Inkcazo:
Intambo ebanzi yefowuni, ebizwa ngokuba yiWWAN (kwi-Wireless Wide Area Network), iyigama eliqhelekileyo elisetyenziselwa ukuchaza ukufikelela kwi-intanethi ngokukhawuleza kwiinkonzo eziphathekayo ezixhobo eziphathekayo . Ukuba unesicwangciso sedatha kwifowuni yakho ekuvumela ukuba i-imeyile okanye uvakashele iiwebhusayithi kumnathali we- 3G wenkonzo yeselula, leyo yintambo ebanzi yebhanki. Iinkonzo zesebhandi zesebhanki zingabonelela nge-intanethi kwi-laptop yakho okanye kwi- netbook usebenzisa amakhadi enethwekhi omnatha womnatha weselula okanye ezinye izixhobo zonxibelelwano eziphathekayo , njengeemodemu ze-USB okanye ii- hotspots eziphathekayo eziphathekayo . Le nkonzo ye-intanethi ngokukhawuleza iya kudlalwa ngamanethiwekhi amakhulu (umz., Verizon, Sprint, AT & T, kunye neT-Mobile).
3G vs 4G vs WiMax vs EV-DO ...
Mhlawumbi uvile ezininzi izibhengezo ezikhankanywe ngokubhekiselele kwi-bandband ebanzi: GPRS, 3G, HSDPA, LTE, WiMAX, EV-DO, njl ... Leyo yonke imilinganiselo eyahlukileyo - yebhanti ebanzi. Kanye njengoko inethiwekhi engenazintambo ivela kwi-802.11b ukuya kuma-802.11n ngokukhawuleza ngokukhawuleza kunye nezinye iimpawu zokusebenza eziphuculweyo, ukusebenza kwe-mobile broadband kuqhubela phambili, kwaye kunye nabadlali abaninzi kangaka kule ntsimi ekhulayo, iteknoloji ibandakanyeka. I-4G (yesine isizukulwana) ebanzi ebanzi, ebandakanya imigangatho ye- WiMax kunye ne- LTE , ithathe i-fastest (kude kube ngoku) iteration of intanethi ye-intanethi.
Izinzuzo kunye nezixhobo zeBhanki yeBroadband
I-3G ikhawuleza ngokwaneleyo yokusakaza amavidiyo e-inthanethi, ukulanda umculo, ukubukela i-albhamu yezithombe zeWebhu kunye ne- video conferencing . Ukuba uke wafumana u-3G ukuya kwinqanaba le- GPRS ephantsi, uya kuxabisa ngokwenene inkonzo yakho ye- 3G xa uyifumana. I-4G ithembisa ukufika kwi-10 isivinini se-3G, okwangoku ichazwe ngamashishini eselula njengemigangatho yokukhuphela ye-700 Kbps ukuya kwi-1.7 Mbps kunye nokukhawuleza ukulayishwa kwama-500 Kbps ukuya kwi-1.2 Mbps - kungekhona nje ngokukhawuleza njengoko kufakwe kwi-modem ye-cable okanye i-FiOS, kodwa malunga nokukhawuleza njenge-DSL. Qaphela ukuba isantya siya kuhluka ngeemeko ezininzi ezinjengegunya lakho lesignali.
Ngaphandle kokufikelela kwi-Intanethi ngokukhawuleza, i-broadband ye-mobile inikeza inkululeko engenazintambo kunye nokulula, iimpawu zeteknoloji entsha ezithandwayo ngokukodwa ngabaqeqeshi bezithuthi. Esikhundleni sokuba ufune - kwaye ube ngokomzimba kwi- hotspot engena - wireless , ukufikelela kwakho kwi-inthanethi kuhamba nawe. Oku kubaluleke kakhulu ukuhamba, kunye nokusebenza kwindawo ezingavamile (njengepaki okanye kwimoto). Ngokutsho koPhando lwe-Forrester, "Naliphi na ixesha, naluphi na uxhumo lwe-intanethi lunokunika abasebenzi abasemsebenzini ngeeyure ezili-11 ezongezelelweyo zokuvelisa ngeveki" (umthombo: Gobi)
