A network technician is installing a new 2.4 GHz wireless access point in a small branch office. To minimize wireless noise and avoid adjacent-channel interference with nearby access points, the technician needs to select standard non-overlapping channels. Which of the following channels should the technician select? (Select TWO.)

  1. Channel 1Cevap
  2. Channel 6Cevap
  3. C
    Channel 3
  4. D
    Channel 9

Cevap

The correct options to select are Channel 1 and Channel 6.
In 2.4 GHz Wi-Fi deployments, the standard non-overlapping 20 MHz channels are Channel 1, Channel 6, and Channel 11. Selecting Channel 1 and Channel 6 ensures that the access points operate on distinct frequencies without overlapping into adjacent channels.

Adım Adım Çözüm

1
Identify the operating frequency spectrum specified in the prompt.
The network operates on the 2.4 GHz Wi-Fi band.
Channel assignment rules vary based on whether 2.4 GHz, 5 GHz, or 6 GHz bands are being configured.
2
Determine the standard non-overlapping channels available in the 2.4 GHz band.
The standard 20 MHz non-overlapping channels in North America/standard 802.11 deployments are channels 1, 6, and 11.
2.4 GHz channels are spaced 5 MHz apart, while each channel occupies 20 to 22 MHz of bandwidth, requiring 5 channels of separation to prevent overlap.
3
Match the valid non-overlapping channels with the provided choices.
Channel 1 and Channel 6 are correct non-overlapping choices. Channel 3 and Channel 9 cause adjacent-channel interference.
Choosing overlapping channels leads to co-channel/adjacent-channel noise and frame collisions.
