Question

Which of the following is used by IEEE 802.11n to achieve high throughput through the use of multiple antennas for transmission and reception?

A) MIMO (Multiple Input Multiple Output)
B) OFDM (Orthogonal Frequency Division Multiplexing)
C) DSSS (Direct Sequence Spread Spectrum)
D) FHSS (Frequency Hopping Spread Spectrum)

Answer 1

IEEE 802.11n uses MIMO (Multiple Input Multiple Output) to achieve high throughput by utilizing multiple antennas for simultaneous data transmission and reception.

Step-by-step explanation:

The technology used by IEEE 802.11n to achieve high throughput through the use of multiple antennas for transmission and reception is A) MIMO (Multiple Input Multiple Output). MIMO technology allows for the simultaneous transmission and reception of multiple data signals over the same radio channel by using multiple antennas. This leads to increased data rates and improved reliability.

MIMO works alongside OFDM (Orthogonal Frequency Division Multiplexing), which is another method that contributes to high throughput in wireless communication by dividing the radio signal into several sub-signals before they reach the receiver. This helps to reduce interference and improve the signal quality. However, the specific technology that enables the use of multiple antennas is MIMO.
