Measurements To Support Public Safety Communications

Excerpt from Measurements to Support Public Safety Communications: Attenuation and Variability of 750 Mhz Radio Wave Signals in Four Large Building Structures This is the sixth in a series of nist technical notes (tn) on propagation and detection of radio signals in large building structures (apartment complex, hotel, office buildings, sports stadium, shopping mall, etc). The first, second, and third nist Tech Notes (nist TN 1540, nist TN 1541, and nist TN 1542) described experiments related to radio propagation in a structure before, during, and after implosion. The next two Tech Notes (nist TN 1545 and nist TN 1546) focused exclusively on RF propagation into large buildings, with no implosion results. These reports are intended to give first responders and system designers a better understanding of what to expect from the radio-propagation environment in disaster situations. The overall goal of this project is to create a large, public-domain data set describing the attenuation and variability of radio signals in various building types in the public safety frequency bands.

Excerpt from Measurements to Support Modulated-Signal Radio Transmissions for the Public-Safety Sector This is the fifth in a series of nist Technical Notes (tn) on propagation and detection of radio signals in large building structures. This series has been developed to support improved radio communications for the public-safety community in difficult radio environments. The first, second, and third nist Technical Notes (nist TN 1540, 1541, and 1542) described experiments that measured received signal strength in structures before, during, and after implosion. The fourth, nist Technical Note 1545, describes a series of signal-strength measurements carried out in 14 large public buildings. The first four Technical Notes have created a large, public-domain data set describing the attenuation of radio signals in various building types for the public safety and cellular telephone bands. The present document augments this work by providing additional data that are relevant to modulated-signal communication measurement and simulation for the public-safety sector. We describe measurements of three large public buildings and one subterranean tunnel. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Every day in cities and towns across the Nation, emergency response personnel respond to incidents of varying scope and magnitude. Their ability to communicate in real time is critical to establishing command and control at the scene of an emergency, to maintaining event situational awareness, and to operating overall within a broad range of incidents. However, as numerous after-action reports and national assessments have revealed, there are still communications deficiencies that affect the ability of responders to manage routine incidents and support responses to natural disasters, acts of terrorism, and other incidents. Recognizing the need for an overarching emergency communications strategy to address these shortfalls, Congress directed the Department of Homeland Security's (DHS) Office of Emergency Communications (OEC) to develop the first National Emergency Communications Plan (NECP). Title XVIII of the Homeland Security Act of 2002 (6 United States Code 101 et seq.), as amended, calls for the NECP to be developed in coordination with stakeholders from all levels of government and from the private sector. In response, DHS worked with stakeholders from Federal, State, local, and tribal agencies to develop the NECP—a strategic plan that establishes a national vision for the future state of emergency communications. To realize this national vision and meet these goals, the NECP established the following seven objectives for improving emergency communications for the Nation's Federal, State, local, and tribal emergency responders: 1. Formal decision-making structures and clearly defined leadership roles coordinate emergency communications capabilities. 2. Federal emergency communications programs and initiatives are collaborative across agencies and aligned to achieve national goals. 3. Emergency responders employ common planning and operational protocols to effectively use their resources and personnel. 4. Emerging technologies are integrated with current emergency communications capabilities through standards implementation, research and development, and testing and evaluation. 5. Emergency responders have shared approaches to training and exercises, improved technical expertise, and enhanced response capabilities. 6. All levels of government drive long-term advancements in emergency communications through integrated strategic planning procedures, appropriate resource allocations, and public-private partnerships. 7. The Nation has integrated preparedness, mitigation, response, and recovery capabilities to communicate during significant events. The NECP also provides recommended initiatives and milestones to guide emergency response providers and relevant government officials in making measurable improvements in emergency communications capabilities. The NECP recommendations help to guide, but do not dictate, the distribution of homeland security funds to improve emergency communications at the Federal, State, and local levels, and to support the NECP implementation. Communications investments are among the most significant, substantial, and long-lasting capital investments that agencies make; in addition, technological innovations for emergency communications are constantly evolving at a rapid pace. With these realities in mind, DHS recognizes that the emergency response community will realize this national vision in stages, as agencies invest in new communications systems and as new technologies emerge.

An Assessment of the Communications Technology Laboratory at the National Institute of Standards and Technology: Fiscal Year 2019 is an independent technical assessment of the quality of the National Institute of Standards and Technology's (NIST's) Communications Technology Laboratory (CTL). It reviews the organization's technical programs, the portfolio of scientific expertise within the organization, the adequacy of the organization's facilities, equipment, and human resources, and the effectiveness by which the organization disseminates its program outputs. This report focuses on CTL priority areas such as public safety communications, trusted spectrum testing, and Next Generation Wireless (5G and Beyond). It also assesses the extent to which CTL applied the recommendations from a 2015 National Academies' report, which describes many of the critical uses of radio communications, provides lab-specific recommendations, and highlights important research priorities for the Boulder, Colorado communications technology laboratory of the Department of Commerce laboratory. This new report also describes the current activities of the Boulder telecommunications laboratories, its strengths and weaknesses as an organization, and its plans for the near future

This assessment of the technical quality and relevance of the programs of the Measurement and Standards Laboratories of the National Institute of Standards and Technology is the work of the 165 members of the National Research Council's (NRC's) Board on Assessment of NIST Programs and its panels. These individuals were chosen by the NRC for their technical expertise, their practical experience in running research programs, and their knowledge of industry's needs in basic measurements and standards. This assessment addresses the following: The technical merit of the laboratory programs relative to the state of the art worldwide; The effectiveness with which the laboratory programs are carried out and the results disseminated to their customers; The relevance of the laboratory programs to the needs of their customers; and The ability of the laboratories' facilities, equipment, and human resources to enable the laboratories to fulfill their mission and meet their customers' needs.
