Wireless Client Location-Based Network Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless clients face inefficiencies and battery depletion due to the time-consuming and energy-intensive process of network monitoring and acquisition, especially when roaming, as they need to constantly scan for available access points, which is exacerbated by unpredictable service provider coverage.
Innovation Solution
A wireless client determines its location and uses stored network information in an event memory to quickly and efficiently connect to associated networks, reducing the need for a full scan by employing a limited scan mode that uses location-specific network identifiers and connection attributes to establish connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless clients perform full network scans to acquire access point information, then network acquisition reliability is improved, but battery consumption increases and connection speed decreases
Solution Approach 1:
The system performs preliminary actions by storing access point information (SSID, BSSID, channel, location) in advance during roaming events. When a connection is needed, the client retrieves pre-stored information from event memory rather than performing a full scan, significantly reducing battery consumption while maintaining reliable network acquisition.
Solution Approach 2:
The system applies local quality by creating location-specific network information caches. Instead of uniform full scans everywhere, the client stores and retrieves access point details localized to specific geographic locations (determined by GPS coordinates), enabling efficient targeted connections without exhaustive scanning.
2Adaptability or versatility
If wireless clients perform full network scans to ensure comprehensive access point discovery, then network coverage completeness is improved, but connection time increases
Solution Approach 1:
The system performs preliminary network discovery and stores access point information (SSID, BSSID, channel, location) in advance during roaming events. When a connection is needed, the client retrieves pre-stored information from event memory rather than performing a full scan, significantly reducing connection time while maintaining comprehensive network coverage through the stored cache.
Solution Approach 2:
The system creates copies of access point information (network identifiers, connection attributes, location data) and stores them in event memory. These copies enable rapid retrieval and reconnection without requiring the client to re-scan or re-discover the networks, thus reducing connection time while preserving complete network coverage knowledge.
3Loss of information
If wireless clients continuously monitor network signals to maintain connection awareness, then network visibility is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by using event-driven monitoring that activates during specific roaming events rather than continuous monitoring. The client monitors network signals periodically when location changes or roaming events occur, storing results in event memory, thereby maintaining necessary network visibility while dramatically reducing energy consumption compared to continuous monitoring.
