Description
Affiliated technical field
The utility model relates to a kind of TD-SCDMA mobile communication wireless repeater.
Background technology
Base station equipment is the capital equipment that the TD-SCDMA wireless access network is built, and can be simultaneously covers and capacity for the user of the area of coverage provides by mounted base station.For zones such as the sparse rural area of population, highway, railways, the covering of base station is subjected to the influence of topography, can't enlarge, and causes the capacity utilance very low; Have only by the relaying amplifying technique, overcome the influence of geogen, could improve the utilance of base station capacity, reduce cost of investment.
Summary of the invention
The purpose of this utility model is that a kind of TD-SCDMA mobile communication wireless repeater will be provided, and it helps the user realizes quick networking and reduce the network investment cost, and each base station capacity is fully played, and obtains more wide covering.
The utility model is to constitute like this, it is characterized in that: it comprise donor base station transceiver and antenna for base station, with repeater reception antenna, repeater primary module and the retransmitting antenna of repeater of antenna for base station wireless link with relaying enlarging function.
During work, the utility model can carry out transmitting and receiving of mobile communication signal with the antenna of base station transceiver on the one hand, simultaneously on the other hand, can carry out transmitting and receiving of mobile communication signal by retransmitting antenna and mobile phone again, thereby realize more wide covering.
Than existing base station device, remarkable advantage of the present utility model is:
1, helps the covering of the signal of communication of giving full play to and realize the remote cell territory of each base station capacity, thereby reduce operator's investment.
2, the outdoor equipment investment is little, and instant effect is set up the TD-SCDMA network fast for new operator advantage is provided.
Below in conjunction with drawings and Examples the utility model is specifically described.
Description of drawings
Fig. 1 is a normal cellular networking network structure.
Fig. 2 is a networking network structure of the present utility model.
Fig. 3 is the theory diagram of utility model.
Fig. 4 is the networking network structure of case study on implementation.
As shown in Figure 3, structural feature of the present utility model is:
(1) described mobile communication base station is the TD-SCDMA base station, and the radio frequency signal frequency of donor base station is: 2300-2400MHz/2010-2025MHz/1880-1920MHz.
(2) described repeater equipment includes switch power module, monitoring module, RF-IF module, mobile module and filter, equipment need to select amplifying signal with the external signal that receives by the filtering of filter, amplify output by the RF-IF module then, launch by exterior aerial; The radio frequency signal frequency of mobile phone terminal emission simultaneously is 2300-2400MHz/2010-2025MHz/1880-1920MHz, transmitting antenna by the repeater receives, pass through filter, carry out the filtering of signal frequency after the RF-IF module is amplified again again by filter, send back the receiving terminal of base station then by the on-air radio link.
(3) transmitting power of described mobile communication wireless repeater is 0.1---10 watts.
As shown in Figure 3, operation principle of the present utility model is:
The uplink and downlink signal is amplified:
Down link (base station is to mobile phone): the radiofrequency signal 2300-2400MHz/2010-2025MHz/1880-1920MHz of base station output, through the antenna for base station emission, the aerial received signal of the reception antenna of repeater, through amplifying output by the RF-IF module behind the filter filtering, realize that by transmission antennas transmit downstream signal covers at last.
Up link (mobile phone is to the base station): mobile phone terminal output radiofrequency signal 2300-2400MHz/2010-2025MHz/1880-1920MHz, transmitting antenna by the repeater receives, through exporting behind the amplification of RF-IF module, the filter filtering, after the base station is sent in the reception antenna emission back to.
As shown in Figure 4, the networking network structure of the utility model embodiment.
Its characteristics are: the base station can connect a plurality of wireless discharging-directly stations by many airlinks, realizes the covering to a plurality of zoness of different.For example: as the comparatively remote village, small towns of signal source, the covering of small-sized indoor covering system, covering main line of communication or the like.
Main feature of the present utility model: support 3G (Third Generation) Moblie standard TD-SCDMA; Operating frequency: 2300-2400MHz/2010-2025MHz/1880-1920MHz; Be applied to rural base station and enlarge coverage rate, cost is low, networking is quick.
The utility model is not only novel, and is reasonable in design, and equipment manufacturing cost is low, and effect is good, and its market prospects are considerable.
