New features of iOS 7: cellular data and Wi-Fi connection can run simultaneously

The official version of iOS 7 has a new feature that was not found in the beta version: cellular connection, Wi-Fi connection and Bluetooth connection can run simultaneously. Technically called "multi-channel TCP" (mulTIpath TCP). According to reports from 9to5mac and MacLife, iOS 7 provides a new connection feature that allows seamless switching between multiple connection forms.

If 4G or 3G is turned on at the same time, Wi-Fi and Bluetooth are connected to the network, then iOS 7 can run these three connections at the same time. If the quality of the connection being used is unstable, then iOS 7 will automatically switch to the line with a good connection quality To ensure the smooth running of certain apps. Such as FaceTIme or iTunes radio. 9to5mac concluded that "iOS 7 is the first commercial software that implements and provides MCTCP."

At present, if other mobile Internet terminals are disconnected, the line switching will temporarily interrupt the connection. For example, if you are watching a Youku video, you will see the video paused and rebuffered. The "multi-channel TCP" technology can ensure that your viewing experience is not affected by disconnection.

Students who have upgraded to iOS 7 but do not have an unlimited data plan must now pay attention to their usage habits. If you do nâ€™t have the habit of turning off 3G / 4G, then when the Wi-Fi signal is weak in your place, iOS 7 will make you automatically go to your 3G / 4G line.
