On "High-frequency signals diffuse quickly, which means an optimized 60 GHz network would require a lot of chips spread around a room and tightly focused antennas."

Typically modern wireless devices use multiple transceivers (single chip but multiple antennas) to mitigate multi-path problems. These relate to problems because of wireless waves bouncing off from different surfaces before reaching the intended receiver. One solution is to use multiple transceivers to beamform or steer the waves. So the use of multiple transceivers is not related to the conventional repeater/relay concept. In home entertainment scenario, each transmitter(STB)/receiver(TV) will have one chip and set of antennas and thats all.

I know there is a company called SiBeam who have also announced a CMOS based solution for 60 GHz.

Yeah, I think you’re right. If you are just sending video from your cable box (or DVD player or whatever), then there’s going to be power there, and then receive the video at the TV, where there’s also power, then it shouldn’t be a problem. Let me know what you find out about them.

Dan, Vubiq looks interesting. They say they have both SiGe and CMOS technology, so I’ll check them out. As to multiple chips, the idea is one needs multiple transceivers spread around the room to keep boosting the 60GHz signal, which degrades fairly quickly. Using a single transmitter and receiver would be possible, but sucks up more power. If both devices are plugged into a wall, I suppose it wouldn’t matter.

Some company called Vubiq just issued a press release about a new 60 GHz radio that they are selling now, and they talk about wireless HD video. (link)

I don’t see why you would need more than one transmitter and one receiver, even at 60 GHz, if you’re only sending video across the room.

Transmitting large amounts of data over short distances does not equal downloading. You still have to get that multi-GB movie from a server to your house, and that will take a lot longer than one minute. The wireless HD standard is really meant for connecting your plasma TV to a DVR or set-top box without running wires through the walls.
