Radio Node Spectrum Management for Abnormality Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radio communication systems face disturbances due to internal and external interference, leading to reduced data rates, especially in electromagnetically disturbed environments, despite the use of frequency hopping techniques.
Innovation Solution
A radio node with two radios operating in different frequency ranges, each equipped with sensing modules that feed data to a common spectrum management module to identify abnormalities, which then controls the first radio to transmit information messages for adaptive frequency adjustments, ensuring maximum data rate and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frequency hopping is used to deal with disturbances, then reliability is improved, but data rate is limited due to transmission capacity reduction
Solution Approach 1:
The patent implements dynamic frequency selection by enabling radio nodes to sense the spectrum and dynamically switch between different frequency ranges (first and second frequency ranges) based on real-time disturbance conditions. The common spectrum management module dynamically determines which frequency range to use for communication, allowing the system to adapt to changing electromagnetic environments and maintain both reliability and data rate.
2Area of moving object
If multiple frequency ranges are used to ensure coverage, then area of moving object is improved, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by equipping radio nodes with both a first radio for the first frequency range and a second radio for the second frequency range, along with a common spectrum management module that coordinates both radios. This universal design allows a single radio node to operate across multiple frequency ranges, providing extended coverage area while managing complexity through a common management architecture.
3Reliability
If sensing modules are added to detect abnormalities, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges the sensing functionality into a common spectrum management module that coordinates with both the first radio and second radio. Rather than having separate sensing modules for each radio, the system combines sensing and spectrum management functions into a single integrated module, improving abnormality detection capability while reducing overall device complexity.
