South Korea's SK Telecom has announced a pilot trial that uses LTE services in both the 800MHz and 1.8GHz frequency bands in the area from Gangnam Station to Kyobo Tower Crossroads and also revealed plans for its commercial launch in July 2012.
The mobile network said that the use of Multi Carrier (MC) secures twice the frequency bandwidth to boost mobile broadband speeds.
The company developed MC technology to utilize both its existing 800MHz frequency band and the 1.8GHz band it newly acquired in the second half of last year. With an additional 20MHz uplink/downlink spectrum, it will be using a total of 40MHz for its LTE services.
The biggest strength of MC lies in that it allows the use of additional frequency bands and enables effective and efficient use of frequencies. As it chooses the faster one between the two frequency bands for LTE communications, mobile data traffic is optimally distributed to each frequency band, preventing network overload.
The commercialization of MC is to begin in July 2012, with plans to cover the whole Seoul area within 2012 and 23 other major cities by early 2013.
The use of the 1800Mhz band will also enable SK Telecom to support LTE roaming with other networks.
Kwon Hyuk-Sang, Executive Vice President and Head of Network Division at SK Telecom said, "SK Telecom will provide the fastest and the most reliable LTE service through the world's first adoption of the innovative Multi Carrier technology that allows for the use of twice wider frequency bandwidth than its competitors in Korea."
