WIFI keeps on advancing and keeps getting faster. The first revision of IEEE 802.11ay has just been defined by IEEE. They are targeting 176 Gb/s. Not really needed for fast internet or file transfers, but think more along the lines of wireless displays.
802.11ay is a type of WLAN in the IEEE 802.11 set of WLANs. It will have a frequency of 60 GHz, a transmission rate of 20–40 Gbit/s and an extended transmission distance of 300–500 meters. It has also been noted that it is likely to have mechanisms for channel bonding and MU-MIMO technologies. It is expected to be released in 2017. 802.11ay will not be a new type of WLAN in the IEEE 802.11 set, but will simply be an improvement on 802.11ad.
Where 802.11ad uses a maximum of 2.16 GHz bandwidth, 802.11ay bonds four of those channels together for a maximum bandwidth of 8.64 GHz. MIMO is also added with a maximum of 4 streams. The link-rate per stream is 44Gb/s, with four streams this goes up to 176Gb/s. Higher order modulation is also added, probably up to 256-QAM.
Draft version 0.1 of 802.11ay was released in January 2017. Draft version 0.2 will be following in March 2017 and draft version 1.0 is expected to be available in July 2017.
