South Korean Carrier SK Telecom has started commercial roll out of Multi Carrier LTE network in 23 Korean cities. The company claimed they are first carrier to implement the technology commercially. They already started implementing MC network and by the end of 2012 they are pretty confident to wrap up the MC rollover to all 23 cities.
Well, Multi Carrier LTE is a new term to you and me as well. I found couple of resources to understand the basics of this technology. In simple words, just imagine what happens when a traffic lane is divided in to two, one for personal cars and other one for heavy vehicles. Traffic jam is neatly avoided. Isn’t? It is as simple as that, at least in pen and paper. In Multi Carrier LTE network instead of one frequency channel two channels are used. Already established 800 MHz band and lately discovered 1800 MHz (including 20 MHz uplink/downlink spectrum band) band are used together to form a dual channel. Traffic load can be evenly distributed between the two channels. The system can automatically identify the load in one spectrum band and can diversify traffic to other band. Less congestion means better quality of service. LTE can deliver much better speed and superior browsing experience.

The company also claims that a firmware upgrade is required for recent LTE devices. Vega Racer 2 and Samsung Galaxy S III LTE version for South Korea will have the firmware upgrade soon. They also stated that MC LTE radio will be integrated in most smartphones manufactured from now onwards.
Kwon Hyuk-Sang, Executive Vice President and Head of Network Division of SK Telecom said, “SK Telecom will provide the fastest and the most reliable LTE service through the world’s first adoption of the innovative MC technology that allows for the use of twice wider frequency bandwidth than its competitors in Korea.”
