esp32-c3 anti-interference performance issues (IDFGH-13836) #14686

General issue report

I used esp32-c3 and other 3 wifi chips to conduct wifi anti-interference test comparison. The test topology is shown in the figure: image

The test method is to run iperf3 with tcp parameter -b 10M for 30 seconds to count the results, the wifi chip works as an AP at 2457MHz. During this period, a vector signal generate is used to generate interference of different strengths(interference frequency 2457MHz), and a programmable attenuator is used to achieve signal attenuation. The test results are shown in the figure. GTScreenshot_20241008_160747

Here are a few questions:

  1. When rssi=-40dBm, esp32 has a flow attenuation at -57dBm interference, which is earlier than other chips;
  2. When rssi=-60dBm, the interference intensity has a slow attenuation between -65dBm and -60dBm. Why is this?
  3. When rssi=-70dBm, even when the interference is very low (or even no interference), the flow of esp32 cannot reach 10Mbps;

The test results are confusing. Please help analyze it. Thank you very much!
