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)
