So there appear to be a few small DCC shops that make a wireless battery driven variant. What I get is that these send the DCC command codes through an RF interface to their board in the loco. The board is connected to battery power and "chops in" to the DC voltage the various 1s and 0s to encode the signalling in to it.
That output then goes -- shazam -- into the DCC decoder ... instead from track power. (kinda nifty really!)
The "win" being you can use any DCC sound decoder (which are misnamed because they all provide motor control too or so it seems)
And, well, that's kinda cool if you want to upgrade to new sound boards, etc...
Other than this -- probably no real benefit. I mean if you want remote control there's 4 bazillion ways to do it. And regular DCC is wireless or can between the remote and base station -- but goes over the track otherwise to the local. Kinda like that other system we know about ...
It should be mentioned that O has power requirements few but some DCC sound board people support in a limited fashion, or so it appears -- and its' not clear if the wireless varients will work with these cards.
