Distributed RAN
Centralized RAN
Virtualized RAN
Elastic RAN
› IP transport
› Low latency Ethernet (Fronthaul)
ECOC 2017 | © Ericsson AB 2017 | Page 8
› 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
CPRI as a Cornerstone of the RAN
