Mobile communication high-power multi-antenna distribution and coverage method and system

Abstract

The invention provides a mobile communication high-power multi-antenna distribution and coverage method and a mobile communication high-power multi-antenna distribution and coverage system. The system comprises base station amplifier and POI (Point Of Interface) integrated equipment and a low-power multi-antenna coverage system, wherein the base station amplifier and POI integrated equipment comprises a signal separation device, a high-power base station amplifier, an uplink POI and a downlink POI; the signal separation device is connected with the high-power base station amplifier and the uplink POI respectively; the high-power base station amplifier is connected with and the downlink POI; the signal separation device is connected with a corresponding system type base station; the low-power multi-antenna coverage system comprises a plurality stages of passive devices and antennae with the quantity corresponding to the stage number of the passive devices; any stage of passive device is connected with the corresponding antenna; the first stage of passive device on a down link is connected with the downlink POI; the first stage of passive device on an up link is connected with the uplink POI. According to the method and the system, the coverage effect is improved, the engineering construction difficulty is reduced, the manufacturing cost of the system is reduced and the maintenance difficulty is reduced.

Description

technical field [0001] The invention relates to a mobile communication indoor distributed coverage system, in particular to a mobile communication high-power multi-antenna distributed coverage method and a mobile communication high-power multi-antenna distributed coverage system. Background technique [0002] The existing large-scale public building mobile communication distribution coverage projects are generally jointly built and shared by multiple operators, such as figure 1 As shown, multiple base stations of different standards are combined through a POI (Point of Interface, multi-system combination platform), and covered by a power divider and a leaky cable. [0003] However, the traditional mobile communication distribution coverage scheme has the following problems: [0004] 1. In the traditional solution, due to the large POI loss, the coverage area is often limited; and when the leakage cable is used to cover the tunnel and other scenarios, due to the fixed loss o...
