OFDMA stands for Orthogonal Frequency-Division Multiple Access. For Wi-Fi 6, it is one of the crucial features to improve network performance. Especially for IoT devices, this technology offers great advantages as they transmit small data packets. OFDMA divides channels into several small frequency allocations, allowing small amounts of data to be transmitted in parallel. A data packet therefore does not block the entire channel, which makes faster and more efficient data exchange possible.
