There is a considerable amount confusion about 5G, Some of the statements are at best misleading and in many cases out right wrong. Yes, I have concerns about the harm electromagnetic radiation causes and am concerned about the additional harm that the mmwave portion of 5 G will cause. I also know there is very little mmwave 5G currently deployed anywhere in the world. Canada like many other countries has not even auctioned off the frequencies yet- in the case of Canada the spectrum auction will not occur until 2024 at the earliest. Yes, the 5G frequencies below about 6 Ghz are in use virtually everywhere and yes there are serious health and environmental issues the use of these frequencies has caused. I know from personal experience the harm that even a short (30 sec or so) exposure to 10 GHz can cause. Look at the left side of my face. The paralysis there is the result of an operation to remove a massive vestibular schwannoma– Usually called an Acoustic Neuroma, a benign tumour in the myelin sheath/Schwann cells of the 8 th cranial nerve. Don’t let the “benign” nature of the tumour mislead lead one to think it is a minor tumour. Over 20 hours of brain surgery in 2 operations and more follow up treatment it is a serious operation that requires the breaking open the skull to conduct the operation and a cumulative total of 6 months ( in my case of time spent in the hospital to recover – my tumour was MASSIVE – the largest I have heard of anyone having and required extra operating and recovery time)” I had originally planned to explain 5 G in one video but once I started preparing for it realised the topic would quickly overwhelm most people and they would need a break to process the information. This video will be about the formal definition of 5G as defined and set out in the official protocol documents for 5G, they are part of International Mobile Telecommunications-2020 (IMT-2020 Standard)https://www.itu.int/osg/spu/imt-2000/technology.html under the auspices of 3rd Generation Partnership Project (3GPP) reading and understanding the document is heavy reading that few apart from industry people will do. There is nothing significant about the use of 5 in 5G other than it is a marketing term referring to the 5 th generation of Cell Phone Technology. The next protocol they are currently working on is 6G and scheduled to be deployed starting in 2030 (don’t think they will make that date) and they are even working on developing 7G expected to be deployed in 2040. For me the protocol has only a few essential points to focus on. The new 5G developments include what is referred to as a “beam forming antenna”. In simple terms this means the main beam can be focused into a specific direction. The main advantage for this technology is it at least in theory requires less power to broadcast in a narrow defined cone than broadcasting multi directional, this also will allow more devices to connect through a given antenna. Other key points re 5G is it is multiple frequencies and the technology is being unleashed on the public in stages making it difficult to really nail down 5 G issues as the occur. The frequencies used and timing of their release will vary between countries. The frequencies are classed into 3 groupings – low, mid and high band frequencies. In most locations world wide the low and mid band frequencies are already in use or being deployed. These frequencies are also grouped into a category called called Frequency Ranges (FR) FR1 is from 0.41 Ghz to 7.125 GHz (10 MHz to 7125 MHz) and FR2 (also referenced as mmwave is from 24.25 GHz to 71 GHz (when I started preparing this a few days ago the upper bound was 52.6 GHz – specs keep being changed now the upper bound is 71 GHZ. Radio frequencies are specified in terms of their cycles per sec or the wave length – the distance the wave travels in 1 sec. The numbers are related by the formulas  c = λ · f         λ = c / f = c · T         f = c / λ where “c” is the speed of light 299,792,458 m/s λ is the wave length and f is the frequency in cycles per sec. A look a this spread sheet will give one an idea of the progression of frequencies as the wave length is decreased. To confuse the discussions even more the various Telcos use their own marketing terms for at times essentially the same sub set of their 5 G usage. Recently Verizon began using the term 5G Ultra Wideband. In the case of Verizon this term refers to the use of a wide frequency >500 MHz. Th wider band opens up the ability to carry more data, unfortunately it also opens up a little studied area of Radio Frequency. The complications the brillion precursor. A discussion of the precursor effects is a complicated discussion quickly getting into the area of Quantum Physics https://scientists4wiredtech.com/what-are-4g-5g/brillouin-precursors/ Another area of Radio Frequency that is part of Quantum Physics is, is radiation a wave or particle. The answer is it is both according
