  • Patent number: 11917422
    Abstract: An information handling system executing an intelligent throughput performance analysis and issue detection system may comprise a network interface device to establish a wireless link with a wireless network and a processor to execute a neural network trained to predict wireless link throughput values based on controlled connectivity testing metrics gathered in a controlled laboratory from tested information handling systems. The processor may gather measured throughput of the wireless link and operational connectivity metrics for the information handling system that describe antenna positional information, antenna adaptation controller parameters, signal strength measurements, and wireless link performance metrics. The neural network may output, based on the gathered operational connectivity metrics a predicted throughput value that differs from the measured throughput by a maximum tolerance.
