The influence in our society of mobile phones would have been practically a chimera without the standardization, improvement, and evolution of the protocols of the communications networks and their support by the operators. The first generation 1G, the responsibility of Ericcson with the NMT system, was created in the year 1979. Since then, the evolution has not stopped its course until arriving at the fourth generation or 4G that offered greater security and quality of service.
At this time, its main successor, 5G technology, has come to stay, offering greater performance with theoretical speeds of data transfer down to about 10 Gbps, a remarkable improvement compared to the 75 Mbps of generation previous.
What is 5G technology?
The 5G technology is presented, therefore, as the successor of the 4G generation, maintaining the functions of its predecessors in terms of instant messaging, calls and Internet browsing with the exception that the connection will be much faster, navigating to some not insignificant 5,000 megabits per second.
Faced with such data, it would not be negligible to consider the fact that, for example, if with 4G technology it took us about six minutes to download a two-hour movie, now with 5G technology that time is reduced to the incredible 15 seconds, being twenty times faster. In addition to its impressive degree of Do My Assignment performance, this technology improves the level of latency significantly. 5G technologies are designed to manage all types of traffic with extremely low latency, being thus essential to power portable technologies, home devices or smart cars. In this sense, it is expected that the latency may fall below one millisecond.
At the level of speed, very diverse companies recognized internationally have created test networks and prototypes that are capable of supporting 5G networks. We only have to look at the Swedish company Ericcson to realize that last year managed to reach speeds of up to 5Gbps real, using the standard prior to the definition of the 5G protocol.
What is the 5G network?
The 5G network has been built on the bases already established by the 4G LTE (Long Term Evolution) already configured. As it was specified in previous lines, it will allow sending text messages, surfing the net and making calls with radically higher transfer speed. However, as 5G technology goes far beyond smartphones, including sensors, cars, thermostats, cars, robots, and other technologies.
In the case of cars that are driven autonomously, this technology will involve communication with virtually no interruptions between the car, other vehicles, external sensors and data centers. The frequencies that are higher will have faster speeds and, therefore, greater bandwidth. To do this, wireless companies must install thousands of small towers to incorporate on each light pole, inside each house and, potentially, in each room.
Instead of replacing it completely, 5G technologies will complement this technology, so that in buildings and crowded areas, this innovative technology will provide greater speed, however, when you are driving on the highway, the 4G would be the only alternative, less during a certain time. Although these networks will not be launched by wireless companies until 2020, the fact is that this month 5G technology when an international consortium of wireless networks such as 3GPP came to approve a technology standard for next-generation networks. Once the International Telecommunication Union of the United Nations revises this standard, companies will be able to buy and sell 5G equipment.
5G SIM cards are ready: features and improvements
The new card will be available in the usual physical formats such as MiniSIM, MicroSIM or NanoSIM but also in eSIM format. In addition to improvements in data privacy and global 5G roaming without interruptions, it is the first with extended protection against hacking. The new 5G SIM card will arrive throughout 2019, initially in the second half of this.
The advantages go through the complete anonymity of end-to-end subscriber identities by encryption of the identification data of incorporation, the elimination of possible misuses and compliance with regulations for operators, such as GDPR. As soon as we know about the existence of a 5G SIM, we have been asked if it will be necessary to change SIM to enjoy the 5G networks to the maximum. With the arrival of 4G, we had to ensure that we had compatible SIM cards although at that time the vast majority of customers already had them and only rarely had to proceed with the change.
Now, we have reviewed the latest specifications and there are doubts about whether it will be necessary to change SIM. For example, Ericsson believes that it should be possible to continue using the current SIM (USIM) with 5G networks. The same opinion from China Mobile that ensures that the new 5G networks will not require a change of SIM. Gradually you should be replacing current SIM cards with new SIM cards 5, but not for reasons that go or not work. The SIM alliance believe we can maintain current cards early years, but then change them to enjoy benefits such as increased security, the SIM OTA updates, and improvements to the user experience.
That is, we can connect to 5G networks with current SIMs if nothing changes in the coming months, but it is recommended that operators offer new 5G SIM cards to enjoy all the benefits of this new generation of mobile networks.
