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.
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.

A Cloud RAN Architecture for LoRa
This paper deals with a cloud radio access network (CRAN) architecture for the LoRa system. In the suggested design, the gateway embeds a limited remote radio head (RRH), including the analog radio-frequency (RF) analog part, the digital-to-analog and analog-to-digital conversion, and a digital front-end (DFE). The other LoRa network functions, including the physical (PHY) layer, the LoRaWAN…

Flexible Multi-standard Digital Front-End for LPWA Technologies
This paper proposes a flexible multi-standard digital front-end (DFE) hardware architecture designed for three main low-power wide-area (LPWA) technologies: LoRa, Sigfox, and narrowband-Internet of things (NB-IoT). We demonstrate the feasibility of an unified DFE architecture that fits the requirements of these LPWA technologies. The proposed DFE architecture has been implemented on a Spartan-6…

Les réseaux SDN et NFV : un nouvel élan et une nouvelle opportunité pour la tomographie en réseaux
The network slicing concept promises significant flexibility and autonomy for network management. Thanks to its main key features, heavily relying on the NFV and the SDN technologies, new communication services can be designed and deployed much faster than before. However, maintaining the necessary reliability level of conventional networks remains a major open problem. One of its consequences is…
