South Korean operator LG Uplus has demonstrated its new LTE network, which the company claims to be eight times faster than the original LTE, The Korea Times reports. LG Uplus claims the new network, LTE in Unlicensed spectrum (LTE-U), can transmit data at up to 600 Mbps. "We took a big step forward in the LTE technology race again by realizing the 600 Mbps, the fastest data transmission speed used in a commercial mobile network, following the world's first development and demonstration of a LTE-U network," said LG Uplus Service Development Division head Lee Sang-min.
LG Uplus has combined the 60 MHz bandwidth in the 5.8 GHz spectrum and 20 MHz bandwidth in the broadband LTE spectrum using carrier aggregation technology. The operator plans to expand the use of the 5.8 GHz unlicensed spectrum to 80 MHz bandwidth, up from 60 MHz, to achieve data download speeds of 750 Mbps.
LG Uplus plans to commercialize the LTE-U network once mobile phones that support the faster transmission speed are launched on the local market.
The operator also said it has finished the verification process for an even more advanced CA technology that supports data download speeds of up to 800 Mbps. This technology divides data to a Wi-Fi spectrum and LTE spectrum and then transmits it to handsets, the company added.
