WLAN Client Experience Feedback for Adaptive Network Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network management systems, such as IEEE 802.11 networks, fail to capture the full dimension of a wireless client's experience, leading to suboptimal settings that do not align with the client's expectations or desires.
Innovation Solution
Wireless clients generate and report a Client Experience Score based on operational metrics, allowing the network infrastructure to adjust settings to improve the client's experience through AI/ML-driven optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If access points use available measures to optimize settings, then network control capability is improved, but the client experience dimension captured is insufficient
Solution Approach 1:
The patent implements a feedback mechanism where wireless clients actively report their experience metrics (throughput, latency, packet loss, signal strength) back to the network controller. This closed-loop feedback enables the network to adjust settings based on actual client experience rather than relying solely on network-side measurements, thus resolving the information loss contradiction.
Solution Approach 2:
The patent introduces an intermediary component (client experience reporting mechanism) that bridges the gap between network infrastructure and client experience. This intermediary collects detailed experience data from clients and transmits it to the controller, enabling optimized settings that truly reflect client needs while maintaining automated network control.
2Productivity
If access points optimize settings based on available measures, then network management efficiency is improved, but client satisfaction may not be maximized
Solution Approach 1:
The patent enables wireless clients to self-report their experience metrics without requiring complex network-side monitoring for each client. Clients autonomously measure and report their own throughput, latency, and signal quality, allowing the network to efficiently manage multiple clients while reliably capturing actual experience quality through direct client feedback.
3Adaptability or versatility
If more control knobs are adjusted to improve client experience, then experience optimization is improved, but system complexity increases
Solution Approach 1:
The patent focuses on optimizing key network parameters (transmit power, channel selection, modulation schemes) based on client-reported experience metrics. By systematically adjusting these critical parameters in response to client feedback, the network achieves high adaptability to client needs without requiring complex control mechanisms, thus managing system complexity effectively.

AI summary
A method for managing and controlling a wireless network includes detecting, by a wireless client, at least one operational metric associated with operations of the wireless client in a wireless local area network (WLAN) infrastructure, wherein the at least one operational metric is determined by the wireless client in response to wireless service supplied by the WLAN infrastructure, generating a client experience score based on the at least one operational metric, and transmitting the client experience score to a controller, which is configured to adjust, in response to the client experience score, at least one operational parameter of the WLAN infrastructure to cause a change to the at least one operational metric and to a subsequently generated client experience score.
