Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnosing and improving wireless local area network (WLAN) performance is challenging due to unpredictable interactions with physical environments and limited remote troubleshooting capabilities, making it difficult for service providers to identify and resolve user issues effectively.
Innovation Solution
A wireless access point (WAP) profiler device that collects performance metrics, generates a numerical score or profile to characterize WLAN performance, and provides recommendations for improvement, allowing for both reactive troubleshooting during support sessions and proactive monitoring to detect trends and optimize network quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional remote troubleshooting methods are used, then service providers can attempt to diagnose issues remotely, but the ability to effectively identify and resolve user issues is limited due to lack of detailed WLAN performance data
Solution Approach 1:
The system performs preliminary profiling of WLAN access points by collecting performance metrics, signal strength data, and environmental information before troubleshooting is needed. This advance characterization enables service providers to quickly diagnose issues without requiring extensive remote investigation, as the baseline performance data is already captured and stored for comparison.
Solution Approach 2:
A profiler device acts as an intermediary between the WLAN infrastructure and service providers. This intermediary automatically collects detailed performance metrics, signal characteristics, and environmental data from multiple access points, transforming raw network data into actionable intelligence that service providers can use for effective remote troubleshooting without needing direct physical access to the network.
2Ease of operation
If multiple wireless networks are deployed across many areas to provide convenient access, then mobile clients gain better connectivity, but the effort for configuring and reconfiguring access points and client devices increases significantly
Solution Approach 1:
The profiling system enables self-service capabilities by automatically generating performance profiles and diagnostic information without requiring manual configuration of access points or client devices. The system autonomously collects metrics, analyzes performance issues, and provides actionable insights, eliminating the need for technical staff to manually reconfigure networks when clients move between areas.
Solution Approach 2:
The system dynamically adjusts and monitors multiple WLAN parameters including signal strength thresholds, channel selections, and access point power levels based on collected performance data. By automatically optimizing these parameters rather than requiring manual reconfiguration, the system maintains convenient client connectivity across multiple areas while minimizing configuration time and effort.
3Measurement precision
If detailed WLAN performance analysis is performed to diagnose issues accurately, then troubleshooting precision improves, but the complexity of collecting and analyzing multiple performance metrics increases
Solution Approach 1:
The profiling system divides WLAN performance analysis into distinct modular components: signal strength measurement, quality of service monitoring, environmental factor tracking, and diagnostic report generation. Each component independently collects and processes specific metrics, then integrates results to provide comprehensive diagnostics. This segmentation reduces overall system complexity while maintaining high diagnostic precision through specialized measurement modules.

AI summary
A method for profiling the performance of a wireless local area network may include receiving, from a wireless access point (WAP), measurements associated with client devices in a wireless local area network (WLAN), and identifying a dominance of the client devices in the WLAN. The method may further include classifying the received measurements into categories representing channel qualities with the client devices in the WLAN, and transforming the categories of the client devices into values. The method may further include determining a profile of the WLAN based on the values and the dominance of the client devices.
