Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information handling systems face signal quality degradation due to the short wavelengths of mm-wave frequencies and obstacles when communicating with 5G access points, especially in enhanced reality environments that require high throughput, such as augmented and virtual reality systems.
Innovation Solution
The system employs a light sensing directionality method using positional sensors and light sensors to determine the angle of a mm-wave antenna array, conducting beamsweeping and selecting a beamsteering pattern for optimal signal quality, enabling mm-wave communication with 5G access points by adjusting the antenna radiation patterns based on initial seed data from light sources or constellation points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mm-wave frequencies are used for high throughput communication, then data transmission speed is improved, but signal quality deteriorates due to short wavelengths and obstacles
Solution Approach 1:
The system performs light sensing directionality acquisition before mm-wave beamsteering to pre-determine the angular position of the access point. This preliminary action using light sensors provides an initial direction estimate that guides the subsequent mm-wave beamforming process, enabling faster convergence to the optimal beam direction and improving connection reliability before data transmission begins
Solution Approach 2:
The patent introduces light sensors as an intermediary system to bridge the gap between the information handling system and the mm-wave access point. The light sensors detect light from LED sources to determine angular position, serving as a mediator that provides directional information without being affected by mm-wave propagation issues such as short wavelength and obstacle blocking
2Reliability
If beamsteering is used to overcome signal degradation, then communication reliability is improved, but system complexity increases due to antenna array control
Solution Approach 1:
The system performs light sensing directionality acquisition before mm-wave beamsteering to pre-determine the angular position of the access point. This preliminary action using light sensors provides an initial direction estimate that guides the subsequent mm-wave beamforming process, enabling faster convergence to the optimal beam direction and improving connection reliability before data transmission begins
Solution Approach 2:
The patent replaces complex mechanical or trial-and-error beamsteering mechanisms with an optical sensing system. Instead of using complex antenna array control algorithms or mechanical adjustments to find the optimal beam direction, the system uses light sensors to optically determine the angular position, substituting a simpler optical measurement system for the complex electromagnetic beam control problem
3Measurement precision
If light sensing directionality is used to determine antenna angle, then beamsteering accuracy is improved, but initial connection time increases due to scanning process
Solution Approach 1:
The system performs a limited angular scan using light sensors to determine the access point direction, rather than performing a complete 360-degree sweep. The scan covers only the relevant angular range where the access point is expected to be located, achieving sufficient precision for beamsteering while minimizing the time required for the initial connection process
