Reflections on the 5G

Starting from a press indiscretion according to which the insertion of the announcement on the assignment of frequencies for 5G transmission in the budget law is being studied. Target least two billion.

The frequencies that will be tendered: are the frequencies in the so-called "pioneer" bands (according to the definition of the Radio spectrum policy group): 700 Mhz (occupied by broadcasters), 24.25-27.5 Ghz, 3.4-3.8 Ghz (the part 3.4-3.6 currently assigned to Defense and leaves until 2022 to operators like Tim, Tiscali and Linkem. In 3.6-3.8 there are around 100 Mhz free, the rest are occupied by Rai radio links).

What is 5G

5G is the new standard for mobile communication: it ensures a very high download and upload speed and allows you to interact with IoT devices

An ever faster connection within everyone's reach. This is the goal of the Next Generation Mobile Networks Alliance, or the association of operators, sellers, manufacturers and research institutes operating in the mobile telephony sector. And the new standard for 5G communication goes in this direction: increase user speed and improve service quality.

Although many still do not have the ability to use the 4G LTE connection, operators are already working on the next standard. According to the road map provided by the operators, 5G should officially go into operation by 2020, but many are accelerating the work on architectures to offer a super fast connection a few months before the established date. Thanks to 5G, users can have extremely high download speeds and very low latency at any time, or the system response time to user requests, in this case, eg, the opening of websites.

Because it is called 5G

5G simply stands for fifth generation and means the set of requirements for a certain communication standard. The history of communication standards starts in 1991 with 2G, developed to improve the quality of mobile telephony. 3G also came with mobile data connectivity, with the possibility to also watch TV programs. 4G was developed to improve IP telephony (VoIP) and cloud computing. The 5G, instead, it is the communication standard designed for the Internet of Things. With more and more devices present inside our homes, you need to have a much faster connection to interact with these new tools. 5G is primarily designed for smart home and industry 4.0

What will change with 5G

The characteristic of 5G that will differentiate it from previous communication standards is the connection speed. According to the operators, 5G should be among the 100 the 1000 times faster than 4G LTE. But to be sure it is necessary to establish common standards for all companies and for the moment these rules are still in an embryonic phase. The Next Generation Mobile Networks Alliance has only established some requirements that the 5G connection must have: data rates of tens of megabits per second for thousands of users, people working on the same floor will need to be connected to at least one gigabit per second, spectral efficiency improved compared to 4G, extended coverage and reduced latency.

If the 5G speed predictions were confirmed, it would only take a few seconds to download a 4K movie from a streaming video platform. A dream for users all over the world.

In my opinion, a gold mine for operators who broadcast multimedia content such as the current Netflix could be.

Intel and the milestone of 2020

It is surprising to think of the speed with which we are rapidly approaching the initial goal of the 5G New Radio (NO), the wireless radio standard that will form the foundation of 5G, just like LTE was for 4G.

The days when it was necessary to wait for a silicon chip from 12 a 18 months to test the latest set of specs have now passed. Today's researchers and engineers work in rapid prototyping mode.

Intel's 5G mobile test platform will begin supporting the new non-standalone NR standard in the fourth quarter of this year, for tests and live tests. It is a world first.
In any case, remember that 5G is much more than wireless. To become reality, A network transformation is required to replace static and stationary equipment with a virtualized and software-defined network. Fortunately, this change is already happening.
5G can only become reality when the network, the cloud and devices will be able to communicate thanks to a powerful end-to-end 5G solution.

In fact, the implementation of 5G is not a sprint, but a marathon. We can assume that in a few years, when our cars drive themselves and our smart homes make our lives easier, we will look back with a sense of nostalgia for our smartphones and apps that were changing the world at the time. But without a doubt we will be reaching a new technological innovation

Ericsson gives the bridge solution

Ready to launch the new radio system that accompanies the transition from 4G. By amplifying the spectral capacity of the current 4G.

Fredrik Jejdling (Head of Business Area Networks di Ericsson) he claims: “We allow operators to be ready to jump to the standard of the future using the same hardware components”

Ready to launch the new radio system that accompanies the transition from 4G to 5G

Ericsson lancia (in the second half of the 2018) Air 3246, a "facilitator" of both 4G and 5G. The product will allow TLCs - especially in metropolitan areas - to bring 5G to their subscribers using today's mid-band spectrum and to increase the capacity of LTE networks.

“Now let's expand the 5G platform , the new Radio solution will allow operators to improve 4G capacity for their subscribers and be ready for tomorrow's 5G, using the same hardware components. We also integrate the products with a series of network services, thus simplifying the path of our customers towards 5G. " Always Fredrik Jejdling says: “Milestone on the way to the new standard. We work to improve the end user experience and develop new features thanks to greater spectral efficiency on the LTE”

Performing a douwnload from a mobile network at a speed higher than gigabit per second is a reality. Achieve a download speed of 1.07Gbps with a very simple idea, parallel multiple transmitters,

The 1.07Gbps milestone was achieved using 12 simultaneous Lte streams, This is a fundamental step in the path towards 5G that will allow better average speed for all users

SoftBank and Huawei experiment

SoftBank and Huawei have joined forces to perform four tests with the aim of showing the potential of 5G in different areas.

Small additional news these days, Huawei has outperformed Apple in the production of smartphones, ranking second after the unreachable (at the moment) Samsung.

The first test involved an Ultra HD video transmission in real time. A 4K resolution video camera was installed inside a laboratory to shoot scenes outside. The data collected by the video camera were compressed in real time using an encoder and transmitted through the 5G network to a UHD monitor via a decoder where the original data was recovered.

In this experiment, the landscape of the Odaiba Tokyo Bay area was correctly displayed on the UHD monitor using the ultra-high performance provided by the 5G network. This technology can be applied to various sectors, including tele-medicine or tele-teaching.

A camera was used for the second test 180 degrees equipped with four lenses, each pointed in different directions; the filmed scene was sent to smartphones and tablets through a 5G network.

Four different cameras have been installed to capture the landscape from different angles; the images acquired by the cameras were assembled to make a panoramic video a 180 degrees that allowed multiple simultaneous views. Combined with a 5G network, this technology can be applied to virtual reality (VR) or augmented reality (WITH).

For the third experiment, a robotic arm was used for the game of table hockey. A camera installed on the top of the hockey table has detected the position of the puck to calculate its trajectories. The result was then sent to the robotic arm control server to record its movements. The robotic arm managed to revive the disc hit by a player and addressed in various trajectories. This technology can be applied, for example, to industrial automation.

The fourth and final test instead involved remote rendering with GPU servers. Rendering is a technology used to make videos or images using GPU computers (graphics processing unit). This technology is used for processing HD video for video games or for CAD (Computer Aided Design) and consumes a great deal of computing resources.

A GPU server located near a 5G base station has rendered and the image generated by the GPU server has been sent to the tablet at very high speed, with extremely low latency. This technology can be applied to check CAD data on a construction site with a tablet or enjoy an HD gaming application on smartphones.
