Access Point Power Save With Pre-Switch Connectivity Recommendations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Access points entering power save mode can cause sudden loss of connectivity or reduced performance for associated devices, leading to significant disruptions in wireless communication.
Innovation Solution
Access points generate and transmit a connectivity recommendation to associated stations before entering power save mode, indicating alternative connection points and power save details, allowing stations to prepare for uninterrupted service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If access points enter power save mode to reduce power consumption, then energy efficiency is improved, but wireless connectivity reliability deteriorates due to sudden loss of connection
Solution Approach 1:
The access point sends a connectivity recommendation message to associated stations before entering power save mode, providing advance notice of alternative connection points. This preliminary action allows stations to proactively switch connections before the power save transition occurs, maintaining service continuity without requiring the access point to remain fully operational.
Solution Approach 2:
The connectivity recommendation message acts as an intermediary mechanism that bridges the gap between power save operations and connectivity maintenance. By providing information about alternative access points through this message, the system enables smooth transition without direct interruption to wireless service.
2Use of energy by stationary object
If access points shut down or reduce power on links to save energy, then power consumption is reduced, but service continuity deteriorates causing disruptions in wireless communication
Solution Approach 1:
The system performs preliminary notification by sending connectivity recommendation messages before the access point shuts down or reduces power. This advance notice enables stations to initiate connection transitions in advance, ensuring service continuity is maintained throughout the power save operation rather than experiencing interruptions.
Solution Approach 2:
The access point enables stations to self-manage their connectivity by providing them with alternative connection information. Stations autonomously decide when and how to switch to recommended access points based on their own needs, eliminating the need for forced disconnections or service interruptions.
3Use of energy by moving object
If access points enter power save mode to optimize energy efficiency, then energy consumption is reduced, but connection stability deteriorates leading to sudden loss of connectivity
Solution Approach 1:
By sending connectivity recommendations before entering power save mode, the system stabilizes connections proactively rather than reactively. Stations receive advance notice and can smoothly transition to alternative access points, preventing sudden connection losses that would otherwise occur during the power save transition.
Solution Approach 2:
The connectivity recommendation message provides feedback to stations about available alternative access points and their characteristics. This information feedback enables stations to make informed decisions about connection transitions, maintaining stable connectivity by selecting appropriate alternative access points based on signal quality, load conditions, and other factors.
