Dynamic antenna adjustment and communication method by utilizing shore-based base station and ship location information

Abstract

The invention discloses a dynamic antenna adjustment and communication method by utilizing a shore-based base station and ship location information, and mainly solves the problems that in a ship and shore-based wireless network, the shore-based base station and the ship serviced by the base station both use directional antennas, so that in the neighborhood discovery phase, the shore-based base station and the ship serviced by the base station cannot find each other and further cannot perform communication. The dynamic antenna adjustment and communication method comprises three steps of establishing connection, calibrating the shore-based base station and calibrating the ship serviced by the base station. The dynamic antenna adjustment and communication method disclosed by the invention is suitable for the dedicated ship and shore-based wireless network of the directional antennas arranged on the shore-based base station and the ship, simple in antenna adjustment method, and capable of realizing communication between the shore-based base station and the ship at the near-shore channel.

Description

technical field [0001] The invention relates to ship shore-based wireless network communication, in particular to a method for dynamic antenna adjustment and communication using shore-based base station and ship position information. Background technique [0002] The ship's shore-based wireless network is an important part of the marine Internet, which is mainly responsible for extending the high-quality and high-bandwidth Internet wirelessly onshore to the ships in the coastal waterway 5 kilometers to 30 kilometers offshore. [0003] At present, the research of ship shore-based wireless network is still in its infancy. The main reason why the research on ship shore-based wireless network is relatively late is that people who work and live on ocean-going ships have become accustomed to the boring life in the process of sailing. In special cases, for example, after encountering pirates, ship collisions, and irresistible natural disasters, satellite communications are reluctan...

AI Technical Summary

Problems solved by technology

In addition, through the AIS and satellite system, the sending and receiving parties using directional antennas provide information about each other, which effectively solves the problem that in long-distance communication, because the sending and receiving parties use directional antennas at the same time, they cannot find each other in the neighbor discovery stage.
