Delegates at the World Radiocommunication Conference 2019 (WRC-19) have identified additional radio-frequency bands for International Mobile Telecommunications (IMT), which will facilitate the development of fifth-generation (5G) mobile networks.
Additional bands identified to enable 5G deployment
While identifying the frequency bands 24.25-27.5 GHz, 37-43.5 GHz, 45.5-47 GHz, 47.2-48.2 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% 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). HIBS may be used as a part of terrestrial IMT networks to provide mobile connectivity in underserved areas where it is difficult to be covered by ground-based IMT base stations at a reasonable cost.
IMT-2020, the name used in ITU for the standards of 5G, is expected to continue to be developed from 2020 onwards, with 5G trials and commercial activities already underway to assist in evaluating the candidate technologies and frequency bands that may be used for this purpose.
The first full-scale commercial deployments for 5G are expected sometime after IMT-2020 specifications are in force.
