DESCRIPTION:Cloud Radio Access Network (C-RAN) refers to a novel cellular 
 architecture in which low-cost wireless access points\, known as radio uni
 ts (RUs)\, are centrally managed by a reconfigurable centralized "cloud"\,
  or central\, unit (CU). C-RAN allows operators to reduce the capital and 
 operating expenses needed to deploy and maintain dense heterogeneous netwo
 rks\, as well as to reap statistical multiplexing and spectral efficiency 
 gains. \nThe key bottleneck limiting the performance of C-RAN is set by th
 e capacity and latency constraints of the network of fronthaul links that 
 connect RUs and CU. This talk discusses the corresponding technical challe
 nges faced by C-RAN design and overviews some solutions. These include fro
 nthaul compression\, along with generalizations thereof inspired by networ
 k information theory\, and decentralized local control based on alternativ
 e functional splits.  \n\n*There will be a sandwich lunch available follow
 ing the seminar*.\n\n*BIO*:  Osvaldo Simeone received the M.Sc. degree (wi
 th honors) and the Ph.D. degree in information engineering from Politecnic
 o di Milano\, Milan\, Italy\, in 2001 and 2005\, respectively. He is curre
 ntly with the Center for Wireless Communications and Signal Processing Res
 earch (CWCSPR)\, New Jersey Institute of Technology (NJIT)\, Newark\, wher
 e he is an Associate Professor. His research interests concern wireless co
 mmunications\, information theory and machine learning. Dr. Simeone is a c
 o-recipient of the 2015 IEEE Communication Society Best Tutorial Paper Awa
 rd and of the Best Paper Awards at IEEE SPAWC 2007 and IEEE WRECOM 2007. H
 e currently serves as an Associate Editor for IEEE Transactions on Informa
 tion Theory.
