A network administrator is planning a WLAN for a soccer stadium and was advised to use MU-MIMO to improve connection performance in high-density areas. The project requires compatibility with clients connecting using 2.4GHz or 5GHz frequencies. Which of the following would be the BEST wireless standard for this project?
Correct Answer: B
* The question asks about the best wireless standard for a WLAN project that involves MU-MIMO and dual-band frequencies.
* The answer is not A, because 802.11ac is a wireless standard that supports MU-MIMO, but only operates on the 5GHz frequency band, which does not meet the project requirement of compatibility with 2.4GHz clients.
* The answer is not C, because 802.11g is a wireless standard that operates on the 2.4GHz frequency band, but does not support MU-MIMO, which is a key feature for improving connection performance in high-density areas.
* The answer is not D, because 802.11n is a wireless standard that operates on both 2.4GHz and 5GHz frequency bands, but only supports SU-MIMO (Single-User Multiple-Input Multiple-Output), which is less efficient and scalable than MU-MIMO for multiple concurrent connections.
* The answer is B, because 802.11ax is a wireless standard that supports MU-MIMO and operates on both
2.4GHz and 5GHz frequency bands, which meets the project requirements of compatibility and performance. 802.11ax is also known as Wi-Fi 6, and it offers higher data rates, lower latency, and better energy efficiency than previous wireless standards.
