WebCPRI is an interface that sends data from the RRUs to the baseband unit. “It’s a serial interface, which is a very high-speed connection, a way to translate all those radio … 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. WebC-RAN architecture, a large number of RRUs are con-nected to the BBU pool, which thus requires a large number of fi ber optic links. Our algorithm is designed to compress the digital signals and the bit width before CPRI framing and to do so without any unac-ceptable degradation in system performance. If we can achieve this goal, we can reduce ... WebSep 30, 2024 · Compared to CPRI, eCPRI reduces both latency and jitter for high-priority traffic and improves the efficiency of 5G fronthaul networks. The bandwidth requirement of the enhanced interface is also about one-tenth of CPRI’s. And, unlike CPRI, eCPRI’s traffic can be moved on Ethernet, an important attribute for the rise of open RAN. エヴァ 光柱
