Problems solved by technology

Therefore, at present, each base station or BBU equipment is equipped with a set of GPS antenna systems, and the practice of using multiple sets of GPS antenna systems and multiple feeders at the same engineering site will result in high engineering costs, and will cause the roof, shaft, and off-line of the site. The hard-to-regenerate resources such as holes are occupied in large quantities, resulting in a great waste of resources

Abstract

The invention relates to the technical field of a signal access device, in particular to a GPS signal access device. The GPS signal access device comprises receiving modules for receiving GPS signals,an expansion component, and a multiplex and demultiplex component. The number of the receiving modules is at least two; the expansion component comprises at least one expansion modules; the expansionmodules process and distribute the GPS signals received by the different receiving modules respectively, and each of the expansion modules can be connected to the next expansion module or to the multiplex and demultiplex component; the multiplex and demultiplex component comprises at least one multiplex and demultiplex modules; each of the multiplex and demultiplex modules comprises a multiplex and demultiplex module input port for connecting to the expansion module and at least one multiplex and demultiplex module output port for connecting to an external device. The GPS signal access devicehas a cascade structure and a backup function, so that the capacity can be increased and the reliability can be improved.

Description

technical field [0001] The invention relates to the field of signal access devices, in particular to a GPS signal access device. Background technique [0002] At present, CDMA (Code-Division Multiple Access, Code Division Multiple Access) and TDD-LTE (TimeDivision Duplexing Long Term Evolution, Time Division Duplex Long Term Evolution technology) base stations or BBU (Building Base band Unite, indoor baseband processing unit) equipment need Obtain an accurate clock source to ensure synchronization. For this reason, each base station or BBU device needs to be equipped with a GPS antenna system. At the same time, a very long feeder line needs to be laid to connect the GPS receiving antenna installed in the GPS antenna system on the roof. Connect with the base station or BBU equipment in the equipment room. With the rapid development of mobile communication technology, especially the large-scale commercial use of 4G, TDD-LTE base stations are widely used, resulting in an incre...
