Wi-Fi Display, new technology that allows you to connect different devices without cables

Qualcomm has developed the first generation of the Wi-Fi Display standard, a technology that allows multimedia content played on the screen of one device to be sent to another device instantly through a direct wireless connection (P2P).

At the last edition of the CES fair in Las Vegas, Qualcomm exhibited its Wi-Fi Display technology, that allows connection between devices with direct Wi-Fi signals. That is to say, that does not require the existence of a common Wi-Fi network to which both must connect. Thus, This type of connection can be made in a simple way at any time and place with the only requirement that both devices are compatible with this technology.

It is not about transferring files between devices. Instead of this, Wi-Fi Display captures the source device's screen and sends it as a high-definition video (1080p, H.264 encoding) to the destination device, where it is displayed at the corresponding screen size automatically.

Although it is a direct connection between devices, the radio signal is protected with the WPA2 Wi-Fi security mechanism., so it can only be decoded at the authorized receiver during the initial binding process.

Applicable to numerous devices
Qualcomm promises that the Wi-Fi Display standard will be available this year so that it can begin to be implemented on mobile devices with Snapdragon S4 processors. The technology that will be in charge of promoting it will be Qualcomm Atheros.

It could also be seen on Windows Phone phones and later on the rest of the devices that can take advantage of it.: digital video players and recorders, projectors, televisions, tablets and mobiles, inter alia. Wi-Fi Display can even be enabled on current devices with an HDMI connection through a relatively simple and cheap accessory.
