To start with, the console has two separate Wi-Fi chips: one for communicating with the local Wi-Fi router and the other exclusively for communication with the GamePad.
The console-to-GamePad link operates exclusively over the 5GHz band, the set of Wi-Fi frequencies with the most channels and the least interference. To talk to the home router, the console can use either 5GHz or the other band, 2.4GHz. If necessary to prevent interference, the console-to-router connection can be forced onto the 2.4GHz band, said Dino Bekis, senior director of Broadcom's Wireless Connectivity Combo unit.
