Az 1960-as \u00e9vekbeli t\u00e9v\u00e9sorozat rajong\u00f3i Star Trek<\/i> el\u00e1multak, amikor l\u00e1tt\u00e1k, hogy Kirk kapit\u00e1ny kinyit egy apr\u00f3, k\u00e9zben tarthat\u00f3 telefont, hogy besz\u00e9ljen \u0171rhaj\u00f3ja leg\u00e9nys\u00e9g\u00e9vel. Ma a mobiltelefonok m\u00e1r nem tartoznak a tudom\u00e1nyos fantasztikum vil\u00e1g\u00e1ba. B\u00e1rhov\u00e1 is menj\u00fcnk a F\u00f6ld\u00f6n, a sarkvid\u00e9kekt\u0151l az \u00f3ce\u00e1n k\u00f6zep\u00e9ig, telefonon kereszt\u00fcl kapcsolatot tarthatunk. A leg\u00fajabb modellekkel e-maileket is k\u00fcldhet\u00fcnk, \u00e9s az interneten is b\u00f6ng\u00e9szhet\u00fcnk.<\/p>\n<\/div>\n

Ezt a kommunik\u00e1ci\u00f3s forradalmat a m\u0171holdas technol\u00f3gia bevezet\u00e9se tette lehet\u0151v\u00e9. Az 1960-as \u00e9vek k\u00f6zep\u00e9ig a telefonh\u00edv\u00e1sokat f\u00f6ldi r\u00e1di\u00f3kapcsolatok \u00e9s k\u00e1belek seg\u00edts\u00e9g\u00e9vel bonyol\u00edtott\u00e1k le. Ennek ellen\u00e9re korl\u00e1tok voltak arra n\u00e9zve, hogy h\u00e1ny h\u00edv\u00e1st lehetett kezelni.<\/p>\n

Ezut\u00e1n megjelentek az els\u0151 t\u00e1vk\u00f6zl\u00e9si m\u0171holdak. Az egyenl\u00edt\u0151 felett k\u00f6r\u00fclbel\u00fcl 36 000 km-es magass\u00e1gban, geostacion\u00e1rius p\u00e1ly\u00e1n kering\u0151 m\u0171holdak k\u00e9pesek voltak dr\u00e1ga ad\u00f3- \u00e9s k\u00e1belh\u00e1l\u00f3zat n\u00e9lk\u00fcl m\u0171k\u00f6dni. K\u00f6nnyed\u00e9n \u00f6sszek\u00f6thatt\u00e1k a h\u00edv\u00f3kat az \u00f3ce\u00e1n vagy a hegyl\u00e1nc mindk\u00e9t oldal\u00e1n. Az 1965-ben p\u00e1ly\u00e1ra \u00e1ll\u00edtott Early Bird egyszerre 240 telefonh\u00edv\u00e1st tudott kezelni. Ma egy nagy kommunik\u00e1ci\u00f3s m\u0171hold t\u00f6bb sz\u00e1zezer telefonh\u00edv\u00e1st is k\u00e9pes kezelni.<\/p>\n

Az elm\u00falt \u00e9vekben \u00fajabb forradalom zajlott le az alacsony vagy k\u00f6zepes F\u00f6ld k\u00f6r\u00fcli p\u00e1ly\u00e1ra \u00e1ll\u00edtott kis m\u0171holdflott\u00e1k bevezet\u00e9s\u00e9vel. Mivel t\u00f6bb tucat ilyen m\u0171hold rep\u00fcl k\u00fcl\u00f6nb\u00f6z\u0151 p\u00e1ly\u00e1kon, a horizont felett mindig t\u00f6bb m\u0171hold is tal\u00e1lhat\u00f3, amelyek k\u00e9pesek fogadni a mobil eszk\u00f6z\u00f6kr\u0151l \u00e9rkez\u0151 h\u00edv\u00e1sokat.
