Early cellular networks, including 1G, operated at a frequency of 850 MHz and 1900 MHz. Then, 2G and 3G networks operated at additional frequency bands and spectrum around 2100 MHz, and 4G LTE technology operated at additional frequency bands and spectrum around 600 MHz, 700 MHz, 1.7/2.1 GHz, 2.3 GHz, and 2.5 GHz .

Band I ranges from 47 to 68 MHz for the European Broadcasting Area, and from 54 to 88 MHz for the Americas and it is primarily used for television broadcasting in compliance with ITU Radio Regulations (article 1.38).

Typically this can be 3.5 – 3.8 MHz , although in North America, frequencies up to 4.0 MHz can be used, although there is a broadcast band allocation above 3.8 MHz. This ham radio band can be quite noisy, especially at night as it is shared with other services and this can make it very busy.
Read moreWhat HF frequency is best?
HF users have found that using a frequency that is the MUF times 0.85 gives the best chance for good results. This is called the frequency of optimum transmission (FOT).
Read moreWhat frequencies are in the HF band?
High-frequency (HF) radio is in the 100- to 10-metre wavelength band, extending from 3 megahertz to 30 megahertz . Much of the HF band is allocated to mobile and fixed voice communication services requiring transmission bandwidths of less than 12 kilohertz.
