wigigWiGig Alliance Announces Completion of its Multi‐Gigabit Wireless Specification

Four members join alliance, including leaders in PC display market, adding breadth to diverse, multi‐industry membership

Wireless Gigabit Alliance (WiGig), the organization advancing the adoption and widespread use of 60 GHz wireless technology worldwide, today announced the completion of its unified wireless specification. The WiGig specification enables high performance wireless display and audio and provides data transfer rates more than 10 times faster than today’s wireless LANs, extending Wi‐Fi technology while supporting backward compatibility with existing Wi‐Fi devices. The completed specification is now ready for member review and is anticipated to be made available to WiGig adopter members in Q1 2010.

“When we launched the WiGig Alliance in May, we announced our plan to complete the industry’s first unified 60 GHz specification by Q4 2009, and we are proud to deliver on this promise to the industry,” said Dr. Ali Sadri, president and chairman of the Wireless Gigabit Alliance. “We’re rapidly paving the way for the introduction of the next generation of high‐performance wireless products – PCs, mobile handsets, TVs and displays, Blu‐ray disc players, digital cameras and many more.”

Specification Highlights

The WiGig version 1.0 specification includes the following key elements:

Supports data transmission rates up to 7 Gbps – more than ten times faster than the highest 802.11n rate
Supplements and extends the 802.11 Medium Access Control (MAC) layer and is backward compatible with the IEEE 802.11 standard
Physical layer enables both the low power and the high performance WiGig devices, guaranteeing interoperability and communication at gigabit rates
Protocol adaptation layers are being developed to support specific system interfaces including data buses for PC peripherals and display interfaces for HDTVs, monitors and projectors
Support for beamforming, enabling robust communication at distances beyond 10 meters
Widely used advanced security and power management for WiGig devices
“WiGig has reached a milestone with the completion of its specification as promised by year end, demonstrating the organization’s commitment to deliver,” said Craig Mathias, a Principal with the wireless and mobile advisory firm Farpoint Group. “By complementing Wi-Fi and enabling multi-gigabit speeds, the versatile specification is a very significant achievement on the road to the next generation of wireless LAN products.”

New Members Join WiGig Alliance

WiGig Alliance has experienced steady growth with four new members joining in Q4, with total membership approaching 30 industry‐leading companies. NVIDIA has joined the organization’s board of directors, and AMD, SK Telecom and TMC have joined as contributor members. Semiconductor industry pillars NVIDIA and AMD boost the organization’s support for PC wireless display applications. SK Telecom, the largest South Korean telecommunications company, and TMC, an independent testing and certification lab headquartered in China, add depth and bring additional expertise to the organization.

“NVIDIA recognizes the general market trend toward wire‐free interfaces. Today, display interfaces are at an inflection point where the next generation solutions will feature wireless display connections for PCs, game consoles, notebooks and mobile devices with PC monitors and TVs,” said Devang Sachdev, Technology Marketing Manager at NVIDIA and WiGig Board Member. “NVIDIA supports open standards for wireless transmission of data for display and interfaces such as PCIe, USB, etc., and we see this as aligned with WiGig’s work.”

“We are extremely proud that the extent of our membership includes world leaders from the consumer electronics, mobile and PC segments. This diversity of representation and participation is enabling WiGig to deliver innovative wireless solutions that will meet market demand in a timely manner,” said Sadri.

WiGig Alliance Makes Push for HD Specification

Jul 29

Posted by andrew in News | No Comments

The Wireless Gigabit Alliance (WiGig), an organization formed in May to develop an industry specification for high-definition wireless data sent over the 60-GHz band, is on a mission to create “wireless homes” and eliminate the need for HDMI (High-Definition Multimedia Interface) cables. The technology is progressing quickly and a specification is targeted for late this year, making WiGig’s vision only a few months away from reality. “[We] envision a global wireless ecosystem of extremely high performance consumer electronics, handheld devices, and personal computers that work together seamlessly to connect people to the information and content that matters to them,” said Mark Grodzinsky, the WiGig marketing chair.

WiGig, however, is a late entry among several groups working toward an uncompressed wireless solution for high-definition content. The Wireless Home Digital Interface (WHDI) is in development as the next step for high-definition television and other displays, although it will operate in the more constricted 5-GHz band. Operating in the same 60-GHz space as WiGig is Wireless HD, a specification that came out in January 2008 and has already been implemented in some devices.

Both WiGig and Wireless HD offer high-speed transfer rates at greater than 1 Gbyte per second, connecting a multitude of devices, including game consoles, cameras, and mobile phones, in a single room. Reports about WiGig’s arrival were quick to call it a Wireless HD competitor. However, insiders with both organizations don’t see it that way. Instead, they say the two technologies will eventually work side by side, offering similar but different functions.

“The industry wants a gigabit-speed technology that can be used across multiple applications on many different platforms,” Grodzinsky said in an e-mail. “The WiGig specification achieves this goal, and has the support of major players from each of these segments, to ensure we keep to our mission.”

Grodzinsky sees the industry as a whole looking for a broader solution set, but he also sees “a set of consumer electronics customers that will only require the wireless HDMI functionality that WiHD provides. Therefore, we do not expect that WiGig and WiHD will be competing for sockets, but rather will both serve their customers side by side in the marketplace.”

John Marshall, chair of the Wireless HD consortium, noted that his technology already has plenty of momentum in the 60-GHz space. The group is currently developing its next-generation specification, version 1.1, and nearly 60 companies have signed up as promoters and adopters. Chipset maker SiBeam is driving much of the development.

Some of the adopters, such as Toshiba and Samsung, have signed up for both WiGig and Wireless HD, and Marshall says the situation indicates how the industry sees the future of wireless. “I think that the promoters of WiGig and the promoters of Wireless HD don’t see a competitive dynamic,” he said.

The Wireless HD consortium also has a coexistence subcommittee to ensure that there is no interference with the technologies, a problem that has appeared often in WiFi.

“Really, what you’re looking at with WiGig is very high speed data sync. What you’re looking at with Wireless HD is a wireless communication platform for audio-video data entertainment with multimedia,” Marshall said. “Take for example a phone. If you’ve got data that I want to move back and forth on that phone, you’re going to consider a WiGig solution. If you’re going to consider whether that phone is a mutimedia device, then you’re going to think of a Wireless HD solution. With WiGig you’re going to move data very fast. With Wireless HD, you can move data fast but you can also stream it to a TV.”

Another factor that must be considered for WiGig to move forward is the IEEE standards committee, which currently has a working group for 802.11ad in the 60-GHz band. According to Grodzinsky, the WiGig Alliance plans to contribute to the standard, which isn’t expected to arrive until at least 2012.
