V technick\u00fdch \u0161pecifik\u00e1ci\u00e1ch telef\u00f3nov, tabletov n\u00e1jdete, ak\u00e9 mobiln\u00e9 siete zariadenie podporuje, napr\u00edklad podporu 2G, 3G, 4G a najnov\u0161ie aj 5G. Ak v\u00e1s to zauj\u00edma, stru\u010dne a ve\u013emi jednoducho v\u00e1m poviem, ak\u00fd je rozdiel medzi t\u00fdmito \u0161tandardmi mobilnej komunik\u00e1cie.<\/p>\n\n\n\n
2G je tradi\u010dn\u00e9 mobiln\u00e9 telefonovanie, SMS a mo\u017enos\u0165 pou\u017e\u00edva\u0165 telef\u00f3n ako n\u00edzkor\u00fdchlostn\u00fd modem na pripojenie k internetu. Bol to prv\u00fd masov\u00fd digit\u00e1lny \u0161tandard pre mobiln\u00fa komunik\u00e1ciu. Nahradil anal\u00f3gov\u00e9 tradi\u010dn\u00e9 syst\u00e9my. 2G umo\u017e\u0148uje telefonova\u0165, posiela\u0165 textov\u00e9 spr\u00e1vy a pristupova\u0165 k internetu, ale je ve\u013emi pomal\u00fd, m\u00f4\u017eete len prezera\u0165 web. R\u00fdchlos\u0165 je nedostato\u010dn\u00e1 na prenos videa, tak\u017ee nebudete m\u00f4c\u0165 sledova\u0165 Youtube a in\u00e9 streamovacie slu\u017eby.<\/p>\n\n\n\n
3G je \u0161tandard, ktor\u00fd pri\u0161iel po 2G a v\u00e4\u010d\u0161inou funguje na in\u00fdch frekvenci\u00e1ch ako 2G. Vo v\u00e4\u010d\u0161ine kraj\u00edn bol 3G zaveden\u00fd ako doplnok k 2G. V\u010faka pr\u00edchodu \u0161tandardu 3G bolo mo\u017en\u00e9 uskuto\u010d\u0148ova\u0165 videohovory a z\u00edska\u0165 vysokor\u00fdchlostn\u00e9 internetov\u00e9 pripojenie (v z\u00e1vislosti od zariadenia, ktor\u00e9 pou\u017e\u00edva oper\u00e1tor, m\u00f4\u017eete teoreticky z\u00edska\u0165 pr\u00edstupov\u00fa r\u00fdchlos\u0165 pribli\u017ene 7,5 Mbit\/s. V praxi sa v\u0161ak r\u00fdchlos\u0165 internetu pohybuje okolo 2 – 4 Mbit\/s. R\u00fdchlos\u0165 internetu nebola dostato\u010dn\u00e1 na stabiln\u00fd prenos videa. Vo v\u00e4\u010d\u0161ine pr\u00edpadov v\u0161ak bolo viac-menej mo\u017en\u00e9 vyu\u017e\u00edva\u0165 slu\u017eby streamovania.<\/p>\n\n\n\n
4G je \u0161tandard zalo\u017een\u00fd v\u00fdlu\u010dne na prenose inform\u00e1ci\u00ed. Ak sa hovor uskuto\u010d\u0148uje prostredn\u00edctvom 4G, konvertuje sa do paketov a prid\u00e1va sa k paketom inform\u00e1ci\u00ed pren\u00e1\u0161an\u00fdch cez internet. D\u00f4vodom vytvorenia tohto \u0161tandardu bola potreba r\u00fdchleho prenosu inform\u00e1ci\u00ed cez internet. Pod\u013ea \u0161pecifik\u00e1cie 4G \u0161tandard podporuje r\u00fdchlosti 40 Mbit\/s alebo 100 Mbit\/s v z\u00e1vislosti od typu zariadenia a kapacity p\u00e1sma kan\u00e1la. Pod\u013ea mnoh\u00fdch zdrojov v praxi r\u00fdchlos\u0165 prenosu \u00fadajov z\u00e1vis\u00ed od vzdialenosti zariadenia od z\u00e1klad\u0148ovej stanice, ale v\u017edy poskytuje r\u00fdchlos\u0165 4 a\u017e 30 Mbit\/s. V\u010faka sieti 4G m\u00f4\u017eete vo\u013ene vyu\u017e\u00edva\u0165 slu\u017eby streamovania.<\/p>\n\n\n\n
5G je nov\u00fd \u0161tandard, ktor\u00fd poskytuje r\u00fdchlos\u0165 internetu 1 a\u017e 2 Gb\/s. Jeho spustenie si vy\u017eaduje ve\u013emi hlbok\u00fa moderniz\u00e1ciu existuj\u00facej mobilnej siete, z\u00e1klad\u0148ov\u00e9 stanice s\u00fa od seba vzdialen\u00e9 400-500 metrov (1300-1500 st\u00f4p). V praxi tento \u0161tandard za\u010dalo zav\u00e1dza\u0165 len nieko\u013eko mobiln\u00fdch oper\u00e1torov, zvy\u010dajne vo vysoko rozvinut\u00fdch krajin\u00e1ch. V\u00e4\u010d\u0161ina oper\u00e1torov v\u0161ak tento \u0161tandard pova\u017euje za nepotrebn\u00fd. Existuj\u00faci \u0161tandard 4G umo\u017e\u0148uje uspokoji\u0165 potreby 98 % pou\u017e\u00edvate\u013eov mobiln\u00fdch telef\u00f3nov. Teraz teda nastala ve\u013emi zauj\u00edmav\u00e1 situ\u00e1cia, telef\u00f3ny podporuj\u00fa 5G, ale sie\u0165 5G nemus\u00ed by\u0165 vo va\u0161ej krajine dostupn\u00e1.<\/p>\n\n\n\n
Norma je vo v\u00fdvoji, ale v bl\u00edzkej bud\u00facnosti nebude \u017eiadan\u00e1. Sie\u0165 5G e\u0161te nebola implementovan\u00e1, tak\u017ee vytvorenie siet\u00ed 6G je vo vzdialenej bud\u00facnosti a tak\u00e9to r\u00fdchlosti nie s\u00fa pre be\u017en\u00e9ho pou\u017e\u00edvate\u013ea potrebn\u00e9.
