En France, il est prévu que la 5G se déploie sur plusieurs bandes de fréquences : celles déjà utilisées pour les réseaux actuels 2G/3G et 4G (dites "bandes basses") et deux nouvelles bandes jusque-là non attribuées aux réseaux mobiles, celle de 3,5 GHz et celle de 26 GHz.

Les chaînes de la TNT sont de leur côté diffusées sur une bande comprise entre 470 et 800 MHz. Quant au réseau téléphonique, il utilise les fréquences allant de 700 à 2.600 MHz. Dans le cas de la 5G, les opérateurs vont dans un premier temps utiliser la bande comprise entre 3.400 et 3.800 MHz, soit entre 3,4 et 3,8 gigahertz (GHz). La 5G offrira un débit plus important, même s'il demeure difficile d'estimer avec précision le gain pour le consommateur final.

La bande de fréquences des 3,5 GHz (3,4 - 3,8 GHz) est celle qui sera utilisée en priorité pour le réseau mobile 5G. C'est la bande coeur de la 5G. Sur les 400 MHz de largeur de spectre, 310 MHz...

La bande 3,4 ‑ 3,8 GHz constitue la « bande-cœur » de la 5G, dont le déploiement doit permettre d'améliorer la compétitivité des entreprises, de développer l'innovation en France ainsi que de répondre aux attentes des utilisateurs d'accéder à des services mobiles toujours plus performants.

Celui-ci est divisé en bandes de fréquences, qui sont attribuées aux services de radiocommunication de telle sorte que chaque bande ne puisse être utilisée que par des services pouvant coexister. La prise en charge d'un trafic accru et d'un débit plus élevé dont la 5G a impérativement besoin nécessitera des technologies beaucoup plus efficaces sur le plan spectral, ainsi que des ...

Les fréquences déjà utilisées par les précédentes générations de téléphonie mobile (2G, 3G, 4G) seront exploitées, ainsi que deux nouvelles bandes de fréquences : dans un premier temps, la bande 3,5 GHz pour la couverture en téléphonie mobile 5G dans des zones géographiques étendues, puis les années suivantes, la bande 26 GHz pour la communication entre des objets connectés ...

Il y a un discours qu'on entend souvent des équipementiers télécoms qui est de dire que pour faire de la bonne 5G il faudrait une largeur de spectre de 80 MHz par opérateur » sur la bande des 3,5 GHz. Avec quatre grands opérateurs, le total monterait à 320 MHz. Or, dans le cas du choix des bandes de garde, cette limite n'est pas atteinte, alors qu'elle l'est tout juste avec la synchronisation.

"The truth about mobile phone and wireless radiation: what we know, what we need to find out, and what you can do now"
Presented by Dr Devra Davis, Visiting Professor of Medicine at the Hebrew University Hadassah Medical School, and Visiting Professor of Medicine at Ondokuz Mayis University, Turkey.
The Lecture
What are the health effects of mobile phones and wireless radiation? While Australia has led the world in safety standards, including compulsory seat-belt legislation, plain packaging on cigarettes, and product and food disclosure legislation, it falls behind in addressing the significant issues associated with mobile phone use. In this Dean’s Lecture, epidemiologist and electromagnetic radiation expert, Dr Devra Davis, will outline the evolution of the mobile phone and smartphone, and provide a background to the current 19 year old radiation safety standards (SAR), policy developments and international legislation. New global studies on the health consequences of mobile/wireless radiation will be presented, including children’s exposure and risks.
The Speaker
Dr Devra Davis is an internationally recognised expert on electromagnetic radiation from mobile phones and other wireless transmitting devices. She is currently the Visiting Professor of Medicine at the Hebrew University Hadassah Medical School, and Visiting Professor of Medicine at Ondokuz Mayis University, Turkey. Dr Davis was Founding Director of the Center for Environmental Oncology at The University of Pittsburgh Cancer Institute — the first institute of its kind in the world, to examine the environmental factors that contribute to the majority of cases of cancer.
In 2007, Dr Devra Davis founded nonprofit Environmental Health Trust to provide basic research and education about environmental health hazards. Dr Davis served as the President Clinton appointee to the Chemical Safety and Hazard Investigation Board in the U.S.A. from 1994–1999, an independent executive branch agency that investigates, prevents and mitigates chemical accidents.
As the former Senior Advisor to the Assistant Secretary for Health in the Department of Health and Human Services, she has counseled leading officials in the United States, United Nations, European Environment Agency, Pan American Health Organization, World Health Organization, and World Bank.
Dr Davis holds a B.S. in physiological psychology and an M.A. in sociology from the University of Pittsburgh, 1967. She completed a PhD in science studies at the University of Chicago as a Danforth Foundation Graduate Fellow, 1972 and a M.P.H. in epidemiology at the Johns Hopkins University as a Senior National Cancer Institute Post-Doctoral Fellow, 1982. She has authored more than 200 publications and has been published in Lancet and Journal of the American Medical Association as well as the Scientific American and the New York Times.
Dr Devra Davis is an internationally recognised expert on electromagnetic radiation from mobile phones and other wireless transmitting devices.

01:12 let me just introduce dr. Deborah Davis who doesn't probably need an awful lot of introduction the dr. Deborah Davis is a visiting professor of medicine at the Hebrew university Hadassah medical school and also in Turkey at under Kuzma University
she's an expert studying doctor magnetic radiation for mobile phones and wireless transmitting devices at present she was the founding director of the center for environmental oncology which was the first such Center in the world and was established University of Pittsburgh Cancer Institute and he was linking looking at the environmental factors that contribute to cancers in 2007 she founded a non-profit environmental health trust to provide basic research and education about environmental impact on health hazard she served as President Clinton's appointee on the Chemical Safety and hazard Investigation Board in the United States from 94 to 99 there was an independent executive branch of the government that ...

the cumulative integrative dose under the curve over a lifetime exposure that looks to be biologically important now exposure is the kind of funny thing there's a rather widely distributed paper by Ken Foster and CK Cho that said that the exposure of an adult and the exposure of a child is identical and therefore there's no real difference in how the radiation might be affecting them well let me ...

motility this is a measure of the mitochondrial DNA damage they have three times as much damage on their DNA if they have been exposed to mobile phone radiation as compared to controls and now the issue is why does it take a half a billion sperm to make just one healthy baby it takes a lot of sperm to make a healthy baby the answer is because sperm don't know how to ask for directions but they are easy to study and these research has been done in India in the United States at the Cleveland Clinic and around the world so many different studies have been done on sperm damage at OCA with mobile phone radiation that in the seventh edition of the textbook biostatistics in medicine Stanton glance concludes that the evidence linking mobile phone radiation to sperm damage is causal meaning there clearly is a cause of damage to sperm for mobile phone radiation ...

in male fertility who started to treat men at infertility clinics and noticed that this was a major contributor to their fertility problems now experimental studies have been done also in India to confirm this kind of damage not just looking at prenatal exposure or early life exposure but taking middle aged rats 70 day old male rats that's middle age for rat and exposing them to hours a day for 45 days to a computer-generated mo phone signal and those results show lower testosterone which is a very important hormone for a male men and women both have testosterone men just need a lot more of it and also increases of DNA damage as measured by certain enzymes and the and the offspring had lower fertility and this is just to show you this is a normal test this you see the boundaries the cell wall looks very nice and this is after microwave radiation exposure ...

il ne s'agit pas de la 5G en particulier mais des ondes EM en général, l'approche d'une mesure immédiate (instantanée) n'est pas une bonne approche, plusieurs effets ne se manifestent qu'avec le temps...regardez cette vidéo et vous comprendrez - 0 - 1 - 0
