LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. LTE is also called 3.95G and has been marketed as "4G LTE" and "Advanced 4G"; but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series for LTE Advanced. The requirements were set forth by the ITU-R organisation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LTE Advanced
LTE Advanced (LTE+) is a mobile communication standard and a major enhancement of the LTE (telecommunication), Long Term Evolution (LTE) standard. It was formally submitted as a candidate 4G to ITU-T in late 2009 as meeting the requirements of the IMT-Advanced standard, and was standardized by the 3rd Generation Partnership Project (3GPP) in March 2011 as 3GPP Release 10. The LTE+ format was first proposed by NTT DoCoMo of Japan and has been adopted as the international standard. LTE standardization has matured to a state where changes in the specification are limited to corrections and bug fixes. The first commercial services were launched in Sweden and Norway in December 2009 followed by the United States and Japan in 2010. More LTE networks were deployed globally during 2010 as a natural evolution of several 2G and 3G systems, including Global system for mobile communications (GSM) and Universal Mobile Telecommunications System (UMTS) in the 3GPP family as well as CDMA2000 in ...

Compaq LTE
Compaq LTE was a line of laptop computers made by Compaq, introduced in 1989. The first models, Compaq LTE and Compaq LTE 286, were among the first computers to be close to the size of a paper notebook, spurring the use of the term "notebook" to describe a smaller laptop, and earned a notable place in laptop history. They were also among the first to include both a built-in hard disk and a floppy disk drive, and later models offered optional docking stations, providing performance comparable to then-current desktop machines. History Compaq introduced the LTE in 1989. At the time of launch, virtually no "notebook"-style fully-fledged computers existed. Prior to the LTE series, portable computers were bulky, such as Compaq SLT, which is coined as the predecessor to the LTE series, despite both models existing side by side for some time. Compaq SLT had large full-size 3.5-inch hard drives, and was heavy at 6.5 kg in comparison to the LTE at approximately 2.5 kg. Models ...

Letter To The Editor
A letter to the editor (LTE) is a Letter (message), letter sent to a publication about an issue of concern to the reader. Usually, such letters are intended for publication. In many publications, letters to the editor may be sent either through Mail, conventional mail or electronic mail. Letters to the editor are most frequently associated with newspapers and news magazines, however, they are sometimes published in other periodicals such as entertainment and technical magazines and #Academic, academic journals. Radio station, Radio and television station, television stations may also receive such letters, which are sometimes read on the air, particularly on news commentary broadcasts or on talk radio. In this presentation form the letter to the editor can also be described as viewer mail or listener mail, depending on the medium. Subject matter The subject matter of letters to the editor vary widely. However, the most common topics include: * Supporting or opposing a stance take ...

LTE International Airways
Lte International Airways S.A. (Lte Volar Airlines) was a Spanish charter airline based in Palma de Mallorca, Spain. It operated passenger charter services throughout Europe. Its main base was Son Sant Joan Airport, Palma de Mallorca with hubs at Tenerife South Airport, Gran Canaria Airport, Lanzarote Airport, Fuerteventura Airport and Josep Tarradellas Barcelona–El Prat Airport. History The airline was established on 29 April 1987 by Spanish businessmen and German LTU International. It started operations on 1 November 1987. From 1993 until May 2001, LTU was the sole owner having bought out the other original shareholders. On 24 May 2001, LTU sold the airline to a group of Spanish and Italian businessmen, including the Volare Group. As a result, LTE was rebranded Volar Airlines for two successive years 2003 and 2004. In 2005, the airline was renamed back to LTE International Airways. The airline was wholly owned by Gasarer. From July 2008, Lte operated flights betwe ...

Liquid Tension Experiment
Liquid Tension Experiment (LTE) is an American instrumental progressive metal supergroup, founded by Mike Portnoy, then Dream Theater's drummer, in 1997. The band has released two albums through Magna Carta Records. A third album, with the absence of John Petrucci was released in 2007 under the name "Liquid Trio Experiment". A live album with the absence of Jordan Rudess (mostly) was released in 2009 under the name "Liquid Trio Experiment 2". Three live albums and two videos were released in 2009 by the complete band. Active up until 1999, when Jordan Rudess formally joined Dream Theater, the band reunited in 2008 for a series of live shows, and eventually reconvened in 2020 to record a third studio album featuring all members of the band, which was released on April 16, 2021. History Formation, studio albums and tours Liquid Tension Experiment was formed by former Dream Theater drummer Mike Portnoy after Magna Carta gave him the green light for "whatever he wanted to do".

