A writer known for his ideas on the digital revolution said that “technology feeds itself. Technology makes more technology possible. ” Without a doubt, it is a sentence that perfectly describes the evolution that connectivity has experienced from 1G to 5G, highlighting what will be one of the great technological transformations in history and that will forever change our navigation and mobile experience.

How did we get here? An evolution at different speeds

• 5G has gone from being a chimera to a reality after a constant evolution over time.
• Looking back, everything has a beginning, and in this case can date at the end of the decade of the 70, when a new connectivity standard came to the world, 1G. Specifically, it was in Tokyo that the first analog mobile phone system emerged. Fruit of its appearance is the first mobile phone and, therefore, the first calls without the need for a cable. Of course, there was no data transmission either.
• Sometime later, specifically in the early 1990s, there was the advance from 1G to 2G, that is, from analog to digital telephony
  Although it now seems incredible due to the date we are talking about, it also made it possible to browse optimized websites from the mobile phone.
• The main qualitative leap in this evolution occurred with 3G, a standard that emerged due to the increasing demand for data transmission. Its birth could be dated back to 2001 first 3G roaming call with Japan. In 2003, in the UK, the launch of a new version of EDGE connectivity allowed speeds of up to 2 Mbps to be achieved. Transferring it to terms of user experience, it meant that from the mobile you could access full versions of the websites, navigate smoothly and even consume online videos on platforms such as YouTube or Vimeo. It also meant the generalization of smartphones.
• The one that until today was the last step on this path is the 4G and the LTE (Long-Term Evolution connectivity) standard that we currently enjoy. It emerged in 2009 and improves the transmission power of 3G standards, reaching speeds of up to 100 Mbps in motion and 1Gbps at rest, making it possible to process more information and, for example, be able to watch 4K videos.

Increased data transmission, more speed, and reduced latency, among 5G improvements

Based on the fact that 2020 is the horizon for the final takeoff of 5G technology, the truth is that we are already in a position to know first-hand what changes it will mean for the user:

• More data: the capacity of the network to support data transmission is increased again. It is expected that traffic will be multiplied by at least 10, although it could reach up to 100 times more connected devices.
• More speed: between 2 and 20 Gbps, which will completely change telephony as we know it today, redefining our experience on the Internet when browsing on mobile. And it is that these speeds will exceed data download to current fiber optic networks.
• Lower latency: that is, less time in the execution of an order by a device once the signal has been sent to it. This response time will be, specifically, between 1 and 10 milliseconds (4G has about 40 milliseconds) and will mean, in practice, almost real-time performance that will reduce application response times, but also enjoy games in virtual reality, that a surgeon can operate a patient remotely, operate machinery from a computer, driverless vehicles or the earliest detection of natural disasters, to give some examples.
• IoT: although with 4G it is already possible to connect devices to each other, the reduction in latency and connection capacity offered by 5G networks will be the definitive boost for the Internet of Things, giving rise to a world in which home appliances, wearables, Cars, computers, and terminals, in general, will be fully connected, contributing definitively to the development of Smart Cities.

One of the latent concerns of 5G is security. In this sense, the increase in connected devices and the transmission of data make privacy and security a priority for the 3GPP (3rd Generation Partnership Project, the international organization for the standardization of telecommunications) and the GSMA association. Both entities are defining the standards of the SEPP (Security Edge Protection Proxy) that will act as “guardian” of 5G networks, providing confidentiality and protection to the data transmitted on those networks. This technology will be available before fifth-generation networks are connected.

5G technology will reach our devices in the year 2020 and will be a revolution that will change our world towards a society with millions of connected objects and almost immediate response times.

What is 5G & What Changes Will Occur With Respect to 4G

As we already said the definition of 5G and it refers to the fifth generation of mobile technology, a new standard in telecommunications that will replace the current 4G.

Comparing to 4G?

Currently, your mobile device is connected through the 4G standard, whose latest evolution has been the 4G LTE with a data transmission rate of 100 megabits in motion and up to one gigabit at rest (provided that the connection is ideal). When we talk about 5G we mean a data transmission speed up to 1,000 times higher than what we currently know.

