A stadium is planning a high-density Wi-Fi deployment for a concert. The network will use 5 GHz with 80 MHz channels. The engineer is concerned about co-channel interference between APs. What is the best way to minimize co-channel interference while maintaining high throughput?

Use 40 MHz channels as a compromise between data rate and channel count.

Use only 2.4 GHz to avoid interference from other bands.

Use 160 MHz channels to maximize data rates, even though fewer channels are available.

Use 20 MHz channels to increase the number of non-overlapping channels, even though peak data rates decrease.

A company is deploying new Wi-Fi 6E access points and wants to ensure that only devices that support 6 GHz can use that band. They also want to avoid interference from legacy devices. What is the primary advantage of the 6 GHz band in this scenario?

It is backward compatible with all older Wi-Fi devices.

It offers better range than 2.4 GHz due to lower frequency.

It provides a large amount of clean spectrum with no legacy interference.

It uses the same channels as 5 GHz for easier planning.

A university library has a high-density area where many students use laptops and smartphones. The engineer wants to maximize throughput for these clients. Which band should be prioritized for this environment, and why?

5 GHz, because it offers more non-overlapping channels and higher data rates.

6 GHz, because it is available on all client devices.

2.4 GHz, because it has better range and penetrates walls more effectively.

2.4 GHz, because it is less congested than 5 GHz.
