Mobile Device Route Communication Quality Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wireless communication devices face challenges in readily recognizing communication quality, especially when the device is in motion, such as on a train, as the area of communication changes continuously, leading to uncertainty about the quality of service at the destination.
Innovation Solution
A mobile device and method that obtain position information along a route and calculate communication quality information, displaying it to the user, including specifying the route of travel and displaying communication quality at intervals, using a combination of processors, storage units, and control units to determine the nearest location and communication quality on that route.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If communication quality information is displayed only at the current position, then the device complexity is low, but the user cannot recognize communication quality at the destination when moving
Solution Approach 1:
The system performs preliminary actions by obtaining position information along the route and calculating communication quality information for future positions before the user reaches them. The specifying unit determines the route of travel in advance, and the communication quality information obtaining unit retrieves quality data for multiple positions along this route, not just the current position. This allows users to see communication quality at their destination before they arrive there.
2Loss of information
If the system calculates communication quality for multiple positions along the route, then the user can recognize destination quality, but the loss of time increases due to continuous position tracking
Solution Approach 1:
The system segments the route into discrete position points along the travel path. Instead of continuously tracking and calculating communication quality at every moment, the specifying unit divides the route into specific positions (first position, second position, third position, etc.), and the communication quality information obtaining unit retrieves quality data for these segmented positions. This segmentation reduces the overall processing time while still providing comprehensive quality information along the route.
3Measurement precision
If the system obtains position information continuously, then the accuracy of route tracking is high, but the use of energy increases
Solution Approach 1:
The system implements periodic action by obtaining position information at specific intervals along the route rather than continuously. The specifying unit determines key positions along the travel route, and the position information obtaining unit acquires location data at these periodic points. This periodic sampling maintains sufficient measurement precision for route tracking while significantly reducing energy consumption compared to continuous position monitoring.
