DC-HSPA+
Evolved High Speed Packet Access, HSPA+, HSPA (Plus) or HSPAP, is a technical standard for wireless broadband telecommunication. It is the second phase of HSPA which has been introduced in 3GPP release 7 and being further improved in later 3GPP releases. HSPA+ can achieve data rates of up to 42.2 Mbit/s. It introduces antenna array technologies such as beamforming and multiple-input multiple-output communications (MIMO). Beam forming focuses the transmitted power of an antenna in a beam towards the user's direction. MIMO uses multiple antennas at the sending and receiving side. Further releases of the standard have introduced dual carrier operation, i.e. the simultaneous use of two 5 MHz carriers. HSPA+ is an evolution of HSPA that upgrades the existing 3G network and provides a method for telecom operators to migrate towards 4G speeds that are more comparable to the initially available speeds of newer LTE networks without deploying a new radio interface. HSPA+ should no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voice Over NR
VoNR or 'Voice over New Radio' (also referred to as Voice over 5G or Vo5G) is a 5G high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables. VoNR fully utilizes the 5G Standalone (SA) core and can have better voice quality than its predecessor Voice over Long Term Evolution (VoLTE). Call setup time is faster than VoLTE due to the inherent lower latency of 5G NR. 5G VoNR removes the LTE anchor allowing the voice call to stay on a 5G network. VoNR calls are usually charged at the same rate as other calls. To be able to make a VoNR call, the device, its firmware, and the mobile telephone provider must all support the service in the area, and be able to work together.

5G NR
5G NR (New Radio) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks. As with 4G (LTE), it is based on OFDM. The 3GPP specification 38 series provides the technical details behind 5G NR, the successor of LTE. The study of NR within 3GPP started in 2015, and the first specification was made available by the end of 2017. While the 3GPP standardization process was ongoing, the industry had already begun efforts to implement infrastructure compliant with the draft standard, with the first large-scale commercial launch of 5G NR having occurred in the end of 2018. Since 2019, many operators have deployed 5G NR networks and handset manufacturers have developed 5G NR enabled handsets. Frequency bands 5G NR uses frequency bands in two frequency ranges: # Frequency Range 1 (FR1), for bands within 410 MHz – 7125 MHz # Frequency Range 2 (FR2), for band ...

Voice Over LTE
Voice over LTE (VoLTE) is an LTE high-speed wireless communication standard for mobile phones and data terminals, including Internet of things (IoT) devices and wearables. VoLTE has up to three times more voice and data capacity than older 3G UMTS and up to six times more than 2G GSM. It uses less bandwidth because VoLTE's packet headers are smaller than those of unoptimized VoIP/LTE. VoLTE calls are usually charged at the same rate as other calls. To be able to make a VoLTE call, the device, its firmware, and the mobile telephone provider must all implement the service in the area, and be able to work together. VoLTE has been marketed as HD Voice by some carriers, but this is not the same as the VoLTE standard. Moreover, HD+ (EVS) is what actually is used only in LTE; HD Voice was available in 3G too. Overview VoLTE is based on the IP Multimedia Subsystem (IMS) architectural framework, with specific profiles for control and media planes of voice service. This facilitate ...

LTE Advanced
LTE Advanced (LTE+) is a mobile communication standard and a major enhancement of the 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 the 3GPP2 family.

3GPP Long Term Evolution
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 organis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
