Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radio communication systems are inadequate in detecting sophisticated jamming methods, particularly packet sniping, which can disrupt communication between gateways and peripheral devices without raising continuous background noise, leading to undetected interference and potential security breaches in wireless communication systems.
Innovation Solution
A method that continuously measures the power of incoming radio signals using high-bandwidth detection in the receiver chain, calculating statistical values such as mean and standard deviation to identify step changes in power levels, enabling the detection of intentional or unintentional radio disturbances and generating an alarm signal to address jamming attempts, including packet sniping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alarm systems monitor radio signals for absence to detect jamming, then simple jamming can be detected, but sophisticated jamming methods like packet sniping that maintain continuous background noise go undetected
Solution Approach 1:
The patent replaces conventional signal presence/absence monitoring with a statistical power analysis system. Instead of using simple binary detection (signal present/absent), the system continuously measures radio signal power and applies statistical tests (standard deviation calculation, threshold comparison) to detect anomalies. This substitution of mechanical monitoring with statistical analysis enables detection of sophisticated jamming while maintaining system reliability.
Solution Approach 2:
The patent changes the detection parameter from binary signal presence to continuous power measurement with statistical analysis. By measuring power levels over time windows, calculating mean and standard deviation, and comparing against thresholds, the system transforms simple monitoring into a sophisticated detection mechanism that can identify packet sniping jamming attempts that maintain continuous background noise.
2Measurement precision
If continuous power measurement with high bandwidth detection is implemented, then sophisticated jamming can be detected, but energy consumption and processing requirements increase
Solution Approach 1:
The patent applies partial action by using selective statistical analysis only when needed. The system continuously monitors power levels but performs full statistical processing (standard deviation calculation, threshold comparison) only when anomalies are detected or during defined time windows. This approach achieves high measurement precision for detecting sophisticated jamming while reducing overall energy consumption compared to continuous full-power analysis.
Solution Approach 2:
The patent implements preliminary action by pre-defining detection thresholds and time windows before actual jamming detection begins. The system pre-calculates acceptable power variation ranges and sets detection parameters in advance, allowing rapid real-time detection without requiring complex on-the-fly calculations. This preliminary setup enables precise measurement while minimizing processing energy during operation.

AI summary
A method and a detector for detecting radio disturbances in a radio communication system comprising a gateway device and a peripheral device, each arranged to send radio signals to and to receive radio signals from the other. The method comprises measuring the power level (Pm) of separate information segments of the radio signals received by one device from the other device, determining a statistical value (Pd) of measured power level values, comparing a selected measured power level with the statistical value, and producing an alert signal, indicating a radio disturbance, if the difference between the selected measured power level and the statistical value exceeds a threshold. The detector comprises a power level detector (62), a processing unit (64) operatively connected to the power level detector (62), and a memory unit (66) storing a plurality of statistical values.
