Difficulty: EasyWireless Network Deployment and Standards

An organization is upgrading its wireless network to support high-throughput applications in a conference room. The network administrator decides to deploy access points supporting the IEEE 802.11ac (Wi-Fi 5) standard. Which operating frequency band is exclusively utilized by the IEEE 802.11ac standard for wireless data transmission?

  1. 5 GHz bandAnswer
  2. B
    2.4 GHz band
  3. C
    6 GHz band
  4. D
    900 MHz band

Answer

The IEEE 802.11ac standard exclusively utilizes the 5 GHz frequency band.
The IEEE 802.11ac (Wi-Fi 5) standard was designed specifically for high-throughput local wireless networks by operating exclusively in the 5 GHz spectrum. This allows for wider channel bonding (up to 80 MHz or 160 MHz) and less signal congestion compared to the crowded 2.4 GHz spectrum.

Step-by-Step Solution

1
Identify the wireless standard specified in the question
The target standard is IEEE 802.11ac (Wi-Fi 5).
Different Wi-Fi standards are defined by the IEEE to operate on specific radio frequency bands.
2
Determine the operating frequency band for 802.11ac
IEEE 802.11ac is defined strictly to operate within the 5 GHz spectrum.
By focusing solely on 5 GHz, 802.11ac supports mandatory wider channel bonding (such as 80 MHz and optional 160 MHz channels) and higher density modulation.
