It seems like every mobile operator is exploring CRAN, trying to assess if baseband centralization will deliver on … WebThe CPRI standard defines an interface between the Radio Equipment Control (REC) and the Radio Equipment (RE), which is mostly used to carry data between cell sites and base stations. Since, CPRI was not designed to meet the timing, latency or efficiency requirements of 5G, eCPRI was developed specifically for 5G fronthaul transport.
WebJan 13, 2024 · CPRI is a point-to-point interface, meaning that vendors will be exclusive within their own network. Whereas eCPRI will be an open interface, making it easier for carriers to mix and match vendor equipment, allowing more convergence in the industry as carriers complement networks with shared equipment.
