SK Telecom launches LTE-Advanced

SK Telecom yesterday launched the world's first commercial LTE-Advanced network, as ZTE conducted a live demonstration of 1Gbps wireless data transmission.
SK Telecom said its new 150Mbps LTE-Advanced network covers the entire Seoul area and the centers of 42 other cities.
The operator revealed plans to gradually expand this coverage to 84 cities nationwide, without giving a time-frame.
The high-tech network already uses carrier aggregation (CA) and co-ordinated multi point (CoMP) technologies, and SK Telecom plans to apply enhanced inter-cell interference coordination (eICIC) in 2014.
At present, the only smartphone being offered that supports the network is the Samsung Galaxy S4 LTE-A. But SK Telecom aim to add another six compatible smartphones to its line-up this year.
LTE-Advanced activity has been heating up in recent months. To date, 13 operators in 8 markets have committed to deploying LTE-A, according to Wireless Intelligence. Operators including Telstra, Sprint and Yota have pledged to launch this year.
Separately, ZTE yesterday used the Mobile World Asia Expo to demonstrate wireless data rates of 1Gpbs.
The company used CA technology to combine four separate carrier frequencies in the 1.9-GHz an 2.6-GHz bands.
The milestone is an indication of the future potential of LTE-A networks, and for the TD-LTE standard. China Mobile, which last week launched its long-awaited TD-LTE equipment tender, could be a key beneficiary of this multi-band CA technology.
