Expert Answers
What is the difference between Wi-Fi 6 and Wi-Fi 5?
Wi-Fi 6 (802.11ax) significantly improves upon Wi-Fi 5 (802.11ac) by offering higher speeds, better efficiency in handling multiple devices simultaneously, and more advanced features like OFDMA and MU-MIMO.
What is OFDMA?
OFDMA (Orthogonal Frequency-Division Multiple Access) is a key feature of Wi-Fi 6 that allows the access point to transmit data to multiple devices simultaneously, improving overall network performance and reducing latency.
What is the role of Target Wake Time (TWT) in Wi-Fi 6?
TWT (Target Wake Time) in Wi-Fi 6 allows devices to schedule their communication with the access point, improving energy efficiency by reducing unnecessary power consumption.
How does Wi-Fi 6 improve security?
Wi-Fi 6 incorporates enhanced security protocols to mitigate vulnerabilities associated with previous standards. WPA3 is often used for this purpose.
