How WiFi 6 (REALLY) works --- Is it a SWITCH? Feat. the Clear to Send Podcast

Wi-Fi 6 improves wireless network efficiency through features like OFDMA and multi-user MIMO, but it's not equivalent to a network switch due to its half-duplex nature 0:15-0:24.

Key Takeaways:
• Wi-Fi 6 is more like a hub than a switch because wireless technology is half-duplex, creating shared contention domains 6:31-6:42
• OFDMA allows Wi-Fi 6 to divide channels into smaller resource units, improving efficiency in high-density environments 14:44-15:33
• Multi-user MIMO has limited practical application because it requires physical separation between devices and creates overhead 9:01-9:57
• Wi-Fi 6 benefits are most noticeable when both access points and client devices support the technology 18:13-18:31
• BSS coloring helps reduce co-channel interference in congested areas like apartment complexes 42:01-42:36

Wi-Fi 6 represents a significant step forward for wireless networks, particularly in high-density environments like stadiums and apartment complexes, though its benefits may be limited in typical home settings.
