'Iridium' star system is a very large low-orbit satellite network, a total of 72 satellite phone network [66 satellites and six spare satellites in orbit on people running from the ground 780 km high orbit, constitutes 6 an inclination of 86 Shu 4. The orbital plane, the satellite in orbit around the Earth is the period of 100 minutes and 28 seconds. The quality of each satellite is about 700 kilograms, on each satellite has 48 emission points used to transmit mobile phone signals. Whole 'Iridium' star system and 'Iridium' star itself are by the company responsible for the design, the client's 'Iridium' star system handheld devices ('Iridium' satellite phone) is a company specializing in hand-held phone manufacturers and Kyocera of Japan ( Qiao. 3] provide it, 'silver' Star phone into only for Shu ... ⑴ !!! phone system single function machines and 03 'mobile networks / 1 "Shu of 0111 Composite mode two kinds. The latter can not only be used as satellite phone Huawei speaker phone recycling, but also used as a cellular wireless phone. Iridium 'star system will be through the entire' positioning satellite network called 'Iridium When a' Iridium 'satellite subscriber calls another' Iridium 'Stars User Iridium 'satellite users. inside if the called user is located in a ground 03 ^ / 1 system calls range, then the signal will be connected via the ground 051 ^ 1 network for the user 03 ^ 1 channel [If the user is using a compatible' Iridium 'satellite phone as the top eight on the situation. And if you can not locate in the terrestrial telephone network, the signal will be transmitted directly between the satellite and the satellite speakers reclaimed until transfer to be called' Iridium 'star system users' Iridium 'onboard phone. So, as long as both sides call using the' Iridium 'satellite phone Samsung note4 speaker recovery, regardless of the user in the Antarctic or the Arctic, the times certainly call establishment, reflecting the' Iridium 'star power in terms of individual phone capacity. After the mid-19th century, with the telegraph, the telephone invention, discovery of electromagnetic waves Sony speaker phone recycling, mobile phone has a huge field of human fundamental change, we can use the metal wires to transmit information, even by electromagnetic waves for wireless phones so the myth of 'ears' 'clairvoyance' into a reality. Since then, the human information transfer can be derailed by the visual and auditory way, electrical signals as a new carrier, so bring a series of technical innovations, and began The new era of human handsets in this section, we will introduce more than 100 years the most representative of mobile phone technology and the way Apple 5S phone speaker phone recycling |.
