"WebIt is an extension of OFDM. The difference is that OFDMA is multi-user where OFDM is single-user. It has 3x higher throughput than single-user OFDM for short packets of data or multiple endpoints. OFDMA combines transmissions and sends frames to multiple endpoints simultaneously. It is more efficient with lower latency transmission. " - Csdn ofdm
