MOT-Phiar have gone public about their intentions in the 60GHz
realm, although the WirelessHD alliance has hardware they
are showing. that's spearheaded by SiBeam who has working 60GHz
chips done in CMOS. it's very cool - they do active beam forming
and "active tracking". the magic is not just a chip but a
chip-on-carrier with the antennas on the carrier. the two
endpoints of the 60GHz link literally find each other and
lock-on, so if somebody walks into the path and stands there,
it can switch to an alternate path using a "bank shot". as
you can imagine, there's more to this than just the RF stuff;
there are spring-heads involved.  but essentially an HDMI cable
goes in and an HDMI cable comes out. presto mesto, no men left
on base. very very cool stuff.

they are an NEA portfolio company and now that they've started
talking about their stuff, i hope i can do a presentation at
a club meeting about it.

the interesting thing about MOT-Phiar is that they are
serious about THz waves. although they certainly
are not alone in wanting to do that cheaply.
