The purpose of this utility model is achieved in that
Wireless signal indoor distributed system antenna is registered one's residence and is covered the notion that needs micropower, beautifies, hangs down radiation, register one's residence and cover the indoor electromagnetic radiation in back in order to reduce antenna, the utility model adopts adjustable power type antenna, the user can transfer the power of turning down greatly to this antenna according to oneself conversation demand and use experience within the specific limits at any time indoor like this, even turn-offs antenna output.The utility model provides the implementation of automatic or semi-automatic change antenna power output, this antenna is in approximate off state when unmanned the use, and can open automatically when having user terminal mobile phone to make a call nearby, for improving the user communications signals service, work as end of conversation, antenna can postpone to get back to approximate off state automatically behind the appropriate time, also can regulate the effect that reaches the minimizing indoor electromagnetic radiation arbitrarily by infrared remote controller, also can be referred to as " low-altitude dish " on commercial the application by the user.
Wireless communication system for the FDD standard, adopt the thinking of uplink band power detecting, antenna input installs automatically controlled electric adjustable attenuator (ATT) additional, and when this electricity adjustable attenuator (ATT) was placed in " ATT=maximum ", input signal was consumed by electric adjustable attenuator (ATT) substantially; It opens control end is the uplink band power detection device (DET) of the wireless communication system of TDMA (Frequency Division Duplexing (FDD)) standard, this DET promptly exports a high level in case detecting is received after there is specific uplink band power in the external world, send into electric adjustable attenuator (ATT) circuit, make electric adjustable attenuator (ATT) attenuation be placed " ATT=0 " state automatically, this moment, input signal just was delivered directly to antenna link from electric adjustable attenuator (ATT) link without any decay; DET is if detect less than specific uplink band power, promptly to electric adjustable attenuator ATT control end output low level, this moment, the promptly automatic section mode with 1dB or 2dB stepping at regular intervals of attenuation of electric adjustable attenuator ATT increased attenuation, until reaching the maximum attenuation value that electric adjustable attenuator ATT sets, make electric adjustable attenuator (ATT) be placed in " ATT=maximum " state again, input signal is consumed by electric adjustable attenuator (ATT) again; Realize the approximate function that automatically shuts down of antenna.
Utilize the uplink band power detecting of the wireless communication system of FDD standard to realize that the switch control to antenna is fully feasible, it is in theory based on following 3 points:
1, the uplink band of the wireless communication system of FDD standard is what to separate with band downlink, and the utility model adopts the filtering device of different frequency range to obtain upward signal easily separately;
2, the public radio communication system user mobile phone of FDD Frequency Division Duplexing (FDD) standard is in the holding state most of the time, its up non-radiating power.
3, domestic aerial is opened back indoor signal reinforcement, and mobile phone switches to indoor initiation again, is abundant on the time, and scheme is feasible.
For the wireless communication system of TDD time division duplex work, can on the said apparatus basis, increase design infra-red remote control start-up circuit, trigger electric adjustable attenuator (ATT) and make it to open and turn-off.
Specifically, the utility model comprises that mobile phone, downstream signal input, electric adjustable attenuator, ascending power detecting amplifier, upward signal select band filter, upward signal reception antenna and service antenna;
Downstream signal input, electric adjustable attenuator are connected successively with service antenna;
Mobile phone is connected with the upward signal reception antenna by airlink, and upward signal reception antenna, upward signal select band filter, ascending power detecting amplifier and electric adjustable attenuator to be connected successively.
The utlity model has following advantage and good effect:
1, makes antenna non-radiating power when the spare time, can reduce significantly the aerial radiation time, reduce the influence of wireless radiation indoor occupant;
2, the work that helps advancing the micropower antenna to register one's residence and cover.
3, be applicable to indoor short distance mobile communication.
