园区网络规划与部署

To deliver higher bandwidth, 802.11ax adopts most 802.11ac technologies and introduces OFDMA to redefine modulation multiplexing in support of wider subcarrier spacing.

Explanation

802.11ax uses OFDMA to partition a channel into resource units that can be allocated to multiple users. Its subcarrier spacing is narrower than that of 802.11ac, not wider.
