So far it sounds very good, because there is much less radiant power over a certain area and/or by concentrating the signal, you can improve quality or bandwidth (as advertised) by strengthening signal/noise ratio, and that is done only by strengthening the signal inside each beam, several times, maybe up to 10 times or one order of magnitude greater than with 4G over a large area. But it has to be both ways, so the 5G phones, to get the bandwidth already advertised for 5G would have to strengthen the signal too, though only inside the beam (or maybe they don't need the same upload speeds). So the devices would use less power or the same, while emitting at higher power density inside the beam. But what happens if the head or heart of that person or another nearby gets in the way of the beam?
And this image tries to suggest the multitude of beams within a a city with many 5G users. It is not real, just an artist's imagination at work. The real one would look like a 3D web of fat beams, linking each device to one of the towers, that can be much more complex, depending of number of devices. But what if one cell phone is homed simultaneously by many beams from several towers from same provider or from different providers, like if a hacker would launch from that phone many requests to many towers in the same time? You could get much greater signal density per person, like hundreds of times greater that it is physically possible with 4G. Or a hacker (or conspirators whatever) configures a number of cell phones close to target (that can be a device the targeted person is wearing) while nobody has no idea idea of what's happening and "beam" that target with a signal that could be hundreds of times greater than a normal phone is transmitting to a tower in 4G and that can be very bad.
Recently ran into a phone plan that says "5G Nationwide". Did they get so far so quick?
I vaguely remember Trump era data safety concerns about 5G coming from China. Could the banning of Chinese technology mean that they don't do certain things that i'm going to talk about?
It's not about data or privacy concerns. They know everything they need to know about everybody in real time through current technology (and now that include 5G).
The way 5G works is very similar to phased arrayed radars currently used on most advanced fighter jets. Unlike those who use the beam to dynamically scan an area, similar to an old CRTs, to save power, 5G antennas, both from towers and phone using the same technology can direct a beam on the other antenna, even when in motion.
Mechanically static or with limited motion, radars' antennas can, instead of actively scanning a region, direct a beam on and fry an opponents device electronics. Pretty much like in old CRT TVs when both horizontal and vertical steering or scanning circuits broke and the electron beam was concentrating in the middle of the screen (but could have been anywhere if so intended). That is directing precisely a beam of microwaves powerful enough and keep it on a target long enough to disable it.
Think about. We now have 5G capable towers all around. It is enough to direct a number of them to one single phone or person to make it sick enough or create symptoms that could be classified as COVID. Rest is done in hospitals.
And now i think this is what happened in the two years, they selectively took out the oldest and most knowledgeable that have seen a lot and they could turn the balance against them. They may have not been so selective in 1918 when they only had Eiffel Tower.