Local Thermodynamic Equilibrium
Thermodynamic equilibrium is an axiomatic concept of thermodynamics. It is an internal state of a single thermodynamic system, or a relation between several thermodynamic systems connected by more or less permeable or impermeable walls. In thermodynamic equilibrium, there are no net macroscopic flows of matter nor of energy within a system or between systems. In a system that is in its own state of internal thermodynamic equilibrium, no macroscopic change occurs. Systems in mutual thermodynamic equilibrium are simultaneously in mutual thermal, mechanical, chemical, and radiative equilibria. Systems can be in one kind of mutual equilibrium, while not in others. In thermodynamic equilibrium, all kinds of equilibrium hold at once and indefinitely, until disturbed by a thermodynamic operation. In a macroscopic equilibrium, perfectly or almost perfectly balanced microscopic exchanges occur; this is the physical explanation of the notion of macroscopic equilibrium. A thermodynamic sy ...

London Transport Executive
The London Transport Executive was the organisation responsible for public transport in Greater London, England between 1948 and 1962. In common with all London transport authorities from 1933 to 2000, the public name and operational brand of the organisation was London Transport. Formation On 1 January 1948, pursuant to the Transport Act 1947, the London Passenger Transport Board (LPTB) was nationalised and renamed the London Transport Executive (LTE), becoming a subsidiary organisation of the British Transport Commission, which was formed on the same day. Another subsidiary of the commission was the Railway Executive (which traded as British Railways), which meant that London Transport and the main-line railways were under the same management for the first and last time in their respective histories. Projects A great deal of the early work of the LTE was spent repairing and replacing stock and stations damaged during World War II. LTE also oversaw the completion of the d ...

Lifting-the-exponent Lemma
In elementary number theory, the lifting-the-exponent (LTE) lemma provides several formulas for computing the p-adic valuation \nu_p of special forms of integers. The lemma is named as such because it describes the steps necessary to "lift" the exponent of p in such expressions. It is related to Hensel's lemma. Background The exact origins of the LTE lemma are unclear; the result, with its present name and form, has only come into focus within the last 10 to 20 years.Pavardi, A. H. (2011).

Leukotriene
Leukotrienes are a family of eicosanoid inflammatory mediators produced in leukocytes by the oxidation of arachidonic acid (AA) and the essential fatty acid eicosapentaenoic acid (EPA) by the enzyme arachidonate 5-lipoxygenase. Leukotrienes use lipid signaling to convey information to either the cell producing them (autocrine signaling) or neighboring cells (paracrine signaling) in order to regulate immune responses. The production of leukotrienes is usually accompanied by the production of histamine and prostaglandins, which also act as inflammatory mediators. One of their roles (specifically, leukotriene D4) is to trigger contractions in the smooth muscles lining the bronchioles; their overproduction is a major cause of inflammation in asthma and allergic rhinitis. Leukotriene antagonists are used to treat these disorders by inhibiting the production or activity of leukotrienes.

Loss Of Tail-rotor Effectiveness
Loss of tail-rotor effectiveness (LTE)Rotorcraft Flying Handbook Section 11-12, Federal Aviation Administration, Skyhorse Publishing (July 2007) occurs when the tail rotor of a helicopter is exposed to wind forces that prevent it from carrying out its function—that of cancelling the torque of the engine and transmission. Any low-airspeed high-power environment provides an opportunity for it to occur. Causes Environmental factors which can lead to LTE include higher operating-density altitudes or temperatures, and high winds. A high gross weight can also create an LTE-conducive situation. Causative wind-directions may include: # Main rotor disk interference - Main-rotor disk vortices are pushed into the tail rotor by wind. This can occur with wind coming from 10 o'clock on North American (counter-clockwise) rotors and from 2 o'clock on clockwise rotors. The wind pushes the dirty air and vortices generated from the main-rotor into the tail-rotor, preventing the tail rotor fr ...
