Consumer demands are shaping the evolution of mobile broadband services. Innovative solutions are needed to address the expected traffic growth between 2020 and 2030, the growing number of devices and services, and the demands for improved economics and economics. User experience. In a smart network connectivity world, the fifth-generation (5G) mobile technology is supposed to link users, items, data, apps, transportation networks, and cities. This should ensure that a significant amount of data can be transferred faster, a very large number of devices can be reliably connected, and a very large amount of data can be processed within the recording time.
Challenges and Solutions: Building the 5G Network of the Future
When deployed, 5G networks are expected to increase throughput and capabilities to support large-scale machine-to-machine communication and provide very reliable low-latency (latency) services to support critical time applications. Based on tests conducted so far, 5G networks have begun to prove themselves by providing high quality operations in a variety of scenarios, such as in densely populated urban areas or access points inside buildings.
Given these ambitious goals, 5G networks are associated with significant challenges. For 5G to deliver on its promise to support increased traffic and higher throughput, it requires far more frequencies and far more spectrum-efficient technologies than the 3G and 4G systems currently in use.
Some of these additional frequencies are in the 24 GHz and above band, which creates significant problems. The first problem is the propagation characteristics of millimeter waves. These radio waves propagate over a much shorter distance than radio waves in the 1 to 6 GHz band and sub-1 GHz bands.
It is necessary to adopt and enforce national and international regulations globally to avoid interference between these services and 5G networks and to build a viable mobile ecosystem for the future while lowering prices and facilitating interoperability through economies of scale in global markets. . roaming.
For this reason, it was important to identify additional frequency bands to be used by 5G and harmonize them globally and regionally. For the same reason, the wireless technology used in 5G devices must be based on globally harmonized standards.
The ITU plays a leading role in the management of the radio frequency spectrum and in 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, interoperable, and operate without causing or adversely affecting services that use adjacent bands.
As part of the ITU IMT-2020 program, allied member states are developing international standards to ensure the smooth functioning of 5G networks.
Delegates from the 2019 World Radiocommunication Conference (WRC-19) have identified additional frequency bands for IMTS to facilitate the development of fifth-generation (5G) mobile networks.
Several countries have launched 5G testing and the results are being evaluated. 5G deployment strategies are being implemented in many places around the world. Some regulators have already auctioned off-licenses to operate 5G networks in the frequency bands allocated for land mobile services in the Radio Regulation (RR). After the IMT-2020 specification is completed, it is planning to launch the first large-scale commercialization for 5G.
