Comparison of 802.11ac and 802.11n PHY layers

802.11ac, n and ad are three newest IEEE standards. 802.11n implements a lot of new proposals especially in PHY and MAC layers while in 802.11ac there aren’t any new technologies but only optimization and development of ac new ideas. Both propose signifi cant increased in throughput but only ac reaches the level which could guarantee the multimedia successful communication. Author compares the most important features of PHY layers of both standards.
