5G O-RAN Radio Unit

5G small-cells provide coverage where not supported by macro base stations. Femto solutions are optimized for power and cost.

The 5G Radio Unit is a special case of small-cell deployment where components of the L1 and L2 processing chain are implemented more centralized in a distributed unit (DU), connecting over 3GPP split 7-2x/split 6 or other mechanisms.
