Prof. David Skellern

RoZetta Institute




David Skellern is an Australian electronic engineer and computer scientist credited, along with colleagues, for the first chip-set implementation of the IEEE 802.11a wireless networking standard.

He is credited with a number of important technology innovations developed with colleagues which include John O’Sullivan, Terence Percival and Neil Weste, and in particular the first chip-set implementation of the IEEE 802.11a wireless networking standard. This innovation has been described as a revolution in world communications, allowing high speed wireless communications.

Skellern was appointed to the Order of Australia in 2012.

He received a B.Sc. University of Sydney (1972) [Pure Mathematics, Computer Science & Physics], a B.E. (Hons), Electrical Engineering, University of Sydney (1974), and a PhD, University of Sydney (1985) for a thesis on A Mapping System for Rotational Synthesis Data.

From 1974 to 1983 he worked in radio astronomy and taught electronics at Sydney University and Macquarie University. From 1983 to 1989 he held research and academic positions at that university’s department of Electrical engineering. In 1989, he became Professor and chair of the Department of Electronics at Macquarie University.

In 1997 he co-founded Radiata, a company engaged in the commercial development of WLAN communications. The company demonstrated the world’s first chip-set implementation of the 54 Mbit/s IEEE 802.11a High-Speed WLAN standard, based on the research Skellern conducted with Neil Weste in the 1990s at Macquarie University in collaboration with CSIRO. Radiata was sold to Cisco Systems in 2001 for $565 million.

When Radiata was acquired by Cisco in 2001. he became the Technology Director of their Wireless Networking Business Unit, until 2005, when he joined NICTA (National Information and Communications Technology Australia Ltd), where he was first chief executive officer (2005–2010) and finally, in 2011, Chairman.

Skellern was involved in debate on sharing of the spectrum which resulted in the allocation of additional 5 GHz spectrum for Wireless Access Systems at the World Radio Conference in 2003 (WRC2003).

He has held visiting faculty and researcher appointments at Imperial College London, Hewlett-Packard Laboratories, Palo Alto, CA, Digital Equipment Corporation Paris Research Labs, France, and British Telecom Research Labs, Martlesham Heath, UK, Visiting Researcher.

He is a Fellow of the Institute of Electrical and Electronics Engineer and the Australian Academy of Technological Sciences and Engineering, and an honorary fellow of the Engineers Australia (Institute of Engineers Australia).

He received the Clunies Ross Award, Australian Academy of Technological Sciences and Engineering in 2010 the MA Sargent Medal, Engineers Australia, the CSIRO Tony Benson Award for Individual Achievement in ICT and the CSIRO Medal, and the Norman W V Hayes Medal, Institute of Radio and Electronic Engineers, 1980.

In 2012, he received the Order of Australia. In 2012, he received an honorary doctorate from Macquarie University.

David Skellern was awarded the 2017 IEEE Masaru Ibuka Consumer Electronics Award (with John O’Sullivan) “for pioneering contributions to high-speed wireless LAN technology.”

He won the 2010 M A Sargent Medal.

Dr. Astrid Algaba Brazalez

Senior Researcher at Ericsson Research


Innovative and highly efficient antenna solutions for next generation communication systems


Astrid Algaba Brazález received the Telecommunication Engineering degree from Miguel Hernández University of Elche, Alicante, Spain, in 2009; and the Licentiate of Engineering and Ph.D. degrees from Chalmers University of Technology, Gothenburg, Sweden, in 2013 and 2015, respectively. She joined Ericsson Research, Gothenburg, Sweden, in November 2014, where she currently works as a Senior Researcher within the Antenna and Microwave Hardware Sector where her work is focused on 5G/6G Advanced Antenna System (AAS) projects. She has been the research leader of all projects related to metasurfaces and lens antenna solutions within Ericsson Research since 2015. Her research interests include millimeter and submillimeter-wave antenna array technologies for 5G/6G radio access applications, lens antennas and radomes, design of microwave passive components such as filters, metasurfaces (based on glide symmetry and gap waveguide technology), system integration of active components and antennas at millimeter-wave frequencies, and design of interconnects, routing methods and transitions to achieve such integration. Her research career can be summarized in more than 50 contributions including top IEEE journal publications, peer-reviewed conferences and patents filed by Ericsson. Astrid Algaba is currently serving as one of the two Swedish delegates and management committee member of the European COST Action SYMAT- CA18223- Future communications with higher-symmetric engineered artificial materials ( She has also been a lecturer and organizer of several European School of Antennas (ESoA) courses like “Antenna Systems for 5G Communication, “Exploiting Symmetries in Artificial Materials for Antenna Applications” and “Metalenses for Antenna Applications”.
