Wireless Signal Analysis for Unknown Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to effectively identify and characterize unknown vehicles through wireless signals, especially in scenarios where vehicles lack a data connection or proper credentials, limiting the ability to locate or determine vehicle characteristics.
Innovation Solution
A method involving a wireless receiving device that listens for and processes wireless signals from unknown vehicles, generating an electronic signature based on signal characteristics and identifiers, and comparing it with vehicle information databases to determine vehicle characteristics and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless receiving devices listen for and process signals from unknown vehicles without data connection requirements, then the ability to identify and characterize unknown vehicles is improved, but the complexity of the system increases due to signal processing and database matching requirements
Solution Approach 1:
A remote facility acts as an intermediary between wireless receiving devices and vehicle information databases. The receiving devices send captured signal information to the remote facility, which then performs database queries and returns vehicle characteristics. This intermediary approach allows the receiving devices to remain relatively simple while still achieving comprehensive vehicle identification capabilities through the centralized remote facility.
Solution Approach 2:
The system enables self-service vehicle identification by capturing wireless signals that vehicles continuously transmit for multimedia functions. The vehicle's own wireless transmissions, originally intended for entertainment purposes, are repurposed to provide identification information without requiring the vehicle to actively participate in the identification process or have specialized tracking equipment.
2Loss of information
If the system processes only non-uniquely identifying vehicle information from wireless signals, then privacy concerns are reduced, but the precision of vehicle identification decreases
Solution Approach 1:
The identification process is segmented into two stages: first, non-uniquely identifying information (signal characteristics, frequencies, protocols) is captured and processed to generate a query; second, the remote facility uses this query to retrieve uniquely identifying vehicle characteristics from the database. This segmentation allows privacy-preserving signal capture while achieving precise vehicle identification through the database matching process.
3Reliability
If existing methods require vehicles to have data connection and proper credentials, then system reliability is improved, but the versatility of vehicle tracking is reduced
Solution Approach 1:
The system uses feedback from wireless signals that vehicles continuously transmit during normal operation. By monitoring these ongoing transmissions and analyzing their characteristics, the system can identify and track vehicles without requiring them to establish formal data connections or provide credentials. The continuous signal feedback enables passive identification and characterization of unknown vehicles.
Data Source
AI summary
A system and method of determining vehicle characteristics of an unknown vehicle through evaluation of wireless signals transmitted by the unknown vehicle, wherein the method includes: obtaining information from a wireless receiving device, wherein the wireless receiving device is configured to listen for wireless signals from one or more wireless transmission devices, wherein the obtained information is based at least partly on one or more wireless signals transmitted by an unknown vehicle, and wherein the one or more wireless signals only include non-uniquely identifying vehicle information; determining one or more characteristics concerning the unknown vehicle based on evaluating the obtained information in connection with vehicle information data that is stored in a vehicle information database; and storing the one or more characteristics concerning the unknown vehicle in a database.
