Key 3GPP Specifications

The 50 most important 3GPP specifications, selected based on how frequently they are referenced by other documents. These form the foundation of modern telecommunications standards.

Selection Methodology

These specifications were selected using citation analysis - we analyzed all cross-references between 3GPP documents to identify which specifications are most frequently cited by others. A high reference count indicates that a specification is:

  • Foundational - defines core concepts used across the ecosystem
  • Widely implemented - referenced by many dependent specifications
  • Essential reading - understanding it helps understand many other specs

Specifications with Evolution badge have AI-generated analysis showing how they evolved across 3GPP releases, highlighting key changes and growth in scope.
