O-RAN testing and integration challenges

Integration and Fronthaul Challenges

While O-RAN promises are compelling, real-world deployment faces significant challenges. Multi-vendor integration complexity grows exponentially — N vendors means N×(N-1)/2 test combinations, and each vendor implements specs slightly differently. End-to-end responsibility is unclear when problems arise. Fronthaul requirements add another challenge: open fronthaul demands strict latency under 100 microseconds one-way, and synchronization accuracy within ±1.5 microseconds for TDD. Not all transport networks can meet these requirements, especially fiber-constrained sites. A system integrator…
