There are very few IoT chips that support 5 GHz. Espressif finally announced the C5 with dual-band but otherwise all ESP32s are on 2.4 GHz. Thread is 100% 2.4

There are very few IoT chips that support 5 GHz. Espressif finally announced the C5 with dual-band but otherwise all ESP32s are on 2.4 GHz. Thread is 100% 2.4 GHz. Seems the plan is to move high bandwidth applications, and most Wi-Fi users to 5 GHz leaving just IOT devices on 2.4.
