CES 2010

Among the four or five contenders showing wireless HD transmission systems is the WirelessHD Consortium, which includes 30 companies such as LG, Panasonic, Samsung, Sony, and Toshiba. The system transmits up to 1080p/60 in the 60GHz range, which is relatively free from interference, and it has a maximum latency of 1-2ms. RF signals at this frequency can be blocked by obstacles such as people, so the technology automatically redirects the beam to reflect off walls, ceiling, or floor as needed, and it's designed to transmit its full bandwidth up to 10 meters as long as there's some line-of-sight path to be found. Pictured here is a WirelessHD transmitter (bottom) and receiver (top) by LG Innotek, a subsidiary of LG that makes components for various products from LG and other manufacturers.
