this is a 5g cell tower that uses millimeter wave technology
5g stands for 5th generation broadband cellular technology
this video will explain the differences between 4g and 5g by examining their physics of propagation
each cellular service provider has their own frequency bands that they use and in the city i
filmed the Verizon network is dominant so we'll use their operating bands to draw comparisons
between 4g and 5g Verizon's 4g network operates in the 700 megahertz to 2.5 gigahertz range
whereas their 5g cellular technology operates at higher frequencies in two bands at 28 gigahertz
and 39 gigahertz before we continue we must first understand what frequency the megahertz's
and gigahertz's means so let's do a brief overview of what an electromagnetic wave is
electromagnetism is one of the four fundamental forces of the universe alongside gravity the
strong nuclear force and the weak nuclear force photons are the carriers of electromagnetic waves
in a vacuum electromagnetic waves travel at the speed of light these waves consisting of
a magnetic field of potential energy orthogonal or 90 degrees to an electric field of potential
energy both of these fields being orthogonal to the direction of motion of the wave
cellular networks use electromagnetic waves to transmit and receive information to and from
electronic devices by altering the characteristics of an electromagnetic wave information in the form
of zeros and ones can be encoded into the waves and then interpreted by an electronic
device in order to let's say stream a tv show listen to a song or load a webpage
how often an electromagnetic wave cycles is known as its frequency denoted by the SI unit
hertz (Hz) a three hertz electromagnetic wave cycles three times per second whereas a 30 hertz
electromagnetic wave cycles 30 times per second for the 4g cellular network operating at 700
megahertz to 2.5 gigahertz these electromagnetic waves are cycling 700 million times to 2.5
billion times per second propagating through air this corresponds to a wavelength of 0.43 meters
to 0.12 meters the 5g network operates at 28 gigahertz and 39 gigahertz cycling 28 billion
times to 39 billion times per second propagating through air this corresponds to a wavelength of
10.7 millimeters to 7.7 millimeters which is why 5g is called millimeter wave technology
both 4g and 5g operate within the microwave section of the electromagnetic spectrum because
5g wavelengths are shorter than 4g wavelengths they can deliver zeros and ones faster to 5g
capable electronic devices but this increased speed of information delivery comes at a cost
when propagating in mediums other than a vacuum like air electromagnetic waves lose energy with
each cycle a process known as attenuation 5g electromagnetic waves cycle 11 to 55 times faster
than 4g electromagnetic waves which causes them to attenuate more for the same distance traveled and
since they dissipate their energy faster more cell towers are needed for an area to have sufficient
cell coverage without dead zones as a side note naturally occurring electromagnetic waves known
as the Schumann resonances range in frequency from 7.8 to 39 hertz and therefore cycle billions of
times less per second than the waves of a 5g cell network the very low frequency Schumann resonances
attenuate much much less than a cell network and allows them to exist globally whereas a 5g cell
signal will dissipate out after just a few hundred meters and a 4g cell signal will dissipate out
after just a few kilometers i recommend you watch my video on the Schumann resonances to learn more
about how our planet naturally creates these electromagnetic waves that are felt worldwide
because of the physics of attenuation more 5g cell towers are needed than 4g cell towers in
order to blanket the same area in usable signal with the introduction of 5g cellular technology
on top of existing 1g 2g 3g and 4g networks the electromagnetic radiation of the environment's
blanketed by these networks is increasing exponentially in terms of power density
from the pre-history of humanity to the late 1800s the only electromagnetic waves that existed in the
environment were naturally occurring like the Schumann resonances natural electromagnetic
fields exist at infinitesimally smaller power densities than electromagnetic fields created
by the power grid cell towers and electronic devices the bioelectrical systems of the human
body have been shown to interact with the subtle natural electromagnetic fields of the earth for
example human brainwaves and Schumann resonances are able to enter into coherence with each other
and heart rate variability which is an important measure of health has been shown to follow
the long period power rhythms of the Schumann resonances how the bioelectromagnetic systems
of the human body interact with the much higher power and frequency cellular electromagnetic
fields is still under investigation there's more information in the video description and you can
learn the biologic mechanisms of how EMFs stressed the brain by watching my video on the subject if
