Excuse me, is there a wireless network and cell phone signal on board when you go out to sea?

There are wireless networks and cell phone signals on board. But members are prohibited from overusing it.

Seafarers work in the sea, but they haven't been on land for many years, so they will be very lonely at sea, because they can't play computer and watch TV with their mobile phones. If there is no signal, there will be a certain number of deaths, and most of them will fall in.

Obviously, there will be no signal tower above the ocean, so ordinary mobile phones have no signal. Sailors and crew members use maritime communication satellite phones, and radio signals are relayed to civil communication networks through satellites to realize network interoperability. In principle, maritime communication satellite phones can access the Internet.

Extended data:

The traditional navigation mode of GPS+ chart is gradually changing to intelligent navigation service, and the demand for serving intelligent ships in the future will completely change the existing traditional navigation service mode.

VHF system in shore-based communication system can no longer meet the growing demand of maritime security information development. At present, maritime users are eager to integrate and simplify a variety of radio communication equipment. The emergence and characteristics of broadband wireless network technology have laid a good foundation for the realization of the above goals.
