How many frequency bands of radio waves in walkie talkie?

According to its wavelength, radio wave can be divided into four bands.

The band with the shortest wavelength is called microwave, and the wavelength is about 10-4m ~ 1m;

The wavelength longer than microwave is short wave (1-102 m), medium wave (102-103 m) and long wave (103-105 m)
