How does Nordic measure WiFi throughput?

Hi Sir

Please tell me about the environment for wifi measuring and used samples.

I wrote a TCP server and TCP client running on two separate 7002DK boards.
TCP client send 2k bytes datas to TCP server per millisecond.
TCP server print out the amount of data received per second.


The result is as follows.

But the results are not matching the ideal outlined in the Nordic documentation.


I also try the zperf shell sample github.com/.../overlay-zperf.conf
The result is around 5.1 Mbps.

Thank you.

  • Hi, 

    We don't expect those numbers to be reached with an nRF5340 host. They merely indicate what the nRF7002 QSPI interface could achieve if the host was not the limit.

    How do you test with zperf? Do you run zperf on two kits or run an "iperf" client on his PC? To test zperf, it requires iPerf 2.0.5 installed on the host machine or two supported kits.
