Antenna Information Distribution for Location Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing location determination techniques in wireless communication systems often rely on assumptions about antenna attributes, such as omnidirectional patterns, which can lead to inaccurate position calculations due to incorrect assumptions about antenna types or configurations.
Innovation Solution
A method and system where a mobile device collects and shares antenna information for wireless nodes, allowing a remote device to store and provide assistance data, including antenna parameters, to improve location determination accuracy by accounting for actual antenna characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If antenna information is not collected and shared across multiple devices, then device complexity is reduced, but location determination accuracy deteriorates due to incorrect assumptions about antenna attributes
Solution Approach 1:
The patent combines antenna information from multiple wireless devices into a centralized database, merging individual device measurements to create comprehensive antenna profiles that improve location determination accuracy without requiring each device to independently maintain complex antenna information
Solution Approach 2:
The patent introduces a server as an intermediary that collects, stores, and distributes antenna information between wireless devices and location determination systems, eliminating the need for direct peer-to-peer information exchange and reducing overall system complexity
2Measurement precision
If antenna information is collected from multiple wireless devices, then location determination accuracy is improved, but information management complexity increases
Solution Approach 1:
The patent creates a universal antenna information database that serves multiple functions: storing antenna profiles, providing assistance data for location determination, and enabling accurate position calculations across different wireless devices and scenarios, consolidating what would otherwise be multiple separate information management systems
Solution Approach 2:
The system enables wireless devices to automatically retrieve antenna information from the database without requiring manual configuration or complex information exchange protocols, allowing devices to self-configure for accurate location determination
