Zorluk: OrtaWireless Network Deployment and Standards

A network technician is deploying three wireless access points across a single-floor office space to provide coverage on the 2.4 GHz frequency band. To minimize co-channel interference and avoid adjacent-channel overlap while maintaining stable connectivity, which of the following deployment configurations should the technician implement? (Select TWO.)

  1. Assign the access points to channels 1, 6, and 11 respectively.Cevap
  2. Set the channel width on all 2.4 GHz access points to 20 MHz.Cevap
  3. C
    Assign the access points to channels 1, 3, and 5 to keep frequencies closely grouped.
  4. D
    Enable 40 MHz channel bonding on all access points to double theoretical throughput.
  5. E
    Assign the access points to channels 2, 7, and 12 to avoid default factory settings.

Cevap

The technician should assign the access points to channels 1, 6, and 11, and configure all 2.4 GHz access points to a 20 MHz channel width.
In 2.4 GHz Wi-Fi deployments, using channels 1, 6, and 11 ensures that adjacent access points operate without spectrum overlap. Restricting the channel bandwidth to 20 MHz preserves these non-overlapping boundaries, preventing co-channel and adjacent-channel interference across the multi-AP environment.

Adım Adım Çözüm

1
Identify the non-overlapping channel scheme for the 2.4 GHz band
Channels 1, 6, and 11 are identified as the primary 20 MHz non-overlapping channels.
The 2.4 GHz band has 11 usable channels in standard regulatory regions, each 20 MHz wide with 5 MHz spacing, meaning only channels 1, 6, and 11 do not overlap.
2
Determine the appropriate channel width configuration
A 20 MHz channel width is selected for all access points.
Bonding to 40 MHz in 2.4 GHz leaves insufficient spectrum for three distinct APs without mutual interference.
