Antenna Selection Circuit for Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems using MU-MIMO technology face inefficiencies in antenna utilization, leading to suboptimal transmission power and shorter transmission distances due to the need for beamforming to compensate for weaker signal strengths across multiple antennas.
Innovation Solution
A control circuit connected to multiple antennas compares signal strength indicators to select the optimal antennas for transmission and reception, allowing for efficient antenna utilization without beamforming, thereby enhancing transmission power and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming technology is used to compensate for weaker signal strengths across multiple antennas, then signal strength is improved, but device complexity and transmission distance are worsened
Solution Approach 1:
The patent extracts and removes the beamforming technology from the system, selecting only the antenna with the strongest signal strength for transmission and reception. This eliminates the complexity of beamforming while maintaining reliable communication through optimal antenna selection based on signal strength comparison.
2Reliability
If beamforming technology is used to compensate for weaker signal strengths across multiple antennas, then signal strength is improved, but transmission distance is worsened
Solution Approach 1:
By removing beamforming and instead selecting the antenna with maximum signal strength, the system achieves longer transmission distance. The strongest antenna provides sufficient signal strength without the limitations imposed by beamforming complexity, enabling extended communication range.
3Reliability
If multiple antennas are used for transmission and reception, then service quality is improved, but antenna utilization efficiency is worsened
Solution Approach 1:
The patent extracts the essence of multi-antenna usage by selecting only the single best antenna based on signal strength comparison. This eliminates the inefficiency of using multiple antennas simultaneously while maintaining service quality through optimal antenna selection, thereby improving overall antenna utilization efficiency.
4Reliability
If beamforming is used to maintain transmission performance, then signal coverage is improved, but transmission power is worsened
Solution Approach 1:
By removing beamforming and selecting the antenna with the strongest signal strength, the system achieves better signal coverage with lower transmission power. The strongest antenna naturally provides better coverage without requiring the additional power that would be needed if beamforming were used to compensate for weaker antenna performance.
