Exam N10-008 topic 1 question 20 discussion

6 Ghz isn't shown in the net+ objectives

5GHz is the frequency range that supports the maximum number of channels and reduces interference in a high-density wireless network. The 802.11 standard for this range offers more non-overlapping channels, which reduces the likelihood of interference with other devices and improves overall network performance.

6ghz has more non overlapping channel than 5. This has nothing to do with exam objective and it's literally the correct answer.

Why is this not 6GHz? The 6GHz frequency band is part of the Wi-Fi 6E standard, which supports a larger number of channels than the 2.4GHz and 5GHz bands.

The 5GHz frequency range offers a larger number of non-overlapping channels compared to the 2.4GHz range, making it better suited for high-density wireless networks where interference can be a significant concern. By utilizing the 5GHz frequency range, network administrators can deploy more access points (WAPs) with minimal interference, allowing for improved network performance and reliability in densely populated areas.

**5GHz** Important Note: While 6 GHz offers even more channels and wider bandwidth, it's a relatively new standard and not all devices support it yet (Not an 'available' frequency). The 5 GHz band strikes a balance between channel availability and device compatibility for most high-density deployments.

I say 6ghz, why would they mention 6ghz and expect you to ignore it?

I would go with B because it says "available frequency" which 6Ghz isn't widely available in 2022.

5ghz seems like the best answer here

5ghz offers more channels, is used less and is faster over a small area. The question asks for "a high density network". This exam was published in Sept 2021 so 6ghz wifi was not an option I saw in the Todd Lammle Comptia book.

As of 2022, the fastest WiFi standard, 802.11ax-2021 (or WiFi, 6E), uses 6GHz bandwidth which provides an extra 1200MHz of channel-space. Source: https://www.wi-fi.org/file/wi-fi-6e-highlights

My bad. I misread. I think is 6ghz because high density users and 6ghz obviously better than 5ghz in that aspect.

6ghz require WPA3.

I would say 5GHz bandwidth
