Network Access

What is the recommended approach for avoiding co-channel congestion when installing access points that use the 2.4 GHz frequency?

  • A different nonoverlapping channels
  • B one overlapping channel
  • C one nonoverlapping channel
  • D different overlapping channels
Explanation

To minimize contention and interference in the 2.4 GHz band, nearby access points should be placed on different nonoverlapping channels. Using the same channel increases co-channel contention, and using overlapping channels creates adjacent-channel interference. Distinct nonoverlapping channels are the standard design practice for 2.4 GHz WLAN deployments.
