 These include technologies that allow for mobile device screen-mirroring, such as Miracast and Airplay, as well as media streaming features such as DLNA.Ultra-wideband is a technology for transmitting information spread over a large bandwidth (>500 MHz) and is generally used for short-range applications (typically 10 metres or less) where a simple link is required from the source device to a monitor or television.As such, it is generally unsuitable for video sender applications that would require a signal to be sent to another room.
