Workshop II: Optical technologies in the 5G Era
Research and Standardization on 5G topics has been ongoing for the last years, aiming at defining the next generation of data networks, addressing well-known use cases such as enhanced mobile broadband (eMBB), ultra-low latency reliable communications (URLLC) and massive machine type communications (mMTC), with requirements including over 10 Gpbs peak rates, 1M /Km2 and < 1 ms latency. The 5G initiative is being supported by multiple standardization bodies, such as the 3GPP and the ITU-T coming together to define new standards, while the European 5G Infrastructure Public Private Partnership (5G PPP) and similar initiatives worldwide are funding a large part of the ongoing 5G research.
However, besides new services and applications, 5G will also need to support a wide range of vetical business ecosystems and cooperation models enabling business horizontalization. 5G goes far beyond the definition of new radio access technologies and radio interfaces and is about a new end-to-end network vision, in which softwarization and virtualization allow a common network infrastructure to be flexibly used for a variety of diverse applications. In this context, optical technology can play a key role supporting end-to-end requirements involving a 1000-fold increase in capacity and connectivity, with stringent requirements in terms of bandwidth, and latency control.
This workshop aims at discussing the role of the optical technology in building 5G networks from different perspectives, addressing aspects such as:
- What is the role of optical technologies (transmission and switching) in 5G networks, especially in view of key challenges such as density of access points, energy savings, bandwidth, latency or reliability requirements? Are new architectures required? How important is research in access, metro and core optical networks in 5G?
- How will network softwarization affect optical transport networks and how can 5G networks benefit from the optical layer programmability?
- What are the opportunities for optical and wireless integration? What are the benefits (and challenges) of converged fronthaul and backhaul? How can fronthaul benefit from the recent advances in optical technologies? Is optical the only technology available for packetized front-haul?
