LTE-A
LTE Advanced, also named or recognized as LTE+, LTE-A or 4G+, is a 4G mobile Cellular network, cellular communication standard developed by 3GPP as a major enhancement of the LTE (telecommunication), Long Term Evolution (LTE) standard. Three technologies from the LTE-Advanced tool-kit carrier aggregation, 4x4 MIMO and 256QAM modulation in the downlink if used together and with sufficient aggregated bandwidth, can deliver maximum peak downlink speeds approaching, or even exceeding, 1 Gbit/s. This is significantly more than the peak 300 Mbit/s rate offered by the preceding LTE standard. Later developments have resulted in LTE Advanced Pro (or 4.9G) which increases bandwidth even further. The first ever LTE Advanced network was deployed in 2013 by SK Telecom in South Korea. In August 2019, the Global mobile Suppliers Association (GSA) reported that there were 304 commercially launched LTE-Advanced networks in 134 countries. Overall, 335 operators are investing in LTE-Adv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LTE (telecommunication)
In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for cellular mobile devices and data terminals. It is considered to be a "transitional" 4G technology, and is therefore also referred to as 3.95G as a step above 3G. LTE is based on the 2G GSM/ EDGE and 3G 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. LTE has been succeeded by LTE Advanced, which is officially defined as a "true" 4G technology and also named "LTE+". Terminology 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 the original version did not meet the technical criteria of a 4G wire ...

Tobago
Tobago, officially the Ward of Tobago, is an List of islands of Trinidad and Tobago, island and Regions and municipalities of Trinidad and Tobago, ward within the Republic of Trinidad and Tobago. It is located northeast of the larger island of Trinidad and about off the northeastern coast of Venezuela. It lies to the southeast of Grenada and southwest of Barbados. Etymology Tobago was named ''Belaforme'' by Christopher Columbus "because from a distance it seemed beautiful". The Spanish friar Antonio Vázquez de Espinosa wrote that the Kalina people, Kalina (mainland Caribs) called the island ''Urupina'' because of its resemblance to a big snail, while the Island Caribs, Kalinago (Island Caribs) called it ''Aloubaéra'', supposedly because it resembled the ''alloüebéra'', a giant snake which was supposed to live in a cave on the island of Dominica. The earliest known record of the use of the name ''Tabaco'' to refer to the island is a Spanish royal order issued in 1511. ...

DC-HSPA+
Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication, and extends the original HSPA. The 3GPP standard organisation specified the original HSPA in release 7. HSPA+ can achieve data rates of up to 42.2 Mbit/s. HSPA+ upgrades existing 3G networks to achieve speeds closer to 4G without a new radio interface. HSPA+ should not be confused with LTE, which uses an air interface based on orthogonal frequency-division modulation and multiple access. HSPA+ introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beamforming focuses antenna power in a beam toward the user's direction. MIMO uses multiple antennas on the sending and receiving side. Further releases of the standard have introduced dual carrier operation, allowing communication over two 5 MHz frequency bands simultaneously. Advanced HSPA+ is a further evolution of HSPA and provides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3G Network
3G refers to the third-generation of cellular network technology. These networks were rolled out beginning in the early 2000s and represented a significant advancement over the second-generation ( 2G), particularly in terms of data transfer speeds and mobile internet capabilities. The major 3G standards are UMTS (developed by 3GPP, succeeding GSM) and CDMA2000 (developed by Qualcomm, succeeding cdmaOne); both of these are based on the IMT-2000 specifications established by the International Telecommunication Union (ITU). While 2G networks such as GPRS and EDGE supported limited data services, 3G introduced significantly higher-speed mobile internet and enhanced multimedia capabilities, in addition to improved voice quality. It provided moderate internet speeds suitable for general web browsing and multimedia content including video calling and mobile TV, supporting services that provide an information transfer rate of at least 144 kbit/s. Later 3G releases, often referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HD Voice
Wideband audio, also known as wideband voice or HD voice, is high definition voice quality for telephony audio, contrasted with standard digital telephony "toll quality". It extends the frequency range of audio signals transmitted over telephone lines, resulting in higher quality speech. The range of the human voice extends from 100 Hz to 17 kHz but traditional, voiceband or narrowband telephone calls limit audio frequencies to the range of 300 Hz to 3.4 kHz. Wideband audio relaxes the bandwidth limitation and transmits in the audio frequency range of 50 Hz to 7 kHz. In addition, some wideband codecs may use a higher audio bit depth of 16 bits to encode samples, also resulting in much better voice quality. Wideband codecs have a typical sample rate of 16 kHz. For superwideband codecs the typical value is 32 kHz. History In 1987, the International Telecommunication Union (ITU) standardized a version of wideband audio known as G.722. Radio ...
