The seventeenth session of the Administrative Council of the International Telecommunication Union (ITU) was held from May 5 to June 9, 1962, under the chairmanship of Mr. Juan Antonio Autelli (Argentina). ITU's Secretary-General, Mr. Gerald C. Gross, remarked that the activities of the Union during the past year had continued to increase usefully on a sound financial basis. In discussing the work of ITU in the future, the Secretary-General stated that the efforts being taken by some nations to penetrate outer space constituted one of the greatest intellectual and technical enterprises in human history. ITU's role in this effort would be particularly important.

Rf Spectrum

Abstract As hundreds of new small satellites are being launched each year, the RF spectrum for satellite communication becomes increasingly occupied. The International Telecommunication Union recognized this problem at World Radiocommunication Conference 2015 (WRC-15) and invited study groups to investigate the utilization of frequency allocations. The studies followed a three-step approach: first, the TT&C spectrum requirements of small satellites, being a new class of satellites, were assessed. Second, the utilization of existing TT&C frequency allocations and their potential to incorporate the future number of satellites was studied. Third, the study groups investigated new potential TT&C frequency allocations in the frequency ranges 150.05–174 MHz and 400.15–420 MHz. The studies were completed for WRC-19. This paper presents the results of the study groups. A study of the spectrum requirements of small satellites has been completed. The required spectrum for TT&C was estimated to be less than 2.5 MHz for downlink and less than 1 MHz for uplink. Consequently, the study groups conducted sharing studies in various bands which yield that no new allocations are suitable for small satellite TT&C on a co-channel sharing basis. However, regulatory measures are proposed that in the study groups’ view will satisfy the small satellite developers’ needs. The paper will summarize the regulatory measures taken after WRC-19 along with a personal appraisal of the author.

Broad Audience

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.

The eighth plenary assembly of the International Radio Consultative Committee (CCIR) was held in Warsaw from August 9 to September 13, 1956, under the chairmanship of Professor Pawel Szulkin (Poland). The assembly elected with an absolute majority Dr. E. Metzler (Switzerland) as Director. The assembly considered a report which dealt with the activities of the fourteen established study groups as well as proposals to reorganize the study groups. The Warsaw decisions modifying procedures experimentally for the future were the outcome of proposals by the Organization and Finance Committees, the CCIR Secretariat and of discussions of the problem in the plenary assembly. The study groups were to remain the same in number and the allocation of work was in general the same, though it was felt desirable to give a more precise definition of their terms of reference. Among the resolutions adopted by the assembly, a number dealt with the length, content and quantity of documents submitted to the chairmen of the study groups, emphasizing that these should be as short as possible, as few as possible and that they should contain only the minimum indispensable mathematical formulae or numerical and experimental data. The new system was also expected to improve the position of distant countries which had so far experienced great difficulty in receiving preliminary documentation in sufficient time before plenary assemblies. The Technical Assistance Committee recommended the creation of a joint CCIR-International Telegraph and Telephone Consultative Committee (CCITT) committee to consider the ways and means whereby technical assistance was at present granted and to make suggestions for improvements, as far as telecommunication was concerned, to the ITU Administrative Council.

Abstract The geostationary orbit is a special area in outer space. Because of its distinctive characteristics, it has constantly been the subject of economic and political desirability. Space powers, taking advantage of their technological superiority and rules applied by the International Telecommunication Union (ITU) retained a privileged position. Developing countries, responding to this state of affairs, have taken a number of measures to improve their positions. Some of them posed a challenge to the main regulation of space law (Bogota declaration was an attempt to exercise a national sovereignty over the segments of the geostationary orbit), some are based on the use of the legal gaps in ITU regulations. Given these circumstances, the specific case of geostationary belt contributes to the debate on the regulations governing space exploration.
