One step forward, two steps back seemed to be part of the theme for wireless. 10G 802.11AC was ratified some time ago. This standard created 10G capable Wi-Fi. The trick was that two Category 6A cables are required to the access point. Assuming that companies would have a hard time upgrading and installing these cables, chip manufacturers created two new standards for 2.5Gb/s and 5Gb/s chips that run over 5e and 6 cabling respectively. These are a change from moving forward with higher speeds to moving backward with more interim speed options.
