Vessels floating on the open seas, as well as people in places such as remote islands, mountainous areas, and disaster-stricken sites, will now be able to benefit from a newly developed technology that enables smooth communication based on transmission modes that are changeable depending on surrounding environments.
As part of a project to develop adaptive satellite broadcast and telecommunications transmission technology sponsored by the Ministry of Science, ICT and Future Planning, ETRI and Network Customizing Technologies(CEO : An Myeong-su) successfully developed the core technology for a second-generation satellite communications modem that enables high-speed satellite Internet services at 20Mbps.
This technology alters the transmission mode according to climatic conditions to enhance communications efficiency, by increasing the transmission speed with satellites from a maximum of 4Mbps with the first-generation modem to 20 Mbps and reception performance from tens of Mbps to 100Mbps.
ETRI is planning to additionally develop transmitting/receiving devices, satellite access control equipment, network operation equipment, and satellite terminals to be used at satellite hubs installed at telecommunications companies, and to complete an entire system by the end of 2015.
This technology is also capable of being utilized for temporary communications in areas where communications infrastructure has been destroyed due to typhoons, earthquakes, or other natural disasters by using the Mugunghwa and Cheollian Satellites with the Ku/Ka bandwidth(12-14 GHz/20-30GHz).
