Satellite Radio

The technology for broadcasting digital radio via satellite has been developed several years ago. During the infancy days of satellite radio, companies like Dish Network have given digital audio channels as part of their package. But only recently has the satellite radio picked up. When travelling in a car or boat etc. one couldn't receive satellite radio. This was the main reason why the general public was not aware and was not interested in the satellite radio. The situation and technology is different today. Today, we can get digital audio satellite broadcasts by using a small, GPS-like antenna. Due to this satellite radio has gained popularity and vehicle owners feel that this is a good option for music while on the move. There are several advantages of satellite radio. Some of them are (1) You are not limited by geographical locations. (2) You don't have to switch radio stations when you leave a certain coverage area. (3) There are no noise disturbances, which are heard in the traditional AM and FM broadcasts. There are some problems as well with satellite radio. One main problem is that you need to be in the line of sight of the satellite to receive the transmission. There were problems when you had different objects like trees etc. intervening with the direct transmission. As a solution to this problem, they installed land based devices in order to eliminate the lack of direct satellite transmission. Another interesting difference between the traditional radio and satellite radio was that the satellite radio charged advertisers a subscription fee, as opposed to charging the advertisers for airing their commercials. This worked well for a lot of advertisers, since they get a 100% content broadcast without the intrusion of about 10-15 minutes of commercials.
