Best Selenium Automation Training Institute in Bangalore – Selenium Labs

5G NR (New Radio) and ORAN (Open Radio Access Network) are two key technologies shaping modern mobile networks, but they serve different purposes.

5G NR (New Radio)

• Definition: 5G NR is the global standard for 5G wireless communication, developed by 3GPP.

• Key Features:

• Supports low, mid, and high (mmWave) frequency bands for better coverage and capacity.

  • Enables enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC).

  • Uses advanced technologies like beamforming, massive MIMO, and dynamic spectrum sharing (DSS).

  • Works with both Standalone (SA) and Non-Standalone (NSA) architectures.

ORAN (Open Radio Access Network)

• Definition: ORAN is an open, disaggregated approach to building mobile networks, promoted by the O-RAN Alliance.

• Key Features:

  • Allows interoperability between equipment from different vendors.

  • Uses open interfaces and virtualized network functions.

  • Enables RAN intelligence and automation through AI/ML.

  • Reduces costs and increases flexibility by separating hardware and software.

5G NR & ORAN Together

• ORAN can be used to deploy 5G NR networks in a more flexible and cost-efficient manner.

• Open interfaces in ORAN help integrate multi-vendor 5G NR components.

• Operators benefit from virtualized RAN (vRAN) and cloud-native architectures.

Selenium Labs helps the participants to get hands-on knowledge in telecom training with this course. And to make this course even more professional, we allow them to work in different real-time projects that include some real-time cases. Therefore, after completing this course, the participants can get complete expertise in both of these topics with practical exposure. Apart from that, the projects on which the students work here comply with the modules offered in the course curriculum.
