Mountains and desert Huawei cell phone ringing recovery, even the best cell phone just decoration. There is no energy can send and receive signals at the Earth anywhere phone? To achieve this, the best way is to use a low Earth orbit satellite phone system Sony phones ringing recovery, first developed satellite telephone system is known as 'Iridium' star system, before the introduction of 'Iridium' star system, we First go back to the satellite phone of development. As early as October 1945, the British people, 0 'Clark propose ideas geostationary satellite phones. He has published in the United Kingdom (Radio World> magazine 10 entitled "Relay ^ extraterrestrial satellites capable of providing radio coverage worldwide?" The article, for the first time reveals the possibility of human use of satellite phones. Then in 1954 7 US Navy use of the moon surface reflection of radio waves on the planet two telephone transmission tests successfully tested after 1956 between Washington and Hawaii to establish a mobile phone business. The world's first October 4, 1957 Sputnik launch, officially opened the Wei Huang phone off. In 1990, Motorola (qe -⑴ dagger) has introduced a new concept of global personal mobile phone ^ 'Iridium' star system 'diamond' star system by the US Motorola Mobile Systems satellite phone unit design, preparation of operational satellites in low-Earth orbit by composition, in combination with the existing mobile phone network, enabling global digital personal mobile phones. China's readers 'Iridium' star system will not be unfamiliar, first because 66 satellite phones throughout the 'Iridium' star system partly borne by the China Great Wall Industry Corporation of Long March 2 (730 rocket mission; second professional phone ringing recovery, because the 'Iridium' tragic fate satellite system major media repeatedly been rendered 'Iridium' star system is a very large low-orbit satellite network, spare man running total of 72 satellite phones satellite network [66 satellites and six in orbit 780 km high from the ground On the track, constitute the six inclination of the orbital plane 86 Shu 4. satellite in orbit around the Earth is the period of 100 minutes and 28 seconds. mass of each satellite about 700 kg on each satellite 48 a launching point for transmitting mobile phone signals whole 'Iridium' satellite systems and 'Iridium' star itself are by the company responsible for the design, 'Iridium' star system client handheld devices ('Iridium' Stars phones) are by the company and Professional hand-held phone maker Kyocera of Japan (clever. 3] provide it, 'silver' Star phone into only 丨 ... ⑴ !!! systems for mobile phones and 03 single-function machines' mobile networks / 1 "丨 the 0111 Composite mode two kinds. The latter can not only be used as a satellite phone, but also used as a cellular wireless phone. When a 'Iridium' satellite subscriber calls another 'Iridium' Iridium satellite users' satellite system will be through the entire 'Iridium' satellite network Location to be called 'Iridium' satellite customers., then the signal will be 051 ^ 1 network is turned on the user's inner if the called user is located in a ground 03 ^ / 1 system calls range through the ground 03 ^ 1 channel [If the Users with compatible 'Iridium' star calls like the above scenario eight. And if you can not locate in the terrestrial telephone network, the signal will be directly between the satellite and satellite transmission, until transferred to the called 'Iridium' star system users the 'Iridium' star calls. So, as long as both sides call using the 'Iridium' satellite phone, regardless of the user in the Antarctic or the Arctic, the times certainly call establishment, reflecting the 'Iridium' Stars in the power of personal mobile phones Samsung note4 ringing recovery, recycling Ningxia ringing Obo Obo electronic is supplied by Shenzhen Electronic Technology Co., Ltd. Shenzhen City Aobo Electronic Technology Co., Ltd. (www.aobodz.com) strong, credible, and so on in Shenzhen, Guangdong Other industry has accumulated a large number of loyal customers.
