Satellite systems are ideally suited for television and radio distribution, providing high-quality, high-reliability, low-maintenance, flexible alternatives to terrestrial systems. Unlike terrestrial microwave systems, there are no towers or repeaters to maintain, no radio fades to degrade performance, no extensive troubleshooting to diagnose problems and far less land to lease. Your capital investment for a satellite network is also much lower, especially in areas with difficult terrain. Receive stations can be deployed in a fraction of the ti ....etc

Satellite digital radio is a radio system, which is specially designed for car radios. The operation of the satellite digital radio is that satellite receives the data generated by uplink station, amplify this data and send it back through special spot beam not only to fixed but also to mobile and portable receivers. complementary terrestrial transmitter may be necessary, because in big cities high rise buildings may block the signals from the satellites. In this seminars, an attempt is made to explain the different existing satellite systems, ....etc

In the last sixty years we’ve evolved from radio, to black and white TV, to color TV, to cable TV and the satellite TV universe. Now that opportunity is expanding even further with TV on mobile phones, representing the ability to reach millions of consumers in new ways. Mobile digital broadcast TV combines the two best-selling consumer products in history-TVs and mobile phones. Indeed, TV will be the ingredient that drives demand for the next generation of wireless mobile phones because consumers want both communications and entertainment a ....etc

Abstract
LEO is Low Earth Orbit satellite.It circulates on a lower orbit in a shorter period . Additionally LEO systems try to ensure a high elevation for every spot of the earth to provide a highquality communication page link . The networks will play an important role in the evolving information infrastructure . It provides communication with shorter endto- end delays and e_ciency frequency usages . Some problems need to be solved before LEO satellite system can be successfully deployed . One of these problems is handover management . Even ....etc

We all have our favorite radio stations that we preset into our car radios, flipping between them as we drive to and from work, on errands and around town. But when travel too far away from the source station, the signal breaks up and fades into static. Most radio signals can only travel about 30 or 40 miles from their source. On long trips that find you passing through different cities, you might have to change radio stations every hour or so as the signals fade in and out.

Now, imagine a radio station that can broadcast its s ....etc
