The ninth session of the International Telecommunication Union Administrative Council was held in Geneva from May 1 to 20, 1954, under the chairmanship of Charles J. Acton (Canada). It was reported that the Council had kept the ITU budget within the limits set at the Buenos Aires Conference, although it had not been easy to strike a balance between the desire of the staff to improve its lot and the desire of ITU members to cut their financial burden as far as possible. In the interests of economy, the Council decided to postpone consideration of the proposed convening of the Telegraph and Telephone Conference until the Council's tenth session; it would, therefore, be impossible for the Conference to meet before 1956. The Council also reported that it was impossible to foresee when the Radio Conference could be convened; the question was to be reviewed by the Council in 1955. The question of postponing the next Plenipotentiary Conference of ITU, which would normally meet in 1957, for one or two years was discussed during the Council's ninth session; further discussion was scheduled for the tenth session.

The seventh plenary assembly of the International Telegraph Consultative Committee (CCIT) of the International Telecommunication Union met in Arnhem, Netherlands, from June 5 through 13, 1953, under the chairmanship of Mr. van der Toorn (Netherlands). Most of the work of the session was carried on in study groups on the following subjects: 1) general telegraphy, 2) technical aspects of the establishment, operation and maintenance of telegraph channels, 3) technical aspects of telegraph apparatus, 4) vocabulary, symbols and classification, 5) phototelegraphy and facsimile, 6) technical aspects of switching in the service of start-stop apparatus, 7) European telegraph network operated by start-stop apparatus, 8) operational methods and quality of service, 9) services offered to users and rates other than telex rates, and 10) international service of telegraph subscribers and rates for such service. At the request of the Buenos Aires Plenipotentiary Conference of ITU, CCIT considered the possibility of amalgamating itself with the International Telephone Consultative Committee (CCIF) and concluded, by a vote of 16 to 11 with 1 abstention, that such a course would not serve the best interests of ITU. CCIT decided to hold its eighth plenary assembly in Geneva in the first half of 1956.

The seventeenth Plenary Assembly of the International Telephone Consultative Committee (CCIF) was held in Geneva from October 4 to 12, 1954, under the chairmanship of Mr. Wettstein (Switzerland). Delegates from 36 countries attended the Assembly, which in pursuance of a resolution of the Plenipotentiary Conference of the International Telecommunication Union (ITU) held at Buenos Aires in 1952, considered the possible amalgamation of the CCIF and the International Telegraph Consultative Committee (CCIT). After considerable debate, the Assembly by a vote of 21 to 13 with 1 abstention expressed the view that such an amalgamation would be in the interests of the ITU. Among the technical matters dealt with at the seventeenth Plenary Assembly were 1) the general switching program, 2) protection of telecommunication lines from danger and disturbances due to neighboring power lines, 3) protection of telecommunication cables from corrosion, 4) transmission, including telephone transmission in the international service, general characteristics of telephone circuits, the use of telephone circuits for telegraphy or phototelegraphy, broadcast and television relays over metallic lines, specification of carrier systems on metallic lines, radio relay links, links between mobile radiotelephone stations and international telephone lines, the maintenance and regulation of circuits and transmission systems, international operation and rates, and international signalling and switching; and 5) graphic and letter symbols, telephone vocabulary.

At the conclusion of the two International Telecommunication Union (ITU) conferences held in Geneva in 1959—the Plenipotentiary (October 14 to December 16) and the Administrative Radio (August 17 to December 17)—two international documents were officially signed by the representatives of 85 and 84 countries respectively, namely: 1) the new Convention, replacing the International Telecommunication Convention of Buenos Aires, 1952; and 2) the new Radio Regulations, replacing those of Atlantic City, 1947. The Convention was to take effect on January 1, 1961, and the Radio Regulations on May i, 1961. Some additional protocols had to be signed as well, so that certain decisions (for example, the elections of the newly-constituted Administrative Council, the Secretary-General, and the Deputy Secretary-General, and changes made in the budget system) could take effect forthwith. Numerous recommendations and resolutions were also adopted, and decisions concerning the way ITU was organized, how it was run, and its future development were reached by the Plenipotentiary Conference, the chairman of which was Mr. J. D. H. van der Toorn, head of the Netherlands delegation. The chairman of the Radio Conference was Mr. Charles J. Acton, head of the Canadian delegation.

The quinquennial Plenipotentiary Conference of the International Telecommunication Union opened in Buenos Aires on October 3, 1952; the final act of the Conference was signed on December 22, 1952. The agreement reached at the Extraordinary Administrative Radio Conference of 1951 was endorsed by the Conference. After rejecting a proposal to eliminate the International Frequency Registration Board, the Conference considered various less drastic proposals to alter the structure and organization of the Board, and finally decided to maintain the Board at its present membership. As no new elections to the Board were held at the Buenos Aires meeting, the current members of the Board were considered reappointed. In revising the Atlantic City Convention, the Conference decided that countries, rather than individuals, should be elected to the Board and that each elected country should nominate one of its nationals to serve on the Board.

During the last decade, Machine Learning (ML) has increasingly become a hot topic in the field of Computer Networks and is expected to be gradually adopted for a plethora of control, monitoring and management tasks in real-world deployments. This poses the need to count on new generations of students, researchers and practitioners with a solid background in ML applied to networks. During 2020, the International Telecommunication Union (ITU) has organized the "ITU AI/ML in 5G challenge", an open global competition that has introduced to a broad audience some of the current main challenges in ML for networks. This large-scale initiative has gathered 23 different challenges proposed by network operators, equipment manufacturers and academia, and has attracted a total of 1300+ participants from 60+ countries. This paper narrates our experience organizing one of the proposed challenges: the "Graph Neural Networking Challenge 2020". We describe the problem presented to participants, the tools and resources provided, some organization aspects and participation statistics, an outline of the top-3 awarded solutions, and a summary with some lessons learned during all this journey. As a result, this challenge leaves a curated set of educational resources openly available to anyone interested in the topic.

AbstractThis paper documents a simple parametric polynomial line-of-sight channel model for 100–450 GHz band. The band comprises two popular beyond fifth generation (B5G) frequency bands, namely, the D band (110–170 GHz) and the low-THz band (around 275–325 GHz). The main focus herein is to derive a simple, compact, and accurate molecular absorption loss model for the 100–450 GHz band. The derived model relies on simple absorption line shape functions that are fitted to the actual response given by complex but exact database approach. The model is also reducible for particular sub-bands within the full range of 100–450 GHz, further simplifying the absorption loss estimate. The proposed model is shown to be very accurate by benchmarking it against the exact response and the similar models given by International Telecommunication Union Radio Communication Sector. The loss is shown to be within ±2 dBs from the exact response for one kilometer link in highly humid environment. Therefore, its accuracy is even much better in the case of usually considered shorter range future B5G wireless systems.
