WirelessHD, also known as UltraGig, [1] is a proprietary standard owned by Silicon Image (originally SiBeam) for wireless transmission of high-definition video content for consumer electronics products.
WHDI 1.0 provides a high-quality, uncompressed wireless link which supports data rates of up to 3 Gbit/s (allowing 1920×1080 @ 60 Hz @ 24-bit) in a 40 MHz channel, and data rates of up to 1.5 Gbit/s (allowing 1280×720 @ 60 Hz @ 24-bit or 1920×1080 @ 30 Hz @ 24-bit) in a single 20 MHz channel of the 5 GHz unlicensed band, conforming to FCC and worldwide 5 GHz spectrum regulations.
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable , allowing users to transmit signals wirelessly between the component device and the display device.
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual media. [1] Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems, which, in turn, were replaced by flat-panel displays of several types.

High-definition video (HD video) is video of higher resolution and quality than standard-definition. While there is no standardized meaning for high-definition , generally any video image with considerably more than 480 vertical scan lines (North America) or 576 vertical lines (Europe) is considered high-definition.
Analogue video senders have the advantage of low manufacturing costs as the audio and video signals are simply modulated onto a carrier at 2.4 GHz or 5.8 GHz.They do, however, have the adverse effect of causing reduced bandwidth to local Wi-Fi networks and, in some cases, Wi-Fi networks can cause picture interference on the video sender signal.
