Hypothetically, near instantly. Realistically, I don’t think someone is going to bother to triangulate a random burst in the 2.4 and 5ghz bands, but someone logging radio traffic for shits and giggles would certainly notice 5-10 minutes bursts of noise early in the mornings saturating the band (you’d need to do the whole band as modern WiFi will channel hop for the best signal).
