Middle Mile
In the broadband Internet industry, the "middle mile" is the segment of a telecommunications network linking a network operator's core network to the local network plant, typically situated in the incumbent telco's central office (British English: telephone exchange) that provides access to the local loop, or in the case of cable television operators, the local cable modem termination system. This includes both the backhaul network to the nearest aggregation point, and any other parts of the network needed to connect the aggregation point to the nearest point of presence on the operator's core network. The term ''middle mile'' arose to distinguish this part of the network from the '' last mile'', which means the local links which provide service to the retail customer or end user, such as the local telephone lines from the telephone exchange or the coaxial cables from which connect to the customer's equipment. Middle-mile provision is a major issue in reducing the price of bro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadband Internet
In telecommunications, broadband or high speed is the wide- bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber, wireless Internet (radio), twisted pair cable, or satellite. Originally used to mean 'using a wide-spread frequency' and for services that were analog at the lowest level, nowadays in the context of Internet access, 'broadband' is often used to mean any high-speed Internet access that is seemingly always 'on' and is faster than dial-up access over traditional analog or ISDN PSTN services. The ideal telecommunication network has the following characteristics: ''broadband'', ''multi-media'', ''multi-point'', ''multi-rate'' and economical implementation for a diversity of services (multi-services). The Broadband Integrated Services Digital Network (B-ISDN) was planned to provide these characte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Network Architecture
Network architecture is the design of a computer network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as communication protocols used. In telecommunications, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated. The network architecture of the Internet is predominantly expressed by its use of the Internet protocol suite, rather than a specific model for interconnecting networks or nodes in the network, or the usage of specific types of hardware links. OSI model The Open Systems Interconnection model (OSI model) defines and codifies the concept of layered network architecture. Abstraction layers are used to subdivide a communications system further into smaller man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Loop Unbundling
Local loop unbundling (LLU or LLUB) is the regulatory process of allowing multiple telecommunications operators to use connections from a telephone exchange to the customer's location. The physical wire connection between the local exchange and the customer is known as a "local loop" and is owned by the incumbent local exchange carrier (also referred to as the "ILEC", "local exchange", or in the United States, either a " Baby Bell" or an independent telephone company). To increase competition, other providers are granted unbundled access. Policy background LLU is generally opposed by ILECs, which are generally either former investor-owned (North America) or state-owned monopoly enterprises. ILECs argue that LLU amounts to regulatory taking, which causes them to be compelled to provide competitors with business inputs, so they believe that LLU stifles infrastructure-based competition and technical innovation because new entrants prefer to use the incumbent's network instead of b ...

Forced Access Regulation
In the context of infrastructure, open access involves physical infrastructure such as railways and physical telecommunications network plants being made available to clients other than owners, for a fee. For example, private railways within a steel works are private and not available to outsiders. In the hypothetical case of the steelworks having a port or a railway to a distant mine, outsiders might want access to save having to incur a possibly large cost of building their own facility. Marconi and radio communication The Marconi Company was a pioneer of long distance radio communication, which was particularly useful for ships at sea. Marconi was very protective about its costly infrastructure and refused—except for emergencies—to allow other radio companies to share its infrastructure. Even if the message sender was royalty, as in the ''Deutschland'' incident of 1902, they continued to refuse access. Since radio communication was so new, it preceded laws, regulations ...

Last Mile (transportation)
In supply chain management and transportation planning, the last mile or last kilometer is the last leg of a journey comprising the movement of passengers and goods from a transportation hub to a final destination. The concept of "last mile" was adopted from the telecommunications industry, which faced difficulty connecting individual homes to the main telecommunications network. Similarly, in supply chain management, the last mile describes the logistical challenges at the last phase of transportation getting people and packages from hubs to their final destinations. Last-mile delivery is an increasingly studied field as the number of business-to-consumer (b2c) deliveries grow, especially from e-commerce companies in freight transportation, and ride-sharing companies in personal transportation. Some challenges of last-mile delivery include minimizing cost, ensuring transparency, increasing efficiency, and improving infrastructure. History "Last mile" was originally use ...

NRECA
The National Rural Electric Cooperative Association (NRECA) represents the interests of over 900 electric cooperatives in the United States. Cooperatives are not-for-profit and are owned by their membership. Founded in 1942, NRECA unites the country's generation, transmission, and distribution cooperatives found in 47 states, serving over 40 million people. It is headquartered in Arlington, Virginia, and since 2016 its CEO has been former U.S. Congressman Jim Matheson. Electric cooperatives serve 12 percent of the nation's population, yet own 42 percent of America's distribution lines covering three-quarters of the country. Currently, over 90% of electric cooperatives include renewable generation in their portfolios, receiving 11 percent of their total power from renewable sources compared to 8 percent for the entire utility sector. In December 2020, co-ops under NRECA won $1.6 billion from the FCC's Rural Digital Opportunity Fund to provide rural broadband service to approximat ...

Fiber Unbundling
Fiber (spelled fibre in British English; from ) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers have some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: * Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utility Pole
A utility pole, commonly referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, optical fiber, fiber optic cable, and related equipment such as Distribution transformer, transformers and street lights while depending on its application. They are used for two different types of power lines: ''sub transmission lines'', which carry higher voltage power between substations, and ''distribution lines'', which distribute lower voltage power to customers. Electrical wires and cables are routed overhead on utility poles as an inexpensive way to keep them insulated from the ground and out of the way of people and vehicles. Utility poles are usually made out of wood, Aluminium alloy, aluminum alloy, metal, concrete, or composites like fiberglass. A Stobie pole is a multi-purpose pole made of two ...

Common Utility Duct
A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics, cable television, and telephone cables are also sometimes carried. One may also be referred to as a services tunnel, services trench, services vault, or cable vault. Smaller cable containment is often referred to as a cable duct or underground conduit. Direct-buried cable is a major alternative to ducts or tunnels. Usage Utility tunnels are common in very cold climates where direct burial below the frost line is not feasible (such as in Alaska, where the frost line is often more than below the surface, which is frozen year round). They are also built in places where the water table is too high to bury water and sewer mains, and where utility poles would be too unsightly or pose a danger (like in earthquake prone Tokyo). Tunnels are also built to avoid t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
