There is no denying that Wi-Fi continues to be the mega-highway inside the home. More than 1.5 billion Wi-Fi devices were sold in 2012 alone, according to ABI Research.
that, in turn, could give rise to some legitimate concerns over
congestion and robustness with WiFi devices in the future. Silicon Image
is betting the farm (and its UltraGig) on that side of the argument.
the congestion issues, Vehling offered UltraGig’s low latency and
better video quality as advantages. “60GHz Wireless HD offers less than
5ms of latency,” said Vehling, stressing its importance for gaming
applications. Further, “due to increased bandwidth offered by 60GHz,
video quality is better,” he added. “H.264 compression is not used.”
So what’s the bottom line?
This, of course, is the classic argument over proprietary technology vs.
standardized spec. Undoubtedly, UltraGig’s drawback is that “it is a
proprietary silicon solution, and Silicon Image is the sole-source
silicon vendor,” said IHS analyst O’Rourke. “This makes it relatively
expensive and a risk for CE vendors to offer it.”
has been marketing UltraGig to OEMs for a while, “without much success
to date,” according to O’Rourke. Silicon Image is “caught in a dilemma –
they need increased volumes to drive down chip ASPs, but OEMs want
lower ASPs before committing to large-scale integration,” he explained.
silicon source for UltraGig would help, as it would reduce the supply
risk to PC or CE OEMs of offering UltraGig,” he added.
The battle between UltraGig and Miracast could also take a new, unexpected turn, however.
