802.11ay Training, IEEE 802.11ay: Next-generation 60 GHz Communication for 100 Gbps Wi-Fi

802.11ay Training covers the design elements of 802.11ay standard, Wi-Fi communications in unlicensed mm-Wave bands, providing 100 Gb/s to support  new applications such as VR/AR (virtual reality/augmented reality), and wireless backhauling.

The 802.11ay PHY and MAC are built upon IEEE 802.11ad with main design elements of IEEE 802.11ay include MIMO, channel bonding, improved channel access, and enhanced beamforming training. 802.11ay is the next-generation Wi-Fi standard for the 60 GHz band.

IEEE 802.11ad supports transmission rates of up to 8 Gbps using single-input-single-output (SISO) wireless transmissions over a single 2.16 GHz channel, while IEEE 802.11ay, increases the peak data rate to 100 Gbps by supporting multiple independent data streams and higher channel bandwidth, backward compatibility and coexistence with Directional Multi-Gigabit (DMG) stations (STAs). DMG refers to IEEE 802.11ad and Enhanced DMG (EDMG) refers to devices that can support features of and IEEE 802.11ay standards.
