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 -
Radio Spectrum a Key Resource for the Digital Single Market
Briefing March 2015 Radio spectrum A key resource for the Digital Single Market SUMMARY Radio spectrum refers to a specific range of frequencies of electromagnetic energy that is used to communicate information. Applications important for society such as radio and television broadcasting, civil aviation, satellites, defence and emergency services depend on specific allocations of radio frequency. Recently the demand for spectrum has increased dramatically, driven by growing quantities of data transmitted over the internet and rapidly increasing numbers of wireless devices, including smartphones and tablets, Wi-Fi networks and everyday objects connected to the internet. Radio spectrum is a finite natural resource that needs to be managed to realise the maximum economic and social benefits. Countries have traditionally regulated radio spectrum within their territories. However despite the increasing involvement of the European Union (EU) in radio spectrum policy over the past 10 to 15 years, many observers feel that the management of radio spectrum in the EU is fragmented in ways which makes the internal market inefficient, restrains economic development, and hinders the achievement of certain goals of the Digital Agenda for Europe. In 2013, the European Commission proposed legislation on electronic communications that among other measures, provided for greater coordination in spectrum management in the EU, but this has stalled in the face of opposition within the Council. In setting out his political priorities, Commission President Jean-Claude Juncker has indicated that ambitious telecommunication reforms, to break down national silos in the management of radio spectrum, are an important step in the creation of a Digital Single Market. The Commission plans to propose a Digital Single Market package in May 2015, which may again address this issue. -
PSAD-79-48A an Unclassified Version of a Classified Report
STUDYBY THE STAFFOF THE‘U.S. General Accounting Office An Unclassified Version Of A Classified Report Entitled “The Navy’s Strategic Communications Systems--Need For Management Attention And Decisionmaking” Peacetime communications systems provide reliable day-to-day communications to the strategic submarine force. However, the Navy’s most survivable wartime communica- tions link to nuclear-powered strategic submarines--the TACAMO aircraft--has cer- tain problems which need attention. Also, the Navy should reconsider whether another peacetime communications system--the extremely low frequency system--is needed. COMPTROLLER GENERAL OF THE UNITED STATES WASHINGTON. O.C. 20548 B-168707 To the President of the Senate and the Speaker of the House of Representatives This report is an unclassified version of a SECRET report (PSAD-79-48, March 19, 1979) to the Congress that describes the various communications systems used by our strategic submarine force and questions the need for the extremely low frequency system. Also, the report addresses the need for support of the TACAMO comnunications system. We made this study because of widespread congressional interest in strategic communications systems, especially the TACAMO and proposed extremely low frequency systems. These issues are receiving increased recognition, and the Navy plans to spend millions of dollars to improve the TACAMO system and conduct research and development on the extremely low frequency system. Copies of this report are being sent to the Secretary of Defense and the Secretary of the Navy.

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. -

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. -
