WiGig is a wireless connection standard that also operates under the 802.11ad moniker. It’s also informally known as Wireless AD. WiGig’s name stems from its origins with the Wireless Gigabit Alliance, a trade alliance that was subsumed by the aforementioned Wi-Fi Alliance in 2013.

WiGig acts as a complement to existing Wi-Fi rather than a replacement for it, and provides extremely fast, low-latency wireless internet connectivity under certain circumstances.
How does it work?

While current Wi-Fi uses the crowded 2.4GHz and 5GHz frequency bands, WiGig uses the relatively unused 60GHz spectrum. This enables it to use wider channels than standard Wi-Fi, resulting in significantly faster data rates of up to 8 Gbps.

WiGig uses beamforming technology to send a finely directed signal between devices at a distance of up to 10 metres. This focused broadcast serves to eliminate any interference from nearby devices, as well as to maintain high performance even in areas where the 60 GHz spectrum might be in heavy use.

Multi-band Wi-Fi Certified products are able to smartly and seamlessly switch between 2.4, 5, and 60 GHz frequencies on the fly, according to the connectivity environment.
