Panel II: Optical Mobile Network Access

Wednesday, 22 March
13:30 - 15:00
Theater I

Željko Bulut, Product Line Manager, Coriant, USA

Panel Description:

Fixed-Mobile convergence (FMC) has been touted for years as saving capex, opex and simplifying network management. Concurrently, IoT is regarded as a major stimulus for 5G, creating demand for small cells throughout indoor and outdoor urban areas.
Fiber-based metro and access solutions are positioning themselves to support the massive amount of data to be backhauled as IoT ramps.
Will FMC finally happen? Will the two worlds find a common language?
Some of the questions addressed in this panel will include:

  1. Will IoT drive Optical Mobile Network Access?

  2. What are service providers seeking in terms of solutions?

  3. Who are the ecosystem vendors? Who will benefit and why?

  4. Are standards needed?

  5. How do mobile backhaul and fronthaul need to change to support applications like IoT?
