The world is abandoning the cables, but the Wi-Fi or Bluetooth 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 messing with access points and long passphrases? That’s what promises the Wi-Fi Direct.
Wi-Fi Direct is A Suitable Pattern
He came up through the Wi-Fi Alliance, the global industry association responsible for certifying Wi-Fi kits.
Wi-Fi Direct is Wi-Fi, Without the Part of the Internet
The idea behind Wi-Fi direct is that simple tasks need simple connections. For example, you may want to print from your laptop or smartphone into 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 to the printer, hardware of the other person or with the TV. With the Wi-Fi Direct, is easier and faster too.
Wi-Fi Direct Can Be Part of the Internet Also
If you have a Wi-Fi router connected to the internet, you can connect the network also.
Wi-Fi Direct Doesn’t Need A Wireless Access Point
Wi-Fi Direct devices can connect to each other without having to go through an access point: can establish ad-hoc networks when required, allowing you to see which devices are available and choose which one you want to connect. If that sounds a lot like Bluetooth, it’s because it is.
Wi-Fi Direct Uses Wi-Fi Protection Configuration
You don’t want anyone to be able to connect to your hardware. for example, you may not want to see what the neighbors are on TV in your TV. So Wi-Fi Direct uses Wi-Fi Protected Setup and WPA2 to prevent unauthorized connections and keep your communications private. There are two ways to establish a connection: with physical buttons (press the button on the 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 potentially useful things: Wi-Fi device discovery and Discovery Service. The device not only knows that there are devices available, the device can also know what kind of devices are close by and what is on offer. For example, if you are trying to display an image, you will only see the devices that you can send pictures, if you want to print, you’ll only see the devices that are or that are connected to printers. Basically 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
Manufacturers do not need to add extra radios for your kit: the idea is to have Wi-Fi Direct, as part of standard Wi-Fi chip. It is also compatible with older models too, so you don’t have to throw away your old Wi-Fi kit.
Wi-Fi Direct is Part Of DLNA and Android Also
The Digital Living Network Alliance (DLNA) announced it was including Wi-Fi Direct in its interoperability guidelines and Google added support for Wi-Fi Direct on Android 4.0 Ice Cream Sandwich.
How Does It Work?
It’s simple: just having a cell phone that has Wi-Fi direct, call the option in the menu and you will be ready to connect!
