First of all we need to know what ”G” means.
As simple as it sounds, “G” come from “generation” in wireless technology. Every new generation should be faster, more secure, and more stable. Stability is a very difficult factor to master. 1G technology has not been used to identify wireless networks.
On paper, a 4G connection would allow speeds that are close to 1 Gigabit per second, if you stay at a fixed point. From this point of view, the speed promised by 4G technology is still difficult to achieve. Perhaps with the appearance of 5G we can reach the true potential of 4G.
What are the standards for each generation?
1G – It’s a term that has never been widely used until 2G technology has been available. This was the first technology used by mobile phones. 1G technology allowed you to make a phone call and nothing more.
2G – The second generation for mobile phones came with a number of improvements, including the ability to deliver text messages.
3G – 3G technology has set a number of standards that we all know and love. This has given us the ability to browse the internet to check our email to download videos and send photos using a mobile phone today. Besides, it gave us the freedom to leave voice messages. 3G technology is capable of supporting speeds up to 2 MB per second. Without the development of this technology, smartphones of today would not have been achieved, it would not have been a support they could rely on.
4G – The fourth generation of these technologies could be described in one word, namely, fast. If we were to be a tech, this assumes the fourth-generation protocol for mobile data but if you ask a 4G user will tell you everything is about speed. This theoretically allows speeds of at least 100 MB per second and can reach up to 1 GB per second. As this technology is likely to grow, we will probably reach those speeds, most of which are still based on 3G-enabled stations.
4G LTE – 4G Long Term Evolution Technology is a 4G upgraded but does not meet the 4G technology standards. However, it is faster and the difference between the two is known.
First it was 3G, then we entered the 4G era, and in these years we are heading with rapid steps towards the 5G era. It is true that the speed of mobile Internet in the 5G case is considerably higher, but this advantage is countered by the higher risks to human health.
The whole issue is that the 5G network will use the higher frequency bands that have not been considered as presently possible at frequencies of 24 to 100 GHz which have not been tested. Also, the new frequencies will need new antennas to amplify the signals, which means we will see a huge antenna deployment everywhere.
In the US, this year (2017), tests for 5G will begin testing by large corporations such as Verizon and ATT, with the first commercial launch scheduled to begin in 2020.
But how safe will be these 5G communications for human health?
The authorities, as always, will say there will be no major health problems for humans and animals, but remember that 40-50 years ago they were saying the same thing about lead paint or smoking, as today we find out that all these are extremely carcinogenic to the body.
However, the US National Toxicology Program has conducted a $ 25 million governmental study, and concluded that wireless radiation can cause cancer. And many other studies have come to the same conclusion. Even large telecom corporations, by providing legal compensation to wireless technology victims (most cancer sufferers) in the various open processes, show that they implicitly recognize that there is a serious problem with new technologies such as 3G or 4G.
