`THIRD GENERATION PARTNERSHIP
`PROJECT (3GPP)
`TM
`3GPP is a partnership project bringing together national
`Standards Development Organizations (SDOs) from around the
`globe initially to develop technical specifications for the 3rd
`generation of mobile, cellular telecommunications, UMTS.
`
`We took over the maintenance of the (2nd generation) GSM
`specifications already brought to maturity by ETSI TC SMG, and
`which had formed the basis for 3G development. We later
`instigated 4th generation mobile with LTE and more recently the
`5th generation, 5G. Technologies developed and maintained by
`3GPP include EDGE, HSPA, Carrier Aggregation, NR, EPC and
`NG-CN, descriptions of which can be found in the Technologies
`pages.
`
`3GPP now encompasses seven SDOs: ETSI (Europe and rest of
`world), ATIS (USA), ARIB and TTC (Japan), TTA (South Korea),
`CCSA (China) and TSDSI (India). Technical input comes from
`around 2000 delegates representing member organizations of
`these SDOs. ETSI provides the 20-person secretariat which
`coordinates some 140 meetings per year handling 100,000
`contribution documents. The running costs are divided amongst
`the SDOs, and a number of regional “Friends of 3GPP” groups
`fund the meetings in their respective regions.
