The OpenAirInterfaceTM (OAI) Software Alliance seeks contributions from the community to develop the different elements of 3GPP Stack (eNB, UE, Core Network).  Based on this design goal for the OAI Project, the development community will:

•    conform to all license requirements of the open source projects leveraged within the framework; and
•    operate to maximize opportunities for compatibility with other projects that might be leveraged in the framework.
