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 -
Chapter 4, Current Status, Knowledge Gaps, and Research Needs Pertaining to Firefighter Radio Communication Systems
NIOSH Firefighter Radio Communications CHAPTER IV: STRUCTURE COMMUNICATIONS ISSUES Buildings and other structures pose difficult problems for wireless (radio) communications. Whether communication is via hand-held radio or personal cellular phone, communications to, from, and within structures can degrade depending on a variety of factors. These factors include multipath effects, reflection from coated exterior glass, non-line-of-sight path loss, and signal absorption in the building construction materials, among others. The communications problems may be compounded by lack of a repeater to amplify and retransmit the signal or by poor placement of the repeater. RF propagation in structures can be so poor that there may be areas where the signal is virtually nonexistent, rendering radio communication impossible. Those who design and select firefighter communications systems cannot dictate what building materials or methods are used in structures, but they can conduct research and select the radio system designs and deployments that provide significantly improved radio communications in this extremely difficult environment.4 Communication Problems Inherent in Structures MULTIPATH Multipath fading and noise is a major cause of poor radio performance. Multipath is a phenomenon that results from the fact that a transmitted signal does not arrive at the receiver solely from a single straight line-of-sight path. Because there are obstacles in the path of a transmitted radio signal, the signal may be reflected multiple times and in multiple paths, and arrive at the receiver from various directions along various paths, with various signal strengths per path. In fact, a radio signal received by a firefighter within a building is rarely a signal that traveled directly by line of sight from the transmitter. -

Global Maritime Distress and Safety System (GMDSS) Handbook 2018 I CONTENTS
FOREWORD This handbook has been produced by the Australian Maritime Safety Authority (AMSA), and is intended for use on ships that are: • compulsorily equipped with GMDSS radiocommunication installations in accordance with the requirements of the International Convention for the Safety of Life at Sea Convention 1974 (SOLAS) and Commonwealth or State government marine legislation • voluntarily equipped with GMDSS radiocommunication installations. It is the recommended textbook for candidates wishing to qualify for the Australian GMDSS General Operator’s Certificate of Proficiency. This handbook replaces the tenth edition of the GMDSS Handbook published in September 2013, and has been amended to reflect: • changes to regulations adopted by the International Telecommunication Union (ITU) World Radiocommunications Conference (2015) • changes to Inmarsat services • an updated AMSA distress beacon registration form • changes to various ITU Recommendations • changes to the publications published by the ITU • developments in Man Overboard (MOB) devices • clarification of GMDSS radio log procedures • general editorial updating and improvements. Procedures outlined in the handbook are based on the ITU Radio Regulations, on radio procedures used by Australian Maritime Communications Stations and Satellite Earth Stations in the Inmarsat network. Careful observance of the procedures covered by this handbook is essential for the efficient exchange of communications in the marine radiocommunication service, particularly where safety of life at sea is concerned. Special attention should be given to those sections dealing with distress, urgency, and safety. Operators of radiocommunications equipment on vessels not equipped with GMDSS installations should refer to the Marine Radio Operators Handbook published by the Australian Maritime College, Launceston, Tasmania, Australia. No provision of this handbook or the ITU Radio Regulations prevents the use, by a ship in distress, of any means at its disposal to attract attention, make known its position and obtain help. -

ATTACHMENT a to FCC Public Notice DA 20-1243 Recommendations Presented at October 20, 2020, Meeting of the World Radiocommunicat
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. -
