UNDERWATER COMMUNICATION SYSTEM
First Claim
1. An underwater communications network system comprising a plurality of communication stations, each communication station comprising:
- a transceiver including at least one transmitter and at least one receiver, saidat least one transmitter comprising;
a data input;
a modulator, for modulating the input data onto a carrier signal; and
an antenna for transmitting modulated electromagnetic and/or magnetic signals to a remote receiver, andsaid at least one receiver comprising;
an antenna for receiving modulated electromagnetic and/or magnetic signals,wherein at least one transceiver is underwater.

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.
