Radio frequency communication system

Abstract

The invention provides a radio frequency communication system that is applied to a traffic system of an operation route. The radio frequency communication system comprises a first antenna arranged in a transportation vehicle and a plurality of second antennas that are arranged at the operation route at a predetermined interval. The first antenna and the plurality of second antennas are directional ones; and the plurality of second antennas are oriented to be opposite to the direction of the first antenna. The first antenna carries out radio frequency communication with one antenna, with the highest access signal strength, among the second antennas. According to the invention, the system has the following beneficial effects: the bandwidth is increased; the internet surfing demand can be satisfied when the flow intensity is high during subway running; and the user experience is improved and the like.

Description

technical field [0001] The present invention generally relates to the field of communications, and more particularly, to radio frequency communication systems. Background technique [0002] In recent years, traffic problems have always been a stubborn disease that plagued urban development. In order to deal with the traffic problem, many means of transportation for running lines have emerged, the most representative of which is the underground railway. Underground railway is referred to as subway or subway. In a narrow sense, it refers to an urban railway system or a rapid transit system that mainly operates underground; in a broad sense, because many such systems may also have surface sections in order to match the construction environment exist and therefore generally cover a variety of underground and above-ground high-density transportation systems in metropolitan areas. [0003] As the subway gradually becomes the preferred means of transportation for urban population...

Problems solved by technology

However, the current communication system, especially the transmission speed of the wireless network is not outstanding, and cannot smoothly realize operations such as video calls and high-speed downloads, and cannot meet the growing needs of the masses for wireless communication traffic and speed.

In addition, at present, during the operation of the subway, problems of dropped calls and data mistransmission are often encountered. This is because the wireless network currently installed on the subway track is not stable, and the packet loss rate and bit error rate are relatively high.
