GSM

Global System for Mobile CommunicationsGSM networkGSM (850/900/1800/1900)
The project was established in December 1998 with the goal of developing a specification for a 3G mobile phone system based on the 2G GSM system, within the scope of the International Telecommunication Union's International Mobile Telecommunications-2000.
Subsequently, the 3GPP developed third-generation (3G) UMTS standards, followed by fourth-generation (4G) LTE Advanced standards, which do not form part of the ETSI GSM standard.

5G

5G broadband5G NR5th generation mobile networks
The industry association 3GPP defines any system using "5G NR" (5G New Radio) software as, "5G", a definition that came into general use by late 2018.

LTE Advanced

LTE-ALTE-Advanced4G+
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.

A further improved 3GPP standard, Evolved High Speed Packet Access (also known as HSPA+), was released late in 2008 with subsequent worldwide adoption beginning in 2010.

LTE (telecommunication)

LTE4G LTETD-LTE
They are primarily Release 6 systems, but as of 2010, growing interest in HSPA+ and LTE is driving adoption of Release 7 and its successors.
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.

UMTS

WCDMAW-CDMATD-SCDMA
Developed and maintained by the 3GPP (3rd Generation Partnership Project), UMTS is a component of the International Telecommunications Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology.
