Solution Overview
Problem
Point-to-point communication networks face challenges in diagnosing and mitigating out-of-band interferers, which cause performance degradation and require costly onsite visits and disruptions in transmission for spectrum analysis.
Innovation Solution
Integration of a spectrum analyzer into outdoor point-to-point communication units, equipped with a direct-conversion receiver and digital signal processor, allows for digital capture and remote monitoring of diagnostic information, reducing the need for manual equipment connection and minimizing transmission interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual spectrum analysis is performed by connecting external equipment to outdoor units, then diagnostic accuracy is improved, but transmission disruptions increase and operational efficiency decreases
Solution Approach 1:
The patent combines the spectrum analyzer functionality directly into the outdoor communication unit by integrating a receiver and digital signal processor. This merging eliminates the need for external equipment connections and manual intervention, allowing continuous spectrum monitoring without transmission disruptions while maintaining diagnostic accuracy through built-in digital capture and analysis capabilities.
2Measurement precision
If external spectrum analyzing equipment is used for diagnosing out-of-band interferers, then measurement capability is improved, but device complexity and cost increase
Solution Approach 1:
The outdoor communication unit is designed with multi-functionality, incorporating both communication functions and spectrum analysis functions within a single device. The receiver and digital signal processor serve dual purposes: enabling normal communication operations while simultaneously providing spectrum monitoring and interferer detection capabilities, thereby eliminating the need for separate external analysis equipment.
3Reliability
If continuous transmission is maintained for network availability, then service reliability is improved, but ability to perform spectrum diagnostics deteriorates
Solution Approach 1:
The integrated spectrum analyzer enables continuous spectrum monitoring to occur simultaneously with continuous transmission operations. The digital signal processor continuously captures and analyzes signals in the frequency band of interest without requiring transmission interruptions, ensuring both network availability is maintained and spectrum diagnostics remain accessible at all times.
