Abstract

The invention belongs to the technical field of communication acquisition, and particularly relates to hotspot acquisition equipment, which comprises a box body, a transceiving antenna, and a power supply module, a baseband processing unit, a remote radio unit, a power amplifier module, a filter and a duplexer which are arranged in the box body, the transceiving antenna is connected with the baseband processing unit in the box body through a feeder line, the remote radio unit is respectively connected with the duplexer and the filter through the power amplifier module, the remote radio unit comprises a plurality of radio frequency subunits which are respectively connected with the baseband processing unit, and each radio frequency subunit is provided with a plurality of radio frequency channels. A BBU+RRU wireless mobile communication macro base station code detection technology is adopted, the transceiving antenna and the feeder line are hung outside, other modules are all integrated in a case and are completely integrated, a baseband board can support transmitting any frequency point in the 1.8 G / 1.9 G / 2.1 G / 2.3 G / 2.6 GHz frequency band, 12 frequency points can be output at the same time, almost all common frequency points in the frequency bands allocated to three major operators by the industrial and information part are covered, and the complex area acquisition rate and the power amplifier conversion efficiency are high.

Description

[0001] This invention is a divisional application of the invention patent with the original application number CN2018110048062, the application date is 2018.8.30, and the invention name is hotspot acquisition equipment. technical field [0002] The invention belongs to the technical field of communication collection, and in particular relates to a hotspot collection device. Background technique [0003] At this stage, small base station technical solutions are mostly used to collect mobile phone signals in areas such as residential areas. Small base stations are mainly used in blind-filling scenarios, and the application scenarios are relatively narrow. However, in the 4G era of high frequency and high bandwidth, small base stations have become an important network component of the fourth-generation mobile communication because of their essence of improving the overall system capacity. Small base stations can be divided into three different types according to their applicat...

Problems solved by technology

The shortcomings of small base stations are mainly the following points: poor concurrent processing capability, the small station solution is generally 32 concurrent channels, and the capacity is small, unable to cope with short-term intensive traffic information collection; poor stability, because the small station is a home base station Derived from "femto", many components of the equipment are not industrial-grade and cannot cope with long-term outdoor operation

Almost all hotspot acquisition devices operate in various uncertain outdoor environments, and work 24 hours a day, 365 days a year. The equipment must adapt to severe cold and heat, high temperature and humidity environments; the output frequency is small, and the small station solution is generally the most Output 6 frequency points, and at this stage with the continuous acceleration of the pace of 4G network construction, the frequency points used by the public networks of the three major operators continue to increase. According to statistics, there are about 10 commonly used frequency points by operators. If the same frequency scheme is adopted, The 6 frequency points cannot meet the collection rate requirements at all; although some manufacturers adopt the macro station technology solution, the integration level is not high and the volume is relatively large, and some manufacturers' equipment cannot even integrate FDD-LTE and TD-LTE From China Mobile, China Unicom and Telecom to integrated collection, even adopt the "back-to-back" installation method during construction, the construction is difficult, and the concealment of the equipment is poor; the efficiency of the power amplifier is low, and the conversion efficiency of the power amplifier of some manufacturers' equipment is relatively low, and the power consumption is large. The peak current reaches 2A, the conversion efficiency of the power amplifier is low, the heat generation is large, and there is a hidden danger of stability, which is not suitable for the main theme of energy saving and emission reduction advocated currently.
