Difficulty: MediumWireless Networking Standards and Technologies

A network technician is installing a new wireless access point (AP) in a multi-tenant office building. A wireless spectrum survey reveals that neighboring office networks are currently operating on 2.4 GHz channels 1 and 6. To minimize adjacent-channel interference and ensure optimal wireless performance for 2.4 GHz devices, which non-overlapping channel should the technician assign to the new access point?

  1. A
    Channel 3
  2. B
    Channel 6
  3. Channel 11Answer
  4. D
    Channel 14

Answer

Channel 11 should be assigned to the new access point to complete the non-overlapping 1, 6, 11 channel scheme.
In the 2.4 GHz Wi-Fi band, the standard non-overlapping channels are 1, 6, and 11. Since existing nearby access points are configured on channels 1 and 6, selecting channel 11 allows the new access point to operate on a completely non-overlapping frequency band, eliminating adjacent-channel interference.

Step-by-Step Solution

1
Identify the frequency band and channel structure
The 2.4 GHz Wi-Fi spectrum uses 22 MHz channel widths with 5 MHz spacing between channel center frequencies, causing adjacent channels to overlap.
Understanding 2.4 GHz channel overlap is critical for proper channel planning.
2
Determine the standard non-overlapping channels in 2.4 GHz
Channels 1, 6, and 11 are the three primary non-overlapping channels available in standard regulatory domains.
These channels have sufficient frequency separation (25 MHz apart) to prevent adjacent-channel interference.
3
Evaluate the existing deployment context
Channels 1 and 6 are already occupied by neighboring APs, leaving channel 11 as the remaining non-overlapping option.
Assigning channel 11 avoids adjacent-channel interference with channels 1 and 6.
