Zorluk: KolayWireless Network Deployment and Standards

A network administrator is planning a wireless deployment in a facility using the 2.4 GHz frequency band in North America. To avoid adjacent-channel interference between neighboring access points, which of the following standard 2.4 GHz channels should be selected for cell assignment? (Select TWO.)

  1. Channel 1Cevap
  2. Channel 6Cevap
  3. C
    Channel 2
  4. D
    Channel 3
  5. E
    Channel 4

Cevap

Channel 1 and Channel 6 are standard non-overlapping 2.4 GHz channels.
In the 2.4 GHz Wi-Fi band (802.11b/g/n), each 20 MHz channel requires a 25 MHz separation between center frequencies to be completely non-overlapping. In North America, the three designated non-overlapping channels are 1, 6, and 11. Therefore, selecting Channel 1 and Channel 6 provides non-overlapping wireless coverage.

Adım Adım Çözüm

1
Identify the frequency band and regional standard
The scenario specifies the 2.4 GHz Wi-Fi spectrum under North American channel allocation rules.
Standard 2.4 GHz channels operate on frequencies spaced 5 MHz apart, requiring a separation of 20 MHz or 25 MHz between center frequencies to prevent overlapping.
2
Determine the non-overlapping channel set
Channels 1, 6, and 11 do not overlap with each other in the 2.4 GHz spectrum.
Choosing non-overlapping channels prevents co-channel and adjacent-channel interference between neighboring access points.
3
Evaluate the provided choices
Channel 1 and Channel 6 are non-overlapping options, while Channels 2, 3, and 4 overlap with Channels 1 and 6.
Selecting Channel 1 and Channel 6 ensures clean wireless cell boundaries.
