Difficulty: EasyWireless Networking Standards and Technologies

A network technician is configuring wireless access points for a small office using the 2.4 GHz frequency band. To minimize co-channel interference, the technician needs to use standard non-overlapping channels. Which TWO of the following channels should the technician select?

  1. Channel 1Answer
  2. Channel 6Answer
  3. C
    Channel 3
  4. D
    Channel 10

Answer

Channel 1 and Channel 6 are standard non-overlapping channels in the 2.4 GHz wireless spectrum.
In the 2.4 GHz wireless band, channels 1, 6, and 11 are the standard non-overlapping channels because each channel uses 20 MHz (or 22 MHz for DSSS) of bandwidth, requiring a separation of 5 channel numbers to prevent frequency overlap.

Step-by-Step Solution

1
Identify the frequency band being configured.
The scenario specifies the 2.4 GHz wireless band.
Channel overlap characteristics depend on the frequency band being used.
2
Recall standard non-overlapping channels in the 2.4 GHz band in North America.
The three standard non-overlapping channels spaced 25 MHz apart are Channel 1, Channel 6, and Channel 11.
Each 2.4 GHz channel occupies 22 MHz of bandwidth (20 MHz active channel plus guard bands), so channels must be separated by at least 5 channel numbers to avoid frequency overlap.
3
Select the correct options matching the standard non-overlapping channels.
Channel 1 and Channel 6 match the required standard non-overlapping channels.
Selecting Channel 1 and Channel 6 ensures zero frequency overlap between adjacent access points.
