- CPRI Specification V7.0 (gowin, xilinx)
- Layer 1 and Layer 2
- high-speed serial signal transmission between:
- Radio Equipment Control (REC)
- Remote Radio Equipment (RE)

A 2.5 Gbps CPRI link has the capacity to carry the equivalent of 40 MHz air bandwidth LTE IQ data which for instance can be used to carry a 2 time MIMO on a 20 MHz bandwidth.
eCPRI Specification V1.2 (2018-06-25)) протокола eCPRI (evolved CPRI)
В отличие от CPRI, спецификация eCPRI поддерживает большую гибкость в реализации функционального разделения ресурсов базовой станции на блоки.
Стоит отметить, что спецификации интерфейса eCPRI и CPRI обратно не совместимы.
