Electrically tunable intelligent 3G antenna
Now, under the angle of intelligent 3G antenna network selection selects the method for preset declination and associated mechanical tilt adjustment to the 3G antenna. Although this method can satisfactorily cover the request, but in practice also exposed some mechanical tilt angle to overcome the defects, such as adjusting the angle of difficult, in network optimization project, needs to consume a lot of manpower capital, low power conditioning; because of the mechanical downdip sites in shade engineering cover, shade reservation under large angle space conditioning, form a huge volume in the shade project; large point horizontal plane covered downdip distortion, and along with the polarization and polarization characteristics of the main cross level variation, and no downward trend before and after than when not common etc..
It is precisely because of the practice of smart 3G antenna there are these shortcomings, the development and application of intelligent 3G antenna will inevitably become one of the important trends in the future TD-SCDMA smart 3G antenna. Electrically tunable smart 3G antenna has the following advantages:
A series of dynamic adjustment can end beam angle optimization, network dynamic real-time adjustment does not need close station, opposite can timely balance of concealment, capacity, interference etc.;
In the structure of the vertical device, without considering the declination of the space reserved device is simple and reliable, and easy to beautify;
Keep adjusting the site monitoring database 3G antenna beam data and historical data, easy to contact the remote monitoring analysis and optimization of network cover.
