Abstract
The 6 GHz spectrum is emerging as one of the important sub-7 GHz bands for spectrum sharing. A critical issue for 6 GHz spectrum sharing is the potential for interference to existing users such as fixed microwave links (FMLs). This paper addresses this critical issue by outlining a methodology for lab-based experimentation for characterizing receiver performance and reporting the results from an extensive experimental study on the impact of interference on an FML operating in the 6 GHz frequency range. Such characterization of the FML receiver performance is one of the critical components in identifying a framework where the FML and other systems can simultaneously make use of the 6 GHz spectrum. More specifically, the impact on receiver performance of the interference created by noise-like devices on the operation of an FML is characterized. The impact of interference is analyzed by quantifying a variety of metrics including Interference to Noise Ratio (INR) and Signal to Interference plus Noise ratio (SINR) along with Bit Error Rate (BER) and throughput. The operation of the adaptive coding and modulation (ACM) mechanism is analyzed by varying the interference levels. The recovery of the links after the disappearance of interference post link failure is also investigated. The impact of interference on the FML for the signal bandwidths of 30 MHz and 10 MHz are investigated. The experimental analysis described in the paper can be used to understand the resiliency of FML receivers to interference for 6 GHz spectrum.
