Wi-Fi CERTIFIED Wi-Fi Direct

What exactly is Wi-Fi CERTIFIED Wi-Fi Direct?

Wi-Fi CERTIFIED Wi-Fi Direct is an upcoming certification program from the Wi-Fi Alliance® that defines a new way for Wi-Fi devices to connect to each other directly.
Wi-Fi Direct is an emerging technology meant to meet the growing demand for easy, portable wireless network connectivity.
It's peer-to-peer wireless networking, which means that wireless devices such as notebooks,
Mobile phones, PC, printers etc. can "find" one another and establish wireless connectivity
without need of the presence of a wireless router, an access point, or wifi hotspots.

Wireless devices can now connect to each other directly
to transfer content and share applications quickly and easily.
Devices can make a one-to-one connection, or a group of several devices can connect simultaneously.

Connections based on the specification will work at typical Wi-Fi speeds and range, protected by WPA2. So the most significant difference between traditional ad-hoc wireless networking (traditional peer-to-peer networking) and Wi-Fi Direct is security,speed and range.
Typical Wi-Fi speeds, which can be as high as 250 Mbps, ranges up to 200 meters.
They can connect from just a few feet away, but also across a home.

Wi-Fi Direct devices near one another can transfer content at speeds 25 times faster than they could with Bluetooth 2.0.So this wifi technology should totally replace Bluetooth technology.

By the way, only Wi-Fi Alliance member companies will be able to use the Wi-Fi Direct mark to indicate that their products implement this specification.
