NEWS: CE giants pitch yet another wireless HD standard
John Navas
Just what the world needs: another consortium promoting a wireless
technology for the transmission of HD content in the home.
The latest is the Wireless Home Digital Interface (WHDI), launched
today by Sony, Samsung, Hitachi, Motorola and Sharp.
WHDI's technology comes from Israeli company Amimon. It uses the 5GHz
band to transmit uncompressed 1080p video, audio and control signals
around the home from multiple sources to multiple receivers. All this
data is beamed at up to 3Gb/s.
Amimon claimed WHDI's range is 30.5m. It can go through walls and has
a latency of less than a millisecond.

Now where, oh where, do you suppose they came
up with that wierd figure of "30.5 meters"?
You don't suppose they've converted from
a nice round number in some other measuring
system, doyathink?

Standards are a good thing. Every company (and consortium) should
have one.

They paced it off. 1 pace = 1 meter. When they ran a little short,
they got out the tape measure, and added the extra 0.5 meter.

Nope. It's suppose to go through walls. They probably paced it off
until they hit a wall, walked around to the other side, and continued
pacing.
Another possibility is that they used one of those ultrasonic
measuring tapes. They read off in tenths of a meter.
Yet another possibility is that they couldn't decide if they should
round the 0.5 up or down.
Of course, the article didn't mention if it was actually usable at
30.5 meters, or whether the error rate was sufficient to irritate the
avearge TV user. Most users can tolerate quite a bit of garbled audio
(i.e. cell phones, VoIP), but even a few artifacts on the HDTV screen
will produce an irate phone call to the cable or satellite providers
outsourced support provider.

While being bored on a pointless training course I also came across an
article about "iMAT" which purports to give MIMO capability with a
single antenna and has been tried in a WIMAX USB device.
