Abstract：OpenAirInterface, or OAI, platform, which is an open-source software-based platform, was proposed to emulate a whole process of LTE system spanning full protocol stack of 3GPP standard. The platform--usually comprises of an OAI eNB, an OAI EPC and several OAI UEs--has great potential for operators to deploy new services/application in an ever-changing fast paced cellular networks, since it can significantly reduce CAPEX and OPEX. As a cost-effective means, it provides powerful support for the research of other related LTE technologies. In this article, state-of-the-art research on OAI platform are surveyed, and other technologies based on the platform, such as MIMO and C-RAN, are introduced. In particular, we discuss both of the software and hardware requirements when establish an OAI platform. As for each component of the whole network, we display how they configure and run under the Linux operating system. At the end of the article, we show three examples of application based on a testbed we design including two OAI UEs and an OAI eNB, from which the performance gain of LTE is well demonstrated.
