Id rather keep wifi away from my gourd.
Another concern is having my brain microwaved by the signal 😄 I remember the debate a while back about mobile phones causing abnormalities being held close to the head.
So it seems the 60GHz unit is purely for transmission. The return data (headset tracking, wand tracking, state, etc) is all sent over normal wifi. Well, "normal" wifi, since apparently regular wifi routers don't work I guess.
Also at the moment the vive camera doesn't work with tpcast and the microphone wasn't supported (might be now, not sure).
Remember that 60GHz is pretty much pure line of site. The best option is to put the transmitter on the ceiling looking down, but it needs hdmi, usb and power cables running from your pc to the transmitter (on the roof). Ouch. You can also mount it on a wall, but if you turn away and bend forward (so your head goes between the tpcast receiver and transmitter) it loses the video signal.
The transmitter also makes noise. Sweviver (a youtube guy who did an unboxing of it) says it makes more noise than a lighthouse unit.
I really want wireless, but this seems very problematic for the high cost.
