Isethelayithi Ifoni "Iridium", "Thuraya": ezibekiweko lobuchwepheshe kanye nokubuyekeza

Ukuqala kokusetshenziswa ekudaleni umqondo amanethiwekhi siqu sihlinzekela isigaba lolubanti lwetinsita, ngaphansi kwesiqubulo esithi "noma kuphi, nganoma isiphi isikhathi" ku olulodwa izinombolo zokubhalisa. Umsebenzi eyenziwa ngesisekelo ukuhlanganiswa global amanethiwekhi okuxhumana mobile ekhona futhi ekhiqizwa satellite esinqunyiwe kanye eliwumhlaba, ukudalwa ezikhumulweni ekhethekile ukuhlinzeka namazinga esibonakalayo futhi zokuxhumana yezifiso. Njengengxenye nokuhlanganiswa ifoni satellite unesikhundla ekhethekile ngoba inikeza Ukusabalala global.

Ubuhlobo yonke

Esikhathini ukuqonda abantu abaningi, satellite - uyinto exotic kusukela James Bond movie. Eqinisweni, i-satellite umakhalekhukhwini ube izigidi zabantu emhlabeni wonke abadinga ukuba ucingo amahora angu-24 ngosuku, izinsuku ezingu-365 ngonyaka noma yikuphi emhlabeni. Ngokuvamile, ababhalisile eziningi izinkampani ezinikeza isikhala ukuxhumana, kukhona osomabhizinisi, abaphathi bezinkampani ezinkulu, izinhlangano zikahulumeni, izazi zokuma komhlaba, wabahloli, abahambi, okungenani - abantu abavamile abahlala ezindaweni ezikude.

Siqu zokuxhumana satellite uhlelo (LMSS)

Kusukela ngo-1985, i-International Telecommunication Union isungule umqondo kwembulunga yonke futhi ngesikhathi esifanayo ngezifiso zokuxhumana embulungeni yonke. Ngemva kweminyaka engu-10 eBuenos Aires baba nomhlangano eyingqopha global lapho i-scope ne kwemigomo global ulwazi ingqalasizinda zavunyelwa. It yakhiwa uhlelo olulodwa oxhumene of "Ifoni siqu - satellite -. Wezokuxhumana eliwumhlaba"

Ekubhekaneni izinkinga kwembulunga yonke futhi ukwenziwa ukuxhumana yesandla zinhlelo uwukuphela kwekhambi kwezomnotho iphila ngokuxhumanisa ezingafinyeleleki, eemfundeni ezikude futhi elingenabo abantu abaningi emhlabeni.
