SMART RF SIGNAL QUALITY ENHANCEMENT SYSTEM FOR MOBILE DEVICE WITH ACTIVE DYNAMIC RADIATION PATTERN ACHIEVED BY SENSING DEVICE PROXIMITY ENVIRONMENT WITH PROPERTY, POSITION, ORIENTATION, SIGNAL QUALITY AND OPERATING MODES

摘要

The smart RF signal quality enhancement system is a design and technique to improve the signal quality of wireless mobile device with active dynamic radiation pattern approach manipulated by RF/Antenna system that mainly works by scanning and detecting the change in device proximity environment with property & position sensing, device orientation, user head & hand hold effect, signal quality parameters and operating modes to vary the radiation pattern. The mobile devices are handled in different proximity environment which causes electromagnetic interaction that can leads to degradation in signal quality based on the nature of the vicinity environments. So when the signal quality degrades the system will sense, compute and vary the radiation pattern accordingly to enhance the signal quality. The system design consist of (a) a sensor system 130 to determine the change in proximity environment with its property & position sensing, device orientation, usage scenarios or operating modes and accordingly generate the trigger signal 230; (b) a processing unit for manipulation of interrupt control signal 140 according to trigger signal, antenna sensitivity, DOA and signal quality parameters; (c) An smart active radiation pattern controller 120 that works based on control signal; (d) Antenna system 110 capable of achieving dynamic radiation pattern coupled with radiation pattern controller 120 that vary and controls the radiation pattern accordingly to improve signal quality and also restores radiation according to parameters and configurations to optimise communication.
