The ITU-R Recommendations constitute a set of international technical standards developed by the Radiocommunication Sector (formerly CCIR) of the ITU. They are the result of studies undertaken by Radiocommunication Study Groups on:
| 5.1 | the use of a vast range of wireless services, including popular new mobile communication technologies; |
| 5.2 | the management of the radio-frequency spectrum and satellite orbits; |
| 5.3 | the efficient use of the radio-frequency spectrum by all radiocommunication services; |
| 5.4 | terrestrial and satellite radiocommunication broadcasting; |
| 5.5 | radio wave propagation; |
| 5.6 | systems and networks for the fixed-satellite service, for the fixed service and the mobile service; |
| 5.7 | space operation, Earth exploration-satellite, meteorological-satellite and radio astronomy services. |
| 5.8 | The ITU published Recommendations, Resolutions and Reports with respect to the utilisation of band 470 – 690 for purposes of advising Administrations the planning criteria, including protection ratios, for various methods of providing second generation digital terrestrial television broadcasting (DTTB) systems in the VHF/UHF bands as follows: |
| 5.8.1 | Recommendation ITU-R P.1546-6 (08/2019): Method for point-to-area predictions for terrestrial services in the frequency range 30 MHz to 4 000 MHz |
| 5.8.2 | Recommendation ITU-R M.2012-4 (11/2019): Detailed specifications of the terrestrial radio interfaces of International Mobile Telecommunications-Advanced (IMT Advanced); |
| 5.8.3 | Report ITU-R2241-0 (2011) Compatibility studies in relation to Resolution 224 in the bands 698-806 MHz and 790-862 MHz; |
| 5.8.4 | Report ITU-R BT.2386-2 (04/2019) Digital terrestrial broadcasting: Design and implementation of single frequency networks (SFN) |
| 5.8.5 | Report ITU-R M.2074-0 (2006): Report on Radio Aspects for the terrestrial component of IMT-2000 and systems beyond IMT-2000; |
| 5.8.6 | Recommendation ITU-R M.1645-0 (06/2003) Framework and overall objectives of the future development of IMT-2000 and systems beyond IMT-2000; |
| 5.8.7 | The ITU Radio Regulations (RR) Edition 2016, Provision Number 5.1.2 of the Geneva 2006 (GE06) Agreement, and the WRC rev 2019 Resolution 224-4 (Rev. WRC 15), Resolution 260 (WRC-15) and the results of activities undertaken by the within ITU Region 1 (African Region); |
| 5.8.8 | Recommendation ITU-R M.2090-0 (10/2015) on specific unwanted emission limit of International Mobile Telecommunication (IMT) mobile stations operating in the frequency band 694-790 MHz to facilitate the protection of existing services in the ITU Region 1 in the frequency band 470-694 MHz; |
| 5.8.9 | Recommendation ITU R M.1036-6 (10/2019) dealing with the lower duplexer of the Frequency arrangement A5 in Recommendation ITU R M.1036-6 (i.e. uplink in 703-733 MHz) and a maximum output power of 23 dBm, to provide for a nine (9) MHz guard band between Broadcasting and IMT; and |
| 5.8.10 | ITU Report ITU-R BT.2339-0, (11/2014) with respect to co-channel sharing and compatibility studies between digital terrestrial television broadcasting and IMT in the frequency band 694-790 MHz in the GE06 planning area were studied and ITU-R Reports was developed in this respect. |
