No part of the contents of this document may be disclosed, used or reproduced in any form, or by any means, without the prior written consent of Quotient Associates Ltd. ii EXECUTIVE SUMMARY Objective and scope Within industry and academia there is significant activity in research and development towards the next generation of mobile broadband technologies (5G). Coupled with this there is increasing interest in identifying the frequency bands that will be needed to deliver 5G services. At the moment there is no overall consensus on what 5G will actually be. Work in ITU-R (WP5D) is ongoing to develop a vision for 5G (IMT 2020) including identifying the target capabilities. It is, however, widely accepted that at least one element of 5G will require the use of spectrum bands at much higher frequencies than those that current mobile broadband technologies can make use of, e.g. bands above 6 GHz. A first step currently being discussed is a proposal for an agenda item for the World Radio Conference after next (WRC-19) to identify suitable high frequency spectrum for 5G in the ITU Radio Regulations. -

Pearson (California Institute of Technology), Scott Ransom (National Radio Astronomy Observatory), and Gregory B. Taylor (University of New Mexico) Abstract (optional): This Astro2020 APC white paper addresses state of the profession considerations regarding spectrum management for the protection of radio astronomy observations. Given the increasing commercial demand for radio spectrum, and the high monetary value associated with such use, innovative approaches to spectrum management will be necessary to ensure the scientific capabilities of current and future radio telescopes. Key aspects include development of methods, in both hardware and software, to improve mitigation and excision of radio frequency interference (RFI). In addition, innovative approaches to radio regulations and coordination between observatories and commercial -
Executive Summary of the ICAO Position for ITU WRC-15 Radio
Executive Summary of the ICAO Position for ITU WRC-15 Radio frequency spectrum is a scarce natural resource with finite capacity for which demand is constantly increasing. The requirements of civil aviation as well as other spectrum users continue to grow at a fast pace, thus creating an ever-increasing pressure to an already stretched resource. International competition between radio services obliges all spectrum users, aeronautical and non- aeronautical alike, to continually defend and justify retention of existing or addition of new frequency bands. The ICAO Position aims at protecting aeronautical frequency spectrum for all radiocommunication and radionavigation systems used for ground facilities and on board aircraft. The ICAO Position addresses all radioregulatory aspects on aeronautical matters on the agenda for the WRC-15. The items of main concern to aviation include the following: identification of additional frequency bands for the International Mobile Telecommunications (IMT). Under this agenda item, the telecommunications industry is seeking up to 1200 MHz of additional spectrum in the 300 MHz to 6 GHz range for mobile and broadband applications. It is expected that a number of aeronautical frequency bands will come under pressure for potential repurposing, especially some of the Primary Surveillance Radar (PSR) bands. Existing frequency allocations which are vital for the operation of aeronautical very small aperture terminal (VSAT) ground-ground communication networks, especially in tropical regions, are also expected to come under pressure. Due to decisions made by a previous WRC, this has already become a problematic issue in Africa. WRC-15 agenda items 1.1 and 9.1.5 refer; potential radioregulatory means to facilitate the use of non-safety satellite service frequency bands for a very safety-critical application, the command and control link for remotely piloted aircraft systems (RPAS) in non-segregated airspace. -
The Rights of Older Persons Within the African Union
The Rights of Older Persons within the African Union Prof. Israel (Issi) Doron,* Dr. Benny Spanier, and Mr. Ori Lazar Karere kagokurerawo (Look after it and it will look after you) Introduction Historically, the human rights of older persons,1 as a unique, separate, social group, have received little attention in the international discourse on human rights.2 This reality has begun to change in the last decade following a series of discussions,3 articles,4 and activities of nongovernmental organizations (NGOs). 5 In very recent years, this development has reached a climax with the establishment and activity of the United Nations Open Ended Working Group (OEWG) since 2010,6 and with the *The authors would like to acknowledge and thank the Minerva Center for Human Rights at the Hebrew University in Jerusalem for its support for this research project. Prof. Israel (Issi) Doron is the Head of the Department of Gerontology, University of Haifa, Haifa, Israel; Dr. Benny Spanier is an Israeli legal scholar which specializes in international elder law; Mr. Ori Lazar is a law student at the Faculty of Law, University of Haifa, Haifa, Israel. 1 The question who is an "older person" or what is the threshold for being "old" is a challenging question of its own. There are different legal and sociological approaches to answer this question. For the purposes of this article, the approach of the Chicago Declaration on the Rights of Older Persons will be adopted (Online: http://www.jmls.edu/braun/pdf/chicago-declaration-v11.pdf): "Article 10: Definitions: (a). For purposes of this Declaration, an “older person” is generally any person who due to chronological age or status is considered under local or national law to be an older person or is perceived as being an older person." 2 For a general overview of the historical lack of interest and attention to the human rights of older persons see: Diego Rodriguez-Pinzon & Claudia Martin, The International Human Rights Status of Elderly Persons, 18 Am. -

Abstract: A compact concentric structured monopole antenna for super wide band (SWB) applica- tions with triple notch band characteristics is designed and experimentally validated. The antenna covers an immense impedance bandwidth (1.6–47.5 GHz) with sharp triple notch bands at 1.8– 2.2 GHz, 4–7.2 GHz, and 9.8–10.4 GHz to eliminate interference from co-existing advanced wireless services (AWS), C bands, and X bands, respectively. By loading an E-shaped stub connected at the top of the patch and by etching a split elliptical slot at the lower end of the radiating patch, the band rejection characteristics from 1.8–2.2 GHz for the AWS and 4–7.2 GHz for the C band are achieved, Citation: Balani, W.; Sarvagya, M.; respectively. -

ATTACHMENT A to FCC Public Notice DA 20-1243 Recommendations presented at October 20, 2020, Meeting of the World Radiocommunication Conference Advisory Committee 1 Maritime Aeronautical and Radar Services 2 WAC-23/0009 IWG-1/007 (09.23.20) UNITED STATES OF AMERICA DRAFT PRELIMINARY VIEW ON WRC-23 AI 1.6 AGENDA ITEM 1.6: to consider, in accordance with Resolution 772 (WRC-19), regulatory provisions to facilitate radiocommunications for sub-orbital vehicles; ISSUE: The United States requires a stable regulatory framework for radiocommunications for sub-orbital vehicles. BACKGROUND: Sub-orbital vehicles must operate in the same airspace as conventional aircraft while transitioning to and from space. Stations on board sub-orbital vehicles have a need for voice/data communications, navigation, surveillance, and telemetry and tracking and command (TT&C) applications to safely and effectively complete various mission requirements. The current regulatory provisions and procedures for terrestrial and space services may or may not be adequate for international use of relevant frequency assignments by stations on board sub-orbital vehicles. Resolution 772 (WRC-19) calls for studying spectrum needs and appropriate modifications to the Radio Regulations to accommodate sub-orbital vehicle radiocommunications requirements, excluding any new allocations or changes to the existing allocations in Article 51. There are several U.S. Commercial Space Transportation industry and government initiatives that could benefit from modification of the Radio Regulations as a result of these technical, operational, and regulatory studies. U.S. VIEW: To pursue studies called for by Resolution 772 (WRC-19) as a basis for possible new Radio Regulations to support the growing radiocommunications needs of sub-orbital vehicles. -
