Claim:
A digital satellite radio system comprising: a content server for providing a plurality of digital satellite radio channels; at least one satellite for broadcasting the plurality of digital satellite radio channels; at least one terrestrial repeater for broadcasting the plurality of digital satellite radio channels; at least one microrepeater for receiving a selected digital satellite radio channel from said content server while not receiving unselected digital satellite radio channels, and wirelessly broadcasting the selected digital satellite radio channel in a different waveform as used by said at least one terrestrial repeater but using a same physical layer, the selected digital satellite radio channel having either a first frequency corresponding to a first ensemble of channels or a second frequency corresponding to a second ensemble of channels; at least one digital satellite radio unit for receiving the plurality of digital satellite radio channels from said at least one satellite and said at least one terrestrial repeater, and for receiving the selected digital satellite radio channel from said at least one microrepeater while not receiving the unselected digital satellite radio channels; and wherein if said at least one micro-repeater detects an adjacent micro-repeater transmitting on the first or second frequency, then said at least one micro-repeater changes the frequency of the selected digital satellite radio channel for said at least one digital satellite radio unit so that it is different from the frequency used by the adjacent micro-repeater.
