Description
Technical field
The utility model relates to the integral mechanical structure of communication equipment, is meant the integral mechanical structure of mobile communication small base station in the communications field especially.
Background technology
Along with the construction of the extensive commercial network of TD-SCDMA, the wide covering of base station has been proposed more and more higher requirement, the problem of indoor covering is also more and more outstanding, realizes that at present the mode of indoor covering mainly contains three kinds:
First kind: provide indoor covering in the overlay area by outdoor macro base station.Macro base station mainly is made up of MU (Main Unit, main control unit) and RRU (Remote Radio Unit, far-end radio-cell) two parts.MU comprises base station master control and Base-Band Processing; RRU then comprises wireless radiofrequency Transmit-Receive Unit and power amplifier unit; Be connected by optical fiber between RRU and the MU, realize that abundant flexibly wireless networking covers scheme, but adopt that this base station can't produce that inter-user interference, electromagnetic wave shielding are poor at indoor employing smart antenna, single channel, complicated integral structure, volume is big, cost is high, sometimes special-purpose machine room need be set in building, dispose dumb.If guarantee the quality of indoor covering, outdoor interference will become and be difficult to control, influence the integrated planning and the capacity of network.In addition, because the operating frequency of 3G is higher, for depth bigger market and recreation center, it is impossible covering by outdoor base station.
Second kind: exist at outdoor base station under the situation of capacity more than needed, with wireless mode outdoor signal is introduced indoor coverage hole by the repeater.The repeater by donor antenna pickoff signals from existing overlay area,, is transmitted into the signal of filtering once more after power amplifier amplifies and treats the overlay area isolating with logical outer signal by band pass filter in down link; In the uplink road, the signal of the travelling carriage mobile phone in the overlay area is transmitted into corresponding base station with same working method after by up amplification link processing, thereby reaches the signal transmission of base station and mobile phone.This base station can produce problems such as inter-user interference, electromagnetic wave shielding are poor, single channel at the indoor smart antenna that can't adopt too.
The third: the place in that telephone traffic is concentrated, indoor little base station is set, solve covering and capacity problem simultaneously.Utilize little base station to solve indoor problem and have significant limitation, little base station of using is not supported smart antenna substantially at present, can only support common antenna, can produce problems such as inter-user interference, single channel so too, and equipment input and the construction period of building little base station are all bigger, only are adapted at high-grade conference hall or market use that telephone traffic is concentrated.
According to above introduction, present macro base station, all there is the indoor inter-user interference that can't adopt smart antenna and produce in site type such as repeater and little base station, single pass inferior position problem, and complicated integral structure, volume is big and cost is high, and problems such as special-purpose machine room need be set in building, therefore be necessary very much to design and aly can realize that indoor multichannel disturbs and isolate, reduce system interference, flexible configuration and lower-cost small base station, cover and capacity to satisfy to change according to demand to dispose flexibly, solve the problem of covering and capacity planning interwoveness, make that the planning of covering and capacity is relatively independent, help system's expansion in future.
