How Apple Could Boost Speeds 20 Times on the Next iPhone
By David Talbot
The new iPhone breaks ground by seamlessly sharing Wi-Fi and 4G for Siri. Further tweaks could boost bandwidth 20-fold in some cases.
A wireless networking technology found in Apple’s new operating system could—if tweaked—provide a 10- to 20-fold bandwidth increase in some situations, like on a moving train or in a busy urban environment, new research suggests. The technology is called multipath TCP. It allows you to use multiple wireless networks—such as 4G and Wi-Fi—at the same time. But Apple isn’t using it fully, nor is it using an advanced version—one that also encodes the data being transmitted in new ways— recently shown to provide those dramatic potential gains.
