5G promises more throughput, lower latency, and better power consumption than prior “Gs” to support a broader constellation of services and use cases beyond voice and IP data. Our aim is to present often-overlooked elements of the 5G toolchain that support the vision. We begin by highlighting the aspects where 5G NR is an improvement over 4G LTE and conclude that it is in the systems-level aspects where the 5G system and specifically, 5G New Radio, is superior to prior “Gs”. To make the case stronger, we then highlight problem statements and their solutions in macro networks, edge computing, and in private 5G where the essence of the solution is the superior spectrum management employed by the 5G system. Using the 5G New Radio waveform alone without the context for the use case will not achieve any desired business outcome. Instead, the wireless industry needs the flexibility afforded by the system toolchain as applied to a specific use case domain.
The 5G Systems as a Spectrum Management Solution
Humberto J. La Roche is Principal Engineer in Cisco’s Mass-scale Infrastructure Group where he is responsible for 5G solution architecture. In his career spanning over twenty-five-year in telecom, he has been responsible for LTE systems engineering, product management of IMS and wireless softswitch products, product planning of optical networking and broadband access products, and transport network design. He is listed as author in over eleven technical papers and as inventor on over twenty patents. Humberto holds a PhD degree in Physics from the University of Texas at Austin.
