Korean Research Offers Hope of Cutting PC Boot-Up Time
Korean Research Offers Hope of Cutting PC Boot-Up Time
Korean scientists have developed technology that will allow computers to be switched on without the long, tedious booting time. A research team led by Chang Joon-yeon and Koo Hyun-cheol at the Korea Institute of Science and Technology said Thursday they developed a so-called "spin-injected field effect transistor" that can use not only the flow of electrons but also the spinning direction of electrons as computerized information for the first time in the world. Their work is published in Science Magazine on Friday.
"After the theory of spintronics and use of semiconductor in the field emerged in 1990 in the United States, many countries tried to develop technologies to put the theory into practice with a commercial prospect," the team said. "But this is the first time that a spin electron device that can be electrically operated was developed. The repercussions of commercial production throughout information industry would be huge. It will then be possible to turn on a computer without going through the long booting process, and put memory and CPU in one chip."
The researchers have applied for a patent in the U.S., Europe and Japan.

Korea Among World's Top 10 for Wi-Fi Hotspots
Korea Among World's Top 10 for Wi-Fi Hotspots
Korea has the seventh largest number of Wi-Fi locations in the world with 12,814 hotspots as of the first half of this year, a report released on Sunday reveals.
Wi-Fi hotspots are public areas such as hotel lobbies, airports and cafes where a wireless Internet connection is available for wireless LAN (Wi-Fi) devices.
In the list compiled by JiWire, a U.S. mobile media company, the U.S. ranked first with 68,059 Wi-Fi hotspots, followed by China, the U.K., France, Russia and Germany.

Korea Cell providers offer new packages.
Cell providers offer new packages
Local mobile phone operators are showcasing package deals that include mobile, Internet and landline services at a discount.
SK Telecom said yesterday it would launch a “fixed mobile substitution,” or FMS, service starting next month. Customers will be able to designate certain areas in which they can make calls on their cell phones at cheaper landline rates. When in the pre-selected areas, 10 seconds on the phone will cost 13 won ($0.01) instead of the usual 18 won. “We intend to use our competitiveness in mobile services and merge this with landlines to provide a high-quality, low-cost telecom service for our customers,” said Lee Sun-gun, head of marketing at SKT.
Last week, KT, SKT’s biggest rival, launched its fixed mobile convergence, or FMC, product, combining mobile and Internet phone functions in one device, with the aim of cutting the cost to customers. Using FMC, a client can make a call on his or her mobile phone using a regular WCDMA connection - but when in range of a wireless Wi-Fi Internet router, he or she can switch to Internet phone mode on the same device.
There is a downside, however. While SKT’s FMS service allows users to subscribe to the service using their current phone, the FMC package will require users to buy a special new handset.
Comparing the prices of the two packages is difficult. However, KT said that if users that spend, on average, 170 minutes per month on their cell phones were to make 50 percent of those calls through a Wi-Fi connection, they would save around 6,000 won per month.
SKT said that subscribers who pay the basic fee of 21,600 won per month and make half of their calls in their designated areas using FMS will be able to save around 8,640 won per month. The cost to add SKT’s FMS service is 2,000 won per month.
LG Telecom is also planning to launch its own version of the FMC package in January, while SKT said it would introduce a new service that combines the two concepts in one mobile phone.
