Question

What wireless technology allows the IEEE 802.11n standard to achieve higher throughput than other standards (that is, IEEE 802.11 a/b/g) by using 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

MIMO (Multiple Input Multiple Output) technology allows the IEEE 802.11n standard to achieve higher throughput by using multiple antennas for transmission and reception.

Step-by-step explanation:

The wireless technology that allows the IEEE 802.11n standard to achieve higher throughput than other standards (IEEE 802.11 a/b/g) is MIMO (Multiple Input Multiple Output). MIMO uses multiple antennas for transmission and reception, which enables the simultaneous transmission of multiple data streams, increasing the overall data throughput.

For example, if a device has two antennas, it can transmit and receive two streams of data simultaneously, effectively doubling the data transmission rate compared to a single antenna.

By utilizing MIMO, the IEEE 802.11n standard can provide faster and more reliable wireless connections with improved coverage and speed compared to earlier standards.
