Mobile Transceiver Network Selection via Waypoint Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
GNSS tracking devices face challenges in efficiently operating across wireless carrier and network coverage boundaries, especially during long-range transit, due to limited power and processing resources, and varying wireless service availability.
Innovation Solution
A mobile transceiver equipped with multiple wireless transceivers (4G LTE, 3G, 2G, WLAN/Wi-Fi, and Bluetooth) that selectively activates the appropriate transceiver based on pre-programmed waypoints and available network services, extending battery life by minimizing power consumption and ensuring continuous tracking across international borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wireless transceivers are equipped for global coverage, then tracking reliability across international borders is improved, but power consumption and device complexity increase
Solution Approach 1:
The system dynamically selects which wireless transceiver to activate based on the device's current geographic location and the available network services at each waypoint. This dynamic adaptation allows the device to use only the necessary transceiver for the current region, reducing power consumption while maintaining global tracking reliability.
Solution Approach 2:
The system pre-programs multiple waypoints with associated network service information before deployment. By having this information available in advance, the device can proactively select the appropriate transceiver before needing to communicate, avoiding unnecessary power consumption from scanning or attempting to use unavailable networks.
2Adaptability or versatility
If multiple wireless transceivers are activated continuously for network selection, then network availability is improved, but battery life deteriorates
Solution Approach 1:
The system extracts and utilizes only the specific network service information relevant to the current geographic region from the pre-programmed waypoint data. By filtering and using only the necessary network information rather than continuously managing all possible networks, the system maintains network availability while significantly reducing the power consumption associated with continuous transceiver activation.
3Reliability
If network selection is performed frequently across carrier boundaries, then communication reliability is improved, but processing resource consumption increases
Solution Approach 1:
The system performs preliminary organization of network service information by geographic region during the configuration phase. By having waypoint-specific network information pre-sorted and ready, the device can quickly retrieve and use the appropriate network data when crossing carrier boundaries, avoiding the need for complex real-time network scanning and selection processes that would consume excessive processing resources.
