Distributed RAN

Centralized RAN

Virtualized RAN

Elastic RAN

› IP transport

› Low latency Ethernet (Fronthaul)


› CPRI is the Common Public Radio Interface

– Key component of “fronthaul”

› Radio waveform digitized and sent over fiber

– Antenna is simply elements and a DAC

– Waveform generation occurs deeper in the network

› 10x increase in bandwidth requirements

– Very strict latency & jitter

› Enabler of control components co-location

– Concept of a baseband hotel

› This eliminates latency and allows very tight

coordination of multiple radios
