The covering of signal can be directly affected.However, being built more than antenna-feedback system using passive device, do not possess work
Make state self monitor and alarm function.So, the running status of antenna-feedback system how is monitored, becomes one
The individual new problem for being badly in need of solving.At present, antenna-feedback system is detected, special messenger can only be sent to carry special
Instrument is reached the spot, and indoor distribution antenna-feedback system is taken apart paragraph by paragraph and detected.On the one hand this method expends
Substantial amounts of manpower and materials, and do not accomplish monitoring in real time.Therefore, indoor distribution antenna-feedback system how is realized
Quick and precisely monitor, the key point as lifting indoor communications quality.
At present, outdoor positioning system has global positioning system (GPS, the Global Positioning in the U.S.
System), the Galileo of Russian glonass system, the dipper system of China and Europe.In outdoor
Using the satellite fix advantage such as have wide coverage, user's access amount big.But when user enters interior
When, the positioning precision of these alignment systems just drastically declines.Indoor barrier is primarily due to signal
Influence.So, the problem of in order to solve indoor positioning, derive multiple indoor alignment system and method.Often
Indoor positioning technologies have Wireless Fidelity (WI-FI, Wireless Fidelity) technology, radio frequency identification, indigo plant
Tooth positioning, infrared ray indoor positioning technologies etc..Bluetooth location technology coverage is wider, and has necessarily
Communication capacity, and the handhold mobile terminal equipment such as mobile phone of a new generation has all supported the technology of bluetooth 4.0.Therefore,
Low-power consumption bluetooth technology has become the one preferred technique of indoor positioning.
For the problem and the problem of indoor positioning of the room of solution point antenna-feedback system monitoring, it is currently suggested following
Several solutions.
