The Wireless Gigabit Alliance launched an effort to define upper layers of its software stack and completed work on three low layer software efforts.
The alliance has published two new Protocol Adaptation Layer (PAL) specifications, the WiGig Display Extension (WDE) and the WiGig Serial Extension (WSE) to supplement the previously published WiGig Bus Extension (WBE) and MAC/PHY specifications.
This accomplishment completes a successful year for the organization which has hosted the first ever interoperability test event, received ITU-R endorsement and formed a docking task group chartered with creating the first multi-gigabit wireless docking specification.
The WiGig Alliance is now calling for developer involvement in the creation of the first unified specification for multi-gigabit wireless docking. Creation and publication of the specification will enable a broad range of uses, including wireless docking and connection to displays between personal computers, consumer electronics and PC, CE, handheld devices.
The 60 GHz technology promises to deliver multiple Gbits/second of throughput. Based on the IEEE 802.11ad standard, it is scheduled for completion in late 2012. According to early tests, the first chips are delivering 3.5 to 4.5 Gbits/second user throughput, but the 60 GHz technology does not penetrate walls so is focused on in-room use.
"We have reached a major milestone this year with the completion of all the necessary components of the first ever multi-gigabit wireless docking specification," said WiGig Alliance President and Chairman, Dr. Ali Sadri. "We are now calling for industry players to participate in what will be the world?s most important short-range wireless standard and a shake up for the industry."
First release of certified WiGig products is scheduled for late 2012 or early 2013.
The group already released protocol adaption layers that provide low level support for mapping widely used wired interconnects on to WiGig including Displayport, HDMI, PCI Express and USB.
Meanwhile, products supporting another wireless technology are expected to appear next year. The 802.11ac is considered as the next iteration of Wi-Fi and delivers about 1 Gbit/s over 5 GHz. 802.11ac is being implemented in combo chips that also support .11n. |
