As the velocity of online radio reaches its peak, new methods of tactful transmission are appearing. By far the most popular and effective is FM relay of the RealAudio signal, something that has adopted by a number of local stations looking to get involved in this breaking new medium.

The next step up is to satellite radio, more complex, more expensive, but more potential listeners. CD Radio Inc., for example, have deploying a terrestrial repeater network in San Francisco, with testing planned for the middle of October.

Last year, CD Radio was granted one of two U.S. satellite radio broadcast licenses. The company is also building a satellite-to-car 100 channel radio system for the broadcast of music and other programming to motorists throughout the U.S. As part of its system, CD Radio is installing terrestrial repeaters to provide coverage in urban cores where its satellite signals cannot be received. Construction of the repeater network will be completed over the course of the next 12 months, the company said.

So, to take your audiophonica to a truly global audience, you better jack into your nearest lump of silicon in the sky and uplink your urban utopia to the masses.
