The 700 MHz band is actually the set of frequencies between 698 and 806 MHz , which puts them in the Ultra High Frequency, or UHF, range of radio frequencies. In the United States, these were and are still used as television channels 52 through 69.

The SAR is a value that corresponds to the relative amount of RF energy absorbed in the head of a user of a wireless handset. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg) .

Read moreWhat frequency range is the high frequency band?
High frequency (HF) is the ITU-designated range of radio frequency electromagnetic waves (radio waves) between 3 and 30 MHz . It is also known as the decameter band or decameter wave as the wavelengths range from one to ten decameters (ten to one hundred metres).
Read moreWhat is the frequency range of VHF and UHF?
In the United States, the frequencies used for these systems may be grouped into four general bands or ranges: low-band VHF (49-108 MHz), high-band VHF (169-216 MHz), low-band UHF (450-806 MHz), and high-band UHF (900-952 MHz). VHF represents “Very High Frequency” while UHF represents “Ultra High Frequency.”
Read moreWhich wave is better for long distance communication?
Sky waves are radio waves reflected by the ionosphere. Therefore, the propagation of these waves is not limited by the curvature of earth. So, these can be used for beyond the horizon communication. Thus, sky waves are used for communication over long (inter-continental) distances.
