Most households have a single Wi-Fi router in charge of numerous Wi-Fi devices. The problem is that most routers can only handle so many signals at the same time very well. It can be sending or receiving from a limited number of devices during any one cycle, and therein lies the problem. If Joey is streaming Netflix while Mom is Skyping, both can be compromised as data is missed during the flips between sending and receiving and devices.

With Tunneled direct link, Wi-Fi devices will smartly analyze the current network conditions, and switch to higher power consumption modes if the needs to transmission quality demand it, forming a direct P2P link between devices. From the press release:

The Wi-Fi Alliance® today announced that it has launched the Wi-Fi CERTIFIED™ TDLS program. TDLS (Tunneled Direct Link Setup) devices are able to automatically create a secure, direct link between them after accessing the Wi-Fi® network, removing the need to transmit data through the access point. In today’s Wi-Fi networks, faced with increased traffic and more demanding applications, TDLS links between devices improve overall network performance, reduce latency caused by heavy AP traffic, and avoid interference, thereby improving the user experience.

The new certification program will provide networks and users with the following benefits:

Increased performance: TDLS links optimize the performance of applications running over Wi-Fi networks by avoiding delays caused by queuing and congestion through an AP
Ease of use: TDLS links are formed automatically, with no user action required to set them up
Optimized communication: TDLS-linked devices are able to communicate using the highest-performance technology common to them, even if the network’s AP only supports a lower-bandwidth form of Wi-Fi
Highest available security: TDLS links are protected by the highest level of security supported by both devices, even if the network’s AP does not support that level of security
Power saving mechanisms: When battery-operated devices participate in a TDLS link, they can take advantage of advanced mechanisms to save power

“The new TDLS certification program will improve the user experience with advanced applications such as media streaming, without requiring user intervention,” said Kelly Davis-Felner, marketing director of the Wi-Fi Alliance. “Wi-Fi CERTIFIED TDLS is another example of how Wi-Fi technology keeps pace with the evolving demands of the marketplace.”

Given the trouble inherent with (or, in some cases, the logistical impossibility of) running wired networks, there looks like there’s a bright future for this technology as more and more media is housed on tablets and other portable devices. I for one embrace our new Wi-Fi overlords, and look forward to the hassle-free performance boost it claims to offer.
