SEOUL, March 12 (Yonhap) -- A group of South Korean scientists has developed a new radio frequency (RF) chip that can allow wireless transmission of large amounts of data to and from a small device, such as a cellular phone, at a much faster speed than any conventional means, the government said Tuesday.
The new RF chip, developed by a team from the Korea Advanced Institute of Science and Technology (KAIST), uses the 60 Gigahertz (Ghz) waveband to send or receive 10 gigabits or 10 billion bits of data per second, according to the Ministry of Education, Science and Technology.
Such speed had never been seen before in any other technology using wireless devices such as Wi-Fi, let alone cable-based technologies, it said.
The new RF Chip can transmit a 4.7-gigabyte movie file in just 3.76 seconds while the same file takes over 3 minutes to be sent through Wi-Fi and over 200 minutes by a bluetooth device.
"It is a key new technology that can greatly increase the competitiveness of the country's smartphones. The chip can also replace various cables that existing televisions require, which means it can be used not only in smartphones but also in other mobile devices, such as cameras," Park Cheol-soon, a KAIST professor in charge of the research, was quoted as saying.
The ministry said the team was also able to minimize the size of the new RF chip for use in small mobile devices by needing only one antenna for transmission of both outgoing and incoming data, unlike conventional RF chips.
