Does WhatsApp web require the computer and phone to be connected to the same wifi network simultaneously?

Assume I've already authenticated and used WhatsApp web - then taken my phone outside the house (miles away, no chance of it still being connected to WiFi). Now I log back into WhatsApp web, would it still work?

Reason I ask is that I've lost my phone and yet WhatsApp web was still working (until the phone died). So I'm wondering whether it's actually lost (outside the house - many miles away) or whether it's actually hiding in the house somewhere and was actually still connected to the WiFi network (until it died).

I've successfully used it whilst my laptop was connected to home WiFi whilst mobile was connected to mobile data. It wasted more data but it still worked.
