Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks using the millimeter wave band, the strong rectilinearity of radio waves and susceptibility to obstacles make it difficult for users to determine the optimal posture and orientation of terminals to maintain communication quality, as slight changes in posture or orientation can significantly affect the communication coverage area.
Innovation Solution
A wireless communication apparatus with a display unit that indicates the radiation direction of beams formed through beamforming, allowing users to identify the optimal orientation for improved communication quality by displaying patterns representing the radiation direction and reception quality of the selected beam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beamforming is used to improve communication quality and extend cell area, then the radio wave directionality is improved and communication rate increases, but the communication coverage area becomes sensitive to terminal posture and orientation changes
Solution Approach 1:
The patent implements a display unit that provides visual feedback to users about the current beam direction and communication quality. The display shows directional information indicating the optimal orientation for maintaining high-quality communication, allowing users to adjust terminal posture based on real-time feedback without needing to understand complex technical parameters.
2Productivity
If the radiating angle range is narrowed to improve directionality, then communication rate and SINR are improved, but the communication coverage area becomes more restricted and sensitive to orientation changes
Solution Approach 1:
The patent employs dynamic beamforming that can adaptively adjust beam direction and width based on terminal movement and environmental conditions. The system continuously tracks the optimal beam direction and updates the display information accordingly, allowing the narrow beam to dynamically follow the terminal while maintaining high transmission rates and extended coverage adaptability.
