The two differ in frequency and power and protocol. WiFi uses 2.4ghz and 5ghz bands at typically under 100milliWatts power. Cellular uses several frequencies, 700, 800, 850, 900, 1700, 1800, 1900 MHz at 0.6-3 watts power.

So first you’re talking about a 5-50x power difference. And lower frequencies travel farther than high frequencies.

Cellular data uses cell towers, while WiFi comes from a router or other WiFi transmitter that only has so much range. Cell towers only have a certain amount of range as well but since Cell towers are so big and tall and have so much power it allows them to spread the signal over a wider area and there’s more of them so depending on where you live you’ll probably be connected most of the time.
