Technical challenges

To set the foundations of the 5G and beyond mobile data network, we will analyze, design, and optimize the performance of a disruptive new mobile network architecture: the SPOTLIGHT architecture. This architecture aims to break performance limitations of the currently loosely inter-connected, resource-fragmented and isolated in operation mobile network ecosystem, by transforming the existing multi-layered set of attachment points to a flat coalition of massively distributed transceivers utilizing a common pool of energy, radio, computing and storage resources that are optimally handled by a cloud-empowered network core. To further reduce response time and enhance network resilience, all functions necessary for mobile communications will be subject of: i) massive parallelization in cloud platforms at the network core (cloud-empowered network management), and ii) big data analysis on-top of a virtual pool of shared energy, radio, computing and storage resources at the network edge (fog-inspired network optimization). SPOTLIGHT will meet the measurable objectives below :

    - Reduce by 50% the aggregate processing, signaling and communication overhead required for mobile data communications in wide geographical regions, by exploiting the massively distributed set of antennas (located at the numerous attachment points) and shifting network control from the currently loosely-interconnected and isolated in operation attachment points to the network core.
    - Support peak data rates close to 10Gbits/s and cell-edge data rate close to 100Mbits/s for 95% of the terminals, by deploying timely highly-effective solutions to the multi-parametric and resource-constrained RRM optimization problem. Such gains will be attained by pooling the currently under-organized and evidently fragmented multitude of resources at the network edge and orchestrating their effective utilization by the network core that will leverage massive parallelization empowered by cloud computing and big data analysis platforms running on-top of the loosely-coupled nodes.
    - Support radio latency lower than one 1ms, high-speed mobility and near-zero mobility overhead over large service areas, by transforming the dense and vastly overlapping collection of the today’s different-purpose networking clusters to autonomous services areas with high spatial diversity.
