This Week in Tech: What is 5G?

Each week, Nico and Nico explain the latest and greatest developments in technology.


5G is the fifth generation of wireless communication standards. First there was 2G used for the earliest wireless telephone calls. Then was 3G which was the first wireless communication signal which made it possible to surf the internet on a smartphone. The last one made before the 5G was the 4G the

speeds of which made it possible to enable video streaming and an entire storage of various apps by giving it a reliable connectivity to the internet.


Now the next wireless communication standards will be 5G which is one of the most eagerly awaited developments in technology so far. Its gigabit speed is supposed to allow you to download full-length movies in just a matter of seconds. One of the major drawbacks of using a 5G network is that it hasn’t reached its full potential yet.


Things that will happen once 5G starts being used internationally:


Video streaming is expected to be the major use for 5G. In a survey, 78% of people expect to increase their video streaming habit once 5G arrives at the market.

Businesses will evolve rapidly in a short space of time due to the speed at which communication will be allowed to go.


One of the worries about 5G is whether it may be able to go through walls. That is the main worry since 5G uses a very high frequency to reach its potential. However a higher frequency means a lower distance in range.


The 3rd Generation Partnership Project, which is the company which creates the rules for wireless connectivity, recently decreed that 4G is allowed to coexist with 5G once its created. Adding to it the new standards stated that the implementation of 5G in a company requires the company bringing a new device to the market. This new device is said to be able to reach a speed of 1Gbps( Gigabits per second) and at its climax reach 10Gbps which could allow you to download a film in a matter of seconds.


Now...... How 5g works is really complex and I personally find it very confusing and difficult to understand, yet here's a more simplified explanations of the frequencies 5g can operate on; sub-6 GHz and millimeter wave (20-60 GHz). One of the main problems discussed earlier about the problem with using high frequencies is that for example a millimeter wave use such a high frequency that it cannot even pass through a window, meaning the device which uses this wave will have to be extremely close to the operator.
