The tech would even theoretically support extending the GamePad's use well outside the house, say to a local Starbucks, through Wi-Fi.

"Currently the Wi-Fi connection is peer-to-peer-based and using the GamePad outside the home would require a networked connection to the console; this is something that is a possibility for the future but is not in place today," Bekis said.

Even though it's a very old story it quite an interest possible feature if you didn’t already know about it. Could be great potentially great future feature for the Wii U especially with the new high capacity battery that just came out.
