Zorluk: KolayTroubleshooting Wireless Connectivity and Signal Issues

A technician is installing three wireless access points in a small office using the 2.4 GHz band. To prevent adjacent-channel interference between the access points, which combination of non-overlapping channels should the technician assign?

  1. Channels 1, 6, and 11Cevap
  2. B
    Channels 1, 2, and 3
  3. C
    Channels 2, 4, and 6
  4. D
    Channels 3, 7, and 11

Cevap

Channels 1, 6, and 11 should be assigned because they are the three standard non-overlapping channels in the 2.4 GHz spectrum.
Selecting channels 1, 6, and 11 ensures complete frequency separation among all three access points, eliminating adjacent-channel interference in the 2.4 GHz band.

Adım Adım Çözüm

1
Identify the operating frequency band and channel width.
The network operates on the 2.4 GHz frequency band using 20 MHz wide channels.
2.4 GHz channel numbers are spaced 5 MHz apart, requiring 4 channel spacings (20 MHz) to prevent overlap.
2
Determine the non-overlapping channel set.
Channels 1, 6, and 11 have center frequencies of 2412 MHz, 2437 MHz, and 2462 MHz, keeping their spectra separate.
Assigning 1, 6, and 11 prevents adjacent-channel interference across three neighboring access points.
