Public Safety Network
Public safety agencies at various levels of government have joined together to share information and communicate when faced with public safety incidents. Interagency collaboration initiatives of this nature result in the creation of public safety networks. Public safety networks may originate at any level of government, and their user base may span a single or multiple geographies. Such a network of public safety agencies, supported by an information and communications technology infrastructure, emerges from the individual and collaborative behaviors of their member agencies. This description focuses on public safety networks in the United States. Public safety networks have received more attention and priority as the country deals with increasing threats from terrorism and natural disasters. Public safety networks are defined differently as seen from different perspectives. From an organizational systems perspective a public safety network is an information technology (IT) e ...

Public Safety
Public security or public safety is the prevention of and protection from events that could endanger the safety and security of the public from significant danger, injury, or property damage. It is often conducted by a state government to ensure the protection of citizens, persons in their territory, organizations, and institutions against threats to their well-being, survival, and prosperity. The public safety issues that a municipality, county, regional, or federal jurisdiction may handle include crimes (ranging from misdemeanors to felonies), structure fires, conflagrations, medical emergencies, mass-casualty incidents, disasters, terrorism, and other concerns. Public safety organizations are organizations that conduct public safety. They generally consist of emergency services and first responders such as law enforcement, fire services, emergency medical services, security forces, and military forces. They are often operated by a government, though some private p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intergovernmental Organizations
An international organization, also known as an intergovernmental organization or an international institution, is an organization that is established by a treaty or other type of instrument governed by international law and possesses its own legal personality, such as the United Nations, the Council of Europe, African Union, Mercosur and BRICS. International organizations are composed of primarily member states, but may also include other entities, such as other international organizations, firms, and nongovernmental organizations. Additionally, entities (including states) may hold observer status. Examples for international organizations include: UN General Assembly, World Trade Organization, African Development Bank, UN Economic and Social Council, UN Security Council, Asian Development Bank, International Bank for Reconstruction and Development, International Monetary Fund, International Finance Corporation, Inter-American Development Bank, United Nations Environment Programme ...

Wireless LAN
A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building. This gives users the ability to move around within the area and remain connected to the network. Through a Gateway (telecommunications), gateway, a WLAN can also provide a connection to the wider Internet. Wireless LANs based on the IEEE 802.11 standards are the most widely used computer networks in the world. These are commonly called Wi-Fi, which is a trademark belonging to the Wi-Fi Alliance. They are used for home and small office networks that link together laptop computers, printer (computing), printers, smartphones, Web TVs and gaming devices through a Wireless router, wireless network router, which in turn may link them to the Internet. Hotspot (Wi-Fi), Hotspots provided by routers at restaurants, coffee shops, hotels, libraries, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Switched Mesh
A switched mesh is a type of wireless mesh network that uses multiple dedicated radios to communicate between each neighboring node in the mesh via dedicated mesh backhaul links. Nodes in a switched mesh use separate access and backhaul radios. Each dedicated mesh link is on a separate channel, ensuring that forwarded traffic does not use any bandwidth from any other link in the mesh. At each mesh point, traffic is "switched" from one channel to the next, giving rise to the name. As a result, a switched mesh is capable of much higher capacities and transmission rates than a shared mesh and grows in capacity as nodes are added to the mesh. All of the available bandwidth of each separate radio channel is dedicated to the link to the neighboring node, meaning that total available bandwidth is the sum of the bandwidth of each of the links. Context in wireless mesh networking Switched mesh is one of three distinct types of configuration of wireless mesh networking products in the m ...

