Wi-Fi Extender Onboarding via Dynamic Power Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for onboarding a new Wi-Fi extender to a wireless network face challenges due to restricted transmission power levels based on regional deployment, which can prevent successful onboarding at desired distances.
Innovation Solution
A client device communicates with a gateway device and existing extenders to restrict network operations, allowing the new extender to onboard by switching to channels with higher transmission power, thereby extending the onboarding distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connected wireless access point device operates in restricted mode with lower transmission power to comply with regional regulations, then regulatory compliance is improved, but the onboarding distance and signal coverage are reduced
Solution Approach 1:
The system performs preliminary actions by having the connected access point transmit beacons at higher power levels before the new extender joins the network. This preliminary high-power transmission enables the new extender to detect the beacon at greater distances and successfully initiate the onboarding process, after which the system transitions to compliant restricted power levels.
Solution Approach 2:
The access point dynamically adjusts its transmission power based on the operational phase: operating in an extended mode during the onboarding phase to maximize detection range, then transitioning to a restricted compliant mode after the new extender successfully joins the network. This dynamic power adjustment resolves the contradiction between compliance and onboarding effectiveness.
2Reliability
If the connected wireless access point device transmits beacons on multiple channels to increase detection probability, then onboarding reliability is improved, but channel interference and network complexity increase
Solution Approach 1:
The system applies local quality by concentrating beacon transmissions on a single primary channel rather than distributing them across multiple channels. This focused approach simplifies channel management while maintaining high onboarding reliability, as the new extender only needs to monitor one primary channel to detect beacons and initiate connection.
3Length of moving object
If the new extender transmits probe requests at higher power levels, then the detection range and onboarding distance are improved, but energy consumption and potential interference increase
Solution Approach 1:
The system applies preliminary anti-action by having the connected access point transmit high-power beacons first to enable the new extender to detect the network at a distance. This eliminates the need for the new extender to transmit high-power probe requests, as it can passively receive the beacon and initiate association, thereby reducing its energy consumption while maintaining extended detection range.
