Consumer demands determine the evolution of mobile broadband services. Innovative solutions will be needed to cope with the expected increase in traffic, which is estimated to be 10 to 100 times greater between 2020 and 2030, and the growing number of devices and services, as well as at the request of improved affordability and user experience. The number of devices connected to the Internet is expected to reach 50 billion by 2025.

Fifth generation (5G) mobile technologies are expected to connect people, objects, data, applications, transportation systems and cities in smart network communication environments. They should make it possible to transport a considerable volume of data more quickly, to reliably connect a very large number of devices and to process very large volumes of data in record time.

5G technologies are expected to support applications such as smart homes and buildings, smart cities, 3D video, cloud work and games, remote medical services, virtual reality and augmented reality, as well as massive machine-to-machine communications for industrial automation systems. 3G and 4G networks are currently struggling to support these services.

While the business case for using 5G technologies, as well as their scope, raises some issues, these innovative features and services require finding new ways of deploying advanced mobile services, as well as finding new ways to deploy advanced mobile services. New approaches allowing 5G technologies to work together in industrial environments, as part of machine-to-machine communications, the Internet of Things (IoT) or connected vehicles.

IMT-2020 - the expression used in ITU for 5G standards - is expected to continue to be deployed from 2020, with 5G trials and pre-commercial activities already completed to help countries assess the technologies and frequency bands that can be used for these purposes. The first large-scale commercial deployments for 5G are planned to be launched after specifications for IMT-2020 have been completed.

ITU plays a leading role in the management of the radio frequency spectrum and the development of globally applicable standards for IMT-2020. The objective of its work is to have stable regulations at the international level, sufficient spectrum and suitable standards for IMT-2020 as well as a core network allowing the successful deployment of 5G at regional levels. And international. At the 2019 ITU World Radio communication Conference (WRC-19), stakeholders around the world reached consensus to identify additional frequency bands for IMT-2020.

5G will accelerate the achievement of the 17 Sustainable Development Goals (SDGs), be it the goal of affordable clean energy or the goal of eradicating hunger.

CHALLENGES AND SOLUTIONS: BUILDING THE 5G NETWORKS OF TOMORROW

 

When deployed, 5G networks are expected to provide increased throughput and capacity to support massive machine-to-machine communications and to provide highly reliable low latency (delay) service in support of applications to critical time. Based on the tests carried out to date, 5G networks are starting to prove their worth by providing high performance in different scenarios, for example in densely populated urban areas or for access points inside buildings. .

Given these ambitious goals, 5G networks are associated with significant challenges. For 5G to deliver on its promises of supporting increased traffic and higher throughput, much more spectrally efficient technologies will be required, as well as much higher frequencies. Number than what 3G and 4G systems are currently using.

 

Among these additional frequencies, some will be located in bands above 24 GHz, which poses considerable problems. The first of these problems relates to the propagation characteristics of millimeter waves. These radio waves propagate over distances much shorter than those in the bands between 1 and 6 GHz and those located below 1 GHz.

To cover a given area, it will therefore require many more base stations, which will make the infrastructure more complex, especially given the need to install radio equipment on public infrastructure, such as traffic lights, street lights, utility poles and power supplies.

 

5G feeder links between base stations and the core network (backhaul), which rely on both fiber optic and wireless technologies, are also a challenge. It is necessary to carry out large-scale works in order to implement optical fiber services and to guarantee the availability of wireless connection solutions with sufficient capacities, such as microwave links and satellite links, or even station stations. On high altitude platforms (HAPS) where they are deployed.

In addition, the radio frequency spectrum is a scarce and very valuable resource, and there is strong competition - which, moreover, tends to intensify - in this regard at national, regional and international levels. Since the radio spectrum is divided into frequency bands which are allocated to different radio communication services, each band should only be used by services capable of coexisting with each other without causing harmful interference to services using adjacent bands. .

 

Studies carried out by ITU-R focus on the sharing and compatibility of mobile services with other existing radio communication services, including satellite communications, weather forecasting, monitoring of terrestrial resources and climate change, and monitoring. Radio astronomy.

National and international regulations must be adopted and enforced across the world, in order to avoid interference between these services and 5G networks and to establish a viable mobile ecosystem for the future, while reducing prices through economies of scale in the global market and by promoting interoperability and roaming.

 

For these reasons, it was important to identify the additional frequency bands that will be used by 5G and to harmonize them globally and regionally. For the same reasons, radio technologies used in 5G devices must be based on globally harmonized standards.

ITU CONTRIBUTION

 

ITU plays a leading role in the management of the radio frequency spectrum and the development of globally applicable standards for IMT-2020. Its activities promote the development and implementation of international regulations and standards to ensure that 5G networks are secure and interoperable, and that they operate without causing or suffering harmful interference to services. Using adjacent bands.

 

Drawing on its experience in developing standards for international mobile telecommunications (IMT) in the context of 2G, 3G and 4G, ITU brings together eminent engineers and specialists in the field of connection technologies. Fixed and mobile, in order to carry out work on 5G and on future generations of mobile broadband services.

 

As part of the ITU program for IMT-2020, members of the Union are developing international standards to ensure the proper functioning of 5G networks.

Delegates at the 2019 World Radio communication Conference (WRC-19) identified additional frequency bands for IMT to facilitate the development of fifth generation (5G) mobile networks.

 

While identifying the frequency bands 24.25-27.5 GHz; 37-43.5 GHz; 45.5-47 GHz; 47.2 GHz-48.2 GHz and 66-71 GHz for the deployment of 5G networks, WRC-19 also took measures to ensure adequate protection of the Earth exploration-satellite services, including the service meteorological and other passive services in adjacent bands.

 

Several countries have started testing for 5G, and the results are being evaluated. Strategies for the deployment of 5G have been put in place in many parts of the world. A few regulators have already auctioned licenses for the operation of 5G networks in the frequency bands allocated to the land mobile service in the Radio Regulations (RR). The first large-scale commercial deployments for 5G are planned to be launched after specifications for IMT-2020 have been completed.
