Wi-Fi Direct enables mobile phones, cameras, printers, PCs, and gaming devices to create their own Wi-Fi networks without an internet connection. Connect other Wi-Fi Direct devices to each other to transfer or display content, play games, and share applications quickly and easily through device settings. Devices can make a one-to-one connection, or a group of several devices can connect simultaneously. Because there is no need for an access point or internet connection, Wi-Fi Direct networks go wherever devices go.
Thousands of devices such as smartphones, cameras, printers, televisions, PCs, and gaming devices are already certified. Wi-Fi Direct devices can connect anywhere, anytime—even when there is no access to a Wi-Fi network nearby. Wi-Fi Direct devices emit a signal to other devices in the area, letting them know a connection can be made.
Users can view available devices and request a connection or may receive an invitation to connect to another device. Compatibility and quality are achieved through testing of Wi-Fi products. It simply requires the push of a button or the entry of a PIN. Wi-Fi Direct allows source and display devices to discover one another and provides the underlying device-to-device connectivity for Miracast.
Miracast builds upon Wi-Fi Direct with mechanisms to negotiate video capabilities, setup content protection if needed , stream content, and maintain the video session. Wi-Fi Direct devices work just like any Wi-Fi device, with ranges up to meters. They can connect from just a few feet away, but also across a home.
Even at lower speeds, Wi-Fi provides plenty of throughput for transferring multimedia content with ease.
The performance of a particular group of Wi-Fi Direct devices depends on whether the devices are A single device in a Wi-Fi Direct-certified group network may share internet connectivity with other devices in the network by creating simultaneous infrastructure and Wi-Fi Direct connections. A network of devices certified under the Wi-Fi Direct program operates in a security domain separate from the infrastructure network, even when cross-connected.
A Wi-Fi Direct-certified network can be one-to-one, or one-to-many. Connection to multiple other devices is an optional feature that will not be supported in all Wi-Fi Direct devices; some devices will only make connections. On IEEE It may take some time to find and connect to a wireless LAN access point before starting communications via the wireless LAN. Once you connect your VAIO computer to the access point by entering the security key, the access point will be registered in the computer.
You do not have to enter the security key for subsequent connections. Before using the wireless LAN, make sure your access point is on and operating. If it is set to Off , click it to toggle to On.
