Wireless Communication Pattern Sharing for Cross-System Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in detecting and mitigating interference between different wireless communication systems, particularly in agricultural settings where local 5G networks are used, leading to radio frequency interference due to asynchronous time division transmission patterns.
Innovation Solution
A wireless communication apparatus equipped with a first and second communication unit, an acquisition unit, and a notifying unit to detect and notify base stations of time division transmission patterns in neighboring systems, allowing for reassignment of communication slots to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adjustment by licensed personnel is performed to prevent interference, then interference prevention is achieved, but operational complexity and time consumption increase
Solution Approach 1:
The wireless communication apparatus automatically detects operating information messages from neighboring systems and performs self-adjustment of communication parameters without requiring manual intervention by licensed personnel, thereby eliminating the operational burden while maintaining interference prevention
Solution Approach 2:
The apparatus continuously monitors the wireless environment by detecting operating information messages from other systems, uses this feedback to identify potential interference conditions, and automatically adjusts its communication parameters in response to maintain reliable operation
2Productivity
If automatic detection of interference is implemented, then operational efficiency improves, but system complexity increases
Solution Approach 1:
The wireless communication apparatus uses its existing second wireless communication unit, which is already configured for normal communication operations, to also detect operating information messages from neighboring systems. This multi-functional use of existing hardware avoids adding complex dedicated detection equipment while achieving automatic interference detection
3Reliability
If communication parameters are dynamically updated to avoid interference, then communication reliability improves, but information processing requirements increase
Solution Approach 1:
The apparatus extracts only the essential operating information from detected messages, specifically the time division transmission/reception pattern, which is the critical parameter needed for interference avoidance. By focusing on extracting only this key information rather than processing all message data, the system maintains communication reliability while minimizing information processing requirements
