Author Biographies

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.

Richard Burbidge, Chairman of 3GPP RAN2, Senior Wireless Systems Architect at Intel Corporation, Shrivenham, Oxfordshire, UK

Richard Burbidge is a Senior Principal Engineer with Intel Corporation. With 25 years of experience in the wireless industry, he has been involved with the development of cellular standards since 1998, and has been a 3GPP delegate since its inception in 1999. Over this time he has contributed to 3 generations of cellular technology, firstly UMTS, then LTE, and now NR, 3GPP’s 5G technology. He is currently serving as the chairman of the 3GPP TSG RAN 2 committee that is responsible for the specification of the layer 2 and 3 radio interface protocols for LTE and 5G/NR, having previously served as the vice chairman from 2005–2009. Richard received a Bachelor’s degree in Electrical and Information Sciences from the University of Cambridge in 1993.

Gino Masini, Chairman of 3GPP RAN3, Systems Manager - Concepts and Standards at LM Ericsson AB, Stockholm, Sweden

Gino Masini, MBA received his M.Sc. degree in Electronics Engineering from Politecnico di Milano and his MBA from SDA Bocconi School of Management in Milano, Italy. He started his career as a researcher in the Department of Electronics at Politecnico di Milano, working on microwave propagation and satellite telecommunications for the European Space Agency and the Italian Space Agency. He joined Ericsson in 1999, working at first on microwave antennas and network planning for microwave radio links, and later with MMIC design. Since 2009 he works with 4G and 5G radio network architecture, interfaces, and protocols. He is active in standardization since 2001: he attended ETSI, ITU, CEPT, and occasionally the Small Cell Forum. He is active in 3GPP since 2009, and he is currently serving as 3GPP RAN WG3 Chairman. He has more than 30 patents granted, he authored or co-authored more than a dozen scientific publications, and he holds a “Six Sigma” certification.

Sasha Sirotkin, Vice Chairman of 3GPP RAN3, Senior wireless architect at Intel Corporation, Israel

Sasha Sirotkin is a senior wireless architect in the Next Generation and Standards group at Intel Corporation. Sasha has over 15 years of experience in wireless communications, in product development, system architecture, standardization and research. Sasha is currently serving as the vice chairman of 3GPP TSG RAN 3 committee that is responsible Radio Access Network architecture. Sasha holds B.Sc. degrees in Computer Science and Physics and M.Sc. degree in Applied Statistics and Astrophysics from Tel-Aviv University, Israel.

Yin Gao, Vice Chairman of 3GPP RAN3, ZTE Corporation, China

Yin Gao received the Master degree in Circuit and System from Xidian University, Xi’an, China, in 2005. She attended the Xidian University where she received his B.Sc. in Electronic Engineering in 2002. Since 2005 she has been with research center of ZTE and is engaged in the study of 3G/4G/5G technology, especially in both LTE and 5G RAN architecture and higher layer signaling procedures. From August, 2017, she was elected as 3GPP RAN3 Vice Chairman.
