OFDMA (Orthogonal Frequency Division Multiple Access)

OFDMA (Orthogonal Frequency Division Multiple Access) is a technology used in wireless communications that allows multiple users to share the same network simultaneously. It divides the available radio spectrum into many small, closely spaced channels called subcarriers, which are orthogonal—meaning they don’t interfere with each other. Each user is assigned specific subcarriers, enabling efficient, high-speed data transmission for multiple users at once. This approach enhances network capacity and reduces latency, making it ideal for busy environments like Wi-Fi or 4G/5G networks.
