While being placed on a map is clearly bad, commodity WiFi is not great for anything that shouldn't be located, as it is obviously radiating in RF and will be detectable some distance further than the signal can actually be decoded. Tactical radios are specially designed for the problem. Eg using spread spectrum approaches, and plain not transmitting most of the time and only by the choice of the operator. It's possible that open source SDR could be applied, but I guess that the Ukrainian side have been supplied with military radios by their allies.
