Description of drawings
The above and other feature of the present utility model and advantage will further be described below in conjunction with the accompanying drawings and embodiments, and identical Reference numeral is represented identical feature in the accompanying drawing, wherein:
Fig. 1 is the structured flowchart according to Personal Handyphone System signal cladding system of the present utility model;
Fig. 2 is the circuit diagram according to the low noise linear amplifier in the Personal Handyphone System signal cladding system of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
With reference to figure 1 as seen, Personal Handyphone System signal cladding system 100 of the present utility model comprises:
Directed outdoor active antenna 102 places the moderate position of PHS base station downstream signal intensity, and in the utility model, the position that the Personal Handyphone System signal is strong generally is meant outdoor or window.
Omnidirectional's domestic aerial 104 places the weak position of Personal Handyphone System downlink signal levels, and in the utility model, the weak position of Personal Handyphone System signal generally is meant indoor, and especially high building is indoor.Omnidirectional's domestic aerial 104 links to each other with directed outdoor active antenna 102, and loss coaxial cables is generally used in the connection between them.
The indoor active antenna 106 of omnidirectional places the weak position of PHS mobile phone upward signal level.
Outdoor directional antenna 108 places the position of PHS base station downstream signal transmission direction, links to each other with omnidirectional indoor active antenna 106, and the connection between them generally also is to use loss coaxial cables.
From top description as seen, the utility model has solved the little problem of Personal Handyphone System signal cover by the wired and wireless method that combines.For preparing to be transferred to indoor signal from outdoor reception, directed outdoor active antenna 102 is placed on the moderate position of base station down signal strength signal intensity, it is the outer signal of receiving chamber well, afterwards, this signal is avoided body of wall, floor etc. by the wire transmission of coaxial cable, can effectively reduce the loss of signal, last, by be placed on indoor omnidirectional's domestic aerial 104 with downstream signal to indoor emission.Like this, by omnidirectional's domestic aerial 104 being installed in indoor " blind area " that original PHS base station downstream signal can't directly arrive, come by Wireline (coaxial cable) again and be placed on outdoor directed outdoor active antenna 102 and link to each other, can realize the covering of downstream signal well.For being transmitted into outdoor mobile phone upward signal from indoor, at first receive the mobile phone upward signal by the indoor active antenna 106 of omnidirectional, being connected to Outdoor directional antenna 108 by coaxial cable again launches, be to utilize Wireline to avoid barriers such as wall equally, realize the emission of upward signal to PHS base station direction.
1900MHz frequency range for the Personal Handyphone System use, using the loss of 7D-FB type loss coaxial cables is per 100 meters 21dB, and use the loss of the loss coaxial cables of 5D-FB type is per 100 meters 29dB, considering only needs to use the coaxial cable of about several meters to ten meters length just can walk around wall, so such loss and body of wall loss 13dB noted earlier, every floor plate loss 25dB, performance has had very big improvement.For two passive antennas, omnidirectional's domestic aerial 104 and Outdoor directional antenna 108 require its gain 〉=4dBi, voltage standing wave(VSW) coefficient≤1.3.For two active antennas, directed outdoor active antenna 102 and the indoor active antenna 106 of omnidirectional, 60dB, 65dB, 70dB, 75dB and five kinds of entire gain of 80dB can be provided, and their noise factor≤1.5dB, also comprise low noise linear antenna amplifier in the active antenna of the present invention, this amplifier is used to realize the noise factor of above-mentioned five kinds of entire gain coefficients and requirement, and this can further describe below.Because the radiant power that needs to guarantee two passive antenna places can decide active antenna specifically to select above-mentioned any gain for use according to the PHS signal strength of two active antenna positions and the length of coaxial cable about 10mW.For example, when the field intensity at directed outdoor active antenna 102 places be 48dB μ V (radiant power-65dBm), the cable of selecting for use is a 7D-FB type coaxial cable, 20 meters of length (loss is 4.2dB), need select the gain of active antenna 102 this moment for use is 75dB or 80dB.
