KT to debut Net service 3 times faster than ADSL Korea Telecom will debut a new broadband Internet service that is theoretically three times faster than the current asymmetric digital subscriber line (ADSL). Called the very-high-bit-rate digital subscriber line (VDSL), the Internet service will be tested today in apartment complexes in Apkujong-dong, southern Seoul, and Tonam-dong, northern Seoul. The VDSL system transmits text, voice and video data at a maximum speed of 26Mbps. Using asymmetric lines, the system receives data at a rate of 13-52 Mbps and sends at rates 1.6-6.4Mbps. In symmetric types the speed is 13-26Mbps for both down and up loading. This represents a three times faster speed than ADSL, the company said. "The new service will offer an ideal Web connection for those who want to have freely enjoy multimedia service, Webcasting and video on demand service," said an official of KT. The company plans to provide a full commercial service by late September and expand its service to cover all of Seoul and Kyonggi Province by the end of the year. The price has yet to be set, but the firm said it was considering various charges for more consumer choice and to broaden its user base quickly. The advantage VDSL has is that it can achieve high-speed Internet access in older buildings by using a combination of high-speed fiber-optic lines of larger networks and the traditional phone lines to transmit data. Another distinguishing feature of VDSL is that the transmission speed is even, both down and upstream, meaning that the speed at which the Internet is accessed is equal to the speed at which the user sends out information. Currently, apartment buildings built before 1985 cannot receive ADSL service, which is provided over fiber-optic cables. Cable modem access is the only option for them but subscribers to those services experience a considerable slow-down in speed when there are a large number of subscribers in a given area.