Municipal Broadband
A municipality is usually a single administrative division having municipal corporation, corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term ''municipality'' may also mean the governing body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special district (United States), special-purpose district. The English language, English word is derived from French language, French , which in turn derives from the Latin language, Latin , based on the word for social contract (), referring originally to the Latin communities that supplied Rome with troops in exchange for their own incorporation into the Roman state (granting Roman citizenship to the inhabitants) while permitting the communities to retain their own local governments (a limited autonomy). A municipality can be any political jurisdiction (area), jurisdiction, from a sovereign state s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesh Networking
A mesh network is a local area network network topology, topology in which the infrastructure Node (networking), nodes (i.e. bridges, switches, and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data to and from clients. This lack of dependency on one node allows for every node to participate in the relay of information. Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. The ability to self-configure enables dynamic distribution of workloads, particularly in the event a few nodes should fail. This in turn contributes to fault-tolerance and reduced maintenance costs. Mesh topology may be contrasted with conventional Star network, star/Fat tree, tree local network topologies in which the bridges/switches are directly linked to only a small subset of other bridges/switches, and the links between these infrastruct ...

IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LANs), personal area networks (PANs), and metropolitan area networks (MANs). The IEEE 802 LAN/MAN Standards Committee (LMSC) maintains these standards. The IEEE 802 family of standards has had twenty-four members, numbered 802.1 through 802.24, with a working group of the LMSC devoted to each. However, not all of these working groups are currently active. The IEEE 802 standards are restricted to computer networks carrying variable-size packets, unlike cell relay networks, for example, in which data is transmitted in short, uniformly sized units called cells. Isochronous signal networks, in which data is transmitted as a steady stream of octet (computing), octets, or groups of octets, at regular time intervals, are also outside the scope of the IEEE 802 standards. The number 802 has no significance: it was simply the next number in the sequence that the IEEE used fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emergency Communication System
An emergency communication system (ECS) is any system (typically computer-based) that is organized for the primary purpose of supporting one-way and two-way communication of emergency information between both individuals and groups of individuals. These systems are commonly designed to convey information over multiple types of devices, from signal lights to text messaging to live, streaming video, forming a unified communication system intended to optimize communications during emergencies. Contrary to emergency notification systems, which generally deliver emergency information in one direction, emergency communication systems are typically capable of both initiating and receiving information between multiple parties. These systems are often made up of both input devices, sensors, and output/communication devices. Therefore, the origination of information can occur from a variety of sources and locations, from which the system will disseminate that information to one or more targe ...

Information Systems
An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. From a sociotechnical perspective, information systems comprise four components: task, people, structure (or roles), and technology. Information systems can be defined as an integration of components for collection, storage and processing of data, comprising digital products that process data to facilitate decision making and the data being used to provide information and contribute to knowledge. A computer information system is a system, which consists of people and computers that process or interpret information. The term is also sometimes used to simply refer to a computer system with software installed. "Information systems" is also an academic field of study about systems with a specific reference to information and the complementary networks of computer hardware and software that people and organizations use to collect, filter, p ...

Communications Network
A telecommunications network is a group of nodes interconnected by telecommunications links that are used to exchange messages between the nodes. The links may use a variety of technologies based on the methodologies of circuit switching, message switching, or packet switching, to pass messages and signals. Multiple nodes may cooperate to pass the message from an originating node to the destination node, via multiple network hops. For this routing function, each node in the network is assigned a network address for identification and locating it on the network. The collection of addresses in the network is called the address space of the network. Examples of telecommunications networks include computer networks, the Internet, the public switched telephone network (PSTN), the global Telex network, the aeronautical ACARS network, and the wireless radio networks of cell phone telecommunication providers. Network structure this is the structure of network general, every telecommu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Interorganizational System
An interorganizational system (IOS) is a system between organizations, or "shared information system among a group of companies."A. Gunasekaran, Maqsood Sandhu (2010) ''Handbook on Business Information Systems.'' p. 773 The most common form of interorganizational system is electronic data interchange, which permits instantaneous computer-to-computer transfer of information. Overview Interorganizational systems allow the flow of information to be automated between organizations in order to reach a desired supply-chain management system, which enables the development of competitive organizations. This supports forecasting client needs and the delivery of products and services. Interorganizational system helps to better manage buyer-supplier relationships by encompassing the full depths of tasks associated with business processes company-wide.
