Trends in Evolution of Mobile Wireless Infrastructure, An Industry Perspective

Dr. Habib Riazi and Dr. Aravind Chamart, Corning Optical Communications Wireless Inc.
Dr. Durga Satapathy, Director of Technology Innovation & Architecture, Sprint
There has been ample research and focused academic work, suggesting improvements and guiding new technologies, for mobile wireless radio access and architecture. The purpose of this tutorial is to provide a broad perspective on the drivers and latest trends affecting changes and continued modernization of commercial mobile wireless infrastructure. We will review the shortcomings with respect to the growing data traffic, inefficiencies in spectrum utilization, capital expenditure and operating cost concerns. Then review enabling developments in the areas of spectrum repurpose and promising economic efficiencies of developing technologies such as; SDR, NFV, C-RAN, and 4G progression to 5G. We take a look at challenges in physical implementation and the facilitating engineering innovations. The purpose of this tutorial is to provide a broad insight and perspective on the system evolution. In the course of discussions, we will also identify relevant references and major influencers for further investigation into specific areas of interest.
Tutorial Outline:
This tutorial will try to present the importance of current and ongoing trends in mobile wireless industry and its professional, technical, and business impact. This tutorial will be delivered in three sessions of one hour each.
  • In the first session, Habib will give a high-level overview of today’s complex global wired and wireless networks that is supporting human connectivity and applications thereof. He will discuss the impending evolution of adding things to this web of connectivity and resulting convergence of our digital and physical world. Will highlight the pace setting global harmonization which has contributed to the economy of scale and phased but rapid technological development. Will discuss the need to transition to a new air interface in the next generation of wireless standard and briefly discuss the technical reasons supporting these changes as compared with the current state of the art. Habib’s presentation sets the stage for more detailed insight provided in the next two sessions of this tutorial.

  • In the second session, Aravind will discuss the role of user equipment (UE) location technologies and sensors in context generation for IoT. He reviews the Internet of Things ((IoT), big data, artificial intelligence (AI), and context. He explains importance of UE in context generation. Then illustrates relation of location and context and describes various UE location technologies; including UE-based, network-based, and AGPS-based. He will highlight the impact of smartness and privacy and importance of security.

  • In the third and final part, Durga will discuss trends in mobile wireless radio access and architecture from a tier one and major service provider’s vantage point — including some that are new and others that are known but becoming more relevant and practical. He will broadly address areas of evolution in radio access networks, backhaul, core, and devices. In particular, trends that contribute to spectral efficiency enhancement, coverage extension, capacity growth, deployment ease, etc. will be highlighted. These include Massive MIMO, Full Duplex, Spectrum Approach (Carrier Aggregation, Unlicensed Bands, Millimeter Wave Bands etc.), Densification with Small Cells, Virtualization, IOT, V2X, 4G to 5G Evolution etc. He illustrates some challenges in implementing these solutions and provide an operator’s perspective in leveraging such solutions for systems evolution.
