Query: The CTTC 5G end-to-end experimental platform: Integrating heterogeneous
  wireless/optical networks, distributed cloud, and IoT devices   The Internet of Things (IoT) will facilitate a wide variety of applications
in different domains, such as smart cities, smart grids, industrial automation
(Industry 4.0), smart driving, assistance of the elderly, and home automation.
Billions of heterogeneous smart devices with different application requirements
will be connected to the networks and will generate huge aggregated volumes of
data that will be processed in distributed cloud infrastructures. On the other
hand, there is also a general trend to deploy functions as software (SW)
instances in cloud infrastructures [e.g., network function virtualization (NFV)
or mobile edge computing (MEC)]. Thus, the next generation of mobile networks,
the fifth-generation (5G), will need not only to develop new radio interfaces
or waveforms to cope with the expected traffic growth but also to integrate
heterogeneous networks from end to end (E2E) with distributed cloud resources
to deliver E2E IoT and mobile services. This article presents the E2E 5G
platform that is being developed by the Centre Tecnol\`ogic de
Telecomunicacions de Catalunya (CTTC), the first known platform capable of
reproducing such an ambitious scenario.
