South Korean mobile network operators SK Telecom (SKT) and LG Uplus have both separately revealed plans to deploy an upgraded 4G service later this year which they claim will offer speeds up to four times faster than possible with standard Long Term Evolution (LTE).
In a press release market leader SKT said it had successfully developed what it termed ‘LTE-Advanced 3band Carrier Aggregation (CA)’, which it said aggregates three bands – 20MHz + 10MHz + 10MHz – to support speeds of up to 300Mbps. With LTE-Advanced 3band CA expected to be commercialised by the end of 2014, SKT has said it plans to showcase the technology at MWC 2014, to be held in Barcelona next month. At the global exhibition, the cellco has confirmed it will demonstrate 450Mbps LTE-A by aggregating three component carriers (20MHz + 20MHz + 20MHz).
Meanwhile, GlobalPost reports that LG Uplus plans to roll out higher speeds via the combining of a 40MHz block of spectrum in the 2.6GHz band, a 20MHz block in the 800MHz band and a 20MHz block of 2100MHz frequencies. South Korea’s smallest cellco by subscribers, LG Uplus was cited as saying of its plans: ‘The 3band CA technology marks another progress from wider-bandwidth LTE-A service, and our demonstration proves our technology competitiveness … The service will be available by the end of this year, with facilities and devices supporting the network under development.’
