The 802.11ac standard supports higher data rates, improved capacity, and better performance in dense environments. It offers significant improvements over previous standards like 802.11a,
802.11b, 802.11g, and 802.11n, with support for speeds up to several gigabits per second under optimal conditions. For a range of 115ft indoors and a speed of 700Mbps, 802.11ac is the most suitable choice due to its enhanced capabilities to handle higher speeds and greater ranges than its predecessors.
