WLAN Structural Correlation Manager for Signal Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless local area networks (WLANs) face challenges in maximizing wireless communications within a subscriber's structure while minimizing interference with neighboring networks and preventing content piracy, as they often use a single channel and contention-based methods like CSMA, which can lead to overlapping signal coverage and unauthorized access.
Innovation Solution
A method and apparatus that utilize a structural correlation manager to identify the architectural structure surrounding the WLAN and correlate communication parameters to maximize wireless communications within the structure and minimize them outside, employing techniques such as beamforming and database lookups to determine and adjust signal coverage based on the subscriber's structure, thereby preventing piracy and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single channel and contention-based methods (CSMA) are used for wireless communication, then device complexity is reduced and ease of operation is improved, but signal coverage overlaps with neighboring networks causing interference and unauthorized access
Solution Approach 1:
The patent applies local quality by customizing wireless signal coverage to match the specific geometric boundaries of each subscriber's structure. The system determines structure geometry through database lookups or aerial imagery, then configures transmission parameters (beamforming weights, power levels, directional patterns) to concentrate signal energy within the subscriber's property lines while creating nulls or reduced coverage at neighboring property boundaries. This localized optimization resolves the contradiction by maintaining simple CSMA operation internally while preventing external interference through spatially-selective transmission.
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting communication parameters (transmission power, beamforming angles, frequency allocation) based on the determined structure geometry and neighboring network locations. The system modifies these parameters to maximize coverage within the subscriber's structure while minimizing leakage to adjacent properties, thereby resolving the interference problem without requiring complex alternative access methods.
2Productivity
If wireless signal coverage is extended to maximize service area, then productivity is improved, but unauthorized access and content piracy increase
Solution Approach 1:
The patent applies local quality by creating spatially-selective signal coverage that provides strong wireless service exclusively within the subscriber's structure boundaries while creating signal attenuation or dead zones at property lines. This ensures high productivity (wireless service availability) for authorized devices inside the structure while preventing unauthorized access and content piracy from neighboring properties by making the signal unusable outside the designated area.
3Reliability
If beamforming and structure-based correlation are implemented, then signal coverage is optimized within structure, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-determining the geometric boundaries of the subscriber's structure through database lookups or aerial imagery analysis before configuring the wireless transmission parameters. This advance preparation allows the system to load pre-computed beamforming weights and power allocation schemes that automatically achieve optimal coverage within the structure, reducing runtime computational complexity while maintaining high reliability through structure-based optimization.
