Wireless Grouping via Intermediary Communication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in appropriately grouping multiple wireless communication apparatuses, especially when obstructions are present, leading to inefficiencies in information exchange.
Innovation Solution
An information processing apparatus that communicates with a first wireless communication apparatus via a first communication system, receives information about a second communication system, and uses this information to control the grouping of multiple wireless communication apparatuses, associating them based on signal intensity and distance data from the second communication system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile terminals are grouped using distances and signal intensity information from the first communication system, then multicast retransmission can be performed for grouped terminals, but grouping accuracy deteriorates when obstructions are present between terminals
Solution Approach 1:
The patent introduces a second communication system as an intermediary measurement channel. Terminals measure distances to each other through this alternative communication path, which is not affected by obstructions in the first communication system. This intermediary measurement provides reliable grouping information even when direct line-of-sight is blocked.
Solution Approach 2:
The patent changes the measurement parameter from direct signal intensity in the first communication system to distance information obtained through the second communication system. By switching to a different measurement approach that is insensitive to obstruction effects, the system maintains accurate grouping capability.
2Productivity
If only first communication system information is used for grouping, then the grouping process is simple, but grouping effectiveness deteriorates in obstructed environments
Solution Approach 1:
The patent makes the grouping system multi-functional by incorporating measurements from two different communication systems. The second communication system serves as an alternative measurement channel that provides universal distance information applicable regardless of obstruction conditions in the first system.
