Wi-Fi standards have brought us the wireless networks that we are able to enjoy today. The current standard of 802.11ac has brought us the faster 5 GHz speeds, first introduced in the 802.11n standard. However, the next step to Wi-Fi, 802.11ad, while released in 2016, has been hampered by a lack of devices, particularly on the client side. 802.11ad brings the 60 GHz frequency with its significantly faster speeds, but with the trade off of short range into the wireless fold. Apart from the 60 GHz frequency, 802.11ad is essentially the same as the 802.11ac standard.
