Description

TECHNICAL FIELD

At present, mobile communication has become an indispensable and most commonly used way for people to communicate with the outside world, and its terminal devices have almost spread to everyone, with the most widely used being mobile smartphones. How to effectively, safely and conveniently transmit the electromagnetic wave signals of an intelligent mobile terminal brought underwater to the water surface and directly to the Internet and other general communication systems has become a new problem.
