Adaptive Access Point Configuration for Power-Constrained Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless access points (APs) face challenges in maintaining performance and connectivity for client devices when operating in reduced-capabilities (RC) mode due to varying power levels from Power over Ethernet (PoE) ports, leading to reduced coverage and throughput.
Innovation Solution
The implementation of an adaptive configuration control (ACC) module in wireless APs that dynamically adjusts operating parameters such as transmit power, active antenna chains, and feature enablement based on real-time power availability, client device characteristics, and neighboring APs' operating states to maintain optimal performance in RC mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the AP operates in RC mode to reduce power consumption, then power consumption is reduced, but coverage and throughput are adversely affected
Solution Approach 1:
The patent implements dynamic configuration adjustment where the AP continuously monitors power availability and client device requirements, then adaptively modifies operating parameters such as transmit power levels, active antenna chains, and enabled features. This dynamic approach allows the system to optimize the balance between power consumption and performance based on real-time conditions, rather than being locked into fixed FC or RC modes.
2Use of energy by moving object
If the AP uses a predetermined RC mode configuration, then power consumption is reduced, but client device performance is adversely affected
Solution Approach 1:
The patent changes multiple operating parameters dynamically based on power availability and client requirements. These parameters include transmit power levels, the number of active antenna chains, enabled wireless features, and channel selection. By adjusting these parameters in response to real-time conditions, the system maintains client device throughput and coverage even when operating in reduced power mode, rather than using a static predetermined configuration.
3Use of energy by moving object
If the AP enters low power mode when no clients are connected, then power consumption is reduced, but the AP cannot maintain full capabilities when clients connect
Solution Approach 1:
The patent prepares the AP for rapid capability restoration by maintaining a ready state where configuration parameters can be quickly adjusted when client devices connect. Instead of entering a deep low-power state that would require lengthy initialization, the system uses preliminary action to keep essential functions active and ready, allowing immediate adaptation to client requirements while still reducing power consumption during idle periods.

AI summary
Methods, systems and devices for controlling an operating configuration of a network device such as a wireless access point include detecting power supplied to the access point. Operating parameters of the access point, neighboring access points, and client devices wirelessly connected to the access point are determined. The access point is placed in a reduced-capability operating configuration in response to detecting the power supplied is less than a power threshold. The reduced-capability operating configuration is based on the determined operating parameters of the access point, neighboring access points, and client devices.
