Zorluk: OrtaWireless Networking Standards and Technologies

A network technician is optimizing wireless coverage for a two-story office facility that hosts both legacy inventory scanners restricted to the 2.4 GHz band and modern laptops requiring high bandwidth. Which TWO design practices should the technician implement to minimize signal degradation and maximize network performance? (Select TWO.)

  1. Assign non-overlapping channels 1, 6, and 11 to adjacent access points operating in the 2.4 GHz spectrum.Cevap
  2. Migrate high-bandwidth devices to the 5 GHz band to leverage additional non-overlapping channels and higher throughput.Cevap
  3. C
    Configure neighboring 2.4 GHz access points to use channels 2, 4, and 6 to evenly space coverage across the spectrum.
  4. D
    Disable 5 GHz radios across all access points so that all connected devices share a single unified frequency band.

Cevap

The technician should assign non-overlapping channels (1, 6, and 11) to adjacent 2.4 GHz access points and migrate high-bandwidth devices to the 5 GHz frequency band.
To maintain reliable wireless performance in dual-band deployments, 2.4 GHz access points must use non-overlapping channels (1, 6, and 11) to prevent interference. Simultaneously, steering high-bandwidth clients to the 5 GHz band leverages greater spectrum availability and wider channel widths.

Adım Adım Çözüm

1
Analyze the 2.4 GHz frequency spectrum constraints.
Identify that 2.4 GHz channels are 20 MHz wide but spaced only 5 MHz apart, making channels 1, 6, and 11 the standard non-overlapping set.
Using non-overlapping channels on neighboring access points prevents co-channel and adjacent-channel interference.
2
Evaluate client band requirements and capacity planning.
Determine that bandwidth-heavy devices perform better on the 5 GHz band, which provides broader channels and less spectrum congestion.
Segmenting legacy low-throughput devices on 2.4 GHz and performance-demanding devices on 5 GHz optimizes overall throughput.
