Fronthaul & SDN/NFV

vRAN impact on backhaul / transport network

Fronthaul throughputs and latency create dilemma:

• Upgrading the transport network or changing the fronthaul protocol/standard

Options on the table – not mutually exclusive:

• Dedicated WDM network to transport CPRI

• Next generation interface (CPRI evolution / functional split )

• Radio over Ethernet (CPRI encapsulation)

• Radio over Fiber (RoF)
