Cloud RAN Orchestration and Management
The Orchestration and management for Cloud RAN (cRAN) is consist of a suite of Orchestration and OSS systems, including AI/ML advanced analytics systems, to automate the end-to-end service lifecycle starting […]
IEEE 1588: Precision Time Protocol (PTP) for Telecom Networks
Overview of IEEE 1588 PTP PTP is a network based time synchronization protocol, but instead of millisecond-level synchronization, PTP networks aim to achieve nanosecond or even picosecond-level synchronization. Synchronization is […]
