What is OFDMA?

OFDMA (Orthogonal Frequency-Division Multiple Access), a technology in Wi-Fi 6 (802.11ax), improves wireless network performance by establishing independently modulating subcarriers within frequencies. This approach allows simultaneous transmissions to and from multiple clients. OFDMA divides a WiFi channel into smaller frequency allocations, called resource units (RUs). Router or AP can communicate with multiple clients by assigning them to specific RUs.
