EJL Wireless Research Releases Industry Leading Analysis on the Common Public Radio Interface (CPRI™) 6.0 Specification

The complex nature of the CPRI™ subsystem components and its ecosystem is analyzed, revealing the symbiotic relationship between Serial RapidIO® (sRIO) and CPRI™ technology



Simply put, CPRI™ is Fronthaul and Fronthaul is CPRI™

EJL Wireless Research predicts the CPRI™ ecosystem will enter into a furious development phase in 2015 as next the generation of sRIO products become available. Simply put, CPRI™ is Fronthaul and Fronthaul is CPRI™, and only sRIO meets its requirements. The CPRI™ ecosystem entails silicon chips, test equipment including emulators, generators, protocol analyzers, LTE software, fiber optic modules, EDA tools and IP in the form of synthesizable core, verification IP, and system/chip emulators, and timing components.

“During the course of our extensive research into the specification and the entire CPRI™ ecosystem it spawned, we uncovered an incredible mix of interdependencies between application specific integrated circuits (ASICs), field programmable gate arrays (FPGAs), and other components that comprise a CPRI™ subsystem. Several important technology standards and interlinked component parts result in a tightly woven matrix that allows CPRI™ to scale-up to fully support LTE-A, -B, and 4.5G.

There are clear signs that some in the industry would like to alter CPRI™ defined Fronthaul so it can encapsulate CPRI™ as Ethernet payload to create all internet protocol (IP) Fronthaul CPRI™ over Ethernet (CoE) networks. While CapEx and OpEx may eventually cause a shift and migration towards Ethernet, we do not believe this will occur within the next five years, unless a CPRI™-specific-version of Ethernet evolves to fully meet CPRI™ requirements,” says Principal Analyst, Cary Snyder.

“This report is the first of a series covering CPRI™ and CPRI™-related technologies that EJL Wireless Research will be publishing throughout 2015. I am very excited to have Cary on the team and focusing on this very important wireless topic,” says Earl Lum, Founder and President.
