300-425 · Question #316

Which frequency band provides the widest channel availability for enterprise WLANs?

The correct answer is D. 6 GHz. The 6 GHz band, introduced by Wi-Fi 6E, provides approximately 1200 MHz of spectrum and the largest number of non-overlapping channels of any Wi-Fi frequency.

Why each option

The 6 GHz band, introduced by Wi-Fi 6E, provides approximately 1200 MHz of spectrum and the largest number of non-overlapping channels of any Wi-Fi frequency.

A2.4 GHz

2.4 GHz provides only 3 non-overlapping 20 MHz channels in most regulatory domains, making it the most spectrum-constrained Wi-Fi band.

B5 GHz

5 GHz offers more channels than 2.4 GHz but its total usable spectrum is substantially less than the 6 GHz band, limiting wide-channel deployments.

C900 MHz

900 MHz is a sub-GHz ISM band used for IoT and long-range low-throughput links, not for enterprise WLAN infrastructure.

D6 GHzCorrect

The 6 GHz band spans 5.925-7.125 GHz, delivering roughly 1200 MHz of usable spectrum. This supports up to 59 non-overlapping 20 MHz channels, far exceeding the 25 available in 5 GHz and the 3 in 2.4 GHz, making it ideal for high-density enterprise environments. The abundance of clean spectrum also means 6 GHz devices face significantly less interference from legacy equipment.
