Achievements: Wireless Technologies
CSIRO researchers have demonstrated the fastest and most efficient wireless link ever achieved.
The Wireless Technologies team have demonstrated a multi-gigabit link which performed at over 6 gigabits per second over a point to point wireless connection with the highest efficiency (2.4bits/s/Hz) ever achieved for such a system.
Multi-gigabit links operate at speeds that leave current wireless networks far behind. For example the entire works of Shakespeare could be transmitted over this 6 gigabit link in under seven thousandths of a second or a full DVD movie in just over three quarters of a second.
At the demonstration, the team transmitted 16 simultaneous streams of DVD quality video over a 250 metre link with no loss of quality or delays. This impressive demonstration nevertheless only utilises one quarter of the capacity of the link. More Information Wireless LAN
A team from the CSIRO ICT Centre has demonstrated a
world-first combination of high speed and bandwidth efficiency for wireless
data transfer
Using a system of multiple transmitters and receivers,
wireless data packets were sent and received successfully at 486 Mbps (megabits
per second) with a bandwidth efficiency of over 12 bps/Hz, the first time this
combination of speed and efficiency has been achieved in a public
demonstration.
In wireless data transfer, efficiency is at least as
important as speed as it means that scarce spectrum can be utilised more
productively.
CSIRO has shown that, using existing spectrum, multiple
input/multiple output (MIMO) systems can deliver a substantial boost over what
wireless users enjoy now. More Information
Innovative antenna
design
CSIRO has a long and distinguished history in the design and
construction of antenna systems having provided solutions for organisations in
over 20 countries worldwide.
The MultiBeam Antenna is one example of an innovative CSIRO antenna
design. This novel concept allows up to
19 satellites can be accessed simultaneously in fixed orbits, over multiple
frequency bands.
Another innovation is the development of an advanced multiband
feed system which exploits the ability of existing and proposed satellites to
operate at several frequency bands simultaneously. This capability has been
developed for the Australian Defence Force’s transportable satellite terminals
which, until now, could operate in only one band at a time.
It is envisaged that CSIRO’s new multiband feed system will
be applicable to other communications systems. More Information
