SK Telecom to build 1.8GHz base stations to offer 150Mbps of speeds on LTE

SK Telecom today said it will build additional 1.8GHz base stations to offer 150Mbps of speeds on LTE and LTE-Advanced networks.

SK Telecom 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.

The telecom operator in Korea can also expand coverage throughout the nation by the end of this year.

SK Telecom to expand LTE speed

SK Telecom has already built a nationwide LTE network using 10MHz in the 800MHz frequency band in April, 2012.

The nationwide rollout of this 20MHz LTE will provide the company with an important edge in deploying nationwide “20MHz (1.8GHz) + 10MHz (800MHz)” LTE-Advanced 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 secures LTE bandwidth in three different frequency bands — 10MHz in 800MHz band, 20MHz in 1.8GHz band and 10MHz in 2.1GHz band.

LTE-Advanced tri-band carrier aggregation technology will support SK Telecom to offer up to 300Mbps speed to Korean mobile subscribers.
