What is the Maximum Wi-Fi Data Rate (Speed)?
The maximum theoretical Wi-Fi data transfer rate (throughput) varies depending on the Wi-Fi type and antenna array. For Wi-Fi 6E it can reach 2.4 Gbit/s.
Theoretically, the maximum attainable Wi-Fi® data transfer rate (throughput) will depend on the Wi-Fi type, modulation and antenna technology array. In practice, it is more difficult and the throughput is often lower, due to distance to the access point (AP), antenna characteristics, antenna orientation, signal obstructions, signal reflections, etc.
