How It Works

In 1992, the U.S. Federal Communications Commission (FCC) allocated a spectrum in the "S" band (2.3 GHz) for nationwide broadcasting of satellite-based Digital Audio Radio Service (DARS). Of the four companies that applied for licenses, only two were granted rights to broadcast; Sirius (formerly CD Radio) and XM (formerly American Mobile Radio). Each company has satellites in orbit above the earth to transmit their programming. Programs are beamed to one of the satellites, which then transmits the signal to the ground, where your radio receiver picks up one of the channels within the signal. Signals are also be beamed to ground repeaters for listeners in urban areas where the satellite signal can be interrupted.

In many ways, Sirius has set the tone for the industry, being the first to offer commercial free programming on all its music channels and has larger selection of receivers, adapters and other products. XM has a cheaper subscription fee, at least for its basic plan, which offers much the same fare as its competitor.

Both providers have partnered with automobile manufacturers to offer satellite radio in new car models. And each has systems that will search the channels for your favorite music and alert you when and where the songs are playing. Choosing between the two companies can be difficult since each has its advantages. Here is some information that may help listeners choose between the two.
