Mo\u017en\u00e1 to zn\u00e1te z vlastn\u00ed zku\u0161enosti – telefonujete a pot\u0159ebujete si b\u011bhem hovoru rychle n\u011bco vyhledat na internetu. Jen\u017ee ouha – data nefunguj\u00ed. Pro\u010d k tomu doch\u00e1z\u00ed a jak tento probl\u00e9m vy\u0159e\u0161it? Vysv\u011btl\u00edme v\u00e1m, pro\u010d b\u011bhem hovoru nefunguj\u00ed mobiln\u00ed data<\/b>.<\/p>\n

N\u00ed\u017ee uveden\u00e9 postupy jsou prim\u00e1rn\u011b ur\u010deny pro telefony Xiaomi, Redmi a Poco s grafickou nadstavbou HyperOS<\/b>. Ta je aktu\u00e1ln\u011b \u0161\u00ed\u0159ena formou aktualizace na vybran\u00e1 za\u0159\u00edzen\u00ed. Aktu\u00e1ln\u011b je tak\u00e9 dostupn\u00e1 na t\u00e9m\u011b\u0159 v\u0161ech telefonech, kter\u00e9 nab\u00edz\u00edme v na\u0161em \u010desk\u00e9m<\/a> i slovensk\u00e9m<\/a> e-shopu.<\/p>\n

Li\u0161\u00ed se to podle mobiln\u00ed s\u00edt\u011b<\/h2>\n

Mobiln\u00ed s\u00edt\u011b pro\u0161ly od sv\u00e9ho vzniku dramatick\u00fdm v\u00fdvojem. Zat\u00edmco prvn\u00ed generace (1G) umo\u017e\u0148ovala pouze analogov\u00e9 hlasov\u00e9 hovory, druh\u00e1 generace (2G) p\u0159inesla digitalizaci a s n\u00ed i mo\u017enost pos\u00edlat SMS zpr\u00e1vy a vyu\u017e\u00edvat z\u00e1kladn\u00ed datov\u00e9 slu\u017eby. T\u0159et\u00ed generace (3G) pak otev\u0159ela dve\u0159e skute\u010dn\u00e9mu mobiln\u00edmu internetu a \u010dtvrt\u00e1 (4G\/LTE) jej v\u00fdrazn\u011b zrychlila.<\/p>\n

\"Pro\u010d<\/a>
Pro\u010d b\u011bhem hovoru nefunguj\u00ed mobiln\u00ed data?<\/figcaption><\/figure>\n

Kdy\u017e telefonujete a z\u00e1rove\u0148 chcete pou\u017e\u00edvat internet, mus\u00ed v\u00e1\u0161 telefon zvl\u00e1dnout ob\u011b \u010dinnosti sou\u010dasn\u011b. To ale nen\u00ed v\u017edy mo\u017en\u00e9<\/b>. Pokud hovor prob\u00edh\u00e1 p\u0159es star\u0161\u00ed 2G s\u00ed\u0165, data b\u011bhem n\u011bj jednodu\u0161e fungovat nebudou. Je to d\u00e1no technologick\u00fdm omezen\u00edm t\u00e9to s\u00edt\u011b, kter\u00e1 byla prim\u00e1rn\u011b navr\u017eena pro p\u0159enos hlasu.<\/p>\n

V p\u0159\u00edpad\u011b modern\u00edch s\u00edt\u00ed na\u0161t\u011bst\u00ed existuje \u0159e\u0161en\u00ed v podob\u011b technologie VoLTE (Voice over LTE)<\/b>. Jak napov\u00edd\u00e1 jej\u00ed n\u00e1zev, jde o p\u0159enos hlasu p\u0159es s\u00ed\u0165 LTE, tedy 4G. Kdy\u017e m\u00e1te VoLTE aktivn\u00ed, m\u016f\u017eete b\u011bhem hovoru bez probl\u00e9m\u016f surfovat po internetu. Nav\u00edc z\u00edsk\u00e1te i dal\u0161\u00ed v\u00fdhody – hovor se spoj\u00ed do dvou sekund a kvalita zvuku bude d\u00edky HD Voice v\u00fdrazn\u011b lep\u0161\u00ed.<\/p>\n

Pro zaj\u00edmavost – zat\u00edmco 2G s\u00ed\u0165 nab\u00edz\u00ed maxim\u00e1ln\u00ed rychlost jen 0,3 Mb\/s, 4G zvl\u00e1dne a\u017e 1000 Mb\/s. To je jeden z d\u016fvod\u016f, pro\u010d je VoLTE tak v\u00fdhodn\u00e9 – krom\u011b mo\u017enosti sou\u010dasn\u00e9ho vol\u00e1n\u00ed a datov\u00e1n\u00ed z\u00edsk\u00e1te i mnohem vy\u0161\u0161\u00ed rychlost p\u0159ipojen\u00ed.<\/p>\n

Kdy b\u011bhem hovoru funguj\u00ed a nefunguj\u00ed mobiln\u00ed data?<\/h2>\n

2G s\u00ed\u0165 (G, E, EDGE)<\/h3>\n
    \n
  • Data b\u011bhem hovoru nikdy nefunguj\u00ed<\/li>\n
  • 2G s\u00ed\u0165 m\u00e1 nejlep\u0161\u00ed pokryt\u00ed pro hlasov\u00e9 hovory (99,8 % \u00fazem\u00ed \u010cR)<\/li>\n
  • Technicky jde o s\u00edt\u011b GPRS (2.5G) a EDGE (2.75G)<\/li>\n<\/ul>\n

    3G s\u00ed\u0165<\/h3>\n
      \n
    • Data a hovory funguj\u00ed sou\u010dasn\u011b<\/li>\n
    • Tato s\u00ed\u0165 je ji\u017e u v\u011bt\u0161iny oper\u00e1tor\u016f vypnut\u00e1 nebo se jej\u00ed vypnut\u00ed pl\u00e1nuje<\/li>\n<\/ul>\n

      4G s\u00ed\u0165 (LTE)<\/h3>\n

      • Data funguj\u00ed b\u011bhem hovoru pouze p\u0159i aktivn\u00edm VoLTE<\/li>\n
      • Bez VoLTE data b\u011bhem hovoru nefunguj\u00ed<\/li>\n
      • P\u0159i p\u0159echodu z LTE do oblasti se slab\u00fdm sign\u00e1lem se hovor automaticky p\u0159epne do 2G a data p\u0159estanou fungovat<\/li>\n
      • Po n\u00e1vratu do oblasti s LTE sign\u00e1lem se hovor u\u017e zp\u011bt do LTE nep\u0159epne a data z\u016fstanou nefunk\u010dn\u00ed<\/li>\n<\/ul>\n

        5G s\u00ed\u0165<\/h3>\n
          \n
        • Data funguj\u00ed b\u011bhem hovoru pouze s aktivn\u00edm VoLTE<\/li>\n
        • Chov\u00e1n\u00ed je obdobn\u00e9 jako u 4G s\u00edt\u011b<\/li>\n<\/ul>\n
