Standardizing Base Station Design with OBSAI and CPRI
More InfoLess Info
Each new wave of wireless networks has increasingly challenged vendors to cost-effectively produce base stations with more sophisticated enabling technologies, more flexible support of multiple radio standards, and more capacity to meet increasing traffic demands. In response to these issues, vendors are investing in the development of open standards for next generation base stations. This white paper seeks to introduce the audience to both Open Base Station Architecture Initiative (OBSAI) and Common Public Radio Interface (CPRI), and to provide a detailed description of how their standards can be applied in the development of new base stations. It also describes how CPRI and OBSAI are specifying the key interface technology that enables the exciting new RRH deployment topology.
