4G LTE. How to develop and test a radio communication system Lorenzo Galati Giordano, Alessandro Gattini, Andrea Bonfante Azcom Technology DEIB - Building 21 (4th floor) Seminar Room "A. Alario" January 28th, 2014 4.15 pm Abstract: LTE (Long-Term Evolution), marketed as 4G LTE, is a standard for high-speed wireless communication of mobile phones and data terminals. It represents the evolution of the GSM/EDGE and UMTS/HSPA network technologies, being the upcoming major step in mobile radio communications. LTE uses orthogonal frequency division multiplexing (OFDM) for its radio access technology and advanced antenna technologies. Moreover, 4G LTE relies on the idea of heterogeneous networks (HetNet), where mobile network is constituted by small and large cells overlapping each other. Accordingly, the increasing demand for “small” radio base stations (i.e. low cost and low complexity base stations) has provided market opportunities for a great number of telecommunication vendors. Azcom Technology is one of them and, during this seminar, you will have the opportunity to learn the story behind the upcoming 4G Long Term Evolution (LTE) radio cellular system and how to develop and test a real Base Station (BTS), with an insight on hardware and software requirements. A 4G-LTE live DEMO session will conclude the seminar. Speakers bio: Lorenzo Galati Giordano received his PhD in Wireless Communications from Politecnico di Milano in 2008. During his PhD he has been a visiting Marie-Curie student at Centre for Wireless Network Design, University of Bedforshire (UK), supported by the European project RanPlan-HEC EU-FP6. In 2009 he has worked as a temporary researcher for the Italian National Research Council (IEIIT-CNR). Since 2010, he has moved to industry working as a consultant for Nokia Siemens Network (Germany) and as a 4G R&D Engineer for Azcom Technology (Italy). Lorenzo’s main areas of interest are: 4G Architectures, Cross Layer Scheduling, Self-Organizing Networks, Vehicular and Mobile Networks, Small Cells deployment, PHY receiver design.

Alessandro Gattini received his degree in Telecommunication Engineering in April 2006 at Politecnico di Milano. Since that year works for AzCom Technology in test and integration field for telecommunication systems. His first area of interest has been WCDMA technology, working mainly in UMTS nodeB-UserEquipment devices integration for testing and commercial purposes both with laboratory experience and on-site support at customer (NSN Japan and China). Currently is involved in a new project of LTE small cell, taking care of integration of the full SW protocol stack (L1-L3) together with the HW (BaseBand and RF). Andrea Bonfante obtained his M.S. degree in Telecommunication Engineering from Politecnico di Milano in 2012. Currently he is working in the LTE Small Cell project at Azcom Technology, focusing on Physical Layer receiver design. He previously held internship position at Azcom Technology during which he implemented the M.S. Thesis on Equalization methods for the LTE uplink.
