Electronic Device Location Measurement Using Dynamic Method Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Location measurement methods using GNSS, Wi-Fi, and cell ID often provide inaccurate results in urban areas due to multi-path effects and unreliable AP-related information, degrading service quality.
Innovation Solution
An electronic device that identifies its location using a communication module, determines a block in a location measurement map based on priority information and position source information, and selects the most accurate location measurement method to provide precise location information, utilizing a processor to activate appropriate antennas for GNSS, Wi-Fi, or cell ID positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GNSS location measurement method is used, then location accuracy is improved in open fields, but location accuracy deteriorates in urban areas with multi-path effects
Solution Approach 1:
The system dynamically changes the location measurement method based on environmental parameters. When multi-path interference is detected in urban areas, the system switches from GNSS to alternative methods such as Wi-Fi or cell ID-based positioning, thereby adapting to changing conditions and maintaining location accuracy despite harmful environmental factors
Solution Approach 2:
The system introduces an intermediary decision-making layer that selects between multiple location measurement methods based on current environmental conditions. This mediator evaluates the suitability of GNSS versus other methods and chooses the most appropriate one, preventing direct exposure to multi-path interference effects
2Ease of operation
If Wi-Fi location measurement method is used, then location information can be obtained in urban areas, but accuracy deteriorates when AP-related location information is potentially inaccurate
Solution Approach 1:
The system implements feedback mechanisms to evaluate the quality and reliability of location information from different sources. When Wi-Fi based location information is determined to be potentially inaccurate, the system receives feedback about this inaccuracy and switches to alternative location measurement methods, thereby maintaining accuracy while preserving the ability to obtain location information in urban areas
3Adaptability or versatility
If multiple location measurement methods are maintained, then adaptability to different environments is improved, but device complexity increases
Solution Approach 1:
The system employs dynamic selection of location measurement methods rather than maintaining all methods simultaneously in an active state. The system transitions between different location measurement approaches based on environmental conditions, achieving environmental adaptability while reducing the operational complexity by activating only the most suitable method at any given time
