XM provided digital programming directly from two high-powered satellites in geostationary orbit above the equator: XM Rhythm at 85° west longitude and XM Blues at 115° west longitude in addition to a network of ground-based repeaters. The combination of two satellites and a ground-based repeater network was designed to provide gap-free coverage anywhere within the contiguous U.S., the southern tip of Alaska, and in the southern part of Canada. The signal could also be received in the Caribbean Islands and most of Mexico (reports have stated that areas north of Acapulco were able to receive a steady signal); however, XM is not yet licensed for reception by paid subscribers living in these areas.
