WiFi Direct: A better way to transfer files

Updated on July 27, 2015

Smart phones give us the opportunity to record and share the great moments of our life with friends and family members. Before Bluetooth and WiFi P2P technologies, there was not many choices apart from using USB or email. As everybody knows, USB is one of the main culprit in distribution of computer viruses and malwares. Also sending files by email has its own restriction; for example, one cannot send a large file via email and internet access may not be available. Solving such a problem was the motivation for invention of Bluetooth technology. But in any factor and measure, the old Bluetooth is far behind the new WiFi Direct technology. Just to mention a few:

  • The speed of Wi-Fi Direct promises transferring data up to 250Mbps, while Bluetooth 4.0 hardly reach to 25Mbps.
  • Wi-Fi Direct has a range up to 200 meters. While Bluetooth maximum range is just 10 meters.
  • From security point of view, Wi-Fi Direct uses AES 256-bit encryption, while 4.0 is using AES 128-bit encryption.

Considering all aspects and specially the speed of transferring data, Wi-Fi Direct is the tool of choice for transferring data between deices. Unfortunately, not all devices have a built in Wi-Fi Direct software and majority of users depend on third party tools. There are many WiFi Direct apps in Google, but here we choose an app that is free and easy to use. We tested it to transfer file between different manufacturer devices and it pass all the tests.

Step 1

First install a WiFi Direct app from Google Play app store.

Step 2

After installation and opening the app on both devices, activate the peer search process by touching search icon on the top menu.

Step 3

Choose the target device from the list of available devices. After getting and accepting invitation both devices should be able to see the file selection button on the screens.

Step 4

Touch the "Select File" button and follow the proper process in your device to select any file from saved on the device.

Step 5

The file should be seen on the target device. If the size of the file is large it may take a while to be delivered. The file in destination can be viewed by touching the folder icon at the top of the app.

As you see the method is very simple and straightforward. All step can be seen in the video below.
