Wi-Fi Alliance starts certifying tunnel technology for better wireless performance

The Wi-Fi Alliance has started certifying products that support TDLS (Tunneled Direct Link Setup), a technology that allows devices to automatically create a link between each other after accessing a wireless network, without the need to use an access point, and avoiding delays caused by congestion.

The new technology may look similar to the functionality offered by Wi-Fi Direct. However, TDLS operates in the background of a Wi-Fi network to optimize performance, while Wi-Fi Direct devices can connect to one another while on the go, even when there is no wireless network available. Also, TDLS can operate within a Wi- Fi Direct network.

The following devices will be certified: smartphones, tablets, cameras, printers, PCs, projectors, and gaming devices. It won't be necessary to buy a new access point or wireless router for TDLS to work.

Besides streaming video and audio, TDLS can also be used to improve the performance of wireless data back-up, printing and file transfers. Chipset manufacturers including Broadcom, Marvell, Ralink and Realtek will collaborate on the integration of TDLS.
