GPS-Based Server Routing for Field Data Uploads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
First responders and in-the-field operations face challenges in quickly and securely uploading large video data files from wireless field devices to centralized servers due to bandwidth limitations and the need to maintain a chain of custody, especially when multiple video servers with different IP addresses are involved.
Innovation Solution
A system and method that uses GPS location information to determine the nearest data storage server and route data file uploads through wireless access points, prioritizing local servers for faster uploads while ensuring chain of custody, utilizing wireless field devices with GPS modules and data recording systems to manage data transfers efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is uploaded over cellular or satellite networks, then data can be transmitted wirelessly from field devices, but upload speed is slow and cost is prohibitive
Solution Approach 1:
The patent introduces wireless access points as intermediary devices that establish local Wi-Fi networks at enterprise locations. Field vehicles connect to these local access points instead of using cellular networks, creating an intermediate transmission layer that enables high-speed data transfer while maintaining wireless operation. The access point mediates between the field device and the enterprise network infrastructure.
2Reliability
If data is uploaded to centralized servers located at enterprise facilities, then data security and chain of custody are maintained, but upload time increases due to vehicle travel time to these locations
Solution Approach 1:
The patent implements multiple local data storage servers distributed at different enterprise locations (police stations, jails, fire stations, etc.) rather than relying on a single centralized server. Each server serves its local geographic area, allowing field vehicles to upload data to the nearest available server. This localizes the data storage function, reducing travel time while maintaining security through distributed server architecture and chain of custody protocols.
3Productivity
If multiple data storage servers are used at different enterprise locations, then upload speed improves by selecting nearest server, but system complexity increases due to multiple IP addresses and routing requirements
Solution Approach 1:
The patent implements automatic server selection functionality in the field vehicle's data recording system that autonomously determines the optimal server based on GPS location and network availability. The system automatically queries available wireless access points, receives server IP address information, and routes data uploads without requiring manual configuration or user intervention. This self-service approach handles the complexity of multiple servers and IP addresses internally while presenting a simple interface to the user.
4Quantity of substance
If large video data files are retained on vehicle storage until upload is possible, then upload bandwidth requirements are reduced, but vehicle downtime increases while waiting for upload opportunities
Solution Approach 1:
The patent enables continuous data upload operations by establishing wireless connections to local access points whenever the vehicle is within range of enterprise locations. Rather than waiting for scheduled upload times or specific conditions, the system continuously monitors for available networks and uploads data as soon as connectivity is established. This eliminates idle time and keeps the data transmission process continuously active whenever opportunities arise.
