It’s not a totally new idea; SRAM had a ‘3x7’ hub that was essentially a 3-speed IGH with a cassette driver. It primarily saw use as an ‘overdrive’ on small-wheel ‘bents and folding bikes, so you could get decent ground speed on 20” wheels without having to run oversized chainrings, or so you could get triple crank functionality but still run a single crank, for packaging reasons.
The wireless application is new, but not the idea.
