Radio Network Health Diagnostics via Signal Parameter Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communications networks face challenges in detecting and addressing performance degradation or failure due to improper operation of radios or base stations, often only becoming apparent when the network fails completely, without providing real-time alerts for suboptimal conditions.
Innovation Solution
A network diagnostic system comprising health determining devices and a master controller that analyze signal parameters from authorized radios to determine their health and location, identifying geographically unhealthy areas within the network, and providing corrective messages to maintain network performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network operators wait for complete network failure to detect issues, then they avoid complex real-time monitoring systems, but network downtime and loss of communication increase significantly
Solution Approach 1:
The network radios perform self-diagnostics by automatically measuring their own signal parameters (power, frequency, modulation accuracy) and comparing them against specified thresholds. Each radio acts as both the monitored object and the monitoring device, eliminating the need for external diagnostic equipment and reducing system complexity while maintaining continuous reliability monitoring.
Solution Approach 2:
The system implements continuous feedback loops where radios monitor their transmission parameters in real-time, compare measured values against specified thresholds, and generate alerts when deviations occur. This feedback mechanism enables proactive detection of performance degradation before complete failure, improving reliability without requiring complex centralized monitoring infrastructure.
2Loss of time
If real-time signal parameter measurement is implemented across all radios, then network performance degradation is detected early, but the energy consumption and processing load increase
Solution Approach 1:
Instead of continuously measuring all signal parameters at maximum precision, the system implements selective monitoring where radios measure only critical parameters (power, frequency, modulation accuracy) at adjusted precision levels. Alert thresholds are configured to trigger only when significant deviations occur, reducing processing load and energy consumption while maintaining effective detection of performance degradation.
3Measurement precision
If comprehensive signal parameter analysis is performed on every radio transmission, then accurate identification of unhealthy locations is achieved, but processing time and computational resources increase
Solution Approach 1:
The system extracts and monitors only the most critical signal parameters (power, frequency, modulation accuracy) that directly indicate radio health and location issues. By filtering out non-essential parameters and focusing analysis on key indicators, the system achieves accurate location identification without requiring comprehensive analysis of all transmission characteristics, thus reducing processing time and computational overhead.

AI summary
An apparatus determining network health comprising base stations in bidirectional communication with radios, each having an identifier and transmitting a signal including the identifier. First and second health determining radios each receive the signal during normal over-the-air operation of radio and determine if the radio is authorized and, if so, determine the identifier, time-separated signal waveforms that are compared, operating characteristics from the compared waveforms, and a current location of the radio. Each of the radios determine health of the radio based on packet sniffing, a frequency deviation, or a range of deviations by analyzing the operating characteristics. After analysis results sent to the master controller from the radios indicate that the authorized radio is healthy, the master controller determines from the analysis results that a geographically unhealthy location of the network exists within the geographic area from which the authorized healthy radio transmitted the signal.
