The growth of our economy depends on a well connected workforce and networked infrastructure. There is also increasing demand for these connections to be made anytime, anywhere: that is, wirelessly.
Wireless technologies are also a hot topic in the research world due to the emergence of the wireless internet.
Problems with current wireless networks and internet technologies include:
CSIRO's researchers are developing the fundamental technologies of future broadband wireless and fibre backbone networks.
lack of spectrum
low data rates.
CSIRO’s information and communication technologies (ICT) researchers are developing the fundamental technologies of future broadband wireless and fibre backbone networks.
Our research aims to:
facilitate integration of different networks
increase network reliability
deliver higher speed wireless data transfer
improve quality of wireless network and internet access services.
Much of our work revolves around developing cognitive networks. These are made of intelligent nodes that are smart, aware and adaptable. They are not centrally managed, but negotiate among themselves to deliver information with improved link reliability, coverage and capacity.
For example, for end-users holding a Blackberry, PDA or iPhone, a cognitive wireless network would mean their device would adapt to available network coverage to give them the best access to services.
To create these cognitive networks, we are developing:
antennas that reconfigure themselves to make the most efficient and flexible use of the radio spectrum. Also, wideband, low cost microwave and millimetre subsystems (the wider bandwidth at millimetre frequencies means data-rich information such as video can be transmitted wirelessly at up to 20 gigabits per second).
scalable rate management protocols (RMP) at the internet protocol (IP) network layer. The aim is to enable multi-service internet applications such as browsing, collaborative application, distant learning, peer-to-peer, voice and video streaming to run concurrently with guaranteed quality of service.
Our current work builds on the major intellectual property and know-how we've built up in:
orthogonal frequency division multiplexing (OFDM)
multiple input, multiple output (MIMO) wireless communications
adaptive digital beamforming
monolithic microwave integrated circuit (MMIC).
Broadband communications networks are a critical enabling technology and a major contributor to national productivity and growth.
We are developing advanced solutions to connect people over wired and wireless networks with higher bandwidth and reliability – even those in rural and remote areas.
Our research has impact in the following areas:
We have established partnerships with organisations including:
And tertiary institutions such as:
CSIRO generated one of the most important patents in wireless history: high speed wireless local area networks (WLAN), which underpins the international standard (IEEE 802.11).
Our recent breakthroughs in gigabit wireless and adaptive wireless led to three awards:
Engineering Excellence Award, Engineers Australia, 2007
CSIRO Chairman’s Medal, 2007
CSIRO Strategic Excellence Award, 2007.
CSIRO is developing wireless technologies to bring Broadband to the bush.
