Staff ask a city WLAN technician to set "the widest channel everywhere" for maximum speed. What caution belongs in the reply?
Select an answer to reveal the explanation.
Short Explanation
Widest-channel-everywhere is like driving a wide truck down every alley — sometimes you just scrape more parked cars. More spectrum can mean more neighbors in your lane and a busier meter. Follow the design; speed myths do not rewrite physics.
Full Explanation
Increasing channel width occupies more spectrum and can raise the chance of overlapping energy and higher observed utilization in dense environments. Throughput potential may rise when the medium is clean, but "widest everywhere" is not a universal performance win. Width settings do not exempt installers from the approved channel plan, nor do they only affect non-802.11 technologies. Technicians should explain the coexistence tradeoff rather than maximizing width by default.
