johnc said: I had a "discussion" about this with someone earlier today.

I brought up the rollout vs the spread map. The response was "the satellites transmit in 5G also, so it won't stop until they are turned off also"



So then I asked about the spread rate, eg in Australia we had a cruise ship in which lots of people had COVID-19. Sure you could say, maybe the ship was contaminated in some way. But then how do they explain those people then infecting their family members at home when dispersed around the country and even world after the cruise. The response was that I needed to research more and I am a sheep... Click to expand...

Hey johnc. This is pretty easy to disprove as it merely represents misunderstanding of this technology from the person who made this statement. I have a background in Networking/Security and can speak to some of this.Satellites do not transmit 5G spectrum. The improvement that 5g has on its predecessors is the utilization of millimeter wave spectrum between 24GHz and 72GHz which are categorized in the Extremely high frequency (EHF) range. EHF range can only be used for communications on the ground a little more than half a mile (1KM). The atmosphere absorbs EHF range transmissions so satelite transmission would be impossible. To put that into perspective, the lower boundary of the atmosphere is about 10 miles from earth, but is 300 miles thick. Even the lowest satelites are no lower than 190 miles up....which is extremely low comparably to most communication satellites that are about 22,000 miles above the earth."Compared to lower bands, radio waves in this band have high atmospheric attenuation : they are absorbed by the gases in the atmosphere. Therefore, they have a short range and can only be used for terrestrial communication over about a kilometer. Absorption increases with frequency until at the top end of the band the waves are attenuated to zero within a few meters. Absorption by humidity in the atmosphere is significant except in desert environments, and attenuation by rain ( rain fade ) is a serious problem even over short distances."" Due to atmospheric drag, satellites do not usually orbit below 300 km (190 mi)."Of note is the fact that 5G also utilizes the same frequency ranges that 3G and 4G uses as well as EHF ranges. I am not a 5G engineer so I cannot speak to the technical specifications at a protocol layer but I would feel comfortable guessing that the utilization of lower bands is for backwards compatibility with equipment already deployed in the field. You won't be able to get Gbit speeds on lower band ranges, but you will still get speeds as good as your best 4G connections so this allows economies to deploy and adapt new technology in segments. This would allow 5G devices to operate on lower band's and remain backwards compatible for pre-existing deployments for maximal compatibility. This is especially true for less developed nations who may have seen large 3G and 4G expenditures and will be slower at upgrading their infrastructure. Many African nations skipped landlines and leapfrogged straight into wireless cellular networks.I find that these conversations usually devolve into simple fears about wireless energy being transmitted and that it is harmful. Yet there is and has always been wireless energy all around us our entire lives. Take Television for example which is broadcasted at 698 MHz and 10,000 watts. 5G broadcasts at 700MHz and 1 watt. Or aeronautical radio navigation frequencies at 960MHz at power ranges between 5-50 watts. Your cellphone will receive @ 1W.Now lets compare that to the Sun shall we? The sun provides 1340W/M² to the top of the atmosphere and about 340W/M² at ground level (on your skin).If you are not afraid of 340W of visible light spectrum energy (which is the closest spectrum to ionizing energy, the energy that actually radiate your cells beneath your skin), then why would you be afraid of 1W at the complete other end of the non-ionizing spectrum?"X-rays and gamma rays have enough energy that during interaction with atoms, they can remove electrons and cause the atom to become charged or ionized. That’s why we refer to these as ionizing radiation."The FDA actually did a meta-analysis on 10 years of Radio Frequencies and Cancer. But a lot of these conspiratorial types hear "FDA" and "CDC" and their brain shuts down. It turns into a big "government conspiracy" and devolves into "who funded these studies! its all collusion between the government and scientists!" crazy talk. So giving them this link may not help you, but here's what you can do.....this meta-study has nearly 300 independent studies cited.Simply go to the citations at the end, look up the title of the study and copy/paste into google scholar/pubmed. If its behind a paywall you can use sci-hub.tw to get the article. Note that the domain changes on sci-hub as its a cat and mouse game avoiding being shut down, so google sci-hub if that domain is down to find a mirror. Then you can post the research directly without a big "FDA" logo on the meta-analysis. So if someone gives you some crap science thats not even peer-reviewed and no details (equipment used, environment tested, controls, etc) simply start hyper linking to them the 100's of studies that are in direct contradiction of the poor science they are posting.I always find it ironic that the same people accusing scientists of being part of a conspiracy will also use scientists work to validate their claims. Yet the 1 scientist that does bad science is right, but the several hundred of thousand good scientists are wrong.The thing that is not talked about in regards to this topic but should be controlled/accounted for is the depletion of the ozone layer within the atmosphere. While we are finally starting to see some healing we still had decades where Ultra-Violet radiation was increased due to ozone-layer depleting chemicals being in an abundance in our atmosphere and reducing its efficacy to protect humans from ionizing radiation wavelengths making it through. I do not have any evidence to cite, but we obviously have been able to measure increased UVB's at ground level because of ozone depletion. Even with a healthy atmosphere we know that the sun causes cancer so with a depleted atmosphere it logically follows that we would be more susceptible.Hope this information is helpful.Other Resources -
