Difficulty: EasyWireless Networking Standards and Technologies

A network technician is configuring a wireless access point for a newly renovated conference room. The deployment requirements specify that the access point must use a wireless standard that operates exclusively in the 5 GHz frequency band to avoid heavy interference from legacy 2.4 GHz devices. Which IEEE 802.11 standard meets this specific requirement?

  1. 802.11acAnswer
  2. B
    802.11n
  3. C
    802.11g
  4. D
    802.11b

Answer

802.11ac
The IEEE 802.11ac standard (Wi-Fi 5) was specified to operate solely within the 5 GHz frequency band. This exclusive frequency use ensures high data rates and eliminates channel overlap issues originating from legacy 2.4 GHz devices.

Step-by-Step Solution

1
Identify the operating requirement specified in the scenario
The target wireless standard must operate strictly in the 5 GHz frequency band without utilizing 2.4 GHz.
The objective is to avoid congestion and interference present on legacy 2.4 GHz frequencies.
2
Evaluate candidate wireless standards against frequency support characteristics
802.11b and 802.11g operate at 2.4 GHz only. 802.11n operates at both 2.4 GHz and 5 GHz. 802.11ac operates exclusively at 5 GHz.
Only 802.11ac fulfills the requirement of operating exclusively in the 5 GHz spectrum.
