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 ...

Airphone Passenger Phone
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 designated 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 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, governmental, and private aircraft."''

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 exam ...

Reuters
Reuters ( ) is a news agency owned by Thomson Reuters Corporation. It employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Reuters is one of the largest news agencies in the world. The agency was established in London in 1851 by the German-born Paul Reuter. It was acquired by the Thomson Corporation of Canada in 2008 and now makes up the media division of Thomson Reuters. History 19th century Paul Reuter worked at a book-publishing firm in Berlin and was involved in distributing radical pamphlets at the beginning of the Revolutions in 1848. These publications brought much attention to Reuter, who in 1850 developed a prototype news service in Aachen using homing pigeons and electric telegraphy from 1851 on, in order to transmit messages between Brussels and Aachen, in what today is Aachen's Reuters House. Reuter moved to London in 1851 and established a news wire agency at the London Royal Exchange. Headquartered in London, R ...

US Airways
US Airways (formerly USAir) was a major United States airline that operated from 1937 until its merger with American Airlines in 2015. It was originally founded in Pittsburgh as a mail delivery airline called All American Aviation, which soon became a commercial passenger airline. In 1953, it was renamed Allegheny Airlines and operated under that name for a quarter-century. In October 1979, after the passage of the Airline Deregulation Act, Allegheny Airlines changed its name to USAir. A decade later it had acquired Piedmont Airlines and Pacific Southwest Airlines (PSA), and was one of the U.S.'s seven transcontinental legacy carriers. In 1997, it rebranded as US Airways. The airline had an extensive international and domestic network, with 193 destinations in 24 countries in North America, South America, Europe, and the Middle East. The airline was a member of the Star Alliance, before becoming an affiliate member of Oneworld in March 2014. US Airways had 343 mainline j ...

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 controlli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
