SK Telecom launches world’s first tri-band LTE-A service, 300Mbps performance on tap
At the beginning of 2014, SK Telecom vowed that its network throughput would increase dramatically from speeds of roughly 150Mbps to 225Mbps through the implementation of wideband LTE-A service (aggregating two channels).
Now, SK Telecom has announced that it has commercially launched tri-band LTE-A service, where data speeds can reach a blazing 300Mbps. At peak performance, a 1GB movie should download in less than 30-seconds. The speeds are possible due to aggregating three channels of spectrum, a 20MHz channel at 1.8GHz, a 10MHz channel at 2.1GHz, and a 10MHz channel at 800MHz.
Wideband LTE-A is already available in 84 cities across South Korea, meaning that it has the underpinnings in place to rollout tri-band service aggressively by installing 2.1GHz base stations in those markets. This aggressive network rollout is part of SK Telecom’s roadmap to develop the 5G standard.
The Samsung Galaxy Note 4 S-LTE is the first device that can use the enhanced network, and it is being sold on a select basis to customers who want to be early adopters and provide feedback to SK Telecom about network performance.
