For those of you concerned about 5G towers, satellites, smart phones and home routers, I wanted to share some sane reality with you. I not only studied physics in high school and college, but I worked with a wide range of EM (electromagnetic) equipment in the Air Force, from HF all the way through to devices which emit gamma radiation. While I’m certainly not the consummate expert, I certainly do have more than enough knowledge and hands-on experience to walk you through what’s what, what’s dangerous, what’s not, and most importantly, WHY.
Let’s start with a nice, handy graphic of the Electro-Magnetic Spectrum, courtesy of Wikipedia. Don’t worry, it’s reality, so it’s precisely the same EM Spectrum that exists in every physics textbook throughout the world, but I’ve added a couple of clarifying annotations.
5G is the fifth generation technology standard for cellular networks, which cellular phone companies began deploying worldwide in 2019, the planned successor to the 4G networks which provide connectivity to most current cellphones. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. The main advantage of the new networks is that they will have greater bandwidth, giving faster download speeds, eventually up to 10 gigabits per second (Gbps).https://en.wikipedia.org/wiki/5G
Depending upon their intended use, 5G devices fall within one of three bands:
- Low-band 5G: 600-700 MHz (0.4996541 m – 0.42827494 m)
- Mid-band 5G: 2.5-3.7 GHz (0.11991698 m – 0.08102499 m)
- High-band 5G: 25-39 GHz (0.0119917 m – 0.00768699 m)
If you’ll examine the graphic, you’ll see the LB, MB, and HB 5G annotations in red, falling in the UHF, SHF and EHF bands. If you’ll recall from yesteryear, broadcast television occupied both the VHF and UHF bands.
These frequencies have been in use for many decades. The technology behind 5G is embedded in what happens after the transmission on the frequency, mainly with additional networking capabilities between the towers and network concentrators, either along digital coaxial cable or fiber optic cable. It is there that the “magic” happens. The digital transmission over the frequencies listed above, however, are old hat, and by old, I mean very old, as in 30+ years old.
But what, of this, is dangerous, if anything?
Once you get into the Ultraviolet light range and higher, you’re dealing with “ionizing radiation.” That’s a portion of the EM spectrum where each quanta (particle) carries enough energy to knock off one or more electrons. I the UV range, this barely penetrates the first layer of skin and prolonged exposure can lead to sunburn. X-rays can penetrate tissue and exposure to high amounts can lead to various forms of cancer. Even so, focused X-rays are actually used to treat some cancers. Gamma rays contain the most energy and can penetrate otherwise impenetrable metals such as steel and even a short distance through lead. Exposure to gamma rays causes deep tissue damage and above a certain level, can result in death.
However, exposure to plain, old visible light causes you no harm whatsoever. In fact, we live in it our entire lives.
At visible light frequencies and below, there’s simply not enough energy per photon (quanta, packet) of EM energy to cause damage to biological tissue. It’s well below the energies of ionizing radiation, and not by a little, but by a LOT, as in a million times less.
Each packet of just barely ionizing radiation contains roughly 12.4 eV. An electron-volt is a unit of measure of the particle (photon) energy of a single photon of EM energy. Mid-band 5G, however, only carries 12.4 ?eV. A ? (micro) is one-millionth. Therefore, it contains one-millionth the amount of energy required to ionize electrons off atoms. For that matter, 5G contains 100,000 times less energy per photon than visible light! Yet we’re bombarded with that all the time with zero ill effects. Remember, it’s UV light, an order of magnitude more energetic than visible, that causes sunburn.
Put simply, you just can get there from here.
Now, there’s been lots of very unscientific speculation about radio frequencies below visible light causing various problems, but all such speculation has been proven to be junk. Garbage. Conspiracy theory trash.
The simple truth is that they just flat-out cannot cause any damage to human tissue. Never have, never will. That’s just plain old physics, as simply as why Styrofoam floats and a monkey wrench sinks.
5G carries about as much damaging energy as the sonic energy of leaves rustling in a light breeze i.e. none at all. You impart about a million times more damage to your body every time you stand in the shower.
