Texting Location Database for Cellular Coverage Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In areas with limited cellular network coverage, individuals, especially adventurers, face challenges in locating nearest service areas to seek assistance during emergencies, as their cell phones become unreliable for communication.
Innovation Solution
A smartphone app, Adventure Rescue Locator (ARL), and its companion Buddy app facilitate communication of location and other information via SMS, building a database of 'good' locations for text messaging and phone calls, allowing users to check-in and alert contacts or emergency services, even in low signal areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If cellular networks expand coverage to more areas, then network coverage area increases, but the reliability of communication in previously uncovered areas deteriorates due to signal interference and quality degradation
Solution Approach 1:
The system performs preliminary actions by pre-mapping and pre-testing network coverage areas before adventurers enter them. The mobile device stores previously determined texting locations and network coverage information in advance, allowing users to know beforehand where reliable communication exists and plan their routes accordingly, rather than reacting to coverage issues during the adventure.
Solution Approach 2:
The system implements feedback mechanisms where users can report actual texting success or failure at specific locations, and the system uses this feedback to update and refine the network coverage database. This continuous feedback loop allows the system to adapt to changing network conditions and provide more accurate coverage information over time.
2Ease of operation
If users rely on cell phones for communication in remote areas, then communication convenience improves, but safety deteriorates when cell service is unavailable during emergencies
Solution Approach 1:
The system performs preliminary safety preparation by providing users with advance knowledge of network coverage areas and texting locations before their adventure. Users receive information about where reliable communication exists and can plan accordingly, reducing the element of surprise when service is unavailable and enabling better emergency response planning.
Solution Approach 2:
The system introduces an intermediary layer of information and planning tools between the user's mobile device and the cellular network. By providing detailed coverage maps, texting location databases, and communication status information, the system acts as a mediator that helps users understand network limitations and plan alternative communication strategies before emergencies occur.
3Ease of manufacture
If the system provides detailed network coverage information, then trip planning quality improves, but the complexity of the system increases
Solution Approach 1:
The system creates simplified copies and representations of complex network coverage data in user-friendly formats. Instead of presenting raw network infrastructure information, the system generates simplified coverage maps, texting location databases, and communication status indicators that are easy for users to interpret and use for trip planning without requiring technical expertise.
Solution Approach 2:
The system segments complex network coverage information into manageable components including separate databases for texting locations, coverage maps for different network providers, and individual user communication status tracking. This segmentation allows the system to handle complex data while presenting it in organized, digestible portions that improve trip planning without overwhelming the user.
Data Source
AI summary
A system utilizing an Adventure Rescue Locator app and a Buddy app allows an adventurer to communicate his or her location throughout an adventure. The ARL app can provide quick and simple check-in messages that transmit location and other information and build a database of known “good” locations from which an adventurer is able to communicate via text, as well as known “not good” locations. The apps can share such information with a wide user-base, thus making the location information available to others. The app can serve to display the adventurer's check-in locations on a map; alert that the adventurer has an adventure in progress; keep track of the time the adventurer is planning on returning home and alert if the Adventurer fails to arrive; auto-confirm check-in texts with the ARL app; etc.
