1Reliability

If communication means switching is performed after communication state deterioration is detected, then communication reliability is improved, but communication delay increases and temporary deterioration occurs

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidcommunication delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by predicting interference source positions and characteristics before actual interference occurs. The interference source prediction unit forecasts future interference based on current positional information, and the communication means switching unit proactively switches communication paths before deterioration happens, rather than reacting after detection. This eliminates temporary communication deterioration and reduces switching delays.
