Solution Overview
Problem
Current communication devices face challenges in directing antenna beams effectively, especially when dealing with motion and location changes of communication devices, which affects signal quality and range, particularly in environments with minimal multipath or high frequency band transitions.
Innovation Solution
The method involves using a communication device to receive location and motion data, determining antenna beam parameters to steer the antenna beam electronically or manually, and adjusting these parameters based on the data to maintain signal quality and range, even in environments with minimal reflective paths, by employing beamforming techniques and sensor data from GPS, magnetometer, gyroscope, and accelerometer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If directional or beam antennas are used to focus narrower and higher gain antenna beams in specific directions, then signal quality and spectral efficiency are improved, but the system becomes more sensitive to motion and location changes of communication devices
Solution Approach 1:
The patent implements dynamic beam steering by continuously adjusting the direction of antenna beams based on real-time motion data from sensors (accelerometer, gyroscope, magnetometer, GPS) and location changes of communication devices. The system adapts beam parameters including azimuth and elevation angles to track moving devices, ensuring consistent signal quality despite device motion. This dynamic adjustment mechanism resolves the contradiction by making the beamforming system responsive to environmental changes while maintaining focused signal transmission.
2Productivity
If beamforming techniques are employed to improve spectral efficiency and data rates, then communication performance is enhanced, but the complexity of determining and adjusting antenna beam parameters increases
Solution Approach 1:
The patent replaces complex mechanical or manual beam steering mechanisms with electronic beamforming controlled by a processor. The system uses sensor data (accelerometer, gyroscope, magnetometer, GPS) to automatically determine beam parameters such as azimuth and elevation angles. The processor electronically adjusts the phase and amplitude of signals across multiple antenna elements to steer beams in the desired direction, eliminating the need for mechanical rotation or manual adjustment. This substitution reduces operational complexity while maintaining high data rates through efficient electronic control.
3Adaptability or versatility
If omnidirectional antennas are used to provide wide coverage, then adaptability to different directions is improved, but signal quality and spectral efficiency deteriorate due to lack of focused transmission
Solution Approach 1:
The patent implements a dynamic beamforming system that adapts the radiation pattern of the antenna array based on the location and motion of communication devices. Instead of fixed omnidirectional or directional patterns, the system continuously adjusts beam direction and shape to maintain focused transmission toward active devices while providing comprehensive coverage. The processor uses real-time location data to steer multiple beams simultaneously or sequentially, ensuring high signal quality to each device while maintaining adaptability across different spatial directions.
