[0:06]Greetings from the Radiocommunication Bureau.
[0:23]ITU-R defines and manages the international regulatory framework for the use of spectrum and satellite orbits by radiocommunication services. ITU-R also develops worldwide standards on radiocommunications. More than 1,500 standards are currently in force and available online for free.
[0:52]The Radio Regulations (RR), the international treaty governing the use of spectrum, are revised and updated during the ITU World Radiocommunication Conferences (WRCs) every 3-4 years.
[1:12]The Master International Frequency Register (MIFR) records the use of spectrum by radiocommunication stations worldwide to provide international recognition and protection against harmful interference. MIFR contains more than 3.14 million records for terrestrial stations and over 2,200 satellite networks.
[1:42]ITU-R applies the provisions of the Radio Regulations for the coordination and recording of satellite frequency assignments and orbits in the Master International Frequency Register (MIFR) and for protecting these assignments from harmful interference.
[2:07]The Radiocommunication Bureau (BR) assists Membership in resolving cases of harmful interference and develops best practices on spectrum management. Over 1140 reports on harmful interferences and infringements were processed in 2019.
[2:32]The Maritime mobile Access and Retrieval System (MARS) provides access to operational information concerning ship, coast stations, search and rescue aircraft, AIS aids to navigation (AtoNs), accounting authorities, etc. The MARS database contains more than 860,000 ship stations and 2,300 coast stations around the world.
[2:57]Radio frequencies for aeronautical communications and navigation are considered as safety of life requiring special protection. The ITU Radio Regulations reserve specific frequency bands exclusively for communications related to safety of flight worldwide (both route and off-route services).
[3:24]All 3G and 4G mobile systems are based on ITU's International Mobile Telecommunications - IMT- globally harmonized standards for mobile broadband. ITU-R studies on IMT for 2020 and beyond (5G) are ongoing for IMT-2020 mobile systems with key design principles of flexibility and diversity to serve many different use cases and scenarios. WRC-19 identified 17.25 GHz of harmonized spectrum between 24.25 GHz and 71 GHz to enable IMT-2020/5G developments. The Conference also opened the band 5150 - 5250 MHz for using RLAN/Wi-Fi in automobiles and trains and for a limited outdoor usage. ITU-R develops the standards for digital terrestrial sound and television broadcasting systems, such as 3DTV (Three Dimensional Television), HDTV and UHDTV (Ultra High Definition Television), Integrated Broadcast-Broadband (IBB) systems, High Dynamic Range (HDR), Advanced Immersive Audio-Visual (AIAV) systems, which include Virtual Reality and Augmented Reality (AR/VR) and Advanced Audio Systems. ITU-R is working on technologies to improve accessibility to broadcasting services, including Signing, Real-time closed-captioning using speech recognition, Multimedia Speech rate conversion technology, browsing system for the visually impaired, Machine translation to sign language with CG-animation, Device for evaluating broadcast background sound balance, etc. Around 485,000 broadcasting Television and Sound frequencies are managed by ITU.
[4:42]Advances in satellite design, manufacturing and launch service capabilities have enabled the deployment of non-GSO FSS constellations. WRC-19 established a new sharing environment for non-GSO satellite systems in the 50/40 GHz frequency range and agreed on a milestone-based deployment process ensuring the timely development of mega-constellations.
[5:08]Recent ITU-R achievements include worldwide allocations of spectrum for operation of 24-hour thunderstorm/lightning detection systems and oceanographic radars.
[5:31]ESIM are intended to provide broadband communications, including Internet connectivity to aircraft, ships and land vehicles. WRC-19 identified 2 x 2 GHz of additional spectrum for use by ESIM communicating with GSO FSS space stations and decided to study in time for WRC-23 the use of the 30/20 GHz frequency range for ESIM communicating with non-GSO FSS systems. HAPS are fixed aerial platforms at altitudes of 20-50 km providing communication services to the population and backhaul for cellular networks, especially in remote and rural areas. WRC-19 identified five globally or regionally harmonized frequency bands for HAPS in the millimeter range to deliver affordable broadband connectivity in underserved communities and in rural and remote areas.
[6:16]ITU-R develops standards on the use of fixed and mobile satellite systems for warning, disaster response and relief operations. ITU-R also assists emergency communication activities for Members by maintaining a database of available frequencies/bands for use in emergency situations. Nearly every ITU-R Study Group has a role to play in Disaster Relief.
[6:42]ITU-R has provided required spectrum for high resolution 79 GHz automotive radars to improve road safety and security. WRC-19 continued harmonization of frequency bands: - for evolving ITS, to assist safe driving and transportation system efficiency; - for Railway Radiocommunication Systems between Train and Trackside (RSTT), vital for safe train operation, traffic control and passenger safety.
[7:08]AI will make radiocommunications smarter. In return, radiocommunications will enable AI functioning and connectivity. ITU-R is studying potential application of AI in different radio systems, such as broadcasting services, cognitive radio systems (CRS), IMT-2020 (5G), Intelligent Transport Systems (ITS), Internet of Things (IoT), satellite systems, as well as in spectrum management including monitoring systems, and some others.
[7:35]ITU's global membership includes: 193 Member States some 900 companies, universities, and international and regional organizations.
