WiGig and VESA making wireless DisplayPort tech
The WiGig Alliance and the VESA display group today said they were working together on developing a wireless DisplayPort standard. Both groups plan to share technology that would allow for "multi-gigabit" bandwidth and display quality as good as a wired DisplayPort connection over the air. The ultra wideband technology was considered good fit as the sheer headroom and architecture are good enough to both match the same quality as DisplayPort and scale to future versions.
The design could lead to more straightforward implementations such as wireless docking stations for notebooks but also to wireless DisplayPort in devices beyond just computers, such as smartphones and tablets. Computers could also output directly to TVs without having to use a platform-specific wireless format such as Intel's WiDi (Wireless Display). WiGig and VESA believed that the technology would be efficient enough to use without having too large an impact on battery life.
Development is still early and hasn't been given a timetable.
Along with DisplayPort, WiGig also noted that it had completed the specs for two key parts of its core standards. WiGig A/V will help enable wireless DisplayPort but is also intended for other formats and carries audio at the same time. WiGig I/O in turn focuses on external storage, peripherals and other common computer standards that usually need a one-to-one connection.
All of the technologies run on a 60GHz frequency and can handle as much as 7Gbps per second, or roughly 23 times the theoretical peak of most implementations of 802.11n Wi-Fi.
