Layered Model Of Regulation
The layered model of telecommunication regulation is a proposal for nascent US telecommunication public policies that mimic the horizontal characteristics of Internet Protocol communication and the OSI model. Advocates of layered telecommunication policies argue that current US regulations are not longer appropriate for new information technologies as functionally similar services (such as DSL and cable modems) are not governed by a common set of rules but instead subject to separate regulatory systems written for each distinct media type such as the telephone or cable television systems. The layered policy model proposes a regulatory system that classifies technologies based on their common layered characteristics instead of regulating each communication technology with a disparate set of rules. Horizontal policy advocates argue that this modular approach to regulation promotes competition by forcing all telecommunication services to adhere to a uniform set of characteristic-bas ...

Internet Protocol
The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in 1974, which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol (TCP). The Internet protocol suite is therefore often referred to as ''TCP/IP''. The first major version of IP, Internet Protocol Version 4 (IPv4), is the do ...

OSI Model
The Open Systems Interconnection model (OSI model) is a conceptual model that 'provides a common basis for the coordination of SOstandards development for the purpose of systems interconnection'. In the OSI reference model, the communications between a computing system are split into seven different abstraction layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application. The model partitions the flow of data in a communication system into seven abstraction layers to describe networked communication from the physical implementation of transmitting bits across a communications medium to the highest-level representation of data of a distributed application. Each intermediate layer serves a class of functionality to the layer above it and is served by the layer below it. Classes of functionality are realized in all software development through all and any standardized communication protocols. Each layer in the OSI model has its own well-defined functi ...

Cable Modems
A cable modem is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fibre-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet, taking advantage of the high bandwidth of a HFC and RFoG network. They are commonly deployed in the Americas, Asia, Australia, and Europe. History MITRE Cablenet Internet Experiment Note (IEN) 96IEN 96 - The Cablenet Project (1979) describes an early RF cable modem system. From pages 2 and 3 of IEN 96: T ... |
Telephone Network
A telephone network is a telecommunications network that connects telephones, which allows telephone calls between two or more parties, as well as newer features such as fax and internet. The idea was revolutionized in the 1920s, as more and more people purchased telephones and used them to communicate news, ideas, and personal information. During the 1990s, it was further revolutionized by the advent of computers and other sophisticated communication devices, and with the use of dial-up internet. There are a number of different types of telephone network: * A landline network where the telephones must be directly wired into a single telephone exchange. This is known as the public switched telephone network or PSTN. * A wireless network where the telephones are mobile and can move around anywhere within the coverage area. * A private network where a closed group of telephones are connected primarily to each other and use a gateway to reach the outside world. This is usually us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable Television System
Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables, or in more recent systems, light pulses through fibre-optic cables. This contrasts with broadcast television (also known as terrestrial television), in which the television signal is transmitted over-the-air by radio waves and received by a television antenna attached to the television; or satellite television, in which the television signal is transmitted over-the-air by radio waves from a communications satellite orbiting the Earth, and received by a satellite dish antenna on the roof. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation. A "cable channel" (sometimes known as a "cable network") is a television ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Telecommunications Policy Of The United States
The telecommunications policy of the United States is a framework of law directed by government and the regulatory commissions, most notably the Federal Communications Commission (FCC). Two landmark acts prevail today, the Communications Act of 1934 and the Telecommunications Act of 1996. The latter was intended to revise the first act and specifically to foster competition in the telecommunications industry. Aims In the name of public interest, a large proportion of telecommunications policy is concerned with the economic regulation of interstate and international communication. This includes all communication by radio, telephone, wire, cable and satellite. Telecommunications policy outlines antitrust laws as is common for industries with large barriers to entry. Other features of the policies addressed include common carrier laws which controls access to networks. While the telephone providers are required to be common carriers, there is an ongoing net neutrality debate about t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
