Foundations, not 6G specifications

6G mobility watch

This site does not yet track 6G (IMT-2030) study items or schedules, because they have not been checked against 3GPP documents. This page lists only what the Rel-19 specifications already define for mobility.

For 6G itself, use 3GPP's own work-plan and meeting reports. When this site adds 6G content, it will cite the specific 3GPP document for each statement.
