問題文
An engineer turns on the 6-GHz band for a Mist site and leaves every radio setting at the value it shipped with. Which statement describes the channel width that the radios will use in that band, and why that width was chosen?
選択肢
- The radios start at 20 MHz, because that width leaves the most channels free for the neighboring sites or tenants that have to share the same spectrum.
- The radios start at 40 MHz, because that width is the compromise that suits regions where only 500 MHz of spectrum has been released for indoor use.
- The radios start at 80 MHz, because that width lines up with the scan channels that endpoints look at first and it keeps the radiated power ceiling high.
- The radios start at 160 MHz, because that width is the widest one that an indoor or outdoor radio is allowed to use under the low power rules.
