Solution Overview
Problem
Current wireless communication systems lack standardized formats for reporting three-dimensional positioning data, leading to inaccuracies, especially in areas with varying altitudes, as existing methods assume Gaussian probability distributions that may not be suitable for all scenarios.
Innovation Solution
Transforming three-dimensional positioning data into a representation of an elliptic cylinder centered around a center point with an elliptic base in a base plane, allowing for more accurate reporting of positioning data across wireless communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If three-dimensional positioning data is reported using existing standardized formats, then compatibility with current systems is maintained, but positioning accuracy deteriorates in areas with varying altitudes
Solution Approach 1:
The patent transforms the positioning data representation by changing the geometric parameters from a two-dimensional polygon format to a three-dimensional format incorporating altitude information. This parameter change enables accurate representation of positions in areas with varying heights while maintaining compatibility through standardized reporting interfaces.
Solution Approach 2:
The invention adds a vertical dimension (altitude) to the traditional two-dimensional positioning polygon, creating a three-dimensional positioning representation. This dimensionality change allows the system to accurately capture and report positions in terrain with significant elevation variations, directly addressing the accuracy problem in mountainous or urban areas.
2Measurement precision
If three-dimensional polygon data is reported using non-standardized formats, then positioning accuracy improves, but standard compatibility deteriorates
Solution Approach 1:
The patent creates a universal reporting format that can handle both two-dimensional and three-dimensional positioning data through a single standardized interface. The transformation device converts various input formats into a unified three-dimensional polygon representation that can be reported using existing standardized protocols, ensuring broad compatibility while maintaining accuracy.
3Ease of operation
If a two-dimensional polygon format is used to report three-dimensional positioning data, then ease of reporting is maintained, but positioning accuracy deteriorates in varying altitude areas
Solution Approach 1:
The invention extends the two-dimensional polygon format by incorporating altitude information to create a three-dimensional representation. This allows the system to maintain the simplicity and ease of polygon-based reporting while accurately capturing vertical position variations, thus improving accuracy without sacrificing operational ease.
