Perhaps the most important new capability introduced with Wi-Fi 6 is Orthogonal Frequency Division Multiple Access (OFDMA). This RF modulation technique allows multiple Wi-Fi 6 clients to simultaneously receive data during the same transmit opportunity. Allowing more information for multiple devices to be transmitted in parallel during a particular window of opportunity, all while reducing some of the traditional overhead of sending the same amount of information independently. OFDMA divides a channel into further subcarriers compared to Orthogonal Frequency Division Multiplexing (OFDM) https://www.cisco.com/c/en/us/solutions/cisco-on-cisco/enterprise-wifi-6.html
