Airfone
Airfone was an air-ground radiotelephone service developed by MCI founder John D. Goeken, and operated under the names ''Airfone'', ''GTE Airfone'', and Verizon Airfone. Airfone allowed passengers to make telephone calls (later including data modem service) in-flight. Airfone handsets were often located in the middle airliner seatbacks, with two handsets per row for 6-wide coach seating configurations, and more or less depending on the aircraft layout and fare class. First class cabins typically had one handset per seat. Some planes had one or more bulkhead mounted phone stations with cordless handsets that the passengers could use, instead of the multiple wired handsets. Airfone phone calls were usually quite expensive compared to ground-based telephone calls, costing $3.99 per call and $4.99 per minute in 2006. The original Airfone main office and network operations center are located at 2809 Butterfield Rd, Oak Brook, Illinois. The network operations center remains at this l ...

Western Union
The Western Union Company is an American multinational financial services company, headquartered in Denver, Colorado. Founded in 1851 as the New York and Mississippi Valley Printing Telegraph Company in Rochester, New York, the company changed its name to the Western Union Telegraph Company in 1856 after merging with several other telegraph companies. The company dominated the American telegraphy industry from the 1860s to the 1980s, pioneering technology such as telex and developing a range of telegraph-related services (including wire money transfer) in addition to its core business of transmitting and delivering telegram messages. After experiencing financial difficulties, Western Union began to move its business away from communications in the 1980s and increasingly focused on its money transfer services. The company ceased its communications operations completely in 2006, at which time The New York Times described it as "the world's largest money-transfer business" and ...

Air-ground Radiotelephone Service
Air-ground radiotelephone service is a system which allows voice calls and other communication services to be made from an aircraft to either a satellite or land based network. The service operates via a transceiver mounted in the aircraft on frequency assignment authority, designated frequency, frequencies. In the US these frequencies have been allocated by the Federal Communications Commission. The system is used in both commercial and general aviation services. Licensees may offer a wide range of telecommunications services to passengers and others on aircraft. Design A U.S. air-ground radiotelephone transmits a radio signal in the 849 to 851 Hertz, megahertz range; this signal is sent to either a receiving ground station or a communications satellite depending on the design of the particular system. ''"Commercial aviation air-ground radiotelephone service licensees operate in the 800 MHz band and can provide communication services to all aviation markets, including commercial ...

Network Operations Center
A network operations center (NOC, pronounced like the word ''knock''), also known as a "network management center", is one or more locations from which network monitoring and control, or network management, is exercised over a computer, telecommunication or satellite network. __TOC__ History The earliest NOCs started during the 1960s. A Network Control Center was opened in New York by AT&T in 1962 which used status boards to display switch and routing information, in real-time, from AT&T's most important toll switches. AT&T later replaced this Network Control Center with a modernized NOC in 1977, located in Bedminster, New Jersey. Purpose NOCs are implemented by business organizations, public utilities, universities, and government agencies that oversee complex networking environments that require high availability. NOC personnel are responsible for monitoring one or many networks for certain conditions that may require special attention to avoid degraded service. Organization ...

Bandwidth (signal Processing)
Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies. It is typically measured in hertz, and depending on context, may specifically refer to ''passband bandwidth'' or ''baseband bandwidth''. Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum. Baseband bandwidth applies to a low-pass filter or baseband signal; the bandwidth is equal to its upper cutoff frequency. Bandwidth in hertz is a central concept in many fields, including electronics, information theory, digital communications, radio communications, signal processing, and spectroscopy and is one of the determinants of the capacity of a given communication channel. A key characteristic of bandwidth is that any band of a given width can carry the same amount of information, regardless of where that band is located in the frequency spectrum. For example, a ...

Continental Airlines
Continental Airlines, simply known as Continental, was a major United States airline founded in 1934 and eventually headquartered in Houston, Texas. It had ownership interests and brand partnerships with several carriers. Continental started out as one of the smaller carriers in the United States, known for its limited operations under the regulated era that provided very fine, almost fancy, service against the larger majors in important point-to-point markets, the largest of which was Chicago/Los Angeles. However, deregulation in 1978 changed the competitive landscape and realities, as noted by Smithsonian Airline Historian R. E. G. Davies, "Unfortunately, the policies that had been successful for more than forty years under (Robert) Six's cavalier style of management were suddenly laid bare as the cold winds of airline deregulation changed all the rules—specifically, the balance between revenues and expenditures." In 1981, Texas International Airlines acquired a controllin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
