BI4PMQ The main advantage is the increased bandwidth, which allows for the use of high-speed modes like 4G and Wi-Fi, as well as video transmission. These common wireless technologies require a frequency range of 430 MHz or lower, while 1.2 GHz represents the minimum requirement.
However, I'm not sure about devices that use narrowband signals like FM in the high-frequency range; they seem to have little practical value.
