What is Wi-Fi Direct and how can it be used?

Wi-Fi Direct

Wi-Fi Direct

If you are using an Android phone, you may see an option called Wi-Fi Direct at the top of the screen in the WiFi section in the sharing menu or when you are connected to a WiFi network. Wi-Fi Direct is a Wi-Fi standard that allows your device to connect to other devices and share information between other devices without the need for internet or a wireless modem.

This feature was first introduced with version 4 of the Android operating system, but after being welcomed by users, it spread to other mobile operating systems such as iOS and Windows Phone. Lack of special configuration and compatibility with different hardware were two important factors that made this feature so widespread.

Before you can use the ability to share files over Wi-Fi Direct, you need to make sure that both devices support this feature. If none of the file-sharing devices support this feature, the file-sharing process via Wi-Fi without the need for wireless Wi-Fi access is still possible, relying on another feature included in the Wi-Fi Direct and Portable subset. The name Hotspot will be applicable. Portable Hotspot and Wi-Fi Direct both use the same technology.

In Portable Hotspot, a device manually converts to a mobile router and provides a wireless network that other mobile devices that support Wi-Fi connectivity can connect to. In such cases, it is possible to implement a number of security features such as data encryption to increase the security of data transmission to connect to Hotspot.

In WiFi Direct, two devices are able to connect to each other without any encryption process. In this case, the connection is done automatically and without the need for special work.

 Now that you are familiar with these two features, it is time to take a practical look at how these two features work.

Wi-Fi direct on iPhones and iPods

Wi-Fi Direct capability with iOS7 and later was made available to iPhone, iPod and iPod Touch users. This feature is known on the iOS operating system as AirDrop. With the release of iOS8, the AirDrop feature was developed and supported by Mac computers. AirDrop, which uses Wi-Fi Direct internally (with Bluetooth), allows users to exchange high-speed wireless data with other iOS-compatible and compatible devices.

Wi-Fi Direct on Android phones

In order to be able to use this feature on Android devices, you have various user applications. Note that on your Android device you do not have to deal with the limitations of the iOS operating system. Applications used to manage files (File Manager) allow you to use the WiFi Direct feature to exchange information between different devices. But if for various reasons the device you are using does not support WiFi Direct, then you can use the SHAREit app. Relying on WiFi Hotspot capability, this program creates a powerful wireless network. Then the destination device, which is not able to support wiFi Direct, connects to this hotspot network, and thus the SHAREit program transfers files between the two devices. But how can we enable the WiFi Hotspot feature on the source Android device? To do this, follow the steps below.

The first step is to first enter the settings of the Android device on which you want the Hotspot feature to be activated.

Step 2: Touch Connections on your Android phone. Scroll down the page, then select and Terhering, and then enable Mobile Hotspot.

Step 3 Now touch the Password field and select the password for the network you created. In the name field you can also specify a name for your network instead of the default name.

You can now create a Wi-Fi connection between Wi-Fi devices based on the hotspot you have created and share the data between the devices. Note, however, that in this case only devices that have the password and username are able to send information. SuperBeam is another powerful application that uses Wi-Fi Direct technology to transfer files between devices that are compatible with this technology. For applications that are not compatible with this feature, the program automatically generates a portable hotspot based on the host WiFi network.
