If I'm correct, It's a 5GHz connection between the GamePad and console. Many Wifi routers today can offer that speed.
That said, if the Wii U could identify your 5Ghz router and stream data throughout the network, potentially you could boost the signal to everywhere you have a stable 5Ghz wifi connection present in your home. No new hardware really needed.
I predict NX launches in 2017 - not 2016
