Gateway platform for connecting D-TRS in power IT

TETRA (Terrestrial Trunked Radio) is the standard of DTRS(Digital Trunked Radio System) developed by the ETSI(European Telecommunications Standards Institute). Currently, TETRA has been selected as the power IT wireless backbone network in Korea while the traditional distribution automation system has used the wireless network of mobile service provider using CDMA(Code Division Multiple Access) and WCDMA(Wideband CDMA) modems. Therefore, the development of gateway platform is indispensable according to the change to the TETRA network. In this paper, we propose an embedded Linux-based gateway platform for transmitting industrial power IT protocol using TETRA network.
