requirements. For example, the 11ac PHY is based on the well known OFDM (Orthogonal Frequency Division Multiplexing) PHY used for 11a and 11n and will maintain the same modulation, interleaving and coding architecture of 11n. However, some modifications and new 11ac features/parameters are necessary to meet 11ac™s goals.
