Technologies Home
The whole 3GPP web site is full of technology, the idea of having a ‘Technology’ part of the site is to provide some pointers on the features that are built in to the 3GPP specifications.


At the bottom (Right hand side) of each page on the 3GPP web site, there is a list of some keywords and acronyms, where an article has been written to provide some background material on the topic. There is also a Keywords page that contains further links to pages about specific technologies.

3GPP Series

Some technologies can be [at least partially] aligned with a 3GPP series  (See the full list of spec. series at: https://www.3gpp.org/specifications/specification-numbering )

Technical terms

The 3GPP Report ‘Vocabulary for 3GPP Specifications’ identifies specialist technical terms used within the 3GPP;

  • To ensure that editors use terminology that is consistent across specifications.
  • To provide a reader with convenient reference for technical terms that are used across multiple documents.
