Background
In recent years, the mobile communication technology of offshore and terrestrial has been rapidly developed, and the bandwidth, data transmission rate, stability and coverage of the communication have been significantly improved, however, most of the mobile communication technologies are designed for land-based communication, so that most of these high-quality communication service networks are installed in the terrestrial, especially urban, environment. The characteristics of relatively small coverage and reliance on ground base stations greatly limit its use in ocean communications.
The most important communication mode for guaranteeing various global ocean activities is the offshore satellite communication technology at present, wherein the international maritime satellite system and the iridium satellite system are most widely applied. However, a considerable part of the users have high demands on their transceiver devices, and there are problems of high cost, high delay and low communication rate. The latest fifth generation maritime satellite system supports a downlink rate of 100Mbit/s and an uplink rate of 5Mbit/s at the highest, and the channel capacity is still too small for the huge data volume of the offshore mobile network. Furthermore, existing satellite communication systems do not enable signal coverage all over the sea and all over the day.
Shore-based communication technology and offshore satellite communication technology do not meet the communication requirements of ocean regions well, which means that there is still no absolutely reliable means of communication for humans in the vast sea. In view of the current situation in which most of the trade relies on marine transportation and the urgency of maintaining marine rights today, there is a strong need for reliable and wide-coverage communication networks.
