Zorluk: OrtaWireless Networking Standards and Technologies

A network technician is configuring three wireless access points (APs) positioned along a hallway to cover a office floor using the 2.4 GHz band. Access Point 1 has been configured to use Channel 1. To prevent adjacent channel interference and maximize wireless performance, which non-overlapping channel assignment should the technician select for Access Point 2 and Access Point 3?

  1. Channel 6 for Access Point 2 and Channel 11 for Access Point 3Cevap
  2. B
    Channel 2 for Access Point 2 and Channel 3 for Access Point 3
  3. C
    Channel 3 for Access Point 2 and Channel 7 for Access Point 3
  4. D
    Channel 4 for Access Point 2 and Channel 8 for Access Point 3

Cevap

The technician should assign Channel 6 to Access Point 2 and Channel 11 to Access Point 3.
In North America and standard international 2.4 GHz Wi-Fi deployments, channels 1, 6, and 11 are the primary 20 MHz non-overlapping channels. Configuring AP 1 on Channel 1, AP 2 on Channel 6, and AP 3 on Channel 11 ensures that signal coverage areas can border each other without suffering from adjacent-channel interference.

Adım Adım Çözüm

1
Identify the operating frequency band
The deployment uses the 2.4 GHz wireless spectrum.
The 2.4 GHz band has 11 to 14 available channels spaced 5 MHz apart, but standard channel width is 20 MHz.
2
Determine non-overlapping channels in the 2.4 GHz band
Channels 1, 6, and 11 are separated by 25 MHz (5 channels), which prevents frequency spectrum collision.
Any channel choice between 1, 6, and 11 causes adjacent channel interference.
3
Assign remaining non-overlapping channels
With AP 1 on Channel 1, AP 2 should be assigned Channel 6 and AP 3 should be assigned Channel 11.
This configuration maximizes throughput and eliminates adjacent-channel interference between adjacent access points.
