When you try to connect two devices in a local wireless network, you usually have to choose between speed (Wi-Fi) or ease of connectivity (Bluetooth).
But the Wi-Fi alliance has launched Wi-Fi Direct, which combines both advantages into one technology…
Wi-Fi offers plenty of bandwidth but you need to have a wireless network set up wherever you need to connect the devices (so a router is a must).
That’s not always desirable, sometimes even impossible. Wi-Fi Direct, as the name suggests, makes a direct connection between two (or more) devices with no middleman required.
Connecting two devices would be as simple as pressing a button. All Direct communications are secured by WPA2, so the ease of connecting doesn’t mean lack of security.
Wi-Fi Direct works with 802.11b/g/n and supports both 2.4GHz and 5GHz – there won’t be a shortage of bandwidth.
Many Wi-Fi Direct devices will also be able to connect to several other devices at once – for example,
a laptop can push a video to the TV while syncing with your mobile phone, all over Direct and with no router required !!!!!
