Wi-Fi throughput

Throughput test setup

  • Environment: Shield Room - Over the Air

  • Access Point: Asus AX88u

  • DUT: IW612 Murata (Module: 2EL M.2) with EVK-MIMXRT1060 EVKC platform

  • DUT Power Source: External power supply

  • Client: Apple MacBook Air

  • Channel: 6 | 36

  • Wi-Fi application: wifi_wpa_supplicant

  • Compiler used to build application: armgcc

  • Compiler Version gcc-arm-none-eabi-13.2

  • iPerf commands used in test:

TCP TX

iperf -c <remote_ip> -t 60

TCP RX

iperf -s

UDP TX

iperf -c <remote_ip> -t 60 -u -B <local_ip> -b 120

Note: The default rate is 100 Mbps.

UDP RX

iperf -s -u -B <local_ip>

Note: Read more about the throughput test setup and topology in 2

The throughput numbers are captured with default configurations using wifi_wpa_supplicant sample application.

Parent topic:Wi-Fi throughput

iPerf host configuration and impact on throughput {#iperf_host_configuration_and_impact_on_throughput}

To get the highest throughput, the throughput values shown in STA throughput and Mobile AP throughput are measured with the maximum values of the default host configuration macros. STA and AP throughput captured with the minimum values of the host configuration macros shows the throughput numbers obtained when using the minimum values of the host configuration macros. The macro values are defined in lwipopts.h file.

The table below lists the minimum and maximum values of the host configuration macros.
