Setting APs on different channels primarily reduces which type of interference?

• A. Cross talk
• B. Power leakage
• C. Signal reflection
• D. Gateway looping

Answer: (A)

Setting APs on different channels targets interference between nearby wireless devices. When multiple access points share the same or overlapping channels, their radio signals collide and degrade each other’s performance, a phenomenon often described as cross talk. By placing neighboring APs on non-overlapping channels, you minimize overlap in the frequency band, reducing concurrent transmissions that interfere with one another and thereby improving overall network performance. Power leakage refers to energy escaping through hardware or cabling, which channel choice doesn’t address. Signal reflection (multipath) is caused by the physical environment and can be mitigated by placement and antenna patterns, not by simply changing channels. Gateway looping is a routing issue in the network layer and is unrelated to how channels are assigned.
