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.

Embodiment Construction
[0041] The following description presents many different embodiments, or examples, for implementing different elements of the invention. Specific examples of components and arrangements are described below to simplify the present disclosure. Of course these are merely examples and are not intended to be limiting. Furthermore, the following description of a first component formed on a second component may include embodiments in which the first and second components are formed in direct contact, and may also include embodiments in which additional components are formed inserted into the first and second components An embodiment such that the first and second components are not in direct contact. Various features may be arbitrarily drawn in different sizes for simplicity and clarity.
[0042] The gist of the present invention is, by applying the 5G bridge antenna and setting it in a relative direction, that is, making the antenna set in the vehicle completely opposite to the an...

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 communication, and more particularly, to a radio frequency communication system. Background technique [0002] In recent years, traffic problems have always been a stubborn disease that plagues urban development. In order to deal with the traffic problem, many means of transportation that run the line came into being, the most representative of which is the underground railway. The underground railway is referred to as the subway or the subway. In a narrow sense, it specifically refers to the urban railway system or MRT system that mainly operates underground; in a broad sense, because many such systems may also have ground sections in order to match the built environment exist and thus generally cover a variety of underground and above-ground high-density transportation systems in metropolitan areas. [0003] As the subway has gradually become the preferred means of transportation for the urban...
