Iifowuni zeDijithali "ii-smartphones" zixhobo ezixhamla kumadivayisi ase-intanethi. Ukuba ixhomekeke kwikhompyutheni yakho ngokufanelekileyo, inokusebenza njengemodem yenethiwekhi yenjongo jikelele. Ukusebenzisa ifowuni yakho njengemodem inikeza indlela yokufumana uxhumano lwe-intanethi xa kukho konke okunye okufana neendawo zokuhlala ze-Wi-Fi . Ngelishwa, ukusebenza kwesi sixhobo soxhumo lwenethiwekhi kungenakuhlangabezana neemfuno zomntu.
Inqanaba lokudlulisa idatha eliphezulu lwedatha elixhaswa yi-modem yefowuni iyahluka ngokuxhomekeka kwimilinganiselo yokunxibelelana yakho yeenkonzo zefoni .
Ukusebenza ngokubanzi kwizizukulwana ze-Technology Technology
Ubuchwephesha benethiwekhi yobuchwephesha banamhlanje buwela phantsi kwe "3G", "3.5G" okanye "4G". Ezi ziquka i- LTE , i- HSPA , EV-DO , kunye ne- EDGE . Ubuchwepheshe be-3G banikela ngokubanzi phakathi kwe-0.5 Mbps kunye ne-4 Mbps ukulandwa. I-3.5G kunye ne-4G inikezela kwi-10 Mbps (kwaye ngamanye amaxesha aphezulu) ukulandwa.
Ngokwahlukileyo, ubuchwephesha beeteknoloji eziseleyo (ngokukhawuleza ukuba zingasebenzi kwiindawo ezininzi eziphuhlisiweyo zehlabathi) njengeGPRS (ngokuqhelekileyo ithathwa njengesi-"2.5G"), i-CDMA ne-GSM inikezela ngesivinini esezantsi ngaphaya kwe-100 Kbps okanye ngaphantsi, okufana nokusebenza komnxeba we-analog kwi-modem ye-Intanethi.
Ukwenziwa komsebenzi (kunye nomgangatho) wokunxibelelana kweeseli kuyahluka kakhulu kubanikezeli benkonzo, indawo yokuhlala kunye nomthwalo (inani lababhalisi abakhutheleyo) kwindawo ethile. Ngenxa yezi zizathu, isantya esiphezulu okanye somgangatho wee-intanethi kaninzi asisebenzisi.
Iingqinisiso ngokubhekiselele kuSebenzi lweModem yeNtsebenzo
Njengokuba kuninzi nemigangatho yokunxibelelana, abasebenzisi beemodem zefowuni akufanele balindelwe ukufezekisa ubuninzi bezobugcisa ekusebenzeni. I- bandwidth yangempela oya kuyonwaba ixhomekeka kwizinto eziliqela:
- Umgangatho wesignal wireless signal (ngokuqhelekileyo, umgama kude ne-cell tower esondeleyo)
- Ukuthungelwano kwenethiwekhi kwintengiso yomnxeba wefowuni
- Inkcazelo yomgaqo-nkqubo womnxibelelwano wenethwekhi oqeshwe ngumboneleli, kunye naliphi na ukulinganiselwa kwezobugcisa okanye izandiso abazenzayo
- Ukuxuba kwendlela esezantsi kunye nezantsi ezenzayo (iimodemu zeefowuni zenkxaso zixhasa inkxaso engaphantsi kweendlela zokulayisha ngaphandle kokulandelwa)
Kwakhona, cinga ukuba "isantya" senoma iyiphi intanethi ayixhomeki kuphela kwisixa soxhasano oluxhaswayo kodwa nakwi-latency yayo. I-modem yefowuni ixhamla kwi- latency ephakamileyo kakhulu enikezelwa yindlela yokuxhumana kwayo. Xa usebenzisa i-cell phone yakho njengemodem, kufuneka ulindele ukubona ukulibaziseka okukhawulezayo kunye nokugqithiswa kwedatha yokudluliselwa kwedatha, okunciphisa isivinini esikubonayo soxhumo lwakho nangaphezulu.
