Welcome to the forum. That is a more complicated question than you may think because there are so many answers and there are new things on the market.
I have Digitrax Super Chief with radio and I love it. It is not the least expensive, but it works pretty well.

I actually had a wireless layout early in my modeling career - totally scratchbuilt, 5DC, 1:196 scale. (Translation - built with bits of wood and cardstock, moved by the five-digit non-electric propulsion system.)
At the opposite extreme, the SVLS 'layout' in Rancho Cordova was also wireless. It was ride-on live steam.
Several decades ago a modeler whose name escapes me built a radio controlled A-B set of covered wagons in HO, powered by on-board batteries. It was demonstrated to Linn Westcott on a restaurant tablecloth (with not a rail in sight.)
Seriously, all of the powered/controlled systems currently in use, including those which use radio-link or infra-red remote hand units, have under-layout (or on top of the layout) wiring to get power (and DCC signals) to the locomotives. So, that form of 'wireless' layout - isn't.
