Question

What allows 802.11ac to have larger bandwidth usage?

1) Increased frequency range
2) Improved modulation scheme
3) Enhanced channel bonding
4) All of the above

Answer 1

802.11ac allows for larger bandwidth usage due to the combination of an increased frequency range, improved modulation scheme, and enhanced channel bonding.

Step-by-step explanation:

What allows 802.11ac to have larger bandwidth usage? The answer is 4) All of the above. This is because 802.11ac technology utilizes a combination of several improvements to provide larger bandwidth compared to its predecessors:

• Increased frequency range: 802.11ac operates exclusively in the 5 GHz band, which is less congested than the 2.4 GHz band used by older Wi-Fi standards, allowing for more non-overlapping channels and wider channel bandwidths.
• Improved modulation scheme: 802.11ac uses an advanced modulation scheme called 256-QAM (Quadrature Amplitude Modulation), which allows it to transmit more data bits in each symbol, compared to 64-QAM used in 802.11n.
• Enhanced channel bonding: It supports wider channels up to 80 MHz, and even 160 MHz with channel bonding, which significantly increases throughput by combining multiple channels into one larger channel.
