Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
G3-PLC mesh communication networks are limited by the inability to dynamically switch between frequency bands, leading to potential suboptimal performance due to environmental changes, as they can only use one frequency band at a time, which may become non-optimal over time.
Innovation Solution
A system and method that allows electronic devices in the network to perform quality tests on multiple frequency bands, collect data, determine the optimal band, and switch to it automatically, with a control device coordinating the process to ensure synchronized changes across all nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the network uses a single frequency band for communication, then device complexity is reduced and manufacturing cost is lowered, but network performance degrades when environmental conditions change
Solution Approach 1:
The patent implements dynamic frequency band selection by enabling nodes to switch between different frequency bands based on real-time quality assessments. The system transitions from a static single-band configuration to a dynamic multi-band system where the active frequency band can change according to environmental conditions, resolving the contradiction between manufacturing simplicity and performance reliability.
Solution Approach 2:
The patent changes the operational parameter of frequency band selection from fixed to variable. Nodes assess communication quality on different frequency bands and switch bands when quality degradation is detected, allowing the system to adapt to changing environmental conditions without requiring complex multi-band hardware in each node.
2Reliability
If the network dynamically switches between multiple frequency bands, then network performance is maintained under varying environmental conditions, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements dynamic frequency band selection by enabling nodes to switch between different frequency bands based on real-time quality assessments. The system transitions from a static single-band configuration to a dynamic multi-band system where the active frequency band can change according to environmental conditions, resolving the contradiction between manufacturing simplicity and performance reliability.
3Ease of operation
If all nodes use the same frequency band simultaneously, then communication coordination is simplified, but the network cannot adapt to frequency-specific environmental interference
Solution Approach 1:
The patent implements a feedback mechanism where nodes assess communication quality on different frequency bands and report back to the network. Based on this feedback, the network coordinates frequency band switching to ensure all nodes operate on the same band, maintaining coordination simplicity while adapting to environmental conditions through quality-based feedback loops.

AI summary
The invention particularly relates to a method executed by a control device for a mesh communication network, which allows an optimal frequency band to be selected, the method comprising the steps of determining a piece of network quality information, if the quality information is below a first threshold, then: transmitting a message to each device in the network comprising an instruction to perform a frequency band quality test, collecting quality data for each frequency band for each device at the end of the quality test, determining a quality indicator for each frequency band, and selecting a so-called optimal frequency band, which is the frequency band associated with the best indicator, when the so-called optimal frequency band is different from the frequency band in use, then transmitting an instruction to use the so-called optimal frequency band to each device.
