Generations of Mobile Standards

Release 1999

The first Release of the third generation specifications was essentially a consolidation of the underlying GSM specifications and the development of the new UTRAN radio access network. The foundations were laid for future high-speed traffic transfer in both circuit switched and packet switched modes.

Details of the features and work items under each 3GPP Release are kept in the corresponding, on-line, list of features and study items.

A comprehensive review of the Release 1999 features is held in the Summary of all Release 99 Features document
