Radio broadcasting in the United States has stayed in the background as digital technologies have transformed other media. But now radio is making its own digital leap, with satellite digital radio services set to debut this fall, and a standard for terrestrial digital radio imminent.
The digital transformation will bring a wealth of benefits to radio, with improved signal quality and robustness. Satellite radio will deliver near-CD sound to small receivers--even those in moving vehicles. And AM radio gone digital will offer two-channel stereo and an audio quality comparable to today's analog FM.
IEEE Spectrum looks at the two national satellite radio services about to debut--Sirius Satellite Radio and XM Satellite Radio--and analyzes their similarities and differences. It then lays out the evolution of the terrestrial digital radio standard under development, and looks at the future of these technologies.
