CSIRO scientist wins top award for wifi technology                                

ALMOST two decades after pioneering high-speed wireless now used by almost a billion people each day, John O'Sullivan has taken out one of the country's top science gongs.                                                                                         The CSIRO scientist has been awarded the prestigious Prime Minister's Prizefor Science for 2009 for his wifi technology now found in millions of aptops, printers, wireless access devices and even Nintendo's Wii.

One of Australia's most significant scientific breakthroughs, Dr O'Sullivan and his team found a way to speed up wireless networks in 1992 - a problem that had previously kept international scientists stumped.

The idea has since generated a massive windfall for the CSIRO to the tune of $205 million and counting.

Dr O'Sullivan - an astronomer, physicist and self-proclaimed "nerd" -received $300,000 and a gold medallion in recognition of his efforts at a gala event in Canberra today.
                       
Prime Minister Kevin Rudd said the nod recognised Dr O'Sullivan's major contribution to astronomy as well as his groundbreaking wifi technology.

"The techniques developed became a core of fast wireless local area network or wireless technology - technology that is used across the world in more than 800 million devices and counting," he said.

Dr O'Sullivan and the CSIRO team beat 22 international labs to solve the"multipath" problem - or the interference caused by reflected radio waves which slows down network speeds.

They found a way to accelerate them by splitting radio channels apart, essentially turning a one-lane road into a super highway and making wireless about five times faster.

"John and his team found the solution," Mr Rudd said.

"Their patented invention is now built into international standards and into computers, printers, smart phones and other devices used by hundreds of millions of people every day."

Mr Rudd called it one of the most significant achievements in CSIRO's 83-year history and said it illustrated how scientific research can be turned into real and practical solutions.

But recognition has been a long time coming.

The CSIRO was forced to wage a long-running legal battle against big computer companies such as Microsoft for using the technology for free.

"After a decade-long legal battle ... I would like to publicly congratulate the tenacity of the CSIRO board and legal team in pursuing this particular intellectual copyright," Mr Rudd said.

Out-of-court settlements and lucrative licensing deals have given the CSIRO one ofits best performing inventions, from which it is contributing $150million back into science research.

Dr O'Sullivan said the idea was born out of a need to "cut the wires".

"And to cut the wires, we needed to make it as fast as the wires," he said.

Seeing the technology in use in millions of devices around the globe, "I can't help but feel proud," he said.

"Even though we thought it had huge potential, I'm just blown away with how many applications there are now."

There search had begun with the aim of exploring radio waves from exploding black holes, which technically speaking, did not reach fruition.

But it proved that you should always "shoot for the stars, and even if you miss, you might end up with something pretty special", Dr O'Sullivan said during his acceptance speech.

Among the other winners on the night, Michael Cowley took out the Science Minister's Prize for Life Scientist of the Year for breaking the link between fat and diabetes, while Amanda Barnard was named the Physical Scientist of the Year for her work in nanotechnology.




Kalau tak macam kura-kura lah gamaknya nak surf internet.

macam kura2 tu cemana? rasanya teknologi wifi takde kene mengena dgn internet.

zaman dulu2, org lain pakai LAN (networking) utk mudahkan transfer data dan utk berhubung dgn server dan printer. internet takde pun. cuba imagine internet masih takde, wifi masih berguna utk wireless networking (WLAN) dan ianya menjimatkan kos dari segi penyediaan infra (pasang kabel, pasang port, face plate, etc). kalo dah wifi, nak renovate opis pun senang, takde tarik2 wayar lagi dah. tapi security pulak le yg jadi risiko - takut kena hack...

yg perlu kita faham ialah wifi ni ialah teknologi networking (LAN) tanpa wayar.
contohnya wifi 11g (speed dia 54mbps). itu ialah kelajuan networking. kelajuan transfer file dari 1 pc ke 1pc yg lain.
internet cuma 1% aje kot (streamyx 1mbps). kita forum ni mungkin 50kbps aje kita guna.

wireless fidelity (Wi Fi) punya speed paling rendah yg aku tau ialah 5mbps-11mbps. (kategori 11a).
internet yg kita guna, cuma 1mbps (maximum) kalu stakat forum, email, youtube, mungkin la kot 80kbps.
even download movie dari rapidshare pun paling laju 200kbps, mungkin 1% aje dari 11mbps wifi tu.

alhamdulillah skrg dah ada 11n = cecah 300mbps
tapi blom buleh lawan kabel punya GigabitLAN (1gbps atau 1,000mbps)
paling best, 100Gb ethernet (fiber optic) : http://en.wikipedia.org/wiki/100_Gigabit_Ethernet
