C-RAN : the drivers & the challenges  The drivers     

Fast growth of wireless data Evolution towards collaborative radio TCO reduction : CAPEX & OPEX savings Energy efficiency Speed up / facilitate network deployment

 The challenges

 CPRI data rates : 2.5 Gbps for LR3, 9.8 Gbps for LR7  Lack of fiber everywhere & cost of the “very last mile”  Migration path from traditional network architecture to C-RAN
