Abstract

We demonstrate a general-purpose approach to evaluate interference immunity at the transmitter (data payload source) of a 'closed-box' wireless communication system over different time-scales. Specifically, using a consumer off-the-shelf point-to-point microwave link operating in the unlicensed U-NII-5 6GHz band as the victim system, we assess the impact of injected pulse-modulated noise with various duty cycle periods on the transmit side of a communication link. Observed distributions of link throughput show performance degradation and multimodal behaviors that are problematic for critical applications where a minimum data throughput is desired or required to maintain a given quality of service. In addition, impacts from pulse-modulated noise are observed to induce excessive impacts as compared to constant additive white Gaussian noise with the same average power, highlighting vulnerabilities on different time-scales.
