How Satellilte Radio Works

This article was written by Kevin Bonsor for the informational website "HowStuffWorks.com." Bonsor introduces satellite radio, also known as digital radio, and the advantages of using it. He begins by comparing regular radio to satellite radio. The author explains that regular radio typically has a broadcast signal capable of only reaching around 30 to 40 miles, whereas, satellite radio is beamed from space and broadcasts its signal from over 22,000 miles away. This allows you to travel far distances while still listening to the same station. Unlike conventional radio, you do not have to worry about the fading in and out of sounds or the static noise as you are tuning the stations. Bonsor states that with satellite radio you get complete clarity with an "uninterrupted, near CD-quality" sound. Two companies that have adopted this idea are XM Satellite Radio and Sirius Satellite Radio. Numerous car companies have also implemented this innovation by installing satellite radio receivers into their cars. Portable satellite receivers have also been made available at many electric companies.

Before reading this article, I knew absolutely nothing about satellite radio with the exception of Howard Stern having a show on Sirius Satellite Radio. Even so, after discovering more about satellite radio, it seems very convenient -- especially when I'm on long road trips. It makes it easier for drivers to listen to a constant stream of music without the use of mp3 players or lugging around tons of CDs. I also like that many car companies have begun installing satellite radio in cars. Another thing that's convenient about satellite radio is that the receivers are easy to buy. However, I am not quite sure what the cost of the equipment is or how to install it. There is also the question about its necessity. With the emergence of new technology like mp3 players, satellite radio has some stiff competition.

INTRODUCTION:

• Satellite radio is also known as digital radio.
• The signal that is beamed from space is capable of reaching 22,000 miles away meaning you get a constant stream of music.
• XM Satellite Radio and Sirius Satellite Radio provide services.

RELATIVE ADVANTAGE:

• It has a further reach than conventional radio whose signal typically only goes as far as 30 to 40 miles.
• Bonsor points out that satellite radio is uninterrupted and clear with "few or no commercials" and "near CD-quality music."

TRIALABILITY:

• Satellite radio receivers have already been installed in some cars.
• There are several models of portable receivers available at a variety of electronic stores. (442)
