PRAN: Programmable Radio Access Networks

  title={PRAN: Programmable Radio Access Networks},
  author={Wenfei Wu and Erran L. Li and Aurojit Panda and Scott Shenker},
With the continued exponential growth of mobile traffic and the rise of diverse applications, the current LTE radio access network (RAN) architecture of cellular operators face mounting challenges. Current RAN suffers from insufficient radio resource coordination, inefficient infrastructure utilization, and inflexible data paths. We present the high level design of PRAN, which centralizes base stations' L1/L2 processing into a cluster of commodity servers. PRAN uses a flexible data path model… CONTINUE READING
