Embodiment Construction

[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0035] The terms "first", "second" and the like in the description and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of practice in sequences other than those illustrated or described herein.

[0036] Generally, within the coverage area of ​​the leaky cable, from the beginning of the leaky cable (the source access end of the communication system base station) to the end, the strength of the radiated signal is getting lower and lower, and the signal strength between the beginning ...

Abstract

The embodiment of the invention provides a leaky cable control method and a leaky cable, the leaky cable control method comprises the following steps: providing the leaky cable, dividing the leaky cable into at least an initial section, a transition section and a tail section, arranging one or more radiation units in each of the initial section, the transition section and the tail section, arranging the initial section at two ends close to the leaky cable, and arranging the transition section between the initial section and the tail section; and controlling the performance parameters and / or the structure parameters of the radiation units in the initial section, the transition section and / or the tail section, so that the transmission performance of the initial section is superior to that of the transition section and the tail section, and the radiation performance of the leaky cable of the tail section is superior to that of the transition section and the initial section. In this way, 5G signal energy can be evenly distributed in the leaky cable, the levels of the signals from the initial segment to the tail segment are nearly the same, useless consumption caused by too high energy at the initial segment is avoided, the coverage distance of 5G information source equipment can be greatly increased, and the 5G communication wireless coverage problem in long and narrow areas such as subways and high-speed railway tunnels is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for controlling a leaky cable and the leaky cable. Background technique [0002] Leaky coaxial leaky cable is a special coaxial leaky cable that can complete wireless signal coverage while transmitting signals. It has been widely used in 2G / 3G / 4G coverage of subway tunnels and high-speed rail tunnels. The existing leaky cable setting method cannot meet the requirements of 5G communication wireless coverage in narrow and long areas such as tunnels. For example: with the increase of the carrying frequency of 5G communication, the 1-5 / 8” leaky cable used in large quantities cannot support 3.6GHz. At the same time, the increase of carrying frequency also brings additional vehicle body penetration loss, line loss and space loss and other issues. Contents of the invention [0003] Embodiments of the present invention provide a leaky cable control method and the leaky...
