160 MHz

Explanation:
Detailed explanation-1: -For example, we can calculate the maximum theoretical speed that the 802.11ac standard can provide. On a single spatial stream, with a channel width of 160 MHz and 256-QAM modulation, the maximum theoretical speed is 867 Mbps. The 802.11ac standard optionally* supports 8 spatial streams.
Detailed explanation-2: -MIMO – (Multiple Input/Multiple Output) Unlike traditional/old 802.11a/b/g radios, which use single-input and single-output (SISO), 802.11n and 802.11ac radios use MIMO technology to increase throughput by increasing the number of radio transmit and receive chains (antennas or a group of antennas).
