Panel I: Reality Check for 5G Networks: Network Operator Perspective

Wednesday, 09 June 11:00 – 12:30

Moderator: Mehran Esfandiari, NTE Consulting, USA

Panel Description:

5G promises to revolutionize society and industry by enabling service provider & network operators to provide a wide range of services, such as enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (uRLLC) and massive Machine-Type Communications (mMTC). This diverse set of services place different requirements on the transport network, including x-haul optical architectures, RAN, Edge Computing (MEC), latency & reliability.  This Network Operator Summit session will assemble speakers from leading edge operators around the world to share the current state of affairs and offering a reality check on operating 5G networks.

Key questions to be addressed are: 

  • What is the current status and challenges of 5G architectures from real-world deployments, experiments, prototypes, and testbeds? What are the time frames for implementation?
  • How would 5G network slicing be implemented? By 5G application type (eMBB, uRLLC, mMTC)? By virtual or physically separated connections or networks? By control plane and orchestration entities only?
  • What are the requirements on latency and reliability with different service types, what are the most stringent ones? How do these impact the RAN x-haul access/metro/core architecture?
  • How does Edge Computing and Disaggregated Cell Site Gateway, CU/DU impact the traditional separation between mobile, access, and metro/aggregation networks?
  • What are the tradeoff and benefits of distributed-RAN vs. centralized-RAN vs. cloud-RAN on x-haul networks? What can edge cloud do to address latency issue and are these scalable solutions?
  • In which part of x-haul would CWDM & DWDM features such as dynamic reconfiguration, super-channels, spectrum routing, and subcarrier aggregation be beneficial?
  • What are the most promising architectures for coherent optics or mini-ROADMs in the 5G access? At which level could a mini-ROADM expand to mid-haul and back-haul networks?
  • Where are the best fit and application for OTN and/or Ethernet aggregation in mid & back-haul transport networks? How does FlexO and Flex-E weigh in?
  • For operators with fixed broadband networks, how can those networks be optimally leveraged for cost-effective 5G transport?

Philippe Chanclou, Orange Labs, France
Presentation Title: 5G Ready Fibre to the Antenna
Abstract: Today's challenges of 5G deployment in Orange's network will be addressed. A view of how/when optical fibre serves Radio Access Network (RAN) backhaul, midhaul and fronthaul, will be addressed especially with the coming open-source supplier ecosystem based on O-RAN initiative. A focus on short reach transceivers and optical access networks will be proposed to achieve Fibre-to-The-Antenna (FTTA).

Philippe Chanclou joined the R&D facilities of France Telecom in 1996 where he worked on the research of active and passive optical telecommunications functions for access networks. In 2000, he joined the IMT Atlantique as a senior lecturer where he was engaged in research on optical switching and optical devices using liquid crystal for telecommunications. During 2001 to 2003, he has participated to the foundation of Optogone Company. Since 2004, he joined Orange Labs where he was engaged in research on the next generation optical access networks. He is now manager of Fixed Access Networks team . This team is an active about FTTx topics for Home (Passive Optical Network), Enterprise (Passive Optical LAN) and Antenna (including the transport of radio access network interfaces “xhaul”).

Andrew Lord, BT, UK
Presentation Title: Data and Control Plane Technologies that Will Enable Future 5G Applications
Abstract: 5G is a catalyst for optical network growth in the metro. There are a variety of solutions including direct detection or coherent modulation and those with optical switching or filterless. There is also the choice between point-point and point-multi-point. Additionally, cost is as important as flexibility. This talk will review the main candidates, pin-pointing pros and cons, and BT's current status and thinking.

Andrew heads BT’s optical core, access and quantum research. He was Chair of the Optical Fiber Communications Conference 2017 in Los Angeles. He is Visiting Professor at Essex University. He won the prestigious BT Martlesham Medal in 2018. He recently led the 5G Metro-Haul EU-funded project.


Kosuke Nishimura, KDDI Research, Japan
Presentation Title: Mobile Fronthaul for Accommodating Enormous Data Traffic in Final Phase of 5G and Beyond
Abstract: 5G will provide capacity of 20 Gbit/s as maximum users' throughput for downlink in its final phase, and further capacity expansion is expected for Beyond-5G.  Our recent achievements of research and development is presented regarding mobile fronthaul transmission based on analog Radio-over-Fiber scheme, which has potential sustainability from 5G toward Beyond-5G.

Kosuke Nishimura is a senior expert in KDDI Research, Inc.  He is currently working on research and development of transmission technology and network architecture for mobile fronthaul in 5G and B5G mobile system.
