Intel aims to unify efforts at 60GHz

Intel Corp. researchers are working on a new approach to gigabit-class wireless networks that aims to unify existing efforts at 60 GHz. In an effort to engage the industry on the concept, Intel Research will host an open workshop on the topic in October.

The effort comes at a time when two groups in the IEEE are clashing over the future of 60 GHz. The 802.15.3c group is developing an early draft of a specification aimed at point-to-point links for wireless displays and kiosks. A separate 802.11 study group wants to use 60 GHz to deliver aGbps version of WiFi.

"We really believe in a single interoperable solution, but many efforts are focused on point solutions," said Lilly Yang, an Intel researcher speaking at the Intel Developer Forum Tuesday (Aug. 19).

Yang sketched out some of Intel's work on a solution that could deliver more than 4Gbps over 60 GHz for applications ranging from wireless displays to future WiFi networks. The approach would need to embrace uses that span one to ten meters, some requiring line of sight links and others not needed it.

"We are talking about a diverse set of requirements for a diverse set of platforms," Yang said. "We want one interoperable solution to support all these uses," she said.

She described some of Intel's work on a media access controller that could handle sector sweeping and antenna training and tracking for device discovery. It would also employ spatial frequency reuse.

"We need to design almost every aspect of a MAC to make it efficient," she said.

The Intel workshop will be held October 6-7 at Intel Research in Hillsboro, Oregon.
