Zorluk: KolayWireless Networking Standards and Technologies

A network technician is deploying a new wireless access point and must select wireless standards that do not operate on the overcrowded 2.4 GHz frequency band. Which TWO of the following IEEE 802.11 standards operate exclusively in the 5 GHz frequency band? (Select TWO)

  1. 802.11aCevap
  2. B
    802.11g
  3. 802.11acCevap
  4. D
    802.11n

Cevap

The 802.11a and 802.11ac standards operate exclusively in the 5 GHz frequency band.
Both 802.11a and 802.11ac are designed to function exclusively within the 5 GHz frequency band, making them ideal choices when eliminating 2.4 GHz band interference.

Adım Adım Çözüm

1
Determine the operating frequency band for each listed IEEE 802.11 standard
802.11a uses 5 GHz only; 802.11g uses 2.4 GHz only; 802.11ac uses 5 GHz only; 802.11n uses both 2.4 GHz and 5 GHz.
Reviewing frequency specifications identifies which standards avoid the 2.4 GHz band entirely.
2
Filter for standards that function strictly and exclusively within the 5 GHz spectrum
802.11a and 802.11ac are the only standards on the list limited strictly to 5 GHz.
Both 802.11a and 802.11ac do not support data transmission over the 2.4 GHz spectrum.
