Fixed Radio Device Location via Mobile Proxy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed-location radio devices face challenges in obtaining accurate and reliable geographic location information due to the infrequency of movement and deployment in environments with poor GPS triangulation, making it uneconomical to integrate self-determining location capabilities and leading to inaccurate location data reporting.
Innovation Solution
A method where a separate electronic device with location-determining capabilities is brought into close proximity to the fixed-location radio device to obtain and verify location data, which serves as a proxy for the radio device's location, using techniques such as short-range communication links, time stamps, and spectrum fingerprint verification to ensure accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS receiver or self-determining location capability is integrated into the fixed-location radio device, then location determination accuracy is improved, but device cost increases
Solution Approach 1:
A mobile device acts as an intermediary to transfer location information to the fixed-location radio device. The mobile device determines its own location using GPS or other location services, then communicates this location data to the fixed radio device via short-range communication (NFC, Bluetooth, Wi-Fi), eliminating the need for the fixed device to have its own location determination hardware
Solution Approach 2:
The invention makes location determination capability universally available to fixed radio devices through any mobile device that can perform location services. Instead of each fixed device needing its own GPS receiver, any mobile device can serve as a location source, making the location determination function universal and accessible without additional hardware cost
2Loss of information
If GPS triangulation is used for location determination, then location data can be obtained, but accuracy deteriorates in indoor or poor signal environments
Solution Approach 1:
The mobile device serves as an intermediary that can obtain location information through multiple methods (GPS, cellular triangulation, Wi-Fi positioning, or user input) and transfer it to the fixed radio device. This intermediary approach allows the system to use the most accurate available method for each specific situation, including manual user input when automated methods fail in indoor environments
Solution Approach 2:
The system changes the parameter of location determination method based on environmental conditions. Instead of relying solely on GPS triangulation, the mobile device can switch between different location determination methods (GPS, cellular, Wi-Fi, manual input) depending on signal availability and environment, thereby maintaining accuracy across diverse conditions
3Adaptability or versatility
If location data is reported in different formats and reference point datums, then device compatibility is improved, but system complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the mobile device and fixed radio device communicate to determine the optimal location data format and datum. The system can detect what format the fixed device expects and automatically convert or report location data in the appropriate format, eliminating the need for manual configuration of multiple datums and formats across different devices
Data Source
AI summary
To determine precise geographical location of a fixed-location radio device, the fixed-location radio device may enter a configuration mode and receive location data from a separate electronic device that is within close proximity to the fixed-location radio device. The location of the electronic device is used as a proxy for the location of the fixed-location radio device.
