Technical Field

Background
The demand for 5G communication network coverage is increasing with the sea area. Currently, telecommunication equipment manufacturers propose 5G-based ultra-far coverage schemes, and through test verification, the coverage distance can reach hundreds of kilometers.
Then, the above coverage scheme can only effectively cover areas such as a ship deck and a cab, and as the ship structure adopts metal materials such as steel and the like and the cabin is positioned at the bottom layer of the ship, the 5G signal cannot reach the cabin in a penetrating, diffracting and other modes, so that the cabin becomes a blind area or a weak area covered by the 5G signal.
Referring to fig. 1, one way of solving the problem of signal coverage in the cabin in the prior art is to use CPE (Customer Premise Equipment) equipment, and the CPE can convert the 5G signal into a WiFi signal, and support the mobile terminal to access the network through WiFi.
However, the approach to solving the problem of signal coverage in the cabin by CPE has the following drawbacks:
(1) In the weak coverage area of the base station, the user experience through WiFi access is poor due to the fact that the information source signal is weak;
(2) When the base station is covered in a long distance, the problem of limited uplink power exists in a CPE coverage mode;
referring to fig. 2, another way to solve the problem of signal coverage in the cabin in the prior art is to use a wireless relay device, where the wireless relay device performs 5G signal coverage on the cabin after performing amplification filtering processing on the 5G signal, so as to solve the problem of limited uplink power during 5G signal coverage and long-distance coverage in the cabin.
However, the way to solve the signal coverage problem in the cabin by the wireless relay device has the following drawbacks:
(1) Due to the low permeability of the 5G terminal, part of non-5G terminals cannot access the network;
(2) The wireless relay device only supports the frequency band of a certain operator, so that the 5G terminals of other operators cannot access the network.
