The acronyms used to refer to the fifth generation of wireless connections (5g) intended for mobile devices will be key to take the next step in the evolution of technology. The main question is … what’s the 5G for? In order to begin to understand its impact, it is necessary to keep in mind the two main improvements with respect to 4G: a higher speed, up to 5 Gaps in several tests (although in others it is even greater), and a latency, Delay in milliseconds that takes the information to arrive, much lower, whose figures vary somewhat more depending on who is pronounced, but that can be rounded in about 5 milliseconds.
Some of the problems that will solve the 5G are those that drag the 4G, such as mobile coverage: traveling by car or train currently involves a constant transfer of signal from one antenna to another, whose effects will soften with the 5G, you will get a more constant and regular signal. Some studies and projections place this capacity at around 10 Tbsp. per square kilometer, and with a density much higher than the present one, of approximately one million nodes per square kilometer.
And, according to the information that the operators handle, the deployment will be simpler and faster than in the case of 3G or 4G, since they have learned from previous processes and the antennas can cover more area and more devices for each one of them.
Main areas that will benefit from 5G
The V2V communication (vehicle to vehicle) is one of the protagonists, supported among others by Ericsson, which will allow the cars to communicate with each other. For example, with videos that allow you to see through other vehicles, or send relevant information such as when a car is braking abruptly at high speed, when it has suffered a breakdown and may appear problems, etc. That’s where the decrease in latency is decisive: a few milliseconds or so in the communication between two endangered vehicles can make the difference between avoiding an accident, and possibly saving lives or not. Or without reaching such dramatic levels, it would allow the possibility of slowing down before reaching a congested intersection.

Internet of things
The 5G is also not understood without talking about the Internet of things, which in turn is also not understood without talking about ESIM, the virtual replacement of SIM cards. And about it, Intel already gave some good brushstrokes in its direct approach to the future. In smartphones or tablets will allow dispensing with a physical component and moving parts, which can be used to continue miniaturizing or to increase the battery. But in everyday objects, some tiny ones, it is possible to connect them, to make them intelligent and able to communicate: vases, pillows, parking sensors, washing machines, toothbrushes, slippers, lamps, etc. As this progresses, we will have a large number of connected devices sending small amounts of information on a regular basis, which would require a new low bandwidth protocol. Only with the 4G would be very complicated, especially as the number of devices increases. With the 5G opens the door to the Internet era of things.
Truly wireless internet
“The 5G will allow the Internet to be completely wireless, ” said Steve Mollenkopf, CEO of Qualcomm. That phrase refers to a future in which cables will not be needed to ensure high-speed, almost instantaneous and stable connections. In this way, also opens a new stage for the communication between smartphones like the M2M (machine to machine). On the other hand, it is estimated that there will be about 50 billion connected devices by 2020 that could benefit from 5G, according to Intel.
Online Video Games
More areas potentially benefited by the arrival of 5G: video games online or directly in the cloud. Currently, it is necessary to download a video game to play, but some companies have already tried to bet on a completely online system. The 5G will allow, due to its very high speed and low latency, to play directly console games without having to download them with the possibility of streaming and access the online mode directly from a mobile network. So it would be easier to think of video games with desktop power, but that can be played from a smartphone since the processing would not have to be done on the device itself, but in the cloud. On the phone would arrive the image in near real time of a game.
Another important area: health. Again, latency is the main character. With the reach and speed of the 5G will facilitate wireless and remote communication between advanced medical instruments and hospitals of inferior equipment. This scenario, combined with the development of the eHealth sector, or technology focused on the medical sector with a special emphasis on Big Data, can be defined as one of the trends in the future of interconnected medicine.
The current challenge of 5G
For now, the main challenge is to reach a closed standard; We must understand that this is a project in development, so negotiations between government agencies, operators and companies have not yet reached a common ground. But if the deadlines are met, and despite the intense work involved, and no one seems to have the slightest intention of not doing so, by 2020, the date indicated by all, we will see the first commercial applications, deployment, and development of the 5G.
