What is the fastest wireless protocol out right now?

As of October 2023, the fastest wireless protocol available is Wi-Fi 6E, which extends the capabilities of Wi-Fi 6 into the 6 GHz band, offering speeds up to 9.6 Gbps under optimal conditions. Additionally, Wi-Fi 7 is on the horizon, promising even higher speeds and improved performance in congested environments, but it is not yet widely deployed. For cellular networks, 5G technology can deliver ultra-fast speeds, potentially exceeding 10 Gbps in ideal scenariOS.
