Panel 2: 5G Applications and Networks: Real-world Operator Case Studies

Wednesday, 06 March
13:30 - 15:00
Expo Theater I

Moderator: Sterling Perrin, Industry Analyst, Heavy Reading, USA

Panel Description:

There is tremendous hype surrounding 5G currently, but away from the hype there is also real 5G-activity and operator progress taking place. For example, AT&T has announced ambitious plans to roll out mobile 5G in multiple cities across the United States in 2018, while Verizon has outlined its own commercial plans for 5G fixed wireless access (FWA). In Asia, early 5G capabilities were demonstrated at the 2018 Winter Olympics in South Korea, and Intel and NTT Docomo have announced plans to turn Tokyo into a smart city for the 2020 Summer Olympics. These are just a few examples. Small-scale trials and isolated deployments don’t require much change to the supporting wireline infrastructure, but wide scale commercial adoption mandates significant planning and possibly a re-think of the entire network as operators seek to support extreme mobile broadband, ultra-low latency, and massive machine-type application requirements.

This Network Operator Summit session will assemble speakers from leading edge operators around the world that are trialing and commercializing the first 5G applications and services regions to share their plans, perspectives, and lessons learned so far. Perspectives will include both mobile 5G as well as 5G fixed wireless access (FWA) services. Throughout the session, speakers will tie their plans and requirements to their optical networks and roadmaps, including fronthaul, mid-haul, backhaul and the metro core. The key questions throughout will be: how must optical networks adapt and change to meet the capacity and performance requirements of 5G?
