LTE-Advanced mobile networks' speed slower than claimed

SEOUL, Dec. 30 (Yonhap) -- The speed of the Long Term Evolution-Advanced (LTE-A) mobile network isn't quite living up to its hype, a government report showed Monday.

The Ministry of Science, ICT and Future Planning said the average download speed of LTE-Advanced services provided by the country's three major mobile carriers SK Telecom Co., KT Corp. and LG Uplus Corp. came to 47.2 megabits per second (Mbps), hovering far below the advertised up-to-150 Mbps.

SK Telecom's LTE-Advanced network posted the relatively fastest speed of 56.2 Mbps, trailed by KT with 50.3 Mbps and LG Uplus with 43.1 Mbps. Their upload speed came to 18 Mbps, 15.3 Mbps and 13.3 Mbps, respectively.

The advanced LTE, which bundles two frequency bands to increase bandwidth, has been promoted by the firms as the state-of-the-art mobile service offering speeds twice as fast as the existing LTE network.

LTE services with wider bandwidth, which are currently provided only by SK Telecom and KT, were measured to be the fastest existing mobile network, with download speeds of 56.6 Mbps and an upload speed of 20.2 Mbps.

The ministry did not reveal specific data per each company on the wider bandwidth service, saying there was no meaningful difference between the two.

The average download speed of traditional LTE services averaged 30.9 Mbps, with SK Telecom posting the fastest speed of 34.5 Mbps, followed by KT with 30.7 Mbps and LG Uplus with 27.4 Mbps, the ministry said.
