Description
Technical field
The present invention relates to wireless communication fields more particularly to a kind of in-door covering to configure system.
Background technique
In the prior art, in-door covering configuration divides device by using room, by information source power reasonable distribution to end antenna
It is exported, common room divides device to include power splitter (including two power splitters, three power splitters etc.), coupler etc..Wherein function point
Device is the power equal part for that will input, and coupler is the power not equal part for input.
Existing in-door covering configuration design selects different function generally according to the actual demand of each point power in scene
Rate, generally for general building, multiselect installs a coupler with each floor, and the coupler of trunk roads is using the side concatenated
Formula.Shown in Figure 1, information source passes through first order coupler and what is be connected with coupler divides function coupler, power splitter etc. that will export
Power transmission to end antenna.Source signal often passes through a room and divides device, and the power of signal can all send faint decaying,
Therefore, with the decaying of source signal power, the lower coupler of power level is selected away from the farther away coupler of information source.In figure
Dotted line frame in third, the 4th coupler be respectively 15dB, 10dB coupler, and divide function coupler, two function by the two poles of the earth
After signal after point device is sent to end antenna, power can decay more, and only send by the signal of a fraction function coupler
To the antenna of end, power attenuation is fainter, therefore causes two end antenna output signal power differences in figure larger,
There are jump, the signal for eventually leading to two floors is had differences, and not can guarantee the efficiency of transmission and speech quality of signal.And
In-door covering in the prior art configuration is all using the structure of concatenation, and the device of each concatenation is generated due to factory design
Certain performance error will accumulate, therefore large error is be easy to cause in end antenna, if any one device hair in concatenation
Raw failure or performance decline, can all influence the operation of whole system, thus whole system not there is only large error, have larger peace
Full hidden danger, there is also the power difference of different floors is larger, signal power is unbalanced, not can guarantee effectiveness and logical
Talk about quality.
