The 3rd Generation Partnership Project (3GPP) is a consortium of telecommunication standards organisations that develop and maintain standards for mobile telecommunications systems. It is made up of seven national or regional telecommunication standards organizations that serve as primary members, along with a variety of other organizations that serve as associate members. The consortium organises its work into three different areas: Radio Access Networks, Services and Systems Aspects, and Core Network and Terminals.
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. It is known for its work on GSM and related 2G, 2.5G, and 2.75G standards, including GPRS and EDGE; UMTS and related 3G standards, including HSPA and HSPA+; LTE and related 4G standards, including LTE Advanced and LTE Advanced Pro; 5G NR and related 5G standards, including 5G-Advanced.
