Description
Technical Field
The utility model belongs to the communication system field, concretely relates to take 5G signal elevator cover system of CPE function.
Background
With the rapid development of mobile communications, mobile users are growing rapidly, and the requirements for traffic density and coverage of mobile signals are also continuously rising. However, the development of cities also leads to more and more high-rise buildings, which have large scale, good quality and strong shielding effect on mobile signals. In the elevator of a large building, because the wall body of an elevator hoistway is thick and heavy, an elevator car is mostly a metal body, signal attenuation is serious, mobile communication signals are weak, a mobile phone cannot be normally used, a blind area and a shadow area of mobile communication are formed, and a network operator is required to specially perform network optimization for covering the elevator.
The 5G era is coming and major operators worldwide are actively exploring the 5G network construction, where elevator coverage is considered as the high-value core of mobile networks. The frequency of 5G is higher compared with 3G/4G, and the higher frequency means larger transmission loss and penetration loss, which inevitably causes more signal weak areas and blind areas of the 5G signal in the elevator car.
Existing elevator coverage generally falls into two broad categories.
The first type is 2G/3G/4G operator network coverage. The method mainly comprises a traditional distribution system covering mode, a traveling car covering mode and a well top wireless covering mode.
In the traditional distribution system covering mode, 2G/3G/4G wireless signals of an operator are introduced into an elevator shaft through a radio frequency feeder cable, and a set of covering antennas are arranged on the elevator shaft every 3-4 layers to complete wireless covering of the elevator shaft and an elevator car. The covering mode is mature in technology, but the construction difficulty of the engineering in the shaft is large. In addition, the frequency of the 5G signal is high, and the passive devices used by the traditional distribution system cannot meet the requirement.
The accompanying elevator car covering mode receives a base station signal from the top of an elevator shaft, sends the signal to relay equipment installed on an elevator car, amplifies the wireless communication signal and then completes signal covering on users in the car through a covering antenna. The covering mode is stable in covering signal, but the traveling cable needs a plurality of wire clamping devices, the installation and maintenance difficulty is high, and certain potential safety hazards exist in normal up-and-down operation of the elevator car by the traveling cable.
The well top wireless coverage system consists of active signal amplification equipment and a forwarding antenna which are installed at the top of a well. The active signal amplification equipment receives wired or wireless signals from the base station, performs amplification control processing on the signals, and then transmits the amplified signals downwards along the elevator shaft in a wireless mode through the forwarding antenna to complete signal coverage of the elevator shaft and the elevator car. The covering mode is simple in engineering installation and has a good covering effect on the low-rise elevator. However, for high-rise elevators, when the elevator car is at a lower floor, the elevator car is far away from the forwarding antenna, the wireless signal in the elevator car drops seriously, and even the signal of the forwarding antenna cannot be received.
The second type is WiFi signal coverage. The Wifi signal is mainly used for receiving background data or files by an advertisement screen in an elevator maintenance or an elevator car. The Wifi signal coverage system is composed of a receiving antenna installed on the top of the elevator car, CPE equipment and a Wifi coverage antenna. Wherein receiving antenna 61 receives the operator wireless signal in elevator well 1, converts wifi signal into through CPE equipment 62, covers antenna 63 again and carries out wifi signal cover in elevator car 2 through wifi to accomplish uploading or down sending of elevator dimension guarantor data or elevator advertising information. This wifi signal coverage mode is limited to the operator wireless signal coverage condition in the elevator well 1, can not guarantee the timely upload and download of information.
At present, the industry generally considers that the 5G small base station is a main solution for 5G indoor coverage, but the 5G small base station has the problems that optical fibers cannot be in place, engineering construction difficulty is high, cost is high and the like in the elevator deployment process. In addition, at the initial stage of 5G network construction, the cost of the 5G hand-held terminal is higher, and many users can not enjoy the network advantage of 5G in time on the premise of not changing the cell-phone, and the 5G CPE terminal can convert the 5G signal into a wifi signal and provide the wifi signal for the existing hand-held terminal user to use, but the 5G CPE terminal can also be unable to use because of the received signal problem in the elevator.
