SK Telecom Carries 2G/3G over LTE

SK Telecom has developed and commercialized "2G/3G over LTE" technology -- a world first.

"2G/3G over LTE" enhances the stability of 2G/3G mobile networks by utilizing LTE network as backhaul instead of fixed-line 2G/3G infrastructure. SK Telecom said the wireless backhaul network could prove to be more resilient than fixed-line 2G/3G infrastructure in the event of man-made or natural disasters.  In Korea, mobile networks typically have structural redundancy.  The LTE network can replace one of the two fiber-optic transmission networks in the redundancy network structure, thus enhancing the operator’s network building and operating efficiency.

SK Telecom plans to apply the technology to 600 base stations by 2016.

Choi Seung-won, Senior Vice President and Head of Network Engineering Office said, “With 2G/3G over LTE, SK Telecom’s 2G and 3G customers will be able to experience a more stable and seamless service. Our efforts will continue to keep improving customer satisfaction through new and innovative technologies that enhance the quality of service for all our customers.”

SK Telecom demonstrated live LTE-Advanced Tri-Band Carrier aggregation in its commercial network, achieving downlink speeds of up to 300 Mbps. The demonstration, which was conducted in partnership with Ericsson, combined three separate bands of 10 MHz, 10 MHz and 20 MHz bandwidth.  SK Telecom believes the demonstration will serve as yet another opportunity for the company to solidify its position as a leader in LTE-Advanced.
