DEVAKI CHANDRAMOULI has over 18 years of experience in the telecommunication industry. She spent the early part of her career with Nortel Networks and is currently with Nokia. At Nortel, her focus was on the design and development of embedded software solutions for CDMA networks. Later, she represented Nortel on the Worldwide Interoperability for Microwave Access (WiMAX) Forum with a focus on WiMAX architecture and protocol development. At Nokia, her focus areas include architecture and protocol development of 5G System and EPS related topics. She has been instrumental in developing Nokia's vision for 5G System Architecture and she has also been instrumental in developing Nokia's strategy for radio and architecture standardization (phased) approach in the 3rd Generation Partnership Project (3GPP). She leads 5G System Architecture specification in 3GPP SA2 and continues to focus on active contribution toward evolution of 5G System work in SA2. She is now Head of North American Standardization in Nokia. She has co‐authored IEEE papers on 5G, co‐authored a book on “LTE for Public Safety” published by Wiley in 2015. She has (co‐)authored over 100 patents in wireless communications. Devaki received her B.E. in Computer Science from Madras University (India) and M.S. in Computer Science from University of Texas at Arlington (USA).

RAINER LIEBHART has 25 years of experience in the telecommunication industry. He held several positions within the former Siemens Fixed and Mobile Networks divisions and now in Nokia Mobile Networks. He started his career as SW Engineer, worked later as standardization expert in 3GPP and the European Telecommunications Standards Institute (ETSI) in the area of Internet Protocol Multimedia Subsystem (IMS), took over responsibilities as WiMAX and Mobile Packet Core System Architect and was head of the Mobile Core Network standardization team in Nokia Networks for more than eight years. He was also the Nokia Networks main delegate in 3GPP SA2 with the focus on Long‐Term Evolution/System Architecture Evolution (LTE/SAE). After working as Research Project Manager within Nokia Bell Labs with a focus on 5G, he is now Head of 5G Solution Architecture in the Mobile Networks Global Product Sales department of Nokia. He is (co‐)author of over 70 patents in the telecommunication area and co‐editor of the book “LTE for Public Safety” published at Wiley. Rainer Liebhart holds an M.S. in Mathematics from the Ludwig‐Maximilians University in Munich, Germany.

JUHO PIRSKANEN has 18 years of experience on technology development on wireless radio technologies such as 3G, HSPA, LTE and WLAN and most recently on 5G. He has held several positions in Nokia Networks, Nokia Wireless Modem, Renesas Mobile Corporation and Broadcom Corporation and then again at Nokia Networks for 5G research and standardization. He has participated actively for several years on different standardization forums such as 3GPP and IEEE802.11 by doing numerous technical presentations, being rapporteur of technical specifications and leading different delegations. His research work has resulted in more than 40 (co‐)authored patent families on different wireless technologies and several publications on radio interface solutions including 5G. On 5G his research focused on physical layer and radio protocol layer concepts and first implementations of the 5G radio solutions. In late 2017, he joined Wirepas having headquarters in Tampere, Finland. Wirepas develops de‐centralized wireless IoT mesh networks that can be used to connect, locate and identify lights, sensors, beacons, assets, machines and meters with unprecedented scale, density, flexibility and reliability. Juho Pirskanen holds a Master of Science in Engineering, from Tampere University of Technology, Finland.
