South Korea’s LG Uplus has demonstrated its energy self-sufficient LTE network base stations for mountainous and remote island areas, the Korea Times reports. Showing off the technology at a base station at the Sky Ranch in Daegwallyeong, Gangwon Province, the telco claimed that the system, which integrates LG Electronics’ solar panels and LG Chem’s energy storage system (ESS) batteries, would not only improve network conditions in remote radio shadow zones but also minimise environmental damage. The demo facility in Daegwallyeong is LG Uplus’ fourth solar-powered LTE base station; the cellco established and began testing the same systems at Mount Gyeryong and Mount Oseo in South Chungcheong Province last year.
While South Korean cellcos are said to have mobile coverage of 99.9% of the population, geographic coverage is notably lower, standing at around 80%, in part due to the fact there are some 4,440 mountains and 3,677 islands nationwide. LG Uplus has suggested that the energy self-sufficient base stations will boost connectivity in radio shadow zones and can be used for emergency situations such as rescue operations in natural disasters and accidents, while it also expects the technology to help it obtain government permission to build such facilities in environmental protection zones such as national parks.
Commenting on the technology development, Heo Vitus, Network Strategy Unit Vice President at LG Uplus, was cited as saying: ‘With this base station system, we can now connect LTE networks even in remote areas where cable-based networks are practically impossible to build … This will boost both cost-efficiency and eco-friendliness in expanding LTE networks in radio shadow zones.’
