Broadband six-in four-out bridge

Technical Field

The utility model relates to a multiport ultra wide frequency channel bridge overlap joint technical field, in particular to six advances four electric bridges of broadband.

Background

The POI multi-combiner system platform is equivalent to a combiner with higher performance index to specific equipment between the multi-system base station signal source and the indoor distribution system feedback, and has the functions of combining the multi-system base station signal source and outputting the combined signal to the feedback equipment of the indoor distribution system, and simultaneously shunting and outputting the signal from the feedback equipment to each system signal source in the opposite direction.

In the 5G communication system, outdoor location network signals can be covered by respective base stations, and indoor signals can be solved by a conventional indoor coverage system. However, the problems of repeated construction and the like caused by the fact that each operator constructs the own coverage system are more and more prominent.

To address such issues, we propose a solution for a multi-system combiner Platform (POI). The POI product is mainly applied to large buildings and municipal facilities which need to be accessed by a multi-network system, such as large exhibition halls, subways, railway stations, airports, government office organs and other places. The product realizes the multi-band and multi-signal combining function, avoids the repeated investment of the construction of an indoor distribution system, is an effective means for realizing the multi-network signal compatible coverage, and achieves the purposes of fully utilizing resources and saving investment.
