TDLS

TDLS, or Tunneled Direct Link Setup, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network."

Wi-Fi Alliance added certification for TDLS in 2012. It describes this feature as technology that enables devices to link directly to one another when connected to a traditional Wi-Fi network. "Wi-Fi CERTIFIED TDLS devices can set up secure links and transfer data directly between them. TDLS-linked devices benefit from an optimized connection to do things such as streaming video or synching content, without burdening the network as a whole."

The IEEE has endorsed this as the 802.11z standard.
