A network administrator is designing a wireless network layout for a new office floor operating on the 2.4 GHz frequency band. To minimize co-channel interference while ensuring stability and reliable coverage across multiple access points, which of the following configuration options should the administrator select? (Select TWO.)

  1. Deploy access points using non-overlapping channels 1, 6, and 11.Cevap
  2. Set the 2.4 GHz channel width to 20 MHz across all access points.Cevap
  3. C
    Deploy access points using adjacent channels 2, 7, and 12.
  4. D
    Set the 2.4 GHz channel width to 40 MHz across all access points.

Cevap

To minimize co-channel and adjacent-channel interference in a 2.4 GHz wireless network deployment, access points should be configured to use non-overlapping channels 1, 6, and 11 with a channel width of 20 MHz.
In 2.4 GHz Wi-Fi deployments, channels 1, 6, and 11 are the only standard 20 MHz channels that do not overlap with one another. Using a 20 MHz channel width ensures that adjacent access points do not spill over into neighboring frequencies, preserving throughput and minimizing interference.

Adım Adım Çözüm

1
Identify the standard non-overlapping channels in the 2.4 GHz spectrum.
Channels 1, 6, and 11 are spaced 25 MHz apart, preventing frequency overlap when operating at standard widths.
Adjacent channel assignments cause high packet loss and interference.
2
Determine the appropriate channel width for a multi-AP 2.4 GHz deployment.
Select 20 MHz channel width rather than 40 MHz channel bonding.
40 MHz channel widths cover 8 out of 11 available 2.4 GHz channels, making non-overlapping AP deployments impossible.
