Integrated RAN to meet the QoS of modern wireless application

Abstract

The forthcoming wireless world is expected to have a variety of applications including massive IoT devices, vehicular communication, high-quality gaming, etc. Due to distinct Quality of Service (QoS) requirements, these applications demand different size of band-width and often possess significant variations in the working. Therefore, it is challenging for the existing cellular infrastructures to support such wide range of applications. On the other hand, there are some wireless technologies that are still underutilized, e.g., Narrow-Band Internet of Things (NB-IoT). To fill this gap, we propose a an integrated Cloud Radio Access Network (CRAN) architecture. Specifically, this work integrates the existing CRAN architecture with the NB-IoT. CRAN supports Coordinated Multi-Point (CoMP) transmission. So, the proposed integrated scheme intends to utilize full potential of microwave and mm-wave. Moreover, simulation results show that our proposed architecture suitably provides a better quality of Service (QoS) to all respective users.
