Today, the fastest Wi-FI access points use the wide bandwidth available at 60 GHz together with highly directional transmission. The next generation, termed IEEE 802.11ay, will provide an astounding 100 gigabits per second of throughput, well over 10 times what is achievable today.
Rice researchers Yasaman Ghasem Pour and Edward Knightly, together with Intel standards leaders, Carlos Cordeiro and Claudio R. C. M. da Silva have recently written a paper describing how this is achieved. The paper, “IEEE 802.11ay: Next-generation 60 GHz Communication for 100 Gbps Wi-Fi,” explores the findings of the IEEE 802.11 task group and the applications now possible with the promise of such increased throughput. The paper will be published in IEEE Communications Magazine later this year.
“Our group has collaborated with Intel for many years,” Ghasem Pour said. “Intel is part of the task group that, along with other companies, helps guide decisions on how to standardize new technology advances.”
Through their collaboration, Intel approached Ghasem Pour and asked her to write about the technological advancements being made, to update the wireless community about the key features, capabilities, and limitations of the work.
The main design elements of IEEE 802.11ay include multiple-input-multiple-output (MIMO), channel bonding, improved channel access, and enhanced beamforming training. Ghasem Pour and her co-authors discuss how each design element is impacted by millimeter wave radio propagation characteristics.
“We’ve outlined what the new standard can achieve,” she says. “The protocols and framework for commercialization show what the next generation can do. Some applications were not previously possible. As the community learns about what is now possible, we will see new applications emerging.”
The full paper, by Ghasem Pour, Knightly and Intel collaborators Claudio R. C. M. da Silva and Carlos Cordeiro will be available later this year at comsoc.org/commag and a preprint is available at Rice: http://networks.rice.edu.
