Turn a WiFi 7 Router into a 320Msps Software Defined Radio Receiver

What do normal people use SDRs for? I'm genuinely curious. Or is it just cool to do?

FYI, since it's the same chipset I'm pretty certain this will work on the Banana Pi R4, which has built in PCIe for NVMe.

This same devloper also built an SDR out of an ESP32 Wi-Fi microcontroller [1], this is awesome!

This development makes me hope that we'd be seeing more of these on common Wi-Fi cards, so that every random laptop could be used as an SDR for many fun and useful applications on a budget.

Wow that's super cool! It's not DC to daylight but I sure don't know a cheaper way to get a 320 Msps receiver at 5 GHz.

With the right upconverter, that's amazing. It wouldn't take much, really, a phase locked vco from 5 to 10 ghz, mixer, and a 4ghz low pass filter to turn it into the basis of a 4 Ghz communications service monitor.

I can't keep up with the rapid, non stop cool stuff being discovered! Someone figured out how to get the ESP32 to transmit, at lower bandwidth (I think I read 200-250khz) I don't know which project it was but there are a bunch on this site:

Thanks claude

wow, could this be turned into a 2.4ghz SAR? I always wondered if it’d be possible to use something like that to pick up wifi signals from much farther away. Of course a more sensible choice would just be to use a yagi antenna

What is the radio quality like SNR?

Anyone know how to get ahold of a device in Europe?

Am I understanding that this is doing something the chipset wasn’t designed to do?

I’m not seeing a synopsis of the significance of this, for the uninitiated

What is Msps? I’m not familiar with that scale

An accurate description is "turn an SDR into an SDR".

Now if you could also make it transmit such samples a few of those could make a nice DIY phase array for some of the most fun bands to play with.
