Abstract
The utility model discloses a combiner system for multi-network sharing in communication. The combiner system comprises a box body and a cover plate, wherein the box body comprises a housing; a plurality of signal input interfaces corresponding to different mobile communication systems are arranged at the front end of the box body; a communal antenna port is arranged at the rear end of the box body; the housing is divided into a plurality of corresponding cavities according to the quantity of the signal input ports; and resonant pillars are arranged in the cavities. The combiner system provided by the utility model is applied to a CDMA (Code Division Multiple Access)/GSM (Global System for Mobile Communications)/DCS (Data Communication Subsystem)shared antenna feed system, and is mainly used for branching and combining signals in different systems, so as to achieve the purposes of saving feed cables, simplifying the system and lowering the cost. Particularly for the CDMA800/GSM900 frequency bands with similar frequencies, the combiner system has the advantages of low insertion loss and good suppression.
Description
[technical field]
The utility model relates to mobile communication equipment, relates in particular to the many nets of a kind of communication and shares the road system of closing.
[background technology]
China's existing mobile communication network has entered the 3G epoch, GSM900/DCS1800 except original China Mobile, the GSM900/DCS1800 of CHINAUNICOM and CDMA800, the PHS of China Telecom, Netcom, WLAN, Digital Clustering and other communication systems have increased WCDMA, CDMA2000, TD-SCDMA 3G system again.The outdoor location network signal can cover by base station separately, and indoor signal can solve by traditional indoor covering system.It is more and more outstanding that yet each operator builds the problems such as repeated construction that covering system brought of oneself respectively.
Particularly communication field in order to utilize original communication infrastructure as far as possible, reduces repeated construction in the networking of multiple different communication standard, saves network investment and operation cost, the common colocation site construction in base station, and antenna system often independently is provided with.If iron tower or roof space are not enough, then be difficult to settle too many antenna; Even can settle, the also corresponding cost that increased has strengthened installation difficulty.
[summary of the invention]
The technical problems to be solved in the utility model provides and a kind ofly the communication signal of many nets different frequency range can be merged and unify to send, and simplifies and installs, and the many nets of the communication that reduces cost are shared the road systems of closing.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, the many nets of a kind of communication are shared the road system of closing, comprise casing and cover plate, described casing comprises cavity, and the casing front end is provided with the signal input interface of the mobile communcations system of 3 corresponding different systems, and the rear end is provided with a common antenna port, cavity is divided into 3 corresponding cavitys according to the quantity of signal input port, is provided with the resonance post in the described cavity.
The operating frequency of 3 above-mentioned signal input interfaces corresponds respectively to 889～960MHz of CDMA800 standard 825～835/870～880MHz, GSM900 standard and 1710～1850MHz of DCS1800 standard.
Above-mentioned resonance post and the as a whole member of casing.
Above-mentioned cover plate is connected with casing by screw.
The utility model is used in the co-space feedback system of many nets different frequency range, and it mainly acts on is that signal to different system carries out a deciliter road, to reach the saving feeder cable, simplified system and the purpose that reduces cost.Special in the approaching CDMA800/GSM900 frequency range of frequency, it is little to have an Insertion Loss, suppresses good advantage.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model embodiment front view.
Fig. 2 is the utility model embodiment vertical view.
Fig. 3 is the utility model embodiment upward view.
Among the figure, 1-casing, 2-inner chamber, 3-resonance post, 4-common antenna port, 5-signal input port, 6-cover plate.
[embodiment]
In Fig. 1, the many nets of a kind of communication are shared and are closed the road system and comprise casing 1 and cover plate 6, casing 1 comprises cavity, be provided with the signal input interface 5 (Fig. 2) of the mobile communcations system of three standards of 3 corresponding separately CDMA800/GSM900/DCS1800 at casing 1 front end, the rear end is provided with a common antenna port 4 (Fig. 3).In cavity according to 3 signal input ports cavity is divided into 3 cavitys 2 in corresponding left, center, right, cavity 2 is designed to the multistage resonant chamber, is provided with resonance post 3 in cavity 2, wherein is provided with adjusting part in the cavity corresponding with CDMA800.3 signal input interfaces, the 5 place cavitys that correspond respectively to the mobile communcations system of three standards of CDMA800/GSM900/DCS1800 are communicated with common antenna port 4 place cavitys respectively.
Resonance post 3 directly is made on the casing, becomes as a whole with casing.
Cover plate 6 is connected with casing 1 by screw.Present embodiment has covered two-layer cover plate, can reach the requirement of degree of protection IP65.
Present embodiment mainly is used in the CDMA800/GSM900/DCS1800 co-space feedback system, and it mainly acts on is that signal to different system carries out a deciliter road, to reach the saving feeder cable, simplified system and the purpose that reduces cost.Special in the approaching CDMA800/GSM900 frequency range of frequency, it is little to have an Insertion Loss, suppresses good advantage.
