Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spectrum analyzers are used, then measurement precision is improved, but device complexity and ease of operation worsen due to requiring trained engineers
Solution Approach 1:
The patent introduces an intermediary processing system that sits between the RF sensors and the user interface. This intermediary automatically processes raw RF data, performs spectrum analysis, identifies interference patterns, and presents simplified results to users. This mediator handles the complexity of RF analysis while presenting an easy-to-use interface, resolving the contradiction between measurement precision and ease of operation.
Solution Approach 2:
The system performs self-service by automatically conducting spectrum analysis, identifying used and unused frequencies, and generating recommendations without requiring user expertise. The automated processing engine independently analyzes RF data patterns, applies coordination algorithms, and delivers results, enabling novice users to access professional-grade spectrum analysis capabilities without training.
2Measurement precision
If conventional spectrum analyzers are used, then measurement precision is improved, but device complexity and cost worsen
Solution Approach 1:
The patent segments the spectrum analysis function into distributed RF sensors that collect data independently, a central processing engine that analyzes the data, and a user interface that presents results. This segmentation allows each component to be optimized independently and enables the system to achieve professional-grade analysis accuracy through coordinated simple components rather than requiring a single complex expensive instrument.
Solution Approach 2:
The system uses multiple low-cost RF sensors that copy the basic frequency detection function across multiple nodes. Rather than relying on a single expensive spectrum analyzer, the patent deploys multiple simpler sensors that collectively provide comprehensive spectrum coverage through data aggregation and collaborative analysis, reducing overall system cost while maintaining measurement precision.
3Reliability
If continuous monitoring is implemented, then reliability is improved, but use of energy worsens
Solution Approach 1:
The patent implements periodic monitoring where RF sensors continuously scan the spectrum at regular intervals rather than maintaining constant continuous monitoring. The system captures RF data at periodic sampling rates, processes this periodic data stream to identify frequency usage patterns over time, and updates coordination recommendations periodically. This periodic approach maintains reliability by detecting frequency changes and interference events while significantly reducing energy consumption compared to truly continuous monitoring.
Data Source
AI summary
Systems and methods are provided for analyzing radio frequency (RF) data. RF data is received from one or more RF sensors, wherein the RF data is collected over a particular frequency range and resolution bandwidth. One or more frequencies not in use are determined based on the RF data and a signal level threshold. One or more recommended frequencies for use are calculated based on the one or more open frequencies and an intermodulation function, wherein each of the one or more recommended frequencies reduces a potential for intermodulation distortion than other frequencies in the frequency range.
