What is the 5G you are asking? It has been almost ten years, but 5G is finally turning into reality. After years of expectation, companies like AT&T and Verizon give customers a clear idea of ​​what their next-generation mobile networks will be capable of.

However, there seems to be more questions than answers. Some people wonder what 5G is, and whether they will ever appear in their city, while others are more interested in 5G smartphones. You have questions, we have answers. Here’s everything you need to know about 5G.

What is 5G?

5G is a new generation of mobile broadband network that will eventually replace or at least extend your current 4G LTE connection. Telephone companies move to a new wireless standard about every 10 years. Approximately 10 years ago, the fourth generation of networks (4G) came, which was much faster and stronger in terms of reliability than its predecessor 3G.

With 5G comes an exponentially faster download and upload speed. Latency, the time it takes devices to communicate with wireless networks, will also dramatically decrease.

How fast is 5G connection?

5G will offer much faster data transfer than its predecessors. The maximum transfer rate can reach 20Gbps downlink and 10 Gbps uplink per mobile base station. This is not the speed you actually achieve (unless you have a dedicated connection) – it is the speed that is shared with all users on the network.

While all this sounds great, the actual speed will not be the same as defined above. The real specifications for the general user will be “only” 100 Mbps when downloading and 50 Mbps when uploading data.

Latency, that is, the time it takes to move from A to B, should be only 4 milliseconds. Of course, in perfect conditions.

So all this means that in some cases the 5G connection will be really faster than Wi-Fi.

Is 5G dangerous or isn’t?

The reason why many people condemn 5G is the extremely high frequency that 5G uses. Frequency between 30 GHz to 300 GHz. Due to the high frequency characteristics of this network, the waves do not travel as far as 4G connections.

Because of this, signal transmitting antennas must be placed closer to each other to provide pure 5G reception without any interruption. It is for this reason that the antennas numbers will increase and we are not talking about a few other antennas, but much more! However, these are not large towers, but low-profile antennas that occupy only a fraction of the space of a conventional tower.

Some people believe that daily exposure to radiation is harmful to health. Belgian doctors call it “highly dangerous” and say that 5G causes headaches, chronic fatigue, concentration disturbances and even cancer.

“Just because scientists couldn’t prove that radiation is harmful, does not mean it is safe. No one died from it, so far, but we don’t know the effects in the long term.” said Professor Guy Vandenbosch, a radiation expert at KU Leuven University.

However, the heating of 5G is negligible. “Someone’s brains heat up far more when walking in the sun than holding a cell phone to their ear. Additionally, we have to admit that wireless technology already saved many human lives.” said Professor Vandenbosch.
