Mr Laurent Noël


System Performance Analyst at Videotron, Canada, Mobile Devices Certification
(formerly Senior System Architect at ST-Ericsson)

Until recently Laurent Noel was a senior system architect at ST-Ericsson, France. He worked on reconfigurable multi-mode, multi-standard, digital RF solutions for LTE, FDD-WCDMA, EGPRS, and TD-SCDMA projects.

Throughout 2007 and 2008 he also actively participated in the definition of the DigRF SM v4 standard within the MIPI alliance. Prior to that he worked at BT Laboratories (Martlesham Heath, UK) where he was involved in 3G testing activities and in research on high speed digital optical systems, including millimetre wave radio systems over fibre.

He received a degree in mathematics and physics from the University of Montpellier II, France, in 1991, and a degree as a microelectronics engineer at the "Institut des Sciences de l'Ingenieur" (ISIM), Montpellier, France, in 1994.
