Maritime wideband wireless communication system

Abstract

The invention discloses a maritime wideband wireless communication system which can realize broadband wireless communication among moving ships on the sea surface and solve the problems that the communication bandwidth is narrow, the communication distance is short, the communication chain is unstable (a ship body shakes) and the like when the existing communication system is used among the ships on the sea surface. The maritime wideband wireless communication system mainly comprises a set of central station and multiple sets of mobile stations, wherein the central station and the mobile stations are respectively mounted on different ships, the ship on which the central station is mounted can be communicated with any ship on which one mobile station is mounted. The central station and the mobile stations are same in structure and respectively comprise an antenna, an outdoor unit, an indoor unit and a network switch. For meeting the requirements of remote and wideband transmission under a specific environment of the sea surface, the emitting efficiencies of the antennas in the system are within a frequency range of 430 MHz to 860 MHz; and for resisting the storm wave swinging on the sea surface and guaranteeing the stability of communications links, omnidirectional antennas having receiving and transmitting functions are used as the antennas in the system, and two antennas with same performances form a V shape.

Description

technical field [0001] The invention relates to a marine broadband wireless communication system, which belongs to the technical field of wireless communication. Background technique [0002] The demand for broadband wireless communication at sea has promoted the development of broadband wireless communication at sea. From the current situation, the application of broadband wireless communication at sea can be divided into three types: the first category, broadband wireless communication between islands and continental shelves, communication The equipment at both ends is fixed, and this equipment is mainly to meet the needs of residents on the island for various network communications. The second category is the wireless communication between near-shore and mobile ships. The near-shore equipment is fixed on the top of the mountain near the sea. The mobile ships are large ships, and the height of the antenna is relatively high. This type of equipment is mainly to meet the bro...
