Then let us take a look at AirDrop.

What is AirDrop?

AirDrop is a function for short-distance wireless transmission of data under Apple's iOS and Mac OS systems. It was released from Apple's 2013 WWDC conference. The earliest supported iOS device is the iPhone 5, and its official name in China is currently Airdrop delivery (for uniform title, this article will always use AirDrop).

How does AirDrop work? Must it be used in the same WiFi environment?

First of all, AirDrop does not need to be used under the same WiFi. Otherwise, there is no WiFi in the subway. How can you talk to your favorite little brother, Miss Sister? AirDrop's working mechanism is divided into two parts, which is also very simple to understand. Handshake', pairing two devices, the daily power consumption of Bluetooth is very low, and the frequent search does not significantly affect the endurance of mobile devices such as mobile phones. After pairing, the data is transmitted directly through WiFi, and the speed is transmitted faster. For large file transfers can also be easily handled.

This is why if you want to enable AirDrop, you need WiFi and Bluetooth are turned on. It should be noted that the Bluetooth of the iPhone 5 that supports AirDrop for the first time has adopted the specification of Bluetooth 4.0, the latest iPhone X It is also the specification of Bluetooth 5.0. It can be seen that there are still some problems in the power consumption of Bluetooth 3.0 and previous versions.

So how do we turn on or turn off AirDrop?

Swipe up from the bottom of the screen to open the 'Control Center'. On iPhone X, swipe down from the top right corner of the screen. Press firmly or tap and hold the network settings card in the top left corner, then tap 'AirDrop'. If you are using iOS 10.3.3 or lower, tap 'AirDrop'. Then choose one of the following three:

How do we send or accept files for AirDrop every day?

What file formats does AirDrop transfer files support?

In short, it can be supported, but for iOS devices and Mac devices, there are some differences in the early days. Mac OS is a computer operating system, and its Finder is a hodgepodge. It can directly accept all files. The format is stored locally. However, in iOS devices, the permissions of each app are strictly controlled using the sandbox mechanism. Each app can only store, access and open files in its own sandbox.

Earlier, the file that was passed to the iOS device via AirDrop had to have an app that supports the file in the device before it can save the file. However, in the iOS 11 system, Apple added the own 'file' APP, which can save those files. A file that cannot be opened in the phone, but the saved location can only be in an APP or iCloud cloud disk.

How fast is AirDrop to transfer files?

We use the Mac Mini 2014 to transfer a 3GB MP4 file to iPhone X, which is about 1 meter away. According to our actual test, the daily transfer rate is about 20Mb/s, so AirDrop transmission should not be used for some large files. .
