One museum AP is set to 80 MHz while a neighboring AP uses 20 MHz. What does channel width primarily describe?
Select an answer to reveal the explanation.
Short Explanation
Channel width is how wide a slice of spectrum the BSS sits on — 20, 40, 80, and friends. It is not PoE watts, switch speed, or SSID count. Wider can mean more throughput potential and more neighbors to bump into.
Full Explanation
Channel width (channel bandwidth) defines how much contiguous RF spectrum a BSS occupies, commonly 20, 40, 80 MHz, or wider where supported. An 80 MHz BSS therefore uses more spectrum than a 20 MHz neighbor and has different coexistence implications. Width is unrelated to PoE class, Ethernet link speed, or the count of SSIDs. Technicians must apply the design's width setting knowing it trades capacity potential against interference and utilization exposure.
