WiGig And VESA Form Working Group

Nov. 28, 2012
A working group is now taking strides to make sure that future WiGig devices are compatible with DisplayPort, which is one of the most widely established display connection technologies for PCs.

Together, the Wireless Gigabit Alliance (WiGig) and the Video Electronics Standards Association (VESA) have established a joint working group to advance WiGig DisplayPort video standard certification. This partnership will address interoperability between the DisplayPort standard and WiGig’s Display Extension Protocol Adaption Layer (PAL). When the group’s work is complete, DisplayPort-certified WiGig devices will seamlessly interconnect without wires. Thus, a DisplayPort interface will be able to be used without the use of a DisplayPort cable.

The WiGig Alliance has developed 60-GHz multigigabit wireless standards, which can transmit at speeds to 7 Gb/s. For its part, VESA created, owns, and certifies the digital display interface, DisplayPort, which is mainly used to connect a video source to a display device. According to IDC, DisplayPort will be featured in 89.5% of commercial desktops and 95% of commercial notebooks by 2014. With a wireless extension added to DisplayPort, users will gain a better experience while the protocol itself will be enhanced.

WiGig Alliance published its Display PAL, known as WiGig Display Extension (WDE), in 2011. The specification was developed to support PC peripherals, HDTVs, monitors, and projectors. It also supports the latest High-bandwidth Digital Content Protection (HDCP) encryption and is capable of the transmission of both compressed and uncompressed video.
