DESCRIPTION:Prof. Walid Y. Ali-Ahmad\, Mediatek Inc.\, Singapore\nBio: Wal
 id Y. Ali-Ahmad is currently a Senior Technical Director and RF Lead in th
 e RF division of Mediatek Inc.\; he has been with Mediatek since Oct 2007\
 , and is currently involved in LTE and LTE-Advanced RFIC systems and advan
 ced radio architectures development. His system design work led to the suc
 cessful development of Mediatek’s family of low cost 3G/HSPA+ multi-band
  transceiver chipsets which are currently in mass production for low-cost 
 3G Smart Phones. Prior to Mediatek\, between September’04 and September
 ’07\, he was an associate professor in ECE department at the American Un
 iversity of Beirut\, with teaching focus on applied electromagnetic and RF
  systems and circuits. Between June’97 and September’04\, he was a Pri
 ncipal Member of Technical Staff at Maxim Integrated Products\, Sunnyvale\
 , CA\, in the wireless communications division\, where he led the architec
 ture and system design of the first direct-conversion radios for broadband
  CDMA Wireless Local Loop systems and for WCDMA cellular handsets. His fir
 st job after graduate school was as microwave design engineer at Anritsu c
 ompany developing high-dynamic receivers for ATE systems. He received his 
 Ph.D. in Electrical Engineering from the University of Michigan\, Ann Arbo
 r in December 1993\, and his B. E. in Electrical Engineering with distinct
 ion from the American University of Beirut in June 1988. He is a Senior IE
 EE member and on the steering and TPC committee of the IEEE RFIC conferenc
 e. He has given several invited talks at different IEEE workshops in the a
 rea of cellular transceivers system design and high-frequency radio develo
 pment. Dr. Ali-Ahmad holds two patents in the area of RF design and has mo
 re than 40 publications in conferences\, journals\, and technical magazine
 s.\nThe growing demand for increased data rates and the surging volume of 
 data traffic volumes have been behind the main push for the evolving 3GPP 
 cellular standards\, in order to meet those stringent network demands. To 
 meet those demands\, the user equipment (UE) will need to evolve in the fu
 ture to support the different HSPA configurations required\, such as: Rel-
 8 DC-HSDPA\, Rel-9 extensions of DC-HSDPA operation together with dual-ban
 d or MIMO\, Rel-9 DC-HSUPA\, Rel-10 LTE or 4C-HSDPA with MIMO\, and ultima
 tely\, LTE with carrier aggregation (LTE-A) in Rel-11 and beyond. This pre
 sentation will focus on the architectural and system challenges which futu
 re evolved UE configurations will impose on the multi-mode multi-band cell
 ular transceivers integration goal.
