7 Gbps Wi-Fi specification
Wireless Gigabit Alliance (WiGig) recently 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.”