Steps Taken For 5G Implementation?

The importance of the implementation of 5G goes beyond the speed of response or connection of mobile phones and is a real revolution that will affect our urban environment, through the Smart City, and the way we have of relating, doing business or exchanging data.

For this, the European Union has created a private-public working group called 5G PPP in which the main telephone operators are present together with representatives of the European Commission. 

GSM to 5G: The Changes in the Mobile World

In recent years the evolution of the connection and data transmission of our mobile terminals has not stopped evolving and improving the way we communicate. Do you know what the letters that appear on your mobile mean when you connect to a data rate? Let’s review the latest changes in mobile transmission.

• GSM was responsible for the first connections and mobile data transmission. Thanks to this standard we could send up to 10 SMS per minute.
• GRSM the evolution came with the GRSM that extended the GSM bandwidth and allowed us to have a connection speed of up to 114 Kb per second.
• Edge or EGPRS: on many occasions, you can see it on the screen of your mobile summarized in the letter E, we talk about an improved GPRS that extends up to 384 Kb the connection speed of your mobile phone.
• 3G: it is the first major revolution in the world of mobile connection and opens the door to smartphones as we understand them in recent years. The connection speed reaches up to 2 megabits per second, an obvious improvement that allows us to start surfing the Internet through our mobile terminals.
• H +: You can also see it on many occasions on the screen of your mobile (especially if you are on the road) and it is an improvement of the technical conditions of 3G since it extends up to 14 megabits the connection speed.
• 4G: The evolution of 3G comes from the hand of 4G whose figures are summarized in 100 megabits in motion and up to one gigabit at rest. In recent years a new evolution has been reached, the 4G LTE that prepares the ground for the arrival of 5G.

The Revolution That 5G will Bring

To understand the changes that the 5G standard will bring, it is best to highlight the data that marks this impending revolution in mobile technology:

• The data transmission speed will reach 10 Gigabits per second, between 100 and 1,000 times higher than that of 4G.
• The 5G will reduce the latency period (time that passes from being transmitted from a mobile terminal until it reaches its destination) that will go from the current 50 milliseconds to 1 millisecond.
• 5G technology will allow the interconnection of 50,000 million connected objects (Internet of Things).
• Thanks to 5G you can download a movie in less than 10 seconds.
• It is estimated that the first 5G devices will be operational throughout the 2019-2020 period.
• 5G technology will generate energy savings of 90% over current consumption, according to EU data.
• The investment of the EU 5G PPP working group is 700 million euros.
• The private part of the 5G PPP is made up of some 800 companies from all technology sectors in Europe.
• The implementation of 5G will involve the installation of tens of thousands of micro-antennas or small cells that will replace the large telephone towers and make the current network much denser and connected.

The Digital Transformation With 5G

With the arrival of 5G, we are talking about much more than a better chance in our connection speed and data transmission. Experts agree that more than an evolution we are talking about a revolution that will turn our world into hyperconnected and our cities in an intelligent environment that will transmit and receive millions of data instantly. What are the axes of this 5G revolution and why is it indispensable in digital transformation?

• Smart City: millions of sensors and connected devices that receive and send information from their users and administrations to achieve total interaction and an improvement in the quality of life of their inhabitants. Without 5G, Smart City cannot respond to all this information flow. Do you remember the keys to a Smart City? 
• Industry 4.0: Without the speed of data transmission that 5G will provide, the complete development of the concept of Connected Industry or Industry 4.0 is currently laying its foundations and that will bring about these important changes in the current manufacturing processes that can be made Summarize in these keys.
• Internet of Things: Together with these two concepts is the development of the Internet of Things. Without a speed of data transmission and instantaneous response time, the concept of the Internet of Things cannot develop in its entirety nor generate the expected transformation in our way of relating to objects.
• Big Data: millions of data instantly that report to millions of other data that are going to be indispensable for the operation of both our cities, as well as the industrial sector or the private company and that cannot be understood without the technology and possibilities offered 5G.

Conclusion

Hope the whole world will experience the advantages that 5G will bring and make human life as simple as possible with the help of 5G technology
