What is 5G?
5G is the fifth and newest generation of mobile connectivity. Its commercial rollout has already begun, with the four major US carriers having begun deployment in 2019. The GSMA estimates that 5G will account for 20% of all global connections by 2025. What’s more, this technological advance is at the heart of many economic and geopolitical issues. But associations and researchers have also warned on the potential risks 5G represents to health and the environment.
Supporters of 5G have made big promises. Compared to 4G, the technology should allow for connection speeds which are 10 to 100 times faster, with minimal latency. These connection speeds are perfect for playing the most demanding of online games and streaming series in the highest quality available without any loading.
Above and beyond that, 5G marks a further step in the development of “Smart cities”, in which all kinds of connected objects communicate between one another. One of the main technologies standing to benefit from 5G is the driverless car. It’s anticipated that the reaction time of self-driving cars will improve to 1 millisecond thanks to 5G, making them smarter and safer.
That’s why this new generation is presented by governments as being a major strategic industrial development.
On the other hand, associations have warned about risks of insomnia, infertility and even cancer. The World Health Organisation does indeed class electromagnetic waves as a possible cause of cancers.
Experts have responded by saying that 5G waves have a length of around 3.5 GHZ, thus smaller than 4G waves. Therefore, they couldn’t cause cell damage, but may still be harmful to skin, eyes, eardrums, nerve endings and blood circulation.
