Abstract: The disclosed technology teaches systems and methods for high fidelity emulation of a Wi-Fi environment for testing with three or more transmitters set to differing output signal strengths. The disclosed method includes using a PCAP file of captured packets from multiple stations with respective source addresses, RF bands, and channels within bands. The captured packets record metadata containing, at least, signal strength and time stamps. The method further includes analyzing the PCAP file to determine pairs of source addresses and channels, evaluating the pairs for signal strength, and allocating the pairs to three or more transmitters based on grouping by at least the channels and the evaluated signal strengths, and using the time stamps on the captured packets, replaying with synchronization over the transmitters at the set output signal strengths. The PCAP file can include packets from multiple protocols, and time-varying pairs with varying signal strength overtime.

Abstract: The disclosed technology teaches creating a real time visualization and analysis of Wi-Fi performance and behavior of a DUT in wireless communication with a selected Wi-Fi test device. Also included is performing a radiated test of the DUT using transceiver signals from multiple test antennas impinging on antennas of the DUT, capturing packet details of traffic between the DUT and the selected Wi-Fi test device using a sniffer that is RF coupled to antennas of the selected Wi-Fi test device, and generating a time series summary stream in real time from the packet details captured by the sniffer, including summaries of both performance and behavior metrics. The performance metrics summarize throughput and other measured characteristics of a received signal and the behavior metrics capture transmitter settings that the DUT and test devices choose. Also included is generating scrolling visualizations of selected metrics from the stream as the radiated test proceeds.
