What are the ways to transfer files by mobile phone?

Nowadays, the mobile Internet is developing rapidly, and speed and convenience are the main contributors. With the needs of daily life and work, data transmission between mobile phones, iPad, notebooks, etc. It is becoming more and more frequent, so how can a mobile phone wirelessly connect to a computer to transfer files? If you are still using a long USB cable to connect a computer to transfer files, then you are Out! Next, I will bring you the method of wireless file transmission between mobile phones and computers. Welcome to share.

Bluetooth article

As the most traditional transmission mode, Bluetooth is widely used in Android. In addition to transmitting some content between mobile phones or between mobile phones and PC, Bluetooth is also widely used in peripherals. Users can install keyboards, mice and even Bluetooth watches for Android phones through Bluetooth pairing, which is relatively convenient to use. However, as the most traditional transmission function, Bluetooth is still troublesome to use.

The advantages of Bluetooth are basically known to everyone. Bluetooth can be said to be the most basic transmission mode. When using Bluetooth for transmission, mobile phones need to be paired, and the transmission distance of Bluetooth depends on the situation. However, for short-distance sharing, the restrictions of Bluetooth application are still relatively small, and most of the content supports sharing using Bluetooth. Another advantage of Bluetooth is its support for connecting devices, which we mentioned just now.

After talking about the advantages and disadvantages, Bluetooth is a point-to-point transmission, and Bluetooth can only be shared between two devices, which is the biggest disadvantage of Bluetooth. At the same time, the transmission speed of Bluetooth is limited. Obviously, the development of Bluetooth transmission speed can't keep up with the growth of media capacity, and Bluetooth may be gradually eliminated.

Wi-Fi articles

Besides Bluetooth, we usually use Wi-Fi as the transmission mode. Usually, a mobile phone and a PC can be connected through Wi-Fi, and the two devices can be synchronized in the same Wi-Fi environment. This synchronization process is not supported by Android itself and needs the help of third-party tools. (The tool I use here is Tencent File Manager)

Wi-Fi transmission is much faster than Bluetooth transmission, and it is also more convenient to transmit multiple files at the same time, especially when operating the mobile phone on the computer side, there are few softwares on the mobile phone to access the files on the computer side. Motorola's MotoCast can directly access the contents of folders on the computer through the mobile phone, but there are still a few softwares that have this function.

Wi-Fi transmission requires two devices in the same Wi-Fi network environment, which requires high transmission, and there is little software that can be accessed between mobile phones under the Wi-Fi network. After all, the privacy of mobile phone users should be protected. If users want to transfer content from one mobile phone to another, we need other methods.

Cloud transmission article

The use of cloud for file transmission has become the mainstream, mainly because almost every platform can eat cloud services, and there are enough service providers providing cloud transmission, which are selective and easy to use. The operation of cloud transmission depends on each service provider. At the same time, many mobile phones have built-in cloud transmission functions, such as Motorola's MotoCast function.

Cloud transmission is a cross-platform service. As long as the service provider provides it, whether it is PC, MAC, iOS, Android or WP7, you can use cloud services. The transmission speed of cloud service depends on the network situation and service provider, and the supported file types are also controlled by cloud service. However, cloud transmission service is more free, whether it is between mobile phones or between mobile phones and tablets, it will be relatively free.

Speaking of pros and cons, first, if there is no Wi-Fi network, using cloud transmission services will consume a lot of traffic. After all, applications and media files on mobile phones are not small now, which is also the biggest obstacle to cloud transmission. At the same time, the space provided by cloud transmission service providers is limited, and the size of a single uploaded file may be limited. If the picture is uploaded, it may be compressed. It can be said that there are many uncertainties in cloud services. Although it is developing rapidly now, there are still many problems to be solved urgently.

NFC article

NFC near field communication technology has become very popular recently, especially in Android 4.0. The appearance of Android Beam makes NFC more powerful. China also tried Android Beam function in detail on Android 4.0, which also made NFC near field communication more practical. (details)

At present, the NFC function is limited to the transmission between mobile phones, which requires the NFC sensing areas of two mobile phones to collide. In fact, the function itself is still very limited, but the experience is really fresh, which is also the biggest advantage of NFC. In addition to using NFC between mobile phones, there is also a special NFC tag that can also send instructions to mobile phones.

Android phone NFC tag game

In fact, the NFC function cannot transmit any form of files. It can only transmit one label. At present, the biggest information transmitted is a business card, and there is no way to transmit media files. Although Samsung's new S Beam uses NFC function, it actually uses another function for transmission. Next, we will introduce it to you. As for the NFC function, I still think it is too small if it is used between mobile phones, and it is more practical to use it with some tags.

Finally, you may use less wireless direct connection technology, which can connect multiple devices in the same environment without restriction, and the transmission speed is very fast, which may become the most commonly used transmission technology in the future, but there are not many relative applications at present, and you may not know much about it. The tool I use here is a quick tooth.

Wi-Fi Direct is a technology that takes one device as a hotspot to establish an offline LAN, and other Wi-Fi enabled devices can transmit after enjoying the network. The transmission speed is fast, and multiple devices can be connected simultaneously. It is recommended that users install fast teeth to experience and transmit multiple files at the same time, which is very good for multiple users to share.

The disadvantage of Wi-Fi direct connection is also obvious. The most terrible thing is that it costs electricity. The main reason is that the built-in mobile phones in hotspots will become very short-lived. At the same time, other mobile phones connected to hotspots cannot access other networks because the devices are already connected to the local area network. One way to surf the Internet is to set up a mobile phone in a hot spot to open 3G data. However, because Wi-Fi Direct is an open network, it is undefended. If someone steals it, the traffic fee will be washed away.
