Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems inaccurately determine failure in wireless networks due to simplistic reliance on packet loss rates, often mistaking external interference for device or terminal failures.
Innovation Solution
A communication system with a master device and slave devices that obtain and analyze communication characteristics like RSSI and PER to determine normal or abnormal communication, identifying specific abnormal positions by correlating results across multiple frequency channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system uses multiple master communication devices and multiple slave communication devices to perform wireless communication and analyze communication characteristics, then the measurement precision of abnormal position identification is improved, but the device complexity increases
Solution Approach 1:
The system segments the communication network into multiple master communication devices and multiple slave communication devices, allowing independent measurement and analysis of communication characteristics for each device pair. This segmentation enables precise identification of abnormal positions by comparing results across multiple segments without requiring complete system redesign.
Solution Approach 2:
Each communication device in the system is designed with multi-functionality, serving both as a communication endpoint and as a measurement instrument. The devices can simultaneously perform wireless communication and collect communication characteristics (RSSI, PER), eliminating the need for separate measurement equipment and reducing overall system complexity despite multiple devices being deployed.
2Reliability
If the system records and analyzes communication characteristics from multiple device combinations to determine abnormal positions, then the reliability of failure determination is improved, but the loss of time for data collection and analysis increases
Solution Approach 1:
The system performs preliminary collection of communication characteristics (RSSI, PER) during normal operation and stores them in advance. When an abnormality is detected, the pre-collected data from multiple device combinations is immediately analyzed without requiring new measurements, significantly reducing the time needed for reliable failure determination while maintaining high reliability through multi-source data validation.
3Measurement precision
If the system uses a recorder to store combinations of devices with communication abnormalities and an abnormal position finalization unit to cross-validate results, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The recorder acts as an intermediary component that stores communication abnormality data from multiple device combinations, while the abnormal position finalization unit serves as a mediator that cross-validates results by comparing recorded data with real-time measurements. This intermediary structure enables precise abnormal position identification through systematic data comparison without requiring direct complex interactions between all device pairs.

AI summary
A communication system includes a master communication device and slave communication devices. The master communication device obtains information indicative of communication characteristics. The communication system records a combination of the master communication device and at least one of the slave communication devices having a communication abnormality. The system finalizes an abnormal position where the abnormality is occurring when an abnormality-determined position is consistent with a recorded combination of the master communication device and the at least one of the slave communication devices having a communication abnormality.
