Mobile Body Wireless Communication Quality Map
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous mobile devices can only assess communication quality at positions they have traveled to, making it impossible to control communication quality in surrounding areas.
Innovation Solution
A mobile body equipped with a wireless communication unit and a processor that receives communication quality messages from other mobile bodies, determines a destination based on this information, and presents the destination to a user, or creates a communication quality map to search for a route with optimal communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an autonomous mobile device creates a communication quality map by traveling to various positions, then communication quality at traveled positions can be grasped, but communication quality at surrounding positions cannot be assessed
Solution Approach 1:
Other mobile bodies perform communication quality measurements and share results in advance, so the target mobile body can obtain surrounding communication quality information without physically traveling to those positions. This preliminary action by other devices eliminates the need for the target device to explore every location itself.
Solution Approach 2:
A communication quality map serves as an intermediary that aggregates and stores communication quality data from multiple mobile bodies. This map allows the target mobile body to access surrounding communication quality information without direct measurement, acting as a mediator between the devices and the information.
2Measurement precision
If a mobile body relies only on its own traveled positions for communication quality data, then data accuracy at those positions is high, but the coverage area is limited
Solution Approach 1:
The patent merges communication quality data from multiple mobile bodies into a single comprehensive communication quality map. By combining measurements from various devices that have traveled to different positions, the system achieves both high data accuracy (from actual measurements) and wide coverage area (from aggregated data sources).
