T H E M E: 5G: T H E N E X T G E N E R AT ION The Path to 5G: Challenges, Benefits and Endless Possibilities By Femi Adeyemi, Ph.D. Lead Architect, LTE Solutions, Fujitsu Network Communications, Inc. T he rise of the Internet of Things (IoT) is propelling the mobile Radio Access Network (RAN) toward another major technology shift. The demands of Machine to Machine (M2M) and Device to Device (D2D) communication have caused a fresh influx of data-intensive, highavailability, low-power applications, all optimized by 5G. An Atypical Inflection Point Technology transition cycles in mobile networks generally occur every seven to ten years, as exemplified by the 2G, 3G and 4G transitions. But the upcoming 5G inflection is not following this norm. Some mobile network operators (MNOs) have yet to reach a point where they provide complete support for additional LTE Advanced features, such as enhanced interference management, coordinated multipoint connectivity, and carrier aggregation. In addition, many MNOs have either not fully monetized their current 4G networks or have yet to fully migrate from 3G to 4G; these operators have work to do before they can see the value and benefits of moving to 5G. This is both an exciting and uncertain time. The next-generation architecture promises lower latency, higher data rates-and support for interesting and innovative mobile applications. Unfortunately, the 5G standards that will guide the wireless industry through uniform technology implementation and deployment are yet to be completed. Therefore, in order to avoid repeating the complicated history of network transitions like the move from 3G to 4G, MNOs are evaluating transition options that can leverage their existing 4G deployment while preparing for fully standardized 5G technology implementation. The industry has heeded the lessons learned from the operators who rushed to be first to offer 4G high-speed wireless services, with the consequent premature introduction of "3.5G network" deployments and labeling of HSPA as 4G technology. Considering the Transition Options One such RAN network transition option is migration from the 4G distributed RAN architecture (DRAN) to a centralized RAN architecture (CRAN). This involves aggregation of a number of RAN basebands into a centralized location or "BBU hotel," while leaving the remote radio heads at the remote location. This CRAN architecture also introduces new concepts such as fronthaul, and offers the potential to reduce network capex and opex. The other potential transition path focuses on specific 5G use cases, such as fixedwireless broadband, that can be Figure 1: Overlaying the 4G Network with 5G Technology THE VOICE * www.ccamobile.org * Fall/Winter 2016 35 http://www.ccamobile.org
