Wi-Fi Alliance starts certifying tunnel technology for better wireless performance
The Wi-Fi Alliance has launched a program to certify 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, removing the need to transmit data through the access point, and avoiding delays caused by congestion, the organization said on Thursday.
The new TDLS certification program can improve performance for applications such as media streaming, without requiring user intervention, according to Wi-Fi Alliance.
A direct link between wireless devices may sound reminiscent of the functionality offered by Wi-Fi Direct.
But the two technologies are complimentary, according to Wi-Fi Alliance. 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.
Many products will be certified for both TDLS and Wi-Fi Direct, but the two technologies will be used in different situations, Wi-Fi Alliance expects.
