Additionally, whereas AM radio operates within the LF and MF bands, FM radio operates within the VHF band . 0.03 to 0.3 GHz. In other applications, this frequency range is used for transmitting things like TV broadcasts, Wi-Fi, GPS and Bluetooth signals. The FCC is driving key spectrum initiatives to enable 5G across Low-band, Mid-band and High-Band In many countries, 5G system are still in trial and frequency bands yet to be finalized. A television station broadcast Radio Frequency (RF) channel is allocated 6 MHz of bandwidth for over-the-air transmission in part of the VHF or UHF Radio Frequency Band. You can see that the basic scheme divides up the spectrum into decades (factors of ten), aligned with frequencies that start with 3 (e.g., 3 MHz, 30 MHz, 300 MHz). The pulse method takes up a lot more spectrum to work reliably, hence the ultra-wideband nomenclature. Question|Asked by Elking. 0.3 to 1 GHz.
