Mobile Signal Location Flagging for Emergency Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing GPS-enabled personal devices face challenges with intermittent network coverage, rendering them useless in areas with poor signal quality, especially during emergencies when access to reliable communication is critical.
Innovation Solution
A system that flags the last known good signal location and provides guidance back to it, utilizing GPS, wireless, and cellular network data, allowing users to quickly regain access to signal even in areas with poor coverage by maintaining directions to previously recorded signal strongholds, and sharing this data for improved network coverage assessment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS and network coverage are relied upon for communication and safety, then location tracking and emergency communication are enabled, but the system becomes useless in areas with poor or no network coverage
Solution Approach 1:
The system performs preliminary actions by flagging and storing the last known good signal location before network coverage is lost. This allows the device to maintain functionality and provide guidance back to signal coverage areas even when currently in areas with poor or no coverage, resolving the contradiction between reliability and adaptability.
2Reliability
If the device continuously monitors signal quality and maintains navigation capabilities, then users can quickly regain access to signal, but the device complexity and power consumption increase
Solution Approach 1:
The system extracts only the critical function needed for signal recovery by flagging the last known good location and providing basic directional guidance, rather than implementing full continuous navigation monitoring. This reduces device complexity while maintaining the essential reliability of signal access.
3Measurement precision
If detailed signal strength data is collected and shared from multiple users, then network coverage assessment is improved, but user privacy and data security concerns increase
Solution Approach 1:
The system uses anonymized copies of signal strength data rather than sharing detailed personal location information. This allows accurate network coverage assessment through aggregated data while protecting user privacy by removing personally identifiable information, resolving the contradiction between measurement precision and privacy protection.
