Abstract: The disclosed technology addresses the problem of testing performance of RU scheduling algorithms used by an OFDMA enabled AP to support multiple clients, using a two-armed test harness with a wired connection to one side of an AP under test and multiple wireless clients coupled in RF communication with the AP. The wireless clients can be connected over the air or conductively to antenna(s) of the AP under test. The test harness generates test traffic. A sniffer radio listens to RU allocation and schedules traffic broadcast by the AP to multiple clients. A recording module records the RU allocation and traffic and a report generator categorizes the recorded resource allocation with the scheduling traffic heard by the sniffer radio and provides resource allocation statistics. The wireless clients are connected conductively or OTA to antennas of the AP under test. One sniffer radio replaces multiple sniffers used in prior test systems.
