Therefore multiple such satellites direct your Phone Number List call to the required destination. On the other hand, LEOs provide better communication clarity than geostationary satellites, because of the inherent delay that it introduce. The least delay Phone Number List with such satellites is 0.5 seconds and this is a major disadvantage of geo stationary satellites. In case of satellite phones communicating with geostationary satellites, the main disadvantage Phone Number List is that, the phone requires a large antenna system for signal transmission and reception. In such cases, the antenna needs to be of high gain, which needs more power to operate.
Consequently the size of the phone also increases Phone Number List and can be compared to the size of terrestrial mobile phones in the past, relative to the current tiny terrestrial mobile phones. Satellite phones require a clear view of the sky to operate and will not function inside a building, car or a boat. It would require external antenna system to operate in such Phone Number List environments. This is clearly a serious disadvantage. In working of a cellular phone, the principle is based on dividing an area into zones or base stations called 'cells'. As you communicate Phone Number List while you move, you leave a particular zone and enter another.
Your call is handed over from your previous cell Phone Number List where you were, to the new one where you are currently passing through. Your communication is electronically switched to the cell where you are in. Every cell phone and your Sim card with hold adequate information regarding the identity of your mobile handset and therefore the Phone Number List network is aware of where to locate you when you are leaving one cell and entering the other. In remote areas, such communication is not possible owing to the absence of cellular network. You may Phone Number List have experienced that, while using your mobile handset, as you passed different zones, at a particular area, you lose your connection.
