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.

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.

Firmware version: 18.99.2.p49.9 to 18.99.2.p155

Component	Description
Bluetooth	Audio lost occurs due to periodic adv sync lost, during 2 BIS 44.1kHz unencrypted streams with 1M PHY configuration. BIS sync loss may occur in long audio streaming sessions.

Parent topic:Bug fixes and/or feature enhancements

Firmware version: 18.99.2.p155 to 18.99.2.p66.30

Component	Description
Wi-Fi	802.11R Fast BSS roaming works only with hostapd and does not work with standard APs (supporting 11R)
Bluetooth	DUT is not able to sustain a connection with the remote device that does extended advertisement with coded PHY configuration. When 2 CIS streams are active, after the first device disconnects followed by the second device disconnecting, the second peripheral device hangs. Audio Play/Pause does not work in BIS case.

Firmware version: 18.99.2.p66.30 to 18.99.3.p10.5

Component	Description
Wi-Fi	STAUT not sending Neighbor Advertisement packet after receiving Neighbor Solicitation packet from Ex-AP. Antenna selection time exceeds configured evaluation time
Bluetooth	When DUT works as CIS source and CIS Offset is 612us, high packet drops observed which affects the audio streaming. For BIS Source Use Cases, Periodic Interval and ISO Interval should be multiple of each other value. In 1-CIS and 2-CIS, Continuous Audio Glitches are observed with 96 kbps bit rate.

Component	Description
Wi-Fi	After performing independent reset (out-of-band mode), the STAUT fails to connect to the external AP via wlan-connect command, observed command timeout 0x107 error.
Bluetooth	Audio glitches observed with Google Pixel 7 Pro streaming audio after CIS is established with DUT. During Call Gateway (CG) / Call Terminal (CT) Use Case, the firmware periodically sends NULL PDU, which results in frequent Audio Glitch on both CG and CT sides. Heavy audio glitches observed with CIS SRC Google Pixel 7 Pro Continuous audio glitches observed in 1 CIS and 2 CIS for 48_3 and 48_4 config.
