MIMO optimizes throughput to gain the high$-$speed advantage that $802\mathrm{.}11n$ provides. Which of the following statements is true in relation to the given information? A $0$ Several frames are sent by several antennas over several paths, and the frames are then recombined by another set of antennas. B $0$ Only one frame is sent at a time, but it is faster than $802\mathrm{.}11g$ because multiple antennas are used $($multiple$-$in$,$ multiple$-$out$).$ C MIMO packs smaller packets into a single unit, which improves throughput. MIMO specifies an acknowledgment of each and every frame, whereas $802\mathrm{.}11n$ provides better overhead.
