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 public safe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intergovernmental Organizations
An international organization or international organisation (see spelling differences), also known as an intergovernmental organization or an international institution, is a stable set of norms and rules meant to govern the behavior of states and other actors in the international system. Organizations may be established by a treaty or be an instrument governed by international law and possessing its own legal personality, such as the United Nations, the World Health Organization and NATO. 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. Notable examples include the United Nations (UN), Organization for Security and Co-operation in Europe (OSCE), Bank for International Settlements (BIS), Council of Europe (COE), International Labour Organization (ILO) and International Crim ...

Wireless LAN
A wireless LAN (WLAN) is a wireless computer network A wireless network is a computer network that uses wireless data connections between network nodes. Wireless networking is a method by which homes, telecommunications networks and business installations avoid the costly process of introducing c ... 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Switched Mesh
A switched mesh is a wireless mesh network that uses multiple radios to communicate via dedicated mesh backhaul links to each neighboring node in the mesh. Here all of the available bandwidth of each separate radio channel is dedicated to the link to the neighboring node. The total available bandwidth is the sum of the bandwidth of each of the links. 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. 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. A switched mesh node uses separate access and multiple mesh backhaul radios. There are three distinct types of configuration of wireless mesh networking products in the market today: *''single radio shared mesh'' - in the first type one radio provides both backhaul (packet relaying) and client services (access to a laptop). *''du ...

Municipal Broadband
Municipal broadband is broadband Internet access owned by public entities. Services are often provided either fully or partially by local governments to residents within certain areas or jurisdictions. Common connection technologies include unlicensed wireless (Wi-Fi, wireless mesh networks), licensed wireless (such as WiMAX), and fiber optic cable. Many cities that previously deployed Wi-Fi based solutions, likComcastanCharter Spectrum are switching to municipal broadband. Municipal fiber-to-the-home networks are becoming more prominent because of increased demand for modern audio and video applications, which are increasing bandwidth requirements by 40% per year. Supporters of municipal broadband argue that when cities create their own internet and broadband, customers ultimately get faster internet speeds, lower prices, and better customer service than from internet service providers. The purpose of municipal broadband is to provide internet access to those who cannot afford inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesh Networking
A mesh network is a local area network topology in which the infrastructure 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/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 infrastructure neighbours are hierarchical. While star-and-tree topologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IEEE 802
IEEE 802 is a family of Institute of Electrical and Electronics Engineers (IEEE) standards for local area networks (LAN), personal area network (PAN), and metropolitan area networks (MAN). 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 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 for standards projects. ...

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 target ...

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

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 In general, every telecommunications network conceptually c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
