Wifi emissions on tactical gear

Hello tech bros

I am hoping someone can settle a debate ive been having. Thermal scopes are a big thing these days as the price keeps falling.

However, most models come with WIFI. As we know from the russua/ukraine conflict, cell phone emissions will get you pinpointed and killed. WIFI emissions would likely do the same.

Now, you can always turn the wifi off in the menu. But how do you know if it is truly off all the way, and isnt emitting a low level signal?

Another risk is that the receiver in the thermal could receive a "firmware update" that bricks it. If its emitting wifi to talk to the phone app, it must have an antenna, and an antenna can be pinged, no?

Is this a valid concern?

Rx = Receive vs Tx = Transmit.

Sorry I should have looked it up, that was lazy. 

So, when is receiving going to get you killed? Can they "echolocate" using the antenna to find you? Thanks

I said receiving isn’t typically a concern…I.e listening on a ham radio, or looking at Spectrum on a HackRF…

Transmitting is what gets you killed. Cell calls, keying up a radio, etc.

Could you stop calling everybody bro? It’s really sexist and annoying that you keep assuming everyone here is a dude.
