Concerns have surfaced about 5G being bad for your health and dangerous for air travel. Some concerns remain around health while measures have been taken to address air safety concerns. Most authoritative sources suggest 5G technology is generally safe but specific items of concern still exist.
The World Health Organization (WHO) and others are studying the potential health hazards associated with exposure to the radio and electromagnetic used by 5G. The FCC asserts that the general public encounters extremely low electromagnetic frequencies, insufficient to result in significant tissue temperature elevation. It has defined radio frequency energy levels that it believes to be safe. 5G technology is expected to comply. Yet in congested city areas with a high concentration of 5G signals it’s not known yet if detriment will eventually be detected from exposure.
Perhaps the most profound warning lies in the fact that 3,500 physicians in preventive medicine, toxicology and other specialties came out against 5G because of exposure to nonionizing radiation. Nonionizing radiation exists in nature, so you can’t avoid it completely. While it can’t change atoms or damage DNA it can cause atoms to vibrate and heat up to dangerous levels. It travels at the speed of light in waves comprising electric and magnetic fields (EMF). Non-ionizing radiation is emitted by microwaves (in low doses) by visible light, by lightning, and by the Earth’s own electro-magnetic fields. The strength of the radiation determines whether it has a detrimental impact on the eyes and other areas of the body. Bottom line: more study is needed regarding the impact of 5G signals on the body.
As of now, the impact of 5G on cognitive abilities remains unexplored. Some investigations on EMFs from different sources present mixed conclusions about their influence on cognitive processes. In 2011, the International Agency for Research on Cancer (IARC) categorized EMFs as having a potential cancer risk for humans. While numerous investigations have delved into the possible connection between EMFs and brain tumors, their outcomes haven't been consistent. Further studies are essential to comprehend the specific effects of 5G on human cells and any potential cancer correlations.
5G employs radio waves (RFs) that surpass the frequency levels of earlier wireless communication systems like 4G and 3G. Electromagnetic fields (EMFs) represent zones of energy produced by electromagnetic emissions. These fields can be categorized into ionizing and non-ionizing types. 5G functions at dual frequency levels, with the peak range spanning from 24.25 GHz to 52.6 GHz. Notably, the threshold where electromagnetic emissions begin to ionize and pose risks is around 3 million GHz, a level significantly higher than 5G's range.
Although high doses of ionizing radiation might be associated with cancer, there's no conclusive evidence linking non-ionizing radiation to the disease. The Food and Drug Administration's experts maintain that the existing radiofrequency energy cap set by the FCC is deemed safe for the general populace.
However, there have been reservations expressed by some specialists regarding 5G. In 2017, an appeal was initiated to halt the introduction of 5G in the EU due to potential cancer concerns. Among the apprehensions are the insufficient duration for thorough 5G safety evaluations and the implications of having 5G hubs densely packed in urban areas.
5G is the newest generation of cellular network technology designed to be more reliable and produce faster speeds, lower latency and increased network capacity. Here’s how:
5G operates on a new high-frequency spectrum known as millimeter wave (mmWave), which encompasses wavelengths between 30 GHz and 300 GHz. Owing to the characteristics of mmWave, including its limited transmission range, new small-cell base antennas are integrated into existing cellular towers to facilitate 5G signal transmission. These additions can be layered in to the current infrastructure. 5G is designed to offer maximum of 20 Gbps and a minimum of 1 Gbps. However, there are different types of 5G (low-band, mid-band, and high-band) with varying speeds. For instance, high-band 5G (mmWave) can achieve speeds of 1+ Gbps.
In essence, while 4G LTE brought significant speed and connectivity improvements over 3G, 5G is set to revolutionize mobile communication with even faster speeds, lower latency, and the ability to connect a vast number of devices simultaneously. But it’s not without the potential to be a hazard.
Both 5G technology and the radio altimeters in aircraft use C-band frequencies. Altimeters are vital in that they calculate the altitude of an aircraft and connect to other critical systems. Therefore, the Federal Aviation Administration (FAA) and other aviation authorities worldwide have imposed restrictions on flight operations that use certain radio altimeter equipment near 5G networks. The FAA required certain regional aircraft to install radio frequency filters by the end of 2022 to counteract interference, and has worked with 5G providers on voluntary mitigations in some key airports. Most of the required work was completed in 2023 and makers of radio altimeters have designed retrofit filters to prevent interference.
Concerns over cybersecurity will exist today, tomorrow, and for the foreseeable future. The U.S. government is concerned about bad actors slipping malicious software and hardware into the 5G ecosystem. Additionally, the vast quantity of information consumed and processed by 5G opens the door for mistakes. These concerns are a fact of life not only for 5G but for technology at large.
