Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network management techniques are inadequate in effectively addressing signal interference across different network devices operating on overlapping frequency bands, leading to performance degradation, and often require centralized servers or are limited to specific communication protocols, making them inefficient and impractical as frequency spectrum becomes scarce.
Innovation Solution
The implementation of a cognitive spectrum analyzer with a frequency-agile tuner, signal analyzer, and interface that detects interference signals, recommends courses of action, and allows network devices to subscribe to interference mitigation services, enabling distributed decision-making and minimizing signal interference without a centralized server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing network management techniques are used to address signal interference, then interference management is achieved, but network efficiency decreases due to centralized server requirements
Solution Approach 1:
The patent implements self-service by enabling network devices to autonomously detect interference signals through embedded spectrum analyzers and make decisions about frequency switching without requiring centralized server intervention. Each device monitors its own environment and autonomously adjusts its operating parameters to avoid interference.
Solution Approach 2:
The patent segments the centralized server-based interference management system into distributed autonomous decision-making units at each network device. This segmentation eliminates the need for a centralized server while maintaining effective interference management through local spectrum analysis and autonomous frequency selection.
2Object-affected harmful factors
If frequency band changing is used to deal with signal interference, then interference is reduced, but adaptability decreases as available frequency spectrum becomes scarce
Solution Approach 1:
The patent implements dynamics by enabling network devices to dynamically switch between multiple frequency bands based on real-time interference conditions. The frequency-agile tuner allows the operating frequency to be dynamically adjusted from one band to another, providing continuous adaptability to changing spectral environments.
Solution Approach 2:
The patent applies parameter changes by modifying the operating frequency parameter of network devices in response to detected interference levels. When interference is detected in a particular frequency band, the system changes the frequency parameter to operate in a different band, thereby adapting to the current spectral conditions.
3Stability of the object's composition
If centralized servers are used to manage network devices, then coordination is improved, but device complexity increases
Solution Approach 1:
The patent eliminates the need for centralized servers by implementing self-service architecture where each network device performs its own interference detection and decision-making. This removes the complexity of server infrastructure while maintaining coordinated behavior through distributed autonomous operations.
Solution Approach 2:
The patent segments the network management function from a centralized server into individual autonomous devices. Each device independently performs spectrum analysis and frequency selection, eliminating the need for complex centralized coordination systems while maintaining stable network operation through distributed intelligence.
