Please help, what is the maximum bps of the RF throughput of the entire ESP32 series? [Copy link]

 

I want to use ESP32 to send data now. The data volume is about 40Mbps. Is it possible to use ESP32 to send it?

Note that it is the data (transmission) rate, not the amount of data. ESP32 supports a data rate of up to 150Mbps, but the protocol overhead must be considered. If there is some coding, the actual data rate will be lower. However, under the conditions of signal-to-noise ratio and proper programming, a data rate of 40Mbps should be fine.

Here is the relevant information from Espressif's official website. Take a look, there are some test data in it.

In addition, I posted a 150M wifi speed test a few days ago, you can also refer to it.

You can also refer to the test speeds of other netizens online.

Based on the above, we also need to consider the MCU main frequency, MCU processing other data, protocols, etc. I don't think it can meet your requirements.

The data volume is about 40Mbps. What kind of device is this? The data volume is so large.

It should be possible, but such a high rate is probably not very stable.

https://en.eeworld.com/bbs/thread-1230342-1-1.html The speed of RTL8189 is still very fast, but I want to use FPGA to send data through UDP. The SDIO protocol is not easy to implement on FPGA, so I thought of using ESP32 to only handle data receiving and sending, but I don’t know if it is enough.

I think it is not possible.

I gave you the speed from Espressif's official website. The speed you want is 40M. Wi-Fi data transmission must have at least 50% redundancy. Therefore, Espressif's chip theoretically has insufficient speed. Have you ever thought about what interface between your FPGA and Espressif's chip can reach a speed of 40M? ? ?

It can communicate with FPGA through QSPI or CAM interface. If the WIFI speed is not high enough, there is no way to do it.
