Mobile device with an underwater communications system and method
First Claim
1. A communications system comprising:
- a data input;
a modulator, for modulating data onto a carrier signal;
a transmitter, anda remote receiver,wherein the transmitter is provided with an antenna for transmitting modulated electromagnetic and/or magnetic signals to a remote receiver and at least one of the transmitter and/or remote receiver is housed in a portable communications unit, for use by a user, the portable communication unit having a user interface with at least one input selection element, whereby the portable communications unit is placed in a fluid propagating medium such that at least a part of a signal path between the transmitter and remote receiver is through the fluid propagating medium.

Abstract
An underwater communications system is provided that transmits electromagnetic and/or magnetic signals to a remote receiver. The transmitter includes a data input. A digital data compressor compresses data to be transmitted. A modulator modulates compressed data onto a carrier signal. An electrically insulated, magnetic coupled antenna transmits the compressed, modulated signals. The receiver that has an electrically insulated, magnetic coupled antenna for receiving a compressed, modulated signal. A demodulator is provided for demodulating the signal to reveal compressed data. A de-compressor de-compresses the data. An appropriate human interface is provided to present transmitted data into text/audio/visible form. Similarly, the transmit system comprises appropriate audio/visual/text entry mechanisms.
