- OFDMA divides a signal carrier into multiple sub-carriers to minimize distortion and degradation, it further reduces overhead and latency. Access to various users is granted in OFDMA by assigning subsets of these subcarriers to individual users. Hence it allows up to 25 to 30 clients to share a channel simultaneously, thereby improving efficiency.
- WiFi 5/ 4 adopts OFDM, an older standard to encode and transmit data that can dispatch traffic only to a single recipient at a time. Due to which it can create lag while client users have to wait their turn for data.
- The WiFi 6 using OFDMA can transmit data to multiple devices simultaneously, splitting traffic into smaller packets to eliminate queues.
