3rd Generation Partnership Project (3GPP) is an agreement between different telecommunications standards that was established in December 1998. The aim of 3GPP is to create a globally applicable technical system and report, based on the evolution of the third generation GSM networks and radio technology, which is used by them. The 3GPP working groups are, among other things, responsible for the specifications of the network protocols and the infrastructure of 2G – 5G networks (M2M, LTE M, NB-IOT).
