Abstract
The invention relates to a signal combination system comprising an uplink signal combination platform and a downlink signal combination platform, wherein the uplink signal combination platform comprises a detection module and an uplink combiner; and the downlink signal combination platform comprises a detection module, a PHS/WCDMA (Personal Handyphone System/Wideband Code Division Multiple Access) module and a downlink combiner. The uplink combiner consists of a plurality of stages of high-Q (Quality) cavity combination filters, and the downlink combiner consists of a plurality of stages of high-Q cavity combination filters. The invention solves the problem of the most important combination platform of a passive device in an indoor distribution integrity solving scheme of a building, improves the resource utilization efficiency of an indoor distribution system and reduces the complexity of the system and the building cost by an intensive manner.
Description
Technical field
The present invention relates to a kind of radio communication and close systems technology field, road, particularly a kind of signal closes the road system.
Background technology
For 3G network its data service occur in mostly indoor, therefore, how existingly move, UNICOM, telecommunications, Netcom and the integrated Lu Weiyi cover system that closes of 3G communication system, become the focus that each big operator and equipment integrator pay close attention to.Present mobile communication indoor distribution system need be transformed aspect passive device and begin to adopt in large quantities products such as 3G mixer, support the application that mixes of system such as existing GSM/CDMA/WLAN and 3G system, to reduce the integrated cost of indoor distributed system.The 3G mobile communication is more much bigger than 2G in indoor covering fund input meeting.It is predicted that will there be tens billion of market scales in the market that multi-modulation scheme is closed channel platform equipment.So should take which type of technical measures and scheme to avoid the overlapping investment of system's construction, thereby the fundamental interests of protection operator is the important topic that we face.
This project closes the road system research and development with the mobile communication multi-modulation scheme and industry turns to main contents, research and development mobile communication multi-modulation scheme is closed road system development platform product, make mobile communication in the construction of the evolution of broadband wireless communication technique and mixed networking, in intensive mode, improve the level of resources utilization of indoor distributed system, reduce system complexity and construction cost, solved the channel platform problem of closing of the passive device of most critical in the architecture indoor distribution total solution.The system that is researched and developed has modularized design, and dilatancy is good; Satisfy the individual sexual demand of different system/frequency range; System has the integral monitoring function, and is easy to maintenance; The signal combination loss is little; Power capacity is big; The third order intermodulation performance is good; Can reserve port, characteristics such as convenient upgrading.
Summary of the invention
A kind of signal of the present invention closes the road system, it is characterized in that: this system closes channel platform and downstream signal by upward signal and closes channel platform and formed, and wherein upward signal closes channel platform and includes detection module and up mixer; Downstream signal closes channel platform and comprises detection module, PHS/WCDMA module and descending mixer.Up mixer closes path filter by multistage high-q cavity body and is formed.Descending mixer closes path filter by multistage high-q cavity body and is formed.
In a kind of design of the present invention/channel platform POI (the Point of Interface) scheme of closing that downstream signal separates.This scheme is divided into separately two platforms of transmission of uplink and downlink link signal with POI, it plays to connect the radio communication donor signal and distribute and covers the effect of signal (antenna array and leaky cable), can realize the up and downlink radio-frequency signal of each operator is closed road and shunt respectively, and the interference between each frequency band of filtering effectively.The signal that sends when the mobile phone of different systems collects through antenna and feeder line transfers to up POI, detects the base station of being sent to different operators behind the signal of different frequency range through POI.The major function of POI descender is after the carrier signal of each operator, different frequency range is synthesized, can use same telecommunication cable to transmit, and by the antenna feeder compartment system of overlay area, finishes that the signal in large-scale room area or the tunnel is covered.
Description of drawings
Fig. 1 is that upward signal of the present invention closes the channel platform theory diagram;
Fig. 2 is that downstream signal of the present invention closes the channel platform theory diagram.
Embodiment
Fig. 1 is that upward signal closes the channel platform theory diagram.This upward signal closes channel platform, mainly comprise and include detection module and up mixer, the signal that sends when the mobile phone of different systems is collected through antenna and feeder line transfers to upward signal and closes channel platform, is sent to the base station of different operators after signal closes the signal that channel platform detects different frequency range.
Fig. 2 is that downstream signal closes the channel platform theory diagram.Downstream signal closes channel platform and comprises detection module, PHS/WCDMA module and descending mixer, its major function is after the carrier signal of each operator, different frequency range is synthesized, can use same telecommunication cable to transmit, by the antenna feeder compartment system of overlay area, finish that the signal in large-scale room area or the tunnel is covered.
Claims (3)
