Introduction to Space BSS and FSS Plans in ITU-R Procedures Introduction to the Space Plans (BSS and FSS) of the Radio Regulations 1 The fundamentals: ITU Constitution Article 44 Radio frequencies and any associated orbits are limited natural resources. Must be used rationally, efficiently and economically in conformity with the Radio Regulations. To have equitable access to those resources. Article 45 Must not cause harmful interference to a service operating in accordance with the Radio Regulations. The mechanism to control interference is within the Radio Regulations (RR) which contains: The allocation of frequency bands and services. The process of Coordination / Planning. The technical and operational limits to apply to avoid interference. It is used during: Licensing of frequencies and orbital locations. Monitoring the frequency emissions over a territory. Two Approaches to Regulation in the Radio Regulations Coordination Approach Planning Approach (subject of presentations about so-called (subject of this presentation) “non-plan”) It is a distribution of some of the It is a “First come, first served” spectrum/orbit resources based on approach based on current technical current and future technical requirements for operation. requirements It can be an efficient and Provides equitable access as each ITU economical approach for the first to Member State gets a pre-determined use it. As the spectrum/orbit is a allocation of part of the spectrum/orbit limited resource, late comers may not resources protected from harmful have access to it as the early users interference for current and future use. have consumed it all. However, it can be argued that it may not be as efficient and economical as it may prevent access to a part of that limited resource to others having the current capability to use it. Planning Approach the “Space Plans” The Space Plans have been established for certain space services and frequency bands in order to facilitate equitable access to a certain part of the frequency/orbit resource. Broadcasting-Satellite Fixed Satellite Service and feeder-link Plans Service Plans 11.7-12.2 GHz (Region 3), 4.5 - 4.8 GHz, 11.7-12.5 GHz (Region 1), 6.725 - 7.025 GHz, 10.7 - 10.95 GHz 12.2-12.7 GHz (Region 2), 11.2 - 11.45 GHz, 17.3-18.1 GHz (Region 1&3), 12.75 - 13.25 GHz 17.3-17.8 GHz (Region 2), 14.5-14.8 GHz (Region 1&3 except Europe) Cf.

Ap.30/30A: Ku Band (12 & 17 GHz) Ap30B: C Band & Ku Band Space Plans features (3/4) Protection from harmful interference is provided based on the Plan characteristics and NOT on the characteristics entered into the Master Register at notification stage. This is different for networks operating in the non-plan frequency bands.

  • 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.

    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.

Microwave hazards.S-matrix – significance, formulation and properties.S-matrix representation of a multi port network, S-matrix of a two port network with mismatched load. 1.1 INTRODUCTION Microwaves are electromagnetic waves (EM) with wavelengths ranging from 10cm to 1mm. The corresponding frequency range is 30Ghz (=109 Hz) to 300Ghz (=1011 Hz) . This means microwave frequencies are upto infrared and visible-light regions. The microwaves frequencies span the following three major bands at the highest end of RF spectrum. i) Ultra high frequency (UHF) 0.3 to 3 Ghz ii) Super high frequency (SHF) 3 to 30 Ghz iii) Extra high frequency (EHF) 30 to 300 Ghz Most application of microwave technology make use of frequencies in the 1 to 40 Ghz range. During world war II , microwave engineering became a very essential consideration for the development of high resolution radars capable of detecting and locating enemy planes and ships through a Narrow beam of EM energy. The common characteristics of microwave device are the negative resistance that can be used for microwave oscillation and amplification.
