Book Description
The World Radiocommunication Conference (WRC) is a meeting of official delegations from over 140 nations and is organized by the International Telecommunication Union (ITU). Delegates meet every few years to negotiate proposals to changes in international radio spectrum regulations; changes that would be enforced by the ITU internationally if approved. Proposals are brought up during a WRC and then negotiated at the next WRC. The time in between each WRC allows for national governments to work internally and with their regional counterparts to develop a consensus position on each proposal. The consensus position can then be presented at the next WRC. Each proposal is referred to as an agenda item and agenda items are specific and propose narrow yet potentially substantial changes to the use of the spectrum that can have significant impact on its users. Most agenda items support the active use of the spectrum, so it is important for vulnerable, passive services to voice their concerns about potentially adverse effects on their operations. Two U.S. passive services, the passive Radio Astronomy Service (RAS) and the Earth Exploration-Satellite Service (EESS), provide scientific observations of the universe and Earth through the use of advanced receiver technology with extreme sensitivity and the employment of complex noise reduction algorithms. Even with such technology, RAS and EESS are seriously adversely affected by what most active services would consider extremely low noise levels. Views of the U.S. NAS and NAE on Agenda Items at Issue at the World Radiocommunication Conference 2015 present the NAS and NAE\'s views on agenda items that affect RAS and EESS. This report includes a list of each agenda item, how it affects the programs, and the committee\'s recommendations.

Book Description
The radio frequency spectrum is a limited resource with ever increasing demand from an expansive range of applicationsâ€"all the way from commercial, such as mobile phones, to scientific, such as hurricane monitoring from space. Since radio waves do not stop at national borders, international regulation is necessary to ensure effective use of the radio spectrum for all parties. Every 2 to 5 years, the International Telecommunication Union convenes a World Radiocommunication Conference (WRC) to review and revise the international radio regulations. This report provides guidance to U.S. spectrum managers and policymakers as they prepare for the WRC in 2019. While the resulting document is targeted primarily at U.S. agencies dealing with radio spectrum issues, other Administrations and foreign scientific users may find its recommendations useful in their own WRC planning.

Book Description
The passive, receive-only Radio Astronomy Service (RAS) and the Earth Exploration-Satellite Service (EESS) provide otherwise impossible scientific observations of the Universe and Earth through the use of advanced receiver technology with extreme sensitivity and the employment of complex noise reduction algorithms. Even with such technology, RAS and EESS are quite adversely affected by what most active services would consider low noise levels. To ensure their ability to use the radio spectrum for scientific purposes, scientists must be party to the discussion in the lead-up to the World Radiocommunication Conference (WRC), which will next be held in January and February 2012 in Geneva, Switzerland. By request of the National Science Foundation and the National Aeronautics and Space Administration, the National Research Council was convened to provide guidance to the U.S. spectrum managers and policymakers as they prepare for the WRC in order to protect the scientific exploration of the Earth and Universe using the radio spectrum. While the resulting document is targeted at U.S. agencies, representatives of foreign governments and foreign scientific users will find its contents useful as they plan their own WRC positions.

Book Description
Addressing a field that has been dominated by astronomers, physicists, engineers, and computer scientists, the contributors to this collection raise questions that may have been overlooked by physical scientists about the ease of establishing meaningful communication with an extraterrestrial intelligence. These scholars are grappling with some of the enormous challenges that will face humanity if an information-rich signal emanating from another world is detected. By drawing on issues at the core of contemporary archaeology and anthropology, we can be much better prepared for contact with an extraterrestrial civilization, should that day ever come.

Book Description
How can we meet the special needs of children for emergency medical services (EMS) when today's EMS systems are often unprepared for the challenge? This comprehensive overview of EMS for children (EMS-C) provides an answer by presenting a vision for tomorrow's EMS-C system and practical recommendations for attaining it. Drawing on many studies and examples, the volume explores why emergency care for childrenâ€"from infants through adolescentsâ€"must differ from that for adults and describes what seriously ill or injured children generally experience in today's EMS systems. The book points the way to integrating EMS-C into current emergency programs and into broader aspects of health care for children. It gives recommendations for ensuring access to emergency care through the 9-1-1 system; training health professionals, from paramedics to physicians; educating the public; providing proper equipment, protocols, and referral systems; improving communications among EMS-C providers; enhancing data resources and expanding research efforts; and stimulating and supporting leadership in EMS-C at the federal and state levels. For those already deeply involved in EMS efforts, this volume is a convenient, up-to-date, and comprehensive source of information and ideas. More importantly, for anyone interested in improving the emergency services available to childrenâ€"emergency care professionals from emergency medical technicians to nurses to physicians, hospital and EMS administrators, public officials, health educators, children's advocacy groups, concerned parents and other responsible adultsâ€"this timely volume provides a realistic plan for action to link EMS-C system components into a workable structure that will better serve all of the nation's children.

Book Description
The electromagnetic spectrum is a vital part of our environment. Measures of radio frequency emissions from natural phenomena enable both practical applications, such as weather predictions and studies of the changing of Earth's climate here at home, and reveal the physical properties of cosmic sources. The spectrum is therefore a resource to be used wisely now and to be protected for future generations. Handbook of Frequency Allocations and Spectrum Protection for Scientific Uses: Second Edition sets forth the principles for the allocation and protection of spectral bands for services using the radio spectrum for scientific research. This report describes the radio frequency bands used by scientific services and includes relevant regulatory information and discussion of scientific use of frequency bands. This reference will guide spectrum managers and spectrum regulatory bodies on science issues and serve as a resource to scientists and other spectrum users.
