SK Telecom Outlines Plans to Boost LTE Networks and Prepare for 300Mbps Speeds

Published on:

South Korea's SK Telecom has announced that it will build additional 1800Mhz base stations to secure nationwide coverage for its LTE and LTE A networks by the end of this year.

As SK Telecom already built a nationwide LTE network using 10MHz of it 800MHz frequency band in April, 2012, the nationwide rollout of this 20MHz LTE will provide the company with an edge in deploying nationwide "20MHz (1.8GHz) + 10MHz (800MHz)" LTE-A network that offers up to 225Mbps of speed.

Moreover, the company also said that it gained approval to use 10MHz bandwidth in the 2.1GHz band for LTE. The company secured 30MHz bandwidth in the 2.1GHz band through a frequency auction in 2010.

With the newly added 10 MHz LTE bandwidth in the 2.1GHz band, SK Telecom now secures LTE bandwidth in three different frequency bands - i.e. 10MHz in 800MHz band, 20MHz in 1.8GHz band and 10MHz in 2.1GHz band - thus moving one step closer to realizing LTE-A tri-band carrier aggregation technology that supports up to 300Mbps.

SK Telecom said that it will begin building base stations for LTE in the 2.1GHz band in the second quarter of 2014, making the network available for commercialization as soon as the supporting handsets come to market. At present, chipset that support 300Mbps of speed is being developed. Until then, SK Telecom will apply Multi Carrier technology to these 2.1GHz base stations to relieve the burden of its existing LTE networks.
