What is and How It Works the Wi-Fi Direct?

The world is abandoning the cables, but the Wi-Fi and not the Bluetooth that we know and love is not always the best way to connect devices. Wouldn’t it be great if you could easily connect Wi-Fi devices, without interfering with access points and lengthy passphrases? This is what promises to the Wi-Fi Direct.

Wi-Fi Direct is a Standard Suitable

He came up through the Wi-Fi Alliance, the industry association world in charge of certifying kits Wi-Fi.

Wi-Fi Direct is Wi-Fi, No Part of the Internet

The idea behind Wi-Fi direct is that simple tasks need connections simple. For example, you may want to print from your laptop or smartphone to a wireless printer, share images with another person in the same room or to stream video from your phone to your TV. None of these things requires a connection to the internet, but they need to connect with the printer, the hardware of the other person or with the TV. With the Wi-Fi Direct, it is more easy and fast also.

Wi-Fi Direct You Can be Part of the Internet Also

If you have a Wi-Fi router connected to the internet, you can connect to the network also.

Wi-Fi Direct Does Not Need a Wireless Access Point

Wi-Fi Direct devices can connect to each other without having to pass through an access point: they can establish ad-hoc networks, when necessary, allowing you to see what devices are available and choose which one you want to connect. If this sounds very much like Bluetooth, is because it is.

Wi-Fi Direct uses Wi-Fi setup Protection

You do not want any person to be able to connect to your hardware. for example, you may not want to see what the neighbors are passing on the TV of them on your TV. Thus, Wi-Fi Direct uses Wi-Fi Protected Setup, and WPA2 to prevent unauthorized connections and to keep your communications private. There are two ways to establish a connection: with physical buttons (press the button on gadget X and then the same in a device Y), or with PIN codes.

Wi-Fi Direct Knows What’s Nearby

Wi-Fi Direct includes two things potentially useful: discovery Wi-Fi device and direct the Discovery Service. The device not only knows that there are devices available, the device can also know what kind of devices are nearby and what is on offer. For example, if you are trying to view an image, you will only see the devices you can send images, if you want to print, you will only see the devices that are or that are connected to printers. Fundamentally this can happen before you connect, so you don’t waste time trying to connect with something that does what you want it to do.

Wi-Fi Direct Uses the Same Chip Wi-Fi

The manufacturers do not need to add radios extras to your kit: the idea is to have Wi-Fi Direct, as part of the chip and the Wi-Fi standard. It is also compatible with old models also, so you do not need to throw out your old kit Wi-Fi.

Wi-Fi Direct is Part of DLNA, and Android Too

The Digital Living Network Alliance (DLNA) announced that it was including Wi-Fi Direct in its guidelines of interoperability, and Google has added support for Wi-Fi Direct on Android 4.0 Ice Cream Sandwich.

How Does It Work?

It’s simple: just have a mobile phone that has the Wi-Fi direct, turn on the option in the instrument menu and you will be ready to connect!
