The latest in technology is the satellite Radio. While traveling in the car for work or for pleasure we listen to our favorite Radio program but most signals travel only upto 30 or 40 miles from its source and you loose contact with the Radio. While passing by in different area you will get different channels on Radio.
However, with the advent of Satellite Radio its range has been increased up to about 35,000 km or 22000 miles with high quality and clear voice without breaking. In addition, you can have the choice of 100 channels. Imagine you are driving from one state to another without changing your favorite channel with minimum or no commercials.
The satellite Radio was introduced sometime in 1992 and since then it is in full swing. The United States Federal Communications commissions gave a spectrum of S band for digital Audio Radio Service. The license was give to Sirius Satellite Radio and XM Satellite Radio and World Space. Satellite Radio also known as Digital Radio gives very good quality music from space.
All the three companies have different listeners as the Sirius Satellite Radio, XM are in North America, and the World Space caters to Asia, Europe and Africa. Each of the companies has different broadcasting systems as the radio signals are owned by each separately. The different receivers (Radios) need to be used for different services. The common factor is the satellite, ground repeaters and the receivers.
XM Satellite Radio uses geostationary satellites, which move long with the movement of the earth, and they are usually stationed above the equator. For clear signal, the companies install a network of ground antennas, which receive the signal and retransmit to the subscribers.
Sirius uses satellites that have unique elliptical orbits around Earth. These orbits allow satellites to be higher in the sky and reduces the signal loss due to big buildings or mountains. This also requires less of antennas than that of XM.
The music is in CD and digital format and the Radio Jockey can play their own choice or the listener’s choice at any given time. The services maintain broadcast studios where the artist can perform live. All the songs and other materials are transferred to the satellite in digital format and therefore the signal is of very high quality.
The radio receiver from one Satellite radio will not work in the other ones, as there is a very high technique, which cannot be decoded by the other radios. The receiver units are available at a very good prices which when compared to the quality it is very less. The main feature of the Satellite Radio is that most of the channels are commercial free.
So, go for the Satellite Radio it is the smart way to listen to music. If you enjoy the music, Satellite Radio is for you.
