Introduction
I am a group manager at I2CAT in Barcelona. Previously I worked at NEC Network Laboratories in Germnay. My main research interests comprise wireless networks, QoS, energy efficiency, algorithms, but I am basically passionate about anything related to networking. I am also involved in standardization for wireless LANs and have contributed both to the Wi-Fi Alliance and to the IEEE 802.11 working group.

5GCity’s main aim is to build and deploy a common, multi-tenant, open platform that extends the (centralized) cloud model to the extreme edge of the network, with a demonstration in three different cities (Barcelona, Bristol and Lucca).
Project
http://www.5g-xhaul-project.eu 5G-XHaul aims at building up an ambitious converged optical and wireless network solution that relies on a flexible infrastructure able to support of the backhaul and fronthaul networks required to tackle the future challenges that RAN imposes. 5G-XHaul will provide an efficient, reconfigurable, modular and highly scalable platform to support RAN processing, depending on different architectural solutions, network elements and devices. The future 5G backhaul requires higher flexibility to unlock the potential of increased, more efficient and more flexible spectrum usage. The high deployment cost of optical fibre will be alleviated in 5G-XHaul with the use of mm-Wave communications for both backhaul and fronthaul purposes.
