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.

4 zettaoctets de données générées en 2013, 44 à l’horizon 2020 et 185 en 2025. Ces chiffres donnent le vertige. Ils illustrent parfaitement cette nouvelle ère du déluge de données, devenues un enjeu économique et sociétal majeur et dont le traitement se fait à la vitesse du maillon le plus faible dans un système informatique : le système de stockage. Il est donc crucial d’optimiser le…

Sub-sampling of channels with time and frequency sparsity access
This paper shows that sub-sampling of signals can help in reducing the amount of data to be processed and stored when time and frequency sparsity is considered. The context is the one of the Internet of Things (IoT) for which a huge quantity of users (i.e. objects) communicate with very few time and frequency accesses. Taking advantage of the occupancy theory of probabilities, we propose a…

Firewall Policies Provisioning Through SDN in the Cloud
The evolution of the digital world drives cloud computing to be a key infrastructure for data and services. This breakthrough is transforming Software Defined Networking into the cloud infrastructure backbone because of its advantages such as programmability, abstraction and flexibility. As a result, many cloud providers select SDN as a cloud network service and offer it to their customers…
