TWT: an Innovation for the IoT

TWT: an Innovation for the IoT

There’s always a specific tiny dread when you go to take a picture or are hoping to make one last call and you see the battery percentage on your device inching downward. We spend a lot of time thinking about how to squeeze every last selfie and live video from our devices: we trade tips with our friends about turning off data and location sharing for certain apps running in the background, we scour tech sites and columns that tell us to limit streaming video or use certain apps while close to a power outlet. And we’re not alone: according to a survey of US smartphone users conducted by YouGov late last year, the single feature which appealed to most respondents was a longer battery life – ahead of shatterproof screens, water resistance and better cameras. As we take advantage of all the awesome (and more demanding) emerging applications, battery life is an issue for most of us.

Device makers know: they’ve come up with a number of innovations to boost battery performance (and keep our devices small and manageable) with features like quick charging to bring our phones back to life when the battery reaches the limit. Max WiFi is Wi-Fi’s opportunity to contribute.

The new Wi-Fi generation implements a technology called Target Wake Time (TWT), which enables phones and other devices to turn off their radios when not exchanging data, significantly reducing drain on batteries.

With current Wi-Fi technology, a smartphone or another device has to look out constantly for others and wait until there is an opportunity to transmit. Even when our Wi-Fi devices are idle, they wake up periodically to check if there are any messages waiting for them. Many apps are constantly checking for information in the background, notifying you of new messages or downloading data—which can burn through your battery life even when you aren’t paying any attention to them.

With TWT, a time to transmit or receive data is predetermined, so a device can sleep until it is its turn—significantly reducing battery consumption. With popular apps like FaceTime not transmitting data for 95 percent of the time, even when they are in use, this translates to a significant drop in Wi-Fi battery drain due to Max WiFi.

Max WiFi promises our devices up to seven times better battery life. Imagine the possibilities.

And it’s not just our phones and tablets: we have more and more devices connecting to the network every day. With Max, our connected thermostats, doorbells and cameras have better energy efficiency too.

It’s just another way Max WiFi helps us do more.
