Zusammenfassung:	PURPOSE: A basement wireless network integrated relay device is provided to reduce a transceiving antenna which is installed on the ground. CONSTITUTION: A remote management server(60) remotely performs monitoring and controlling state of relay units(12,14,24,34) through a failure detection unit(50). The remote management server performs urgent broadcasting through an integrated emergency broadcasting unit(40). A wideband wireless relay unit relays a wideband wireless signal. A complex TV relay unit relays a broadcasting signal of an analog TV, a digital TV, a ground wave DMB, or satellite TV. A complex TV transmitting unit(36) transmits an output signal of the complex TV transmitting unit.
