Understanding 5G ORAN

5G ORAN is an open and interoperable approach to building and operating radio access networks (RANs). Unlike traditional RAN architectures, which are typically vendor-specific and closed, ORAN promotes a multi-vendor ecosystem with standardized interfaces and modular components. This openness allows network operators to mix and match hardware and software from different vendors, fostering innovation and reducing costs.

ORAN consists of several key components:

  • Radio Units (RUs): These handle the radio frequency functions and are responsible for transmitting and receiving signals to and from user devices.

  • Distributed Units (DUs): These perform real-time processing functions such as coding/decoding and beamforming.

  • Centralized Units (CUs): These handle non-real-time functions, including mobility management and session management.

By disaggregating these functions, ORAN allows for more flexible and efficient network deployments, paving the way for advanced 5G use cases.

Importance of 5G ORAN Training

As 5G networks become more widespread, the demand for skilled professionals who understand ORAN architecture and can implement and manage these networks is growing rapidly. Training in 5G ORAN equips professionals with the knowledge and skills needed to:
