Solution Overview

Problem

Existing network design methods for 5G communication systems using high frequency bands are inefficient due to the long computation times required for accurate analysis of electromagnetic wave characteristics, such as transmission, reflection, and diffraction, which affect the reliability and speed of base station installation and number determination.

Innovation Solution

The method involves splitting the analytical region into multiple sub-regions and performing simplified analysis on each, using ray tracing techniques to ensure reliability before conducting a full analysis, thereby reducing redundant computations and improving accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If full analysis is performed on the entire analytical region to ensure accuracy of electromagnetic wave characteristics, then measurement precision is improved, but loss of time increases

Engineering Contradiction:
Improveaccuracy of electromagnetic wave characteristicsVSAvoidcomputation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The analytical region is divided into multiple sub-regions, allowing the system to perform simplified analysis on individual sub-regions rather than conducting full analysis across the entire region. This segmentation enables accurate electromagnetic wave characteristic analysis to be focused only where needed, reducing overall computation time while maintaining measurement precision in critical areas.

Inventive Principle:
Principle #1Segmentation

2Productivity

If simplified analysis is performed on sub-regions to reduce computation time, then productivity is improved, but measurement precision deteriorates

Engineering Contradiction:
Improveanalysis speedVSAvoidaccuracy of analysis results
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system applies different analysis methods to different sub-regions based on their specific characteristics. Simplified analysis is performed on sub-regions where it suffices, while full analysis is conducted on sub-regions requiring higher precision. This local differentiation maintains measurement precision where necessary while improving overall productivity through selective application of analysis depth.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of performing full analysis uniformly across all regions, the system applies partial analysis (simplified method) to sub-regions where full analysis would be excessive. This approach achieves sufficient accuracy for most regions while reserving computationally intensive full analysis only for critical sub-regions, thereby improving productivity without significantly compromising overall measurement precision.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If ray tracing techniques are used to ensure reliability of analysis results, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvereliability of analysis resultsVSAvoidcomplexity of analysis process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The analysis process is segmented into simplified analysis and full analysis with ray tracing techniques. Ray tracing is applied only to specific sub-regions where reliability is critical, rather than to the entire analytical region. This selective application maintains reliability where needed while reducing overall process complexity by avoiding unnecessary ray tracing in other areas.

Inventive Principle:
Principle #1Segmentation
