LG Uplus demonstrates LTE-U technology, records 600Mbps downlink speeds

8 May 2015

LG Uplus, South Korea’s smallest cellco by subscribers, has demonstrated faster mobile broadband speeds using technology termed as LTE in Unlicensed spectrum (LTE-U), the Korea Times reports. It has been revealed that the mobile network operator is utilising frequencies in the 5.8GHz band, which has been used for Wi-Fi services, in conjunction with some of its existing LTE spectrum to allow for theoretical downlink speeds of up to 600Mbps. To achieve such speeds the company is said to have combined 60MHz in the 5.8GHz band with a 20MHz block of spectrum in an unconfirmed band, more traditionally used for LTE-based services. According to LG Uplus the 5.8GHz unlicensed spectrum is expected to improve mobile network speed and quality because it can be used for telecom services other than Wi-Fi without restriction if the services meet the technological qualification for the spectrum. Looking ahead, the cellco has said it plans to expand the use of the 5.8GHz unlicensed spectrum to 80MHz bandwidth with a view to realising downlink speeds of 750Mbps. A commercial launch of the technology meanwhile is expected once handsets that will support the increased download rates are available.
