6.3.2 CTTC 5G End-to-End experimental Platform

The fifth generation of mobile networks technology (5G) is not only about the development of new radio
interfaces or waveforms. It also deals with the design of end-to-end converged network and cloud
infrastructure to facilitate both traditional human-based and emerging Internet of Things (IoT) services. This
converged infrastructure, illustrated in Fig. 1, is composed of: i) end-to-end heterogeneous network
segments covering radio and fixed access, metro aggregation, and core transport with heterogeneous
wireless and optical technologies; ii) massive distributed cloud computing and storage infrastructures; and
iii) large amounts of heterogeneous smart devices and terminals for traditional mobile broadband services
(e.g., smartphones, tablets, etc.) and IoT services (e.g., sensors, actuators, robots, cars, drones, etc.).
Conducting real-life demonstrations of such a complex system is not easy. CTTC is working in the
development of the first-known 5G end-to-end experimental platform for testing advanced end-to-end IoT
and mobile services. The approach consists in integrating various existing experimental facilities already
available at CTTC which cover activities from the PHY layer to the application/service layer for mobile
networks. The building blocks of this demonstration platform are shown in Fig.2. These facilities cover
complementary technologies ranging from terminals, sensors and machines, to radio access networks,
aggregation/core networks, and cloud/fog computing. Specifically, the five existing experimental facilities
involved are: i) the ADRENALINE Testbed® for wired fronthaul/backhaul (SDN-enabled packet aggregation
and optical core network, distributed cloud and NFV services in core and metro data-centers); ii) the
EXTREME Testbed® and LENA LTE-EPC protocol stack emulator for wireless fronthaul/backhaul and mobile
core and RAN (SDN-enabled wireless HetNet and backhaul, edge data center and distributed computing
nodes for cloud and NFV services); iii) the GEDOMIS® testbed for LTE/5G PHY real-time prototyping based on
FPGAs and software-defined radio (SDR), and the CASTLE testbed (a highly configurable software tool
allowing LTE/5G/Satellite PHY layer development and testing); iv) an LTE/5G analog front-end µwave &
mmwave (antenna, power amplifier, filter, mixer, etc.,) including digital pre-distortion (SHAPER), and energy
harvesting devices for the IoT; and v) the IoTWorld Testbed integrating sensors, actuators, and wireless/wired
gateways.
