Welcome to the OpenAirInterface project

EURECOM has created the OpenAirInterface (OAI) Software Alliance (OSA), a separate legal entity from EURECOM, which aims to provide an open-source ecosystem for the core (EPC) and access-network (EUTRAN) protocols of 3GPP cellular systems with the possibility of interoperating with closed-source equipment in either portion of the network. In addition to the huge economic success of the open-source model, the Alliance will be a tremendous tool used by both industry and academia. More importantly it will ensure a much-needed communication mechanism between the two in order to bring academia closer to complex real-world systems which are controlled by major industrial players in the wireless industry. In the context of the evolutionary path towards 5G, there is clearly the need for open-source tools to ensure a common R&D and prototyping framework for rapid proof-of-concept designs.

The OSA's EPC software is known and openairCN while the access-network software goes under the name of openair5G. OAI currently includes a standard-compliant implementation of a subset of Release 10 LTE for UE, eNB, MME, HSS, SGw and PGw on standard Linux-based computing equipment (Intel x86 PC/ARM architectures). Openair5G is freely distributed by the OSA under the terms stipulated by a new open-source license catering to the intellectual property agreements used in 3GPP which allows contributions from 3GPP members holding patents on key procedures used in the standard. OpenairCN is distributed under an Apache V2.0 license, in order to ease with integration within an OpenStack environment. The team is working closely with ETSI to harmonize the software license with the intellectual property policy of 3GPP. The software can be used in conjunction with standard RF laboratory equipment available in many labs (i.e. National Instruments/Ettus USRP and PXIe platforms), in addition to custom RF hardware provided by EURECOM, to implement these functions to a sufficient degree to allow for real-time interoperation with commercial devices. Some industrial users have reported integration with commercial RF remote radio-head equipment.

The current major industrial users of OAI for collaborative projects are Alcatel-Lucent, China Mobile, TCL, Thales, National Instruments, Orange, Intel, TCS, Canonical, Ercom, Keysight, Telekom Malaysia, Telecom Italia, Swisscom, ARELIS (Thomson Broadcast). Leading research centers using and contributing to the software development include B-COM, Fraunhofer IIS, Frauhofer FOKUS, IMST, TNO, Winlab, Idaho National Laboratory, III, ITRI, INDT, Fundacion Sadosky and many top university labs worldwide.
