5G stands for fifth-generation cellular wireless, and the initial standards for it were set at the end of 2017. 5G is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks. 5G enables a new kind of network that is designed to connect virtually everyone and everything together including machines, objects, devices and possibly people too.

5G mobile technology promises a ten-fold increase in data transmission rates compared to current 4G networks, which will be achieved by using a higher transmission frequency. The physiological effects of electromagnetic radiation change with frequency, so the advent of 5G triggered a major international review of relevant radiation safety guidelines, for which it’s agreed that there is insufficient data for a meaningful health risk assessment.

“As the frequency goes up, the depth of penetration into biological tissues goes down, so the skin and eyes, rather than the brain, become the main organs of health concern,” Wood says. “The major hurdle is that the power levels involved in mobile and wireless telecommunications are incredibly low, which, at most, produce temperature rises in the tissue of a few tenths of a degree. Picking up unambiguous biological changes is therefore very difficult.”

“Numerous recent scientific publications have shown that EMF affects living organisms at levels well below most international and national guidelines. 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. Damage goes well beyond the human race, as there is growing evidence of harmful effects to both plant and animal life.”

However, it will be important to balance the risk and reward, says a prominent scientist. “Wireless technologies bring enormous benefits, and being over-cautious would potentially deny these benefits to needy communities.” It is important especially in Africa for users to do their own research before buying the so-called advanced 5G devices so as to safegurad their health
