Zorluk: OrtaWireless Network Deployment and Standards

An IT technician is deploying three access points in a line along an office corridor to provide continuous wireless coverage on the 2.4 GHz2.4\text{ GHz} spectrum. Which channel assignment pattern should be applied across the three adjacent access points to completely avoid adjacent-channel interference?

  1. Channels 1, 6, and 11Cevap
  2. B
    Channels 1, 2, and 3
  3. C
    Channels 1, 4, and 8
  4. D
    Channels 2, 6, and 10

Cevap

Channels 1, 6, and 11 should be assigned across the three adjacent access points.
In the 2.4 GHz2.4\text{ GHz} ISM band, individual standard Wi-Fi channels are 20 MHz20\text{ MHz} wide while center frequencies are spaced 5 MHz5\text{ MHz} apart. Channels 1, 6, and 11 are the three non-overlapping channels available under North American regulatory domains.

Adım Adım Çözüm

1
Analyze the frequency band requirements.
The network operates on the 2.4 GHz2.4\text{ GHz} band where each channel requires 20 MHz20\text{ MHz} of bandwidth, but channel numbers are spaced only 5 MHz5\text{ MHz} apart.
Understanding channel bandwidth vs channel spacing is required to determine spectral overlap.
2
Identify non-overlapping channel combinations.
To maintain a minimum separation of 20 MHz20\text{ MHz} between channel boundaries (or 25 MHz25\text{ MHz} between center frequencies), channels 1, 6, and 11 are selected.
This configuration ensures zero spectrum overlap between adjacent access points.
