INTRA-SHIP RADIO COMMUNICATION METHOD Russian patent published in 2015 - IPC H04B7/00 

FIELD: radio engineering, communication.

SUBSTANCE: signals from user devices are received by an antenna mounted on the upper deck of a ship and by an integrated territorially distributed antenna consisting of sections of a transmitting cable laid on the middle and lower decks of the ship; signals emitted by the sections of the transmitting cable are received by radio-frequency combiners which perform division, depending on the frequency range, into signals in the 2400-2500 MHz range, which are transmitted via radio-frequency cables to Wi-Fi access points, and signals in the 450-470 MHz range, which are transmitted to a TETRA base station; signals from the antenna mounted on the upper deck of the ship are also divided into signals in the 2400-2500 MHz range and are transmitted via radio-frequency cables to Wi-Fi access points, and signals in the 450-470 MHz range, which are transmitted to a TETRA base station; converted signals from the Wi-Fi access points and the TETRA base station are transmitted via an Ethernet line to a switch.

EFFECT: enabling transmission of different information to different ship systems and between user devices.
