Zorluk: KolayTroubleshooting Wireless Connectivity and Signal Issues

A network administrator is configuring three adjacent 2.4 GHz wireless access points in an office floor plan. Which combination of channels should be assigned to these access points to prevent co-channel and adjacent-channel interference?

  1. Channels 1, 6, and 11Cevap
  2. B
    Channels 1, 2, and 3
  3. C
    Channels 2, 4, and 6
  4. D
    Channels 5, 10, and 15

Cevap

Channels 1, 6, and 11
Channels 1, 6, and 11 are the standard non-overlapping 20 MHz channels in the 2.4 GHz Wi-Fi spectrum. Assigning these distinct channels to adjacent access points prevents signal degradation caused by channel overlap.

Adım Adım Çözüm

1
Identify the frequency band and channel separation requirements for 2.4 GHz Wi-Fi.
Standard 2.4 GHz 802.11 channels require 20 MHz of bandwidth, but center frequencies are spaced only 5 MHz apart.
To avoid frequency overlap, channels must have center frequencies spaced at least 20 MHz (4 channel intervals) apart.
2
Determine the non-overlapping channel set.
Selecting channels 1, 6, and 11 provides the necessary 25 MHz separation between channel center frequencies.
Channels 1, 6, and 11 allow multiple adjacent access points to operate without interfering with one another.
