Wireless communication multi-network integrated downlink system

Abstract

The invention provides a wireless communication multi-network integrated downlink system, which comprises a downlink main unit, a plurality of downlink extension units corresponding to the downlink main unit and a plurality of downlink far-end units corresponding to each of the downlink extension units; data are transmitted between the downlink main unit and the downlink extension units by using optical cables; and data are transmitted between the downlink extension units and the downlink far-end units by using optical cables and cable lines. Multi-network signal fusion of internet wireless signals and mobile communication signals and the like is directly realized by adopting a distributed system, a combiner is not needed for external combination, and stability and reliability of operation of a wireless communication downlink information network are effectively improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a multi-network integrated downlink system for wireless communication. Background technique [0002] With the issuance of 3G licenses, all operators are carrying out large-scale 2G and 3G mobile communication network construction to meet the vast voice and data service needs. In the form of networking, the traditional active / passive + coaxial cable distribution method is basically used for indoor and outdoor coverage. [0003] The method adopted in the prior art is to combine two / multiple mobile communication signals into one through a dual-frequency / multi-frequency combiner, and access the same antenna feeder system to realize signal coverage of a multi-network system. [0004] But, also there is following problem in prior art: [0005] First of all, the prior art uses a combiner to jointly build a network. Although it solves the problem of simultaneous access of ...

Problems solved by technology

Other wireless signals used by users still cannot be accessed through traditional co-built networks

[0006] In addition, using traditional network co-construction methods to integrate 2G and 3G signals operated by multiple operators such as GSM, TD-SCDMA, WCDMA, and CDMA2000 requires a large number of tri-frequency combiners for signal integration, which requires multiple systems It can only be realized by wiring separately, and the stability and reliability of network operation are not high.

Because the traditional equipment is generally heavy and the feeder is thick, the construction will cause great damage to the building, so it is difficult to coordinate the property

Moreover, the entire system uses 1 / 2 or 7 / 8 coaxial cables as the signal transmission medium, which not only has high wiring costs, but also is difficult to construct

[0007] In addition, the existing joint construction of each network requires power matching calculations. The design of the scheme is complex, the cycle is long, and the efficiency is low. The expansion needs to be adjusted throughout the network. Once the scheme is formed, it is very difficult to increase the coverage area.
