 5G Will Be Delivered as Phased Array (Focused Beam) Radiation
The single most important fact about 5G that nobody is talking about is called “phased array.” It will totally change the way cell towers and cell phones are constructed and will transform the blanket of radiation which has enveloped our world for two decades into a million powerful beams whizzing by us at all times....
 5G Beams Aimed Directly at People Will Be Unavoidable
5G is going to be at a much higher frequency range, which means the antennas are going to be much smaller— small enough to fit inside a smartphone... they are going to concentrate their energy in narrow, steerable high power beams.... The arrays are going to track each other, so that wherever you are, a beam from your smartphone is going to be aimed directly at the base station (cell tower), and a beam from the base station is going to be aimed directly at you. If you walk between someone’s phone and the base station, both beams will go right through your body. The beam from the tower will hit you even if you are standing near someone who is on a smart phone. And if you are in a crowd, multiple beams will overlap and be unavoidable.
 Steerable 5G Beams Will Invade Flesh at Insane Power Densities
At present, smartphones emit a maximum of about two watts, and usually operate at a power of less than one watt. That will still be true of 5G phones. However inside a 5G phone there may be 8 tiny arrays of 8 tiny antennas each, all working together to track the nearest cell tower and aim a narrowly focused beam at it. The FCC has recently adopted rules allowing the effective power of those beams to be as much as 20 watts. Now if a handheld smartphone sent a 20-watt beam through your body, it would far exceed the exposure limit set by the FCC. What the FCC is counting on is that there is going to be a metal shield between the display side of a 5G phone and the side with all the circuitry and antennas. That shield will be there to protect the circuitry from electronic interference that would otherwise be caused by the display and make the phone useless. But it will also function to keep most of the radiation from traveling directly into your head or body, and therefore the FCC is allowing 5G phones to come to market that will have an effective radiated power that is ten times as high as for 4G phones.
 No One Yet Knows Exactly What 5G Beams Will Do Living Flesh
What this willl do to the user's hands the FCC does not say. And who is going to make sure that when you stick a phone in your pocket, the correct side is facing your body?  And who is going to protect all the bystanders from radiation that is coming in their direction that is ten times as strong as it used to be?
    5G Beams at 300 Watts is Enormous Radiated Power
And what about all the other 5G equipment that is going to be installed in all your computers, appliances and automobiles?  The FCC calls handheld phones “mobile stations.” Transmitters in cars are also “mobile stations.” But the FCC has also issued rules for what it calls ”transportable stations,” which it defines as transmitting equipment that is used in stationary locations and not in motion, such as local hubs for wireless broadband in your home or business. The FCC's new rules aequipment.
5G Beams Will Be Ultra-Short Millimeter Waves
The situation with cell towers is if anything,worse. So far the FCC has approved bands of frequencies around 24 GHz, 28 GHz, 38 GHZ, 39 GHz and 48 GHz for use in 5G stations and is proposing to add 32 GHz, 42 GHz, 50 GHz, 71-76 GHz, 81-86 GHz and above 95 GHz to the soup. These have tiny wavelenghts and require tiny antennas.  At 48 GHz, an array of 1,024 antennas will measure only 4 inches square. And the maximum radiated power from a base station will probably not be that large—tens or hundreds of watts.....But arrays containing such large numbers of antennas will be able to channel the energy into highly focused beams, and the effective radiated power will be enormous.
 Tiny 5G Antennas Will Propagate Enormous Wattage
The rules adopted by the FCC allow a 5G base station operating in the millimeter range to emit an effective radiated power of up to 30,000 watts per 100 MHz of spectrum. And when you consider that some of the frequency bands the FCC has made available will allow telecom companies to buy up to 3 GHz of contiguous spectrum at auction, they will legally be allowed to emit an effective radiated power of up to 900,000 watts if they own that much spectrum. They will be small rectangular structures monted on top of utility poles.
 5G Will Be Delivered in Huge Doses To Accomodate the Internet of Things
 The reason the companies want so much power is because millimeter waves are easily blocked by objects and walls and require tremendous power to penetrate inside buildings and communicate with all the devices that we own that are going to be part of the Internet of Things. The reason such tiny wavelenghths are required is because of the need for an enormous amount of bandwidth a hundred times as much bandwidth as we formerly used--in order to have smart homes, smart businesses, smart cars and smart cities, i.e, in order to connect so many of our possessions, big and small, to the Internet and make them do everything we want them to do as fast as we want them to do it....
The FCC Provides No Answers on 5G Environmental Effects
Base stations have to be very close together--a hundred meters apart in cities--and they have to blast out their signals in order to get them inside of homes and buildings. And the only way to do this economically is through phased arrays and focused beams that are aimed directly at their targets. What happens to birds who fly through the beams, the FCC does not say. And what happens to utility workers who climb utility poles and work next to these structures every day? A 30,000 watt beam will cook an egg or and eye at a distance of a few feet.
 You Can Time it Right for Maximum 5G Abuse
The power from a base station will be distributed among as many devices as are connected at the same time. When a lot of people are using their phones simultaneously, everyone's phone will slow down but the amount of radiation in each beam will be less. When you are the only person using your phone--for example, late at night-- your data speed will be blisteringly fast but most of the radiation from the cell tower will be aimed at you.
Millimeter Wave Physics: 5G Will Ricochet Deeply Into the Body
Another important fact about the radiation from phased array antennas is this: it pentrates much deeper into the human body and the assumptions that the FCC's exposure limits are based on do not apply. This was brought to everyone's attention by Dr. Richard Albanese of Brooks Air Force Base.....When an ordinary electromagentic field enters the body, it causes charges to move and currents to flow. But when extremely short electromagnetic pulses enter the body, something else happens: the moving charges themselves become little antennas that re-radiate the electromagnetic field and send it deeper into the body. These re-radiated waves are called Brillouin precursers. They become significant when either the power or the phase of the waves changes rapidly enough. 5G will probably satisfy both requirements.  This means that the reassurances we are being given-- that these millimter waves are too short to penetrate far into the body -- is not true.
