AR-Based Roaming Test Tracking for AP Deployment Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roaming test methods for wireless access points (APs) rely on manual movement by testers, leading to potential blind spots and inaccurate evaluation of AP deployment due to lack of real-time position determination and data correlation.
Innovation Solution
Utilizing augmented reality (AR) positioning to obtain real-time AR coordinates and detection data at track points, generating a movement track, and displaying this information to enhance the evaluation of AP deployment accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual movement by testers is used to conduct roaming tests, then the test process is simple to operate, but the position determination is inaccurate and blind spots occur
Solution Approach 1:
The patent introduces an intermediary positioning system consisting of positioning beads placed at known locations in the detection region. The terminal equipment captures images of these beads to determine its own position indirectly, rather than relying on manual position reporting. This intermediary approach enables automatic, accurate position tracking without requiring complex professional testing equipment.
Solution Approach 2:
The patent creates a virtual copy of the physical detection region by establishing correspondence between the real-world detection region and a virtual detection region in the coordinate system. The movement track and detection data are visualized in this virtual copy, allowing accurate position determination and analysis without directly measuring physical positions.
2Loss of information
If manual movement and observation are used, then the equipment cost is low, but the detection data correlation with position is lost
Solution Approach 1:
The patent implements automatic feedback by continuously capturing the terminal equipment's position through image recognition of positioning beads and automatically correlating this position data with detection results. The system feeds back the movement track and position information to the tester in real-time, eliminating the need for manual position recording and ensuring accurate position-data correlation throughout the testing process.
Solution Approach 2:
The patent replaces the mechanical manual position recording system with an automated optical recognition system. Instead of testers manually observing and recording positions, the system uses the terminal equipment's camera to capture images of positioning beads, automatically processes these images to determine position, and correlates this with detection data, thereby preventing information loss.
3Measurement precision
If AR positioning is implemented, then the movement track and detection data are accurately obtained, but the system complexity increases
Solution Approach 1:
The patent uses inexpensive positioning beads as temporary markers throughout the detection region. These simple objects serve as reference points for position determination without requiring complex infrastructure. The beads are stationary and reusable, providing a cost-effective solution that avoids the need for expensive professional positioning systems while maintaining high measurement precision.
4Reliability
If real-time position and detection data are obtained, then the AP deployment evaluation is more accurate, but the data processing complexity increases
Solution Approach 1:
The patent makes the terminal equipment perform multiple functions: it serves as both the testing device for AP evaluation and the positioning device for tracking. The same device that measures network parameters also captures images for position determination, eliminating the need for separate positioning equipment and reducing overall system complexity while improving evaluation reliability through integrated data collection.
