Pros and Cons of 5G explained.
The infrastructure needed for 5G is expensive and difficult to install. In order for 5G to become widespread and accessible to everybody, it would require new towers supporting massive MIMO (multiple-input and multiple-output), additional base stations, and new devices supporting 5G technology.
This process is going to be slow and will be introduced heterogeneously across different regions because of the different laws and regulations existing in every region.
Current phones who support LTE will obviously not support 5G because devices that do support 5G need more than one antenna. In practice, these devices need four to five antennas and a modem like the X50 from Qualcomm which would make the phones bulky and uncomfortable for usage.
The initial devices and data plans for 5G are expected to be quite expensive. Although this is the case for any new technology, with smartphones already costing up to $1000, increasing the price, even more, puts it out of reach for even premium users.
The environmental impact
There are studies that show that there is a significant impact done by millimeter waves on the health of birds and other animals. It also talks about the ecological imbalance that 5G will bring.
The effect on human health
This is a highly controversial and highly debated topic and at the same time one of the most important. Typically, those radio waves which have a frequency of around 70 million GHz or more are called ionizing radiation.
Ionizing radiation waves have the power of causing DNA damage and eventually leading to cancer. The waves that are going to be used for 5G have a mere 60GHz which would mean that it is a million times less powerful than ionizing radiation. That means that if 5G waves cause cancer, so should visible light.
It’s worth mentioning that none of these studies are conclusive and as an intelligent person would say, “absence of evidence doesn't mean the evidence of absence”.
So, will 5G affect our health?
The true answer is “we don’t know, yet”.
One of the most important advantages people pay attention to is the speed. With 3G you will be able to download an average movie in about 25 hours, with 4G that would be less than 10 minutes, and with 5G — less than four seconds.
The theoretical maximum speed of 5G would be 20 Gigabits per second which is 20 times faster than Google Fiber (supposedly the faster WiFi in the US).
5G is also supposed to solve the problem of latency which is the delay between commands and responses from the server. This is also called “response time” and scientists are working on Low Earth Orbit satellites (LEO’s) which can help us achieve this.
5G would have 50 times faster response time than 4G and this is particularly important in machineries like self-driving cars. Even more important is in the health field where doctors could perform real-time surgeries without any noticeable latency.
