3. Intoduction to ITU Introduction Every sector of modern life whether it is business, culture, or entertainment, at work and at home – depends on information and communication technologies. Today, there are billions of mobile phone subscribers, nearly five billion people with access to television, and tens of millions of new Internet users every year. The satellite service is used by hundreds of millions of people around the world for getting directions from a satellite through the navigation system, watching television from isolated areas, in checking the weather forecast or every day for compressing videos on mobile phones, music players and cameras. The oldest agency of the United Nations - The International Telecommunication Union (ITU) was established on 17May 1865 as the International Telegraph Union headquartered, in Geneva, Switzerland. This organization is responsible for many matters related to information and communication technologies. The ITU's global membership includes 193 countries and around 900 business, international and regional organizations, and academic institutions. The ITU was initially known as the International Telegraph Union which aimed at connecting telegraphic networks between countries. With the advent of new communications technologies, its mandate consistently broadened. To reflect its expanded responsibilities over radio and the telephone, it adopted its current name International Telecommunication Union in 1934. The ITU entered into an agreement on15 November 1947 with United Nations which was newly created to become a specialized agency within the UN system, which formally came into force on 1 January 1949. Through ITU governments and the private sector coordinate global telecommunications networks and services.

4. What is the role of ITU? The role of the International Telecommunication Union (ITU) are Coordinating/International cooperation.The majority of Internet connections are carried through ITU standards. The management of spectrum and orbit, GPS navigation and online maps, which enable communications even in the remotest parts of the planet, maritime and aeronautical communications, televisions and mobile phones connectivity, weather information etc... all these are coordinated by ITU. ITU standards, protocols and international agreements are the essential elements for the global telecommunications to make phone calls possible to someone in any country. To support the future upcoming networks and services, ITU works with the industry.People around the globe get empowered through technical education and training. The ITU is the body through which governments and the private sector coordinate global telecommunications networks and services. TV broadcasting, amateur radio, and next-generation networks, follow the technical standards and policy framework to avoid forging.

5. What are the 3 ITU sectors? The ITU is organized into three sectors, which were created during the restructuring of ITU in1992. Each sector managing a different aspect of the matters handled by the Union, as well as ITU Telecom. 1)Radiocommunication , known as ITU-R 2)Telecommunication Standardisation known as ITU-T, and 3)Telecommunication Development known as ITU-D. 1) Radio communication (ITU-R) - Established in 1927 as the International Radio Consultative Committee or CCIR, coordinates this vast and growing range of radiocommunication services and international management of the radio-frequency spectrum and satellite orbit resources. In1992, the CCIR became the ITU-R. 2) Telecommunication Standardization (ITU-T) - ITU -T established in 1956, as the International Telephone and Telegraph Consultative Committee or CCITT. Since the inception of ITU, global telecommunication standardization was its original purpose except for radio. The CCITT became the ITU-T in 1993. The Standardization work is undertaken by Study Groups, such as Study Group 13 on Networks and Study Group 16 on Multimedia, and Study Group 17 on Security. World Telecommunication Standardization Assembly is the parent body of the Study Groups. New work areas In Focus Groups new work areas can be developed like the ITU-WHO Focus Group on Artifical Intelligence for Health and Focus Group on Machine Learning for 5G. Major events for the world's ICT community are also organized by the ITU Telecom 3) Telecommunication Development ( ITU-D) - Established in 1992, this Sector provides the Secretariat for the Broadband Comission for Sustainable Development. It helps in spreading equitable, sustainable, and affordable access to information and communication technologies (ICT).
