Abstract

The invention provides a combiner/divider, and a method and a system for covering mobile signals of an elevator. The combiner/divider comprises an impedance matching module and a signal coupling module, wherein the impedance matching module is used for carrying out impedance conversion on ascending and descending mobile communication signals; the signal coupling module is used for separating the ascending and descending mobile communication signals which are coupled into corresponding video coaxial cables or corresponding wire telephone twisted-pair cables and used for coupling the ascending and descending mobile communication signals into the corresponding video coaxial cables or the corresponding wire telephone twisted-pair cables. By adoption of the combiner/divider, the mobile communication signals can be coupled into the original video coaxial cables or the original wire telephone twisted-pair cables in the elevator, so special wire-arranging construction is not required during the covering of signals of an elevator cage, and construction difficulty is reduced. Moreover, the arrangement of cables for specially transmitting wireless communication signals in an elevator well is not required, so investment cost is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a combiner and splitter, an elevator mobile signal coverage method and a system thereof. Background technique [0002] With the rapid development of urban construction, there are more and more high-rise residential quarters and high-rise office buildings. my country's residential design code stipulates that elevators must be installed for residential buildings with seven floors or above or residential buildings whose height from the entrance floor of the household to the outdoor design ground exceeds 16m. As a special use environment, the elevator has a thick wall in the elevator shaft, and the elevator car is mostly a metal box. The mobile communication signal attenuation is serious, and the mobile communication signal in and out of the elevator is rapidly fading. Therefore, the general mobile phone signal in the elevator is relatively weak. , or even no signal at ...
