VHF band and TRS 800MHz band have been used for domestic railway wireless network to manage the railway operation. As it is operated by three different methods(VHF/TRSASTRO/ TRS-TETRA), it is inefficient. Although the wireless network has been used for the train control system, the system has the risk of interference and hacking due to using of the 2.4GHz non-license band. So, MLTM(Ministry of Land, Transport and Maritime Affairs) is planning to build the integrated wireless network for railways. This research is deal with the review of domestic and foreign integrated wireless network for railway. It will be used for the efficient building plan of the integrated wireless network for railways.
