Oxygen Absorption
Their interest in this frequency band stems from a phenomenon of nature: the oxygen molecule (O2) absorbs electromagnetic energy at 60 GHz like a piece of food in a microwave oven (see Figure 2).5G technologies have to satisfy ITU IMT-2020 requirements and/or 3GPP Release 15, while IMT-2020 specifies data rates of 20 Gbit/s, 5G speed in sub-6 GHz bands is similar to 4G. So it's true that 5G will operate beyond 60 GHz but in millimeter wave.
Most cellular “5G frequencies” (higher frequencies) cannot even penetrate a piece of glass. 95% of cellular 5G frequencies are up to 100x worse at penetrating walls, glass, and buildings.
High-band 5G uses frequencies of 25 - 39 GHz, near the bottom of the millimeter wave band, to achieve download speeds of 1 - 3 gigabits per second (Gbps), comparable to cable internet.
So far, there is no consistent evidence that WiFi routers or WiFi-powered devices increase cancer risk. Despite low-frequency EMFs being classified as possibly carcinogenic, researchers have not observed a direct connection between these devices and cancer.
WiFi of any kind does emit RF, or EMF, radiation. This radiation in large quantities over long periods of time can cause harm to the body. However, 5 GHz WiFi isn't absolutely more dangerous than 2.4 GHz WiFi, it all depends on how close to the emitting router you are and what devices you're using.
Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans.
Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload.
It is safe to sleep next to a wireless router as it produces radio waves that, unlike X-rays or gamma rays, do not break chemical bonds or cause ionisation in humans. These waves also deteriorate rapidly, losing their strength as they travel away from the router.

Wifi as an increased cancer risk
No, it isn't. Wi-fi routers are weaker transmitters even than mobile phone masts, and users sit away from them. The level of energy produced by a Wi-Fi router is very low, far too low to be able to disrupt DNA, so there is no mechanism for it to be carcinogenic.Earlier this year, a rodent study found heavy exposures to cell phone radiation increased rats' risks for some brain and heart tumors. More rodent research has tied high levels of Wi-Fi and cell exposure to hormonal shifts and oxidative stress—the kind of shifts that could promote cancer or brain diseases.
Only a few other countries — Japan, Australia and New Zealand — have barred Huawei 5G deals; many world powers remain undecided. American officials cast the race to 5G as a quintessential national security competition, rather than a commercial one.
Conclusions. Over-exposure to any man made technologies could potentially be harmful and 5G is not unique. However, 5G is no more or less safe compared to 4G or 3G or even your home wifi. 5G did not cause Coronavirus COVID-19 and it did not contribute to the spread of the pandemic in any way.

China. China has launched its 5G national network and started commercial operation on 1 November 2019.
Effects include increased cancer risk, cellular stress, increase in harmful free radicals, genetic damages, structural and functional changes of the reproductive system, learning and memory deficits, neurological disorders, and negative impacts on general well-being in humans.
4G-enabled devices connect to the Internet though their provider's cellularconnection. Fortunately, data being sent via 4G is encrypted, making 4G safer than public Wi-Fi.
South Korea, China, and the United States are the countries that lead the world in building and deploying 5G technology. Telecommunications operators around the world—including AT&T Inc., KT Corp, and China Mobile—have been racing to build the fifth-generation (5G) of wireless technology.
What's the difference between 2.4 GHz and 5 GHz WiFi?
| Standard | Frequency | Theoretical Distance |
|---|
| 802.11g | 2.4Ghz | 125 ft |
| 802.11n | 2.4Ghz | 820 ft |
| 802.11n | 5Ghz | 460 ft |
| 802.11ac | 5Ghz | up to 820 ft (amplified) |
5G Did Not Cause A Mass Bird Die-off
While researchers have speculated that cell frequencies may affect how migratory birds navigate, it is not to a harmful degree. So far, 5G has not been found to have any directly harmful impacts on birds.
