How Miracast enables wireless projection?

As wireless media sharing becomes increasingly popular, Miracast is poised for mass adoption.

If you are attending a conference and want to share files from your smartphone. Ideally, you want to play the files through the HDTV in your room. Do you need to plug in a cable or transfer photos to an SD card or USB flash drive before uploading them to your TV?

No! Miracast, the Miracast protocol for our Android phones, allows you to share smartphone screen images, videos and photos directly to your TV over WIFI, without the need for cumbersome cables or storage devices.
