None of Wireless Mobile Communications
Commercial satellite launch industry to form a new technology, namely wireless technology. This system uses the system microwave or infrared laser. Microwave systems are effective, mempu accommodate a variety of information with a large channel capacity, nemun transmission can be interrupted by heavy rain. Does not require FCC license as microwave systems, wireless technology with infrared lasers tend to be cheaper and safer but prone to fog and other atmospheric layer conditions.

With affordable prices to its function as a worldwide telephone, cellular phone is growing. Impaired range of land and other man-made obstacles restricting the activity of cellular phones and the Specific Absorption Rate (SAR) is high are also harmful to health. Personal communications services (PCS) is a service in meeting the communication needs of the people to move where (mobile). Systems for third generation (3G) with high-speed data access and communication tools to reach the satellite and terrestrial network also supports mobile communication.
