More recently, he has also been involved in research on short-range systems, such as Bluetooth and wireless LAN. He holds an M.S. in electrical engineering from Linköping University and a Ph.D. in radio communication systems from the Royal Institute of Technology, Stockholm.
Magnus Fyro joined Ericsson in 1989, working with AXE development—system design, testing and implementation—both for fixed and mobile systems. In 1996, he moved to Strategic Product Management, were he began working with MSCs for the TDMA standard, and in 1998, he began working with Strategic Product Management for GPRS and UMTS packet data. He holds an M.S. in physics engineering from the Linköping Institute of Technology.
Kai Heikkinen is currently the manager of product management at the media gateway node product unit at Core Network Mobile Systems. Before this, he worked with the AXE Centrex solution, GSM design, and PDC local product management. Kai holds an M.S. in electrical engineering from the Helsinki University of Technology, Finland.
Per Johansson is a researcher at Ericsson SwitchLab—an applied research laboratory within Ericsson Research. He holds Master of Science and Licentiate degrees in electrical engineering. He joined Ericsson, in 1992, to work with traffic management and performance analysis of ATM networks, but later moved into research on wireless systems. Since 1998, his research has focused on ad hoc networks—in particular, on Bluetooth ad hoc networking.
Andy Johnston is a master software designer at Ericsson Eurolab Deutschland. He worked on the initial research of the WebOnAir Information Server and later served as product architect. He is currently a system manager for the Ericsson WISE Portal at Ericsson Radio Systems in Stockholm as well as design manager for Mobile Portal Technologies at Ericsson Eurolab Deutschland. He holds a B.S. in computer science from Dublin City University, Ireland.
Magnus Karlson currently serves as the Product Manager for Ronja within the Open Systems CNCP subcore unit. Since joining Ericsson, in 1992, he has worked mostly with product management and support issues for middleware software platforms and frameworks. He holds a B.S. in system analysis from the University of Stockholm, Sweden.
David Kemp is a senior software designer at Ericsson Pty Australia’s ASAC center. He helped develop the architecture of the WebOnAir Information Server and later served as the product architect for the WebOnAir Channel Studio. David has been with Ericsson for over two years. He has a Ph.D. in computer science from the University of Melbourne, Australia.
Seungtai Kim joined Ericsson in 1998 to work as a system design engineer for WCDMA systems. In his assignment at the WCDMA Radio Access Network System Design unit, he helps assess the performance of the WCDMA evaluation system and develops radio network algorithms. He previously worked as a system engineer, optimizing and developing IS-95 systems in Korea.
Peter Larsson is a researcher at the Ericsson Research air interface architecture group. He holds an M.S. degree in physics engineering from Royal Institute of Technology, Stockholm. He joined Ericsson in 1995 as a trainee, working with the system development of GSM access network nodes as well as performing research on and developing testbeds for wireless ATM systems. He is currently engaged in research pertaining to ad hoc networking with emphasis on issues that relate to the lower-layer protocol.
Anders Lundqvist, who joined Ericsson in 1997, is currently the manager of the Radio Access unit at WCDMA Radio Access Network Design. He has also worked with the system design of Ericsson’s WCDMA evaluation system and served as Ericsson’s technical coordinator of the joint Ericsson-Telia WCDMA evaluation project. Anders holds an M.S. in computer science and technology, and a Ph.D. in electrical engineering, both from the Linköping Institute of Technology, Sweden.
Anders Milén currently works at the WCDMA Radio Access Network System Design unit. He joined Ericsson in 1993, working first with GSM radio base station support and system integration, and then with radio network design and investigations. Anders holds an M.S. in electrical engineering from the Lund Institute of Technology.
Niilo Musikka who joined Ericsson 1976, is an Expert in base station systems. He currently works with the design of GSM base station systems, specifically IP-based BSS. He has experience of PBX and private mobile radio systems, but since 1989, he has worked mainly with GSM systems. Niilo holds an M.S. in electrical engineering from the Royal Institute of Technology, Stockholm, Sweden.
Thomas Papanikolaou joined Ericsson in 1999 to work as technical architect and chief developer of the Web-OnAir Information Server, and later became its system manager. He is currently the system manager for the Ericsson WISE Portal presentation layer. Thomas has a Ph.D. in computer science from the University of Saarbrücken, Germany.
Lars-Göran Petersen is an Expert in switching technologies. During the 1960s and 1970s, he worked with ferrite core memory and the design of analog and digital circuits. During the 1980s, he helped develop the architecture of the AXE 212 central processor. During the 1990s, he worked with ATM and IP switching and was one of the initiators of the next-generation Cello packet platform. He currently works with IP system management for this platform.
Lennart Rinnbäck, who joined Ericsson 1982, is a Senior Specialist in GSM BSS system design at Ericsson Radio Systems.
