Balazs Bertenyi, Chairman of 3GPP TSG-RAN, Hungary

Balazs Bertenyi received an M.Sc. Degree in Computer Science and Telecommunications in 1998 at the Technical University of Budapest.

Balazs joined Nokia in 1998 and started to work on circuit switched mobile switching.

In 1999 he joined the research group on IMS (IP Multimedia Subsystem) and soon started to work in 3GPP standardization on IMS architecture.

  • 2000–2003 Representative of Nokia in 3GPP SA2 (Architecture Working Group)
  • 2003–2007 Head of delegation for Nokia in 3GPP SA2
  • 2007–2011 Chairman of 3GPP SA2
  • 2011–2015 Chairman of 3GPP TSG-SA (Technical Specification Group – Services and System Aspects)

In 2015 Balazs moved to the radio standardization group within Nokia to focus on 5G matters. He started attending TSG-RAN in 3GPP in 2015 covering 5G topics.

In 2017 Balazs was elected as Chairman of TSG-RAN for a 2-year term with a potential to be re-elected for one additional term.

Balazs has led various key projects for Nokia on Mobile Broadband architecture and standards strategy.

Satoshi Nagata, Vice Chairman of 3GPP TSG-RAN , Japan

Satoshi Nagata received his B.E. and M.E. degrees from Tokyo Institute of Technology, Tokyo, Japan, in 2001 and 2003, respectively. In 2003, he joined NTT DOCOMO, INC. He worked for the research and development for wireless access technologies for LTE, LTE-Advanced. He is currently a senior research engineer working for 5G and 3GPP standardization. He had contributed to 3GPP over 10 years, and contributed 3GPP TSG-RAN WG1 as a vice chairman during November 2011 to August 2013, and also contributed as a chairman during August 2013 to August 2017. He is currently a vice chairman of 3GPP TSG-RAN since March 2017.

Havish Kooropaty, Vice Chairman of 3GPP RAN1, Master Researcher at Ericsson Inc., San Francisco, USA

Havish Koorapaty (Havish.Koorapaty@ericsson.com) received his B.S., M.S., and Ph.D. degrees in Electrical and Computer Engineering from North Carolina State University in 1991, 1993 and 1996 respectively. He has been with Ericsson Research since 1996, where he has worked in the general area of wireless communications systems including cellular and satellite systems. His work spans a wide range of topics including error control coding, location determination and tracking, mobile phone systems engineering, 4G broadband wireless system design, wireless backhaul solutions, energy efficiency, spectrum sharing and small cells. He has over 200 technical papers and patents in these areas. He has represented Ericsson in standardization efforts in the TIA, IEEE and ETSI standardization bodies. Recently, he has worked on LTE evolution and 5G wireless systems. He has been involved in standardization efforts in 3GPP for 5G NR and LTE including serving as the rapporteur for the licensed-assisted access study and work items. He is currently serving as a vice-chairman in 3GPP RAN1.

Xutao Zhou, Chairman of 3GPP RAN4, Engineer at Samsung R&D Center, Beijing, China

Xutao Zhou received his Master Degree in Telecommunications form University of Warwick, UK. Mr. Zhou has been employed with Samsung Research China Beijing in 2007 and has been working in standard team, focusing on standardization of mobile communications. Mr. Zhou has been elected as 3GPP RAN4 Chairman in 2015. Since then, Mr. Zhou has been chairing the 3GPP RAN4 meetings for defining the radio frequency requirements for 5G NR and LTE.

Wanshi Chen, Chairman of 3GPP RAN1, System Engineer at Ericsson, Greater San Diego, USA

Wanshi Chen is currently 3GPP TSG RAN1 Chairman, where under this position, he has successfully managed a wide range of 3GPP TRG RAN1 Long Term Evolution (LTE) and New Radio (NR) sessions. He has over 18 years of experiences in telecommunications in leading telecom companies including operators, infrastructure vendors, and chipset vendors. He has been with Qualcomm since 2006 and is responsible for LTE and NR research, design, and standardization. From 2000 to 2006, he was with Ericsson for 3GPP2 related system design, integration, and standardization. He also worked for China Mobile between 1996 and 1997 for wireless network maintenance and optimization. He received a Ph.D. degree in electrical engineering from the University of Southern California, Los Angeles, CA, USA.
