Apple New Patent: iPhone can use Emergency call function without signal

ByInge Waring 2020-01-10 1397

Mobile phones are not only our right-hand men in daily life, but also can send emergency signals or automatic alarms to inform them of their dangerous situation in times of crisis, but at present, most mobile phones rely on telecommunications signals to send out emergency calls for help. Without the signal, they will become bricks. On January 9, according to foreign media reports, Apple has applied for a new patent, even if the iPhone does not have a cell phone signal, it can still send emergency distress signals in other ways until the rescue team arrives.

IPhone SOS

It is reported that Apple's latest patent application in the US Patent and Trademark Office shows that the iPhone or iPad can personify a device to call for help in a critical situation, especially in areas that are not covered by cellular network services, which can turn the device into an UE device, in other words, users can send a broadcast emergency signal through the device (using the broadcast channel base station in the area).

In addition, if there are no broadcast channel base stations in the area, these UE devices can even actively connect to those wireless networks and actively access them, thus inserting emergency distress signals. It is worth mentioning that if your device turns on the distress function, there is also an option for super battery life saving mode, which can help you delay the battery life of the device to the maximum extent until you are successfully rescued.
