ITU identifies additional frequency bands to enable 5G deployment
UNITED Nations (UN) arm in-charge of global communications, the International Telecommunications Union (ITU), has identified new frequency band for the deployment of fifth-generation (5G) network come 2020.
Arising from the World Radiocommunication Conference 2019 (WRC-19), in Egypt, the delegates, submitted that the frequencies would help strengthen global communication system.
5G is expected to connect people, things, data, applications, transport systems and cities in smart, networked communication environments. It will transport a huge amount of data much faster, reliably connect an extremely large number of devices and process very high volumes of data with minimal delay.
5G technologies are expected to 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. 3G and 4G networks currently face challenges in supporting these services.
These new functionalities and new services, according to ITU necessitated a new way of deploying advanced mobile services, as well as new approaches in making 5G technologies work together in industrial settings by machine-to-machine communications, Internet of Things (IOT) or with connected vehicles.
ITU said it is on the front line of developing standards to allow all of these functionalities to work together.
New Resolutions approved at WRC-19 pointed out that ultra-low latency and very high bit-rate applications of IMT will require larger contiguous blocks of spectrum than those available in frequency bands that had previously been identified for use by administrations wishing to implement IMT. They also pointed that harmonized worldwide bands for IMT are desirable in order to facilitate global roaming and the benefits of economies of scale.
While identifying the frequency bands 24.25-27.5 GHZ, 37-43.5 GHZ, 45.5-47 GHZ, 47.248.2 and 66-71 GHZ for the deployment of 5G networks, WRC-19 also took measures to ensure an appropriate protection of the Earth Exploration Satellite Services, including meteorological and other passive services in adjacent bands.
In total, 17.25 GHZ of spectrum has been identified for IMT by the Conference, in comparison with 1.9 GHZ of bandwidth available before WRC-19. Out of this number, 14.75 GHZ of spectrum has been harmonized worldwide, reaching 85 per cent of global harmonization.
In addition, WRC-19 has also defined a plan of studies to identify frequencies for new components of 5G. As an example, to facilitate mobile connectivity by High Altitude IMT Base Stations (HIBS).
