Abstract
High definition (HD) video may be sent from, e.g., a laptop computer on a table in a room to a video projector mounted on the ceiling using a 60 GHz high capacity (2.5 Gbps) wireless link. At this frequency and data rate, the signal is so short range and directional that low power may be used and the video may be transmitted in an uncompressed form such that so much data is transmitted each second that bootlegging the content is essentially untenable. No wiring between the HD video source and the HD video display is necessary.
