On Spectrum

Electromagnetic Spectrum is the wide range of all types of electromagnetic radiation starting from Extremely Low Frequency (ELF) all the way to the extremely high end, which contains Gamma Rays, a form of nuclear radiation.  Radiation is another word for energy, which travels and spreads out as it goes.


For example, radio waves that make it possible for a radio station to transmit music and visible light from a lamp in your house and are two types of electromagnetic radiation (energy), both of which are classified as Non-Ionizing Radiation.  This is different from Ionizing Radiation, which is generally considered to be hazardous to humans and only occurs at a much higher frequency ranges towards the far end of the Electromagnetic Spectrum.


5G technology can be delivered using a wide range of radiofrequencies, also known as radio waves, contained within the Radio Spectrum, which is classified as Non-Ionizing Radiation.  Some of these same radio frequencies have been in use for many years to deliver services such as television broadcasting, wireless broadband and other types of transmissions that already exist in our every-day environment.


It is important to note that all frequencies that may possibly be used for 5G in the future fall within the Radio Spectrum, all of which is classified as Non-Ionizing Radiation. Radiofrequencies in the Radio Spectrum do not carry enough energy to directly damage human cells.


Initially, mobile phone companies have deployed 5G in Radio Spectrum frequency bands which are close to those already in use for previous generations of mobile technology such as 3G and 4G. These frequency bands tend to be in the low- and mid-ranges of the Radio Spectrum, although 5G can also make use of frequencies in the higher range of the Radio Spectrum.
