OAI is based on a PC hosted software radio frontend architecture. operators in the world and are expected to rule the cellular land- scape at least for the current decade. They will also form the With OAI, the transceiver functionality is realized via a software starting point for further progress beyond the current generation radio front end connected to a host computer for processing. This of mobile cellular networks to chalk a path towards fifth generation approach is similar to other software-defined radio (SDR) proto- mobile networks. The lack of open cellular ecosystem has lim- typing platforms in the wireless networking research community ited applied research in this field within the boundaries of vendor such as SORA [3]. Other similar approaches combining PCs and and operator RD groups. Furthermore, several new approaches FPGA-based processing make use of NI LabVIEW software [4] or and technologies are being considered as potential elements mak- using the WARP [5] architecture.
