Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile HetNet environments, existing technologies face challenges in accurately determining the geo-location of devices, especially indoors where GPS signals are unavailable, and in scenarios requiring precise location data for emergency services or regulatory compliance.
Innovation Solution
A method and system for triangulating the location of wireless access points and user devices using signal strengths and coordinates, allowing for the calculation of device distances and subsequent determination of geo-location coordinates, which are then stored for use in location-based services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS is used for geo-location, then location accuracy is improved, but device compatibility is limited and indoor availability is poor
Solution Approach 1:
The patent introduces wireless access points as intermediary nodes to enable location determination. Instead of relying solely on GPS satellites, the system uses access points as mediators that can be detected by mobile devices to calculate location through triangulation, thereby improving indoor availability and device compatibility while maintaining location accuracy
Solution Approach 2:
The patent substitutes the mechanical/GPS-based location system with a wireless network-based location system. By replacing GPS satellite signals with wireless access point signals, the system achieves better indoor performance and broader device compatibility while maintaining measurement precision through signal strength-based distance calculation
2Adaptability or versatility
If wireless access points are used for triangulation, then indoor location capability is improved, but measurement precision may be affected by signal strength variability
Solution Approach 1:
The patent employs partial action by using signal strength measurements that are not perfectly accurate but are sufficient for location determination. By accepting approximate distance values derived from signal strengths and using them in triangulation calculations, the system achieves indoor location capability while maintaining acceptable precision for most applications
Solution Approach 2:
The system incorporates feedback mechanisms where location data from multiple access points is continuously collected and processed. The triangulation algorithm refines location estimates by considering multiple signal strength measurements, thereby improving measurement precision while maintaining indoor location capability
