What can we use Wi-Fi Direct for?
Wi-Fi Direct is used to allow device which are connected to communicate. So anything which can be transmitted over Wi-Fi can also be transmitted through Wi-Fi direct. For example, sharing photos, printing documents from your phone to a printer, gaming, moving media.
The video below shows how Wi-Fi enabled phones, camera, printers and tablets can communicate using Wi-Fi Direct.
Why have Wi-Fi Direct, bluetooth and NFC?
It might seem odd to have so many different ways for device to communicate, but the addition of Wi-Fi Direct is a very useful one.
Wi-Fi Direct doesn’t need any additional hardware, so in theory (if the OS you are running allows it) you can use WI-Fi direct on your current smartphone and tablet now. On the other hand NFC needs additional hardware to work which not all device have yet, also Wi-Fi direct can transfer data over larger distances, and if a wireless router is available this distance can be increased.
Wi-Fi direct is also very easy to set up either by using a simple PIN number to allow devices to connect, or in some cases a physical button which when pressed on both devices at the same time will allow a connection.
With Android smartphones now coming with NFC, Wireless charging, Wi-Fi Direct and more, we will soon no longer have any need for all those USB data cables we have lying around!
