5G: Fifth Generation of Mobile Technologies

5G, the fifth generation of mobile technologies, promises to be a huge step forward in speed, reliability, and connectivity. 5G, operating on higher frequency bands, is likely to transfer data at unparalleled speeds, which can reach 20 gigabits per second. This revolutionary technology not only enables faster downloads and borderless streaming, but it also promotes the Internet of Things (IoT) ecosystem. With low latency and increased capacity, 5G supports promising commercial applications, such as augmented reality, virtual reality, and autonomous vehicles. The deployment of large MIMO (Multiple Input, Multiple Output) antennas and advanced beamforming technologies optimizes network efficiency, ensuring a more stable and responsive communications network. As 5G networks continue to grow globally, they have the potential to revolutionize industries, spur innovation, and redefine the way we experience connectivity.

Overview

Mobile broadband services are evolving based on consumer demands, with traffic expected to increase by 10-100 times from 2020 to 2030. The proliferation of devices, popularity and demand for improved user experience, as well as the need for convenient user experience are driving the demand for new solutions. The number of devices connected to the Internet is expected to grow to 50 billion any time after 2025.

The fifth generation of mobile technologies, i.e. 5G, connects people, objects, data, applications, transportation systems and cities into smart networked communication environments. These networks transport much more data faster, securely connect an extremely large number of devices, and process enormous amounts of data with minimal delay.

5G technologies support applications such as smart homes and buildings, smart cities, 3D video, work and play in the cloud, remote medical services, virtual and augmented reality, and massive machine-to-machine communications for industry automation. The legacy 3G and 4G networks are facing challenges in supporting these services.

Despite challenges in the business case and use case, these new capabilities and new services represent a new way of adopting advanced mobile services and industrializing 5G technologies with machine-to-machine communications, the Internet of Things (IoT) or connected vehicles. Takes into account the need for a new approach to operations.

ITU is a leading global partner in managing the radio spectrum and developing globally applicable standards for IMT-2020.

Mika is playing. ITU has worked towards providing stable international regulations, adequate spectrum, and appropriate standards for IMT-2020 and core networks to enable successful 5G deployment at regional and international levels. At the ITU World Radiocommunication Conference 2019 (WRC-19), global stakeholders reached consensus and identified additional spectrum for IMT-2020.

The first version of the IMT-2020 specifications, the name used by the ITU for the standards for 5G, was published in February 2021 (ITU-R M.2150). Since then, over 200 commercial launches and over 1200 announced devices (with at least 870 commercially available) have been seen worldwide.

Initially, three technologies were scheduled to receive recognition as meeting IMT-2020 specifications: 3GPP 5G-SRIT, 3GPP 5G-RIT, and 5Gi. Three, provided by the Third Generation Partnership Project (3GPP), noted the establishment of “standalone (SA)”, 3GPP 5G-RIT, and the establishment of “non-standalone (NSA)”, 3GPP 5G-SRIT, 5G. The deployment model, in which 5G-SA features a completely new RAN- and core-architecture, without the need for any 4G-network.
5Gi, provided by the Telecommunication Standards Development Society India (TSDSI), is an upgraded version of 3GPP 5G-RIT, primarily designed to improve rural coverage.

In February 2022, a fourth technology was recognized as DECT 5G-SRIT that meets the standard. Due to cellular and autonomous, open-ended technology, it supports a range of use cases from wireless telephony and audio streaming to industry Internet of Things (IoT) applications in smart cities.

ITU has preparatory activities for the development of IMT for 2030 and beyond have begun, setting the stage for new research activities. ITU-R Working Party 5D, which is tasked with studying IMT systems, has begun to study future requirements for the next generation of global international mobile telecommunications. The upcoming World Radiocommunication Conference (WRC-23), which the UAE will host, will consider further aspects of the IMT system, among other topics.

5G and the next generation of mobile networks are intended to accelerate the achievement of all 17 Sustainable Development Goals (SDGs), from finance and clean energy to zero hunger.

Challenges and Solutions: Building 5G Networks For The Future

Building 5G networks for the future has been a transformative journey with significant features and many challenges. The launch of 5G networks comes with greater speed, capacity, and capabilities, especially in supporting massive machine-to-machine communications and providing low-latency, high-fidelity services for time-critical applications. However, we have faced many difficulties in achieving these characteristics.

One of the main challenges in deploying 5G networks is the need for more spectrum and spectrally efficient technologies. The speed and data rates advances achieved by 5G need to be tested in frequency bands above 24 GHz, with spectrum used between meterband (between 1-6 GHz) and lowband (below 1 GHz). Much more will be required from lower frequency systems. A public domain would be required to determine where these radio waves would propagate, increasing the complexity of the structures that would be used, such as traffic lights, lampposts, utility poles, and power transmission lines. .

Additionally, fallback, which occurs over connection links (backhaul) between 5G base stations and the core network, presents another challenge. There is a reliance on both wired and wireless technologies, with much work to be done to implement wired services and ensure the availability of wireless backhaul solutions. This includes investigating options such as microwave and satellite links, and perhaps high-altitude platform stations (HAPS) systems.

And besides, the spectrum is a fragile and very valuable resource, and there is intense – and growing – competition for spectrum at national, regional, and international levels. Since the radio spectrum is divided into frequency bands dedicated to different radiocommunication services, each band must be used only by designated services that have established technical conditions so that they can simultaneously support each other without causing harmful interference. .

ITU-R studies have examined the interoperability and compatibility of mobile services with many other existing radiocommunication services, particularly for services related to satellite communications, weather forecasting, Earth resource and climate change monitoring, and radio astronomy.

It is necessary to integrate national and international methods and make it reliable through global market economic parameters to create a robust mobile ecosystem to handle price reduction, interconnection and roaming.

It was therefore important that the spectrum used by 5G be identified and coordinated at the global and regional levels. For similar reasons, the radio technologies used in 5G devices must be supported by globally coordinated standards. National and international methods for handling interoperability between these applications should be modestly adopted and implemented to ensure that 5G and these services do not create barriers and remain a promising mobile ecosystem for the future – lack of values To improve capacities in related disciplines through and through sharing at the international level and inter-union.
