IEEE 802.11ad-2012 was published in December 2012 and products based on this technology are now commercially available.
802.11ad uses RF burst transmissions that start with a synchronization preamble which is common to all modes, followed by header and payload data. The preamble is always single carrier modulation, the header and data may use single-carrier (SC) or OFDM modulation depending on the target bit rate.
