A distributed antenna system for providing extended signal coverage within an indoor area is disclosed. In the system, a master unit receives a first modulated signal from an outdoor base transceiver station, and relays the modulated signal to a remote unit through a distribution network. The master unit also receives a base band signal originating outside the indoor area, and transmits the baseband signal to a micro base transceiver station through the distribution network. The micro base transceiver station modulates the base band signal and transmits the modulated base band signal to a terminal unit through an indoor antenna.
