3 Outline Introduction of 3GPP Overview 3GPP 5G Standard Status of Satellite related Activities in 3GPP 3

4 What is 3GPP? UMTS targeted a universal mobile standard European Telecommunication Standardization Institute is limited to European companies 3G Partnership Project was founded in 1998 A collaborative agreement between Standards Development Organizations (SDOs) and other bodies ARIB (Japan), CCSA (China), ETSI (Europe), ATIS (USA), TTA (Korea), TTC (Japan), TSDSI (India) Within scope of Intern. Mobile Telecommunication (IMT) project of Intern. Telecommunication Union (ITU) 3GPP produces and maintains specifications for: 2G, 3G, 4G, 5G and corresponding core networks and services 4
