Scientists in the United States are touting new technology that will allow Wi-Fi to transfer huge amounts of data over a very short distance.
Georgia Tech professor Joy Laskar and other scientists at the Georgia Electronic Design Center (GEDC) have used extremely high radio frequencies to transfer very large data files.
Traditionally Bluetooth and Wi-Fi have been considered efficient for transferring small amounts of data between gadgets, but neither technology is well suited for rapidly transferring large files, such as high-definition video.
The GEDC used a high frequency in the 60GHz band, and have achieved wireless data-transfer rates of 15Gbits/s over a span of one metre, according to the Associated Press. That translates into a download time of less than five seconds for a DVD-quality copy of a typical Hollywood movie.
The researchers believe these high frequencies are an untapped resource, as permission is not needed from the US government to use this spectrum, which (like Wi-Fi) is unlicensed.
“Certainly, the higher up the spectrum you go, the larger the amount of data you can carry,” said a spokesman for Ofcom in the UK. “But the problem is that the range is very limited.”
He pointed out the similarities of the high frequency technology to UWB (ultra-wideband) technology, which is finally reaching the market after years of wrangling between different engineering bodies and companies.
