[Answer] 802.11n uses MIMO. How does this optimize throughput to achieve the high-speed advantage that 802.11n provides?

Answer: Multiple frames are sent by several antennas over different paths and are then recombined by another set of antennas.

IEEE 802.11n -2009 or 802.11n is a wireless-networking standard that uses multiple antennas to increase data rates. The Wi-Fi Alliance has also retroactively labelled the technology for the standard as Wi-Fi 4. It standardized support for multiple-input multiple-output frame aggregation and security improvements among other features and can be used in the 2.4 GHz or 5 GHz frequency bands.

Sun Mar 20 2005 13:30:00 GMT-0500 (Eastern Standard Time) · In radio multiple-input and multiple-output or MIMO (/ ˈ m aɪ m oʊ ˈ m iː m oʊ /) is a method for multiplying the capacity of a radio link using multiple transmission and receiving antennas to exploit multipath propagation. MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi) IEEE 802.11ac (Wi-Fi) HSPA+ (3G) WiMAX and Long …

MIMO -OFDM is the foundation for most advanced wireless local area network (wireless LAN) and mobile broadband network standards because it achieves the greatest spectral efficiency and therefore delivers the highest capacity and data throughput . Greg Raleigh invented MIMO in 1996 when he showed that different data streams could be transmitted …

Mon May 14 2001 14:30:00 GMT-0400 (Eastern Daylight Time) · IEEE 802.11ac-2013 is an amendment to IEEE 802.11 published in December 2013 that builds on 802.11n . The 802.11ac standard was retroactively labelled as Wi-Fi 5 by Wi-Fi Alliance. Changes compared to 802.11n include wider channels (80 or 160 MHz versus 40 MHz) in the 5 GHz band more spatial streams (up to eight versus four) higher-order modulation (up to 256-QAM vs. 64 …
