Document Summary
These satellites orbit the earth at distances between 500 km and 2,000 km and can provide global roaming. These satellites orbit the earth at distances of about. These satellites orbit the earth at distances of about 35,800 km. They have a large coverage area and can handle large amounts of data. A cellular network is a wireless network consisting of multiple wireless networking areas called cells. Each cell is a star topology network equipped with a major base station (bs) as the central transceiver device located in the center of the cell. Each base station interfaces all the wireless communications of the cell. Each cell is assigned a small frequency band and is served by a base station. Neighboring cells are assigned different frequencies to avoid interference. However, the transmitted power is low, and frequencies can be reused over cells separated by large distances.
