We are currently experiencing an explosion of wireless and mobile traffic and in particular mobile data traffic. This exponential growth in traffic is driven by a plethora of new devices (e.g. iPhone, smart phones and tablets) and new applications (e.g. YouTube, Facebook, social networking, machine to machine communication, video conferencing and immersive communication). In particular mobile video is one of the main drivers behind the current and predicted traffic growth leading to a factor 30 increase over the next ten years. In addition, consumers and businesses have ever-increasing demands for anywhere and anytime connectivity with a high quality broadband experience and seamless mobility across diverse devices. In this presentation, Dr. Klein will review these high-level trends in wireless communication networks and discuss some of the current and future challenges from both technical and business perspectives to meet this increasing demand for wireless services. He will present several paradigm shifts that are currently being investigated. For example, innovative wireless network architectures include small cells as an overlay to traditional macro cells as well as heterogeneous and multi-technology networks. Self-organization and intelligent management of these networks are required to handle network complexity, user and traffic dynamics and ultimately guarantee end-user quality of service in a cost-efficient manner. During the talk, Dr. Klein will also share lessons learned and some personal experiences from research and entrepreneurship in an industrial lab such as Bell Labs.

Thierry Klein Ph.D.

Bell Laboratories/Alcatel-Lucent


Thierry Klein joined Bell Labs Research in 2001 conducting fundamental and applied research on next-generation wireless and wireline networks, network architectures, algorithms and protocols, network management, optimization and control. In 2007, Thierry founded a start-up company focused on wireless communications for emergency response situations within Alcatel-Lucent Ventures. Thierry served as the CTO of the Venture until his return to Bell Labs Research in February 2010, where he is now the Director of the End to End Wireless Networking Research Department in the Networks and Networking Research Domain in Murray Hill, NJ. He earned an MS in Mechanical Engineering and an MS in Electrical Engineering from the Universite de Nantes and the Ecole Centrale de Nantes in Nantes, France. Thierry received a PhD in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology, USA. He is currently leading a Bell Labs wide team across several departments and locations on energy efficient routing, switching and networking with the goal of dramatically increasing the energy efficiency of communication networks. Since June 2010, he also serves as the Chairman of the Core Switching and Routing Working Group within Green Touch, a global consortium dedicated to improving energy efficiency in networks by a factor 1000. He is an author on over 35 peer-reviewed conference and journal publications and an inventor on 36 patent applications. He is a member of the Alcatel-Lucent Technical Academy and the recipient of a Bell Labs’ President Award and two Bell Labs Teamwork Awards. In 2010, he was voted “Technologist of the Year” at the Total Telecom World Vendor Awards.
