5G TESTING

Testing regimes for the new frequencies and features of 5G ROHDE AND SCHWARZ

Measurements taking place in pre-commercial 5G network trials provide new insights and overcome uncertainties before the technology’s formal launch.

How 5G is evolving

THE 3RD GENERATION Partnership Project (3GPP) defined fifthgeneration (5G) cellular technology in Release 15, which updated mission-critical (MC) communications and MC service functions, to meet the International Telecommunication Union’s IMT-2020 performance requirements. IMT-2020

latency communications (URLLC), and massive machine type communications (mMTC). Some of the 5G performance requirements spelled out are a 20 Gbps peak data rate, 1 msec radio network latency, 10 Mbps/m2 area throughput, and 1 million (low-rate) IoT devices per square kilometer. Key building blocks for 5G are the New Radio (NR) air interface, new radio and core network architectures, virtualization and automation technologies, and new types of devices. These building blocks enable 5G to offer targeted 5G services. Operators worldwide continue to evaluate pre-commercial network trials to ensure a smooth 5G NR network roll-out. The aim is to overcome the challenge of a more demanding and complex air interface and deliver the commercial and technical benefits offered by 5G. While Release 15 eeworldonline.com

The evolutionary path of 5G.

2018 (5G Phase 1) provides a solid framework for enhanced network performance and mass offering of amazing services, 3GPP is actively working on further enhancing the framework.

RELEASE 15 3GPP defined the initial ideas for 5G, called 5G Phase 1, in Release 15 (R15). Example features of R15 include the New Radio (NR) air interface, new radio network architecture called next- generation radio access network (NGRAN), new core network architecture called next generation core (NGC) or 5G core (5GC), service based architecture (SBA), network slicing and edge computing. 6 • 2020

3GPP also defined the next phase of 5G, also called 5G Phase 2, in Release 16. Planned features for Release 16 (R16) include NR unlicensed (NR-U), basically a way for devices to share unlicensed spectra by incorporating some kind of coordination mechanism; integrated access and backhaul (IAB), basically an alternative to fiber backhaul that extends NR to support wireless backhaul; enhanced vehicle-to-everything (eV2X), UltraReliable Low-Latency Communication (URLLC) features that provide low latency and ultra-high reliability for mission critical applications such as industrial internet, smart grids, and remote surgery; and industrial IoT (IIoT) enhancements DESIGN WORLD — EE NETWORK
