Wireless Beamforming via Server-Managed Optimized Beam Tables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices using beamforming technology face challenges in maintaining consistent communication quality due to differences in gain between peak and valley beam directions, leading to varying data rates and interference, which can be costly to address through hardware upgrades.
Innovation Solution
A wireless communication system that utilizes a server to select and provide optimized beam tables to devices, reducing the need for costly hardware upgrades by storing and managing multiple beam patterns, including those with null points for interference reduction, and using geographic data to improve beam alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If uniform angular interval beam patterns are used, then device complexity is reduced, but communication quality varies between peak and valley directions
Solution Approach 1:
The patent applies local quality by creating non-uniform beam patterns where the angular interval between beams is adjusted based on specific directional requirements. Beam intervals are made smaller in directions with interference sources or users requiring better coverage, while maintaining larger intervals in other directions. This localized optimization improves communication quality in critical directions without uniformly increasing device complexity across all directions.
2Object-affected harmful factors
If optimized beam patterns with null points are implemented, then interference is reduced, but hardware cost increases significantly
Solution Approach 1:
The patent implements parameter changes by modifying the beam pattern parameters (angular intervals, beam directions, and null point positions) through software configuration rather than hardware modification. The system adjusts these parameters dynamically based on the environment, allowing null points to be positioned toward interference sources without requiring additional hardware components. This approach reduces interference while avoiding significant hardware cost increases.
3Device complexity
If beamforming is performed with fixed beam patterns, then device complexity is minimized, but data rate varies due to gain differences
Solution Approach 1:
The patent applies dynamics by making the beam pattern parameters adaptive rather than fixed. The system dynamically adjusts beam directions, angular intervals, and null point positions based on real-time environmental conditions, user positions, and interference sources. This dynamic adjustment ensures that optimal beam patterns are used for different communication scenarios, maintaining high data rates without requiring overly complex fixed hardware configurations.
