Engineering Contradiction Analysis
1Measurement precision
If conventional 2-D heatmaps are used to visualize Wi-Fi coverage, then the visualization process is simple, but the accuracy in predicting coverage issues and dead zones deteriorates
Solution Approach 1:
The patent transitions from conventional 2-D heatmaps to a 3-D heatmapping system that visualizes Wi-Fi wave patterns in three-dimensional space. This dimensional change enables the system to accurately represent signal propagation through multiple floors and levels, capturing the true spatial distribution of RF signals and identifying dead zones that cannot be detected in 2-D representations.
Solution Approach 2:
The system creates a virtual copy of the physical environment by receiving site survey data containing coordinates and composition characteristics of structural walls and fixtures. This virtual replica allows the system to simulate Wi-Fi wave patterns without physically deploying access points throughout the building, enabling accurate coverage prediction while reducing implementation complexity.
2Reliability
If access points are placed to provide coverage in dead zones, then network availability improves, but the difficulty in predicting optimal placement locations increases
Solution Approach 1:
The system performs preliminary simulation of Wi-Fi wave patterns in the virtual environment before actual access point deployment. By pre-calculating signal propagation through the virtual model that incorporates structural walls and fixtures, the system identifies optimal access point placement locations and predicts coverage issues in advance, eliminating the need for trial-and-error deployment.
Solution Approach 2:
The system provides feedback by displaying the simulated wave patterns and coverage heatmaps to users, allowing them to visualize predicted dead zones and optimal access point placements. This feedback mechanism enables informed decision-making about access point positioning without requiring complex manual analysis of signal propagation.
3Manufacturing precision
If 3-D heatmapping is implemented to accurately visualize wave patterns, then coverage optimization improves, but the computational resources and system complexity increase
Solution Approach 1:
The system uses a virtual copy of the physical environment created from site survey data to perform complex wave pattern simulations. This virtual replica allows the system to accurately model RF signal propagation through structural walls and fixtures without requiring complex real-time measurements or physical deployment of test equipment throughout the building.
Solution Approach 2:
The system receives and processes specific parameters from the site survey including coordinates of structural walls and fixtures, and composition characteristics of these structures. By incorporating these specific parameters into the virtual environment model, the system achieves accurate wave pattern visualization and coverage prediction without requiring overly complex measurement and computation systems.
