The other day it was reported that the organization is Wi-Fi Alliance started certifying devices supporting the specification Wi-Fi Direct.
As it turned out, Samsung Galaxy S has already managed to successfully pass the certification. Thus, this smartphone was the first commercially available in the market and we've received support for Wi-Fi Direct.
It is worth noting that no special hardware requirements for Wi-Fi module for its compatibility with Wi-Fi Direct no. Thus, in the future, this feature can be implemented in other devices via a software update.
Wi-Fi Direct provides a direct connection via Wi-Fi between two devices without the need for a separate router. In this case, the channel is protected by the protocol WPA2. In fact, new technology is a functional analogue of Bluetooth.
With the widespread proliferation of devices that support Wi-Fi Direct rarer will require a wired connection for data exchange between PCs, printers, portable gadgets and other products.
And if the possibility of software updates to implement the new functions, it's time may come fairly quickly.
