Can it Wi-Fi 6 is being prepared, but it will not offer the fastest wireless connection. WiGig, on the contrary, is designed for extremely fast speeds over short distances and an improved version is preparing to release 2019.
WiGig transmits data wirelessly at 60 GHz, as opposed to Wi-Fi 6 and other "normal" versions of Wi-Fi that use 2.4 or 5GHz frequencies.
The frequency of 60GHz is less used than 2.4GHz and 5GHz, which means it can transfer more data at a time. This translates into faster wireless data transfer speeds. In short, you have faster Wi-Fi when using WiGig.
The current version of WiGig is giving speeds around 5 Gbps, while the actual speeds of Wi-Fi 6 will probably be slightly more than 2 Gbps. The latest version of WiGig should be even faster at about 10 Gbps.
It sounds good, but there is a disadvantage. The shorter wavelengths used by WiGig give it much less bandwidth. The Wi-Fi Alliance reports that the current version of WiGig can support distances up to 10 meters. However, the WiGig brand will have difficulty passing through walls or other obstacles.
WiGig devices can drop to frequencies of 2,4 GHz or 5 GHz if necessary, but at these frequencies, they do not give WiGig ultra-fast speeds.
WiGig was first announced by 2009 by Wireless Gigabit Alliance, a trade association that supports this technology. In 2013, the Wireless Gigabit Alliance shut down and took over the Wi-Fi Alliance that oversees Wi-Fi standards such as Wi-Fi 6. Thus, "Wi-Fi CERTIFIED WiGig" is now a standard of the Wi-Fi Alliance.
The original version of WiGig, released by 2012, uses the 802.11ad standard and offers speeds around 5Gbps at a maximum distance of 10 meters.
The new, faster model called 802.11ay is scheduled to release 2019, so we will see faster WiGig products. Qualcomm's Dino Bekis told The Verge that this new standard may be twice as fast and that it will communicate at distances up to 100 meters.
WiGig will not replace Wi-Fi 6 as it will not be able to go through walls and other obstacles.
You can think of WiGig as an optional Wi-Fi add-on. Any devices that support WiGig will also support basic templates such as WI-Fi 6. But it will include all Wi-Fi 6 devices, WiGig support.
The oldest 802.11ad was released for a while, and the devices that support it are very few. Devices that support 802.11ay will begin running 2019.
For example, if you buy an ASUS ROG phone, its base communicates with its adapter via WiGig.
Theoretically, you could buy a WiGig-enabled router and a WiGig-enabled laptop and have extremely fast speeds, but these devices have not yet appeared on the market.
