Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication network planning methods face challenges due to limited accuracy in geographic databases, requiring substantial computing power and time, and are inefficient in reducing operating costs and resources.
Innovation Solution
The method involves identifying triplets of Primary Elements based on geometrical visibility, evaluating geometrical optics interactions, and creating a three-dimensional model of the geographic area by dividing it into parcels based on threshold distances for reflected and diffracted electromagnetic radiations, using an automatic interpretation process to filter and refine the raster database, and optimizing polygon shapes for accurate modeling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If prism-based geographic database modeling is used for Ray Tracing, then the geographic area can be represented in three dimensions, but the results are affected by anomalies due to differences between prism surfaces/corners and actual building shapes
Solution Approach 1:
The patent segments buildings into multiple planar facets instead of using simple prism models. Each building is divided into several flat surfaces that better approximate the actual building geometry, allowing Ray Tracing to more accurately represent electromagnetic wave interactions with building surfaces while maintaining computational efficiency.
Solution Approach 2:
The patent implements a dynamic database update mechanism that automatically detects and incorporates building changes (new constructions, demolitions, modifications) into the geographic database. This ensures the database remains current and accurate, improving the precision of electromagnetic field measurements without requiring complete manual redrawing of all building models.
2Quantity of substance
If aerial and satellite-based photogrammetry is used to identify buildings, then building information can be obtained, but the process requires substantial computing power and time to organize raster data into vectorial database
Solution Approach 1:
The patent implements an automated system that performs chromatic analysis of raster pixels, automatically groups them into building representations, and converts them to vectorial database format without requiring manual intervention. The system self-updates when building changes are detected, eliminating the need for labor-intensive manual database maintenance and significantly improving productivity.
Solution Approach 2:
The patent pre-processes and stores building information in an optimized format that facilitates rapid updates. When building changes are detected through automated monitoring, the system can quickly update only the affected portions of the database rather than processing the entire geographic area, thereby maintaining high productivity while handling large quantities of geographic data.
3Manufacturing precision
If detailed prism models are used for each building, then accurate building representation is achieved, but the computing time and resources required for Ray Tracing increase substantially
Solution Approach 1:
The patent segments buildings into a limited number of planar facets rather than using highly detailed continuous surface models. This segmentation approach maintains sufficient geometric accuracy for electromagnetic wave interaction calculations while dramatically reducing the computational complexity of Ray Tracing operations, thereby reducing computing time and resource requirements.
Solution Approach 2:
The patent applies a level of modeling detail that is sufficient for the specific application requirements rather than using maximum possible detail. The planar facet representation provides adequate accuracy for Ray Tracing purposes without the excessive computational burden of more detailed models, achieving the optimal balance between accuracy and computing time for radio communication network planning.
