All smartphones support the Wi-Fi band below 2.4 GHz, while newer devices also support 5.0 GHz, which guarantees significantly faster data throughput, but has to make some concessions in the range.

The personal Wi-Fi hotspot on the OnePlus smartphone offers a choice of 2.4 or 5.0 GHz, and depending on which devices connect, we can use 5.0 GHz for faster network transmission.
