What to Expect from 802.11ac

The extensions of the physical-layer wireless techniques pioneered in 802.11n which make up the final 802.11ac Wi-Fi standard will have a considerable impact on enterprise wireless LANs (WLANs).

Use of multiple antennas will give increases in the amount of wireless bandwidth in a cell, improving throughput and giving crucial capability in environments that serve high densities of Wi-Fi clients, such as stadia and other large public venues. This trend will also vastly improve the reliability of Wi-Fi connections, making it easier to provide Wi-Fi coverage around physical obstructions like elevator shafts and stair wells.

The IEEE 802.11ac standard takes many of the best techniques the Wi-Fi industry has learned about 802.11n, and makes extraordinary improvements upon them. In enterprise networks, the higher rates and increased capacity of 802.11ac will break down the last remaining barriers to the all-wireless office.
