Covers selection of modern phone "Transfer" "swap" and "access" three most technology simplifies some associated with the practical application of mobile phone technology is not theoretical derivation and calculation process, highlighting the theoretical knowledge and the development of cutting-edge phase combine ideas. The mountains and the desert, no matter how good the phone is just decoration. There can be able to send and receive signals in the Earth anywhere phone? To achieve this, the best way is to use a low Earth orbit satellite phone system, first developed by satellite telephone system is the famous "Iridium" star system, before the introduction of "Iridium" star system, let's look back Look satellite phone development process. Back in October 1945, the British high-end mobile phone accessories were recovered, 0 'Clark propose ideas geostationary satellite phones. He has published in the United Kingdom (Radio World> Magazine Article 10, entitled "^ relay satellite extraterrestrial provide radio coverage worldwide?"
