Two neighboring municipal building APs are both on the same 5 GHz channel and clients report sluggish performance during peak hours. What interference type should the tech identify?
Select an answer to reveal the explanation.
Short Explanation
Same channel, two talkers—everyone waits their turn on one shared walkie-talkie frequency. That is co-channel interference, not a password problem. Plan or correct channels so neighbors are not fighting for the same airtime.
Full Explanation
Co-channel interference occurs when multiple BSSs operate on the same channel and must contend for the medium, reducing available airtime and harming performance. Peak-hour sluggishness with confirmed same-channel neighbors is a classic CCI symptom. Adjacent-channel interference involves overlapping but non-identical channels/widths and is a different label.
