Advanced Connectivity
Communication systems are experiencing a major change being driven by their convergence on technologies drawn from information systems: Network programming, virtualization, and now cloudification, flexibility, and speed of deployment.
To become proficient in high-quality end-to-end services, meet the needs of various industries, and offer a better user experience, it is necessary to find solutions for broadband mobile and IoT that are coordinated with access networks and core networks alike.
The Advanced Connectivity lab is helping this change come about by designing software and hardware solutions ranging from radio access (massive MIMO, millimeter waves, new FECs) to core network infrastructure (SDN architecture, CUPS, and micro-services) that can address these new needs. The lab relies on expanded areas of skill such as radio, signal processing, systems on-chip (SoC), Software-Defined Radio (SDR) platforms, software development, and cloud infrastructure. It handles these subjects by offering architecture upgrades that restructure the functions toward the Edge network.
Drawing on the findings of many mobile network research projects over the past 5 years, we have the ingredients to accelerate development for the xG plan and 5G sovereignty.

Energy Efficiency of Hybrid Unicast-Broadcast Networks for Mobile TV Services
The increasing popularity of linear services such as mobile TV, broadcasting live and sports events using mobile and portable devices, has led to a dramatic growth of the mobile data traffic. To deal with this traffic explosion, future networks have to increase the capacity offered to mobile communications, while at the same time trying to reduce their energy consumption. Actually, recent studies…

On Evaluating Different Trends for Virtualized and SDN-ready Mobile Network
Software Defined Networking (SDN) is one of the key enablers for evolving mobile network architecture towards 5G. SDN involves the separation of control and data plane functions, which leads in the context of 5G, to consider the separation of the control and data plane functions of the different gateways of the Evolved Packet Core (EPC), namely Serving and Packet data Gateways (S and P-GW)…

Power-Aware Regeneration Algorithm in Flex-grid Networks
Flex-grid technology increases network links capacity and optical power levels, creating power saturation problem in legacy amplifiers. We demonstrate that optimizing regeneration sites allows reducing the optical power of highly loaded links, avoiding amplifiers saturation over the existing fixed-grid networks.
