The purpose of present study is to provide an efficient ‘Disaster Emergency
Communication System’ (below DECS) to deal with serious disaster situations in national
levels. Currently, DECSs such as the VHF, UHF, and TRS are worked to control some
disaster situations in the world. However, new system such as for sending the correct image
and big data is more likely to need than current the DECSs in the comtemporary societies.
Several serious disaster events such as the Sam-Poong Department Store Collapse, Daegu
Subway Fire, and Sewol Submerge event, nevertheless, there was not the DECS based on
the field in South Korea. In July 2014, finally, South Korean government started to provide
a PS-LTE system which is the new and one system with fire fighting, police, army, railway.
however, there are no many academic studies for DECSs to deal with disaster situations
in South Korea. The present research highlights to explore an efficient DECS of Korean
styles to fix some national security and public safety. The paper provides three key findings:
first is how to make a unified Korean DECS based on PS-LTE. Second is how to make
sure the frequency of 700MHz levels to communicate in the shady areas. Three is what kinds
of communication facility is adequate for fixing PS-LTE DECS.
