in a short term, this battle is couched as a proprietary 60GHz UltraGig
vs. Miracast using a 2.4GHz or 5GHz WiFi technology.
that the WiGig Alliance (promoting an open standard based on a 60GHz
technology) and Wi-Fi Alliance recently announced that they would merge,
Cooney predicted, “WiGig will be incorporated into Wi-Fi, and 802.11ad
will become the main 60GHz standard.” WiGig or 802.11ad is an
ultra-wideband (UWB) technology that uses 800 MHz or 1,600 MHz of
spectrum in the 60 GHz band to achieve speeds up to 7 Gbps. The merger
of the two competing groups will surely blur the line between 60GHz
technology and the 2.4GHz/5GHz WiFi standards.
Noting that WiGig
is an open standard available to all members of the WiGig Alliance,
Cooney explained, “Silicon Image is a member of the WiGig Alliance. So
the company does have access to WiGig as well as UltraGig.”
course, UltraGig is already available, Silicon Image pledges to drive
initial 60GHz tech growth. That won’t alter the fact that UltraGig today
is still a proprietary technology.
But looking into the next two to three years, Cooney sees a very different future.
“will have the might of the Wi-Fi Alliance and its members behind it.
It will be fairly difficult (or impossible) to for another 60GHz
technology to compete with this,” he said.
Is he too optimistic? Maybe, maybe not.
Research’s position is that 802.11ad (WiGig) will be deployed mainly in
tri-band chipsets (i.e. 802.11n, 802.11ac, 802.11ad together) and
devices will then be able to seamlessly choose which protocol to use
depending on the situation.
Beyond Silicon Image, other vendors are working in the 60GHz space.
them, “Wilocity is the furthest down the line and was demoing their
60Ghz/WiGig/11ad solution in their private suite” at CES, Cooney noted.
Wi-Gig vendor Wilocity has partnered with both Qualcomm and Marvell to
deliver tri-band solutions. Meanwhile, Dell became the first to announce
an ultrabook with WiGig/80211ad, developed by Wilocity and Wi-Fi vendor
How this will affect the future of Silicon
Image’s UltraGig is not known. Further, whether Silicon Image will morph
its proprietary technology into a part of the WiGig solutions remains
to be seen.
But at least, for now, ABI Research seems to believe
that UltraGig won’t long stay as a proprietary 60GHz wireless
technology totally isolated from either WiGig or WiFi.
