SK Telecom utilizing Multi Carrier technology to improve LTE service, roaming


South Korean wireless carrier SK Telecom has officially begun the commercial rollout of its Multi Carrier (MC) network. The technology, which will be available in twenty-three cities by the close of 2012, will allow equipped devices to seamlessly wander between the 800MHz and 1.8GHz LTE frequencies (while also adding 20MHz of uplink/downlink spectrum). Aside from improving throughput and coverage within the country, SK hopes the addition of the 1.8GHz frequency to its handsets' repertoire will provide customers with a better LTE roaming experience when abroad -- a handful of Asian and European nations have settled on 1.8GHz as their Long Term Evolution band of choice. New devices, with compatible radios, will be necessary to leverage the Multi Carrier goodness, although the carrier did note that Samsung's ever-popular Galaxy S III would support the hotness. We would like to raise our glass to SK Telecom and offer a toast to the bright future of multi-band high-speed wireless networks. Cheers!
