LO Frequency of WiFi Chip

[DingDangDoong]

Hello All,

I've recently become interested in radar-detector-detectors, they are devices that can be used to detect if a radar detector is being used to check for speed traps. I know they work by detecting local oscillator leakage from the radar detector and I want to see if that is possible for WiFi modules. That capability could be really useful for hardware cybersecurity efforts.

I've read the data sheet of the RL-SM02BD that is on here and it did not explicitly say what the chip uses for the LO its RF front end. Before I start going crazy with the VNA I wanted to ask if anyone here has more insight into this chip's operation? I don't know all that much about it.

If that would be possible with the chips used in mobile phones, I am pretty sure that such an app for other phones would have been offered.
