. In one aspect, the systems and methods described herein relate to a transmitter which wirelessly transmits data underwater using light-emitting diodes and a receiver which wirelessly receives data emitted from light-emitting diodes using a photodiode. In one embodiment the light-emitting diodes are blue and in another embodiment the light-emitting diodes are red. The receiving photodiode can, for example, be a silicon photodiode. In yet other embodiments the transmitter transmits data to the receiver according to a standard protocol, for example, the IRDA protocol. In one embodiment the transmitter can communicate with receivers as far as 5 to 10 meters away from the transmitter.
