  • OAI UE is tested in S1 and noS1 modes with USRP board
  • Multi-RRU TDD mode
  • X2 Handover in FDD mode

v1.0.3 -> June 2019.

• Bug fix for LimeSuite v19.04.0 API

v1.0.2 -> February 2019.

v1.0.1 -> February 2019.

• Bug fix for the UE L1 simulator.

v1.0.0 -> January 2019.

This version first implements the architectural split described in the following picture.

• Only FAPI, nFAPI and IF4.5 interfaces are implemented.
• Repository tree structure prepares future integrations of features such as LTE-M, nbIOT or 5G-NR.
• Preliminary X2 support has been implemented.
• S1-flex has been introduced.
• New tools: config library, telnet server, ...
• A lot of bugfixes and a proper automated Continuous Integration process validates contributions.

Old Releases:

• v0.6.1 -> Mostly bugfixes. This is the last version without NFAPI.
• v0.6 -> RRH functionality, UE greatly improved, better TDD support, a lot of bugs fixed.
