5G

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
