O-RAN Fronthaul Transport Security using MACsec

Daniel Dik Sep 14 2022, 5G provides a range of improvements compared to existing 4G LTE mobile networks in regards to capacity, speed, latency and security. One of the main improvements is in the 5G RAN; it is based on a virtualized architecture where functions can be centralized close to the 5G core for economy or distributed as close to the edge as possible for lower latency performance. The functional split options for the baseband station processing chain results in a separation between...
