I-AirCards inikeza ukuxhumeka kwe-laptop ye-laptop
Uma ungaseduze nendawo yokushisa ye-Wi-Fi, futhi udinga ukuxhumeka kunethiwekhi yakho yehhovisi, ungasebenzisa i-AirCard nge-laptop yakho ukuze ufinyelele ku-intanethi. I-AirCard ikunika ukufinyelela kwe-inthanethi nomaphi lapho ungasebenzisa umakhalekhukhwini wakho.
I-AirCard uhlobo lwemodemu engenantambo esetshenziselwa ukuxhuma amadivayisi weselula kwi-inthanethi ngamanethiwekhi weselula . I-AirCards inikeza ukufinyelela kwi-intanethi kusuka kumakhompyutha ephathekayo angaphandle kwamabala aphezulu we- Wi-Fi . Zingasetshenziswa futhi njengezinye izindlela zesevisi ye-intanethi ye -dial-up ezindaweni zasemakhaya noma kwezinye izindawo ngaphandle kwensizakalo ye-intanethi esheshayo. Ngokuvamile badinga isivumelwano ne-umhlinzeki weselula ngaphezu kwekhontrakthi yakho yeselula ekhona.
Izinhlobo ze-AirCards
Esikhathini esidlule, abahlinzeki bensizakalo yenethiwekhi yeselula bajwayele ukuqoqwa futhi ngezinye izikhathi babuyelwa kabusha imodemu engenantambo ehambisanayo nezinkontileka zabo zesevisi. E-US, isibonelo, kokubili i-AT & T ne-Verizon isetshenziswe imikhiqizo evela kuSierra Wireless ngisho noma ibizwa ngokuthi "AT & T AirCard" ne "Verizon AirCard." I-AirCards isatholakala kubahlinzeki abakhulu njenge-Netgear ne-Sierra Wireless.
I-modem ye-AirCard engenazintambo ifika ngezinhlobo ezintathu ezijwayelekile zefomu, futhi zidinga ichweba elihambisanayo noma isakhiwo se-laptop ukuze isebenze kahle.
- I-PCMCIA I-PC Card iyimodemu ye-modem yangempela yeselula yamakhompyutha.
- I-ExpressCard inikeza ukunyuka okukhulu komkhawulokudonsa ngaphezu kwekhadi le-PCMCIA elithathelwe esikhundleni.
- I- modem ye- USB inikeza ukuxhumeka kweselula kunoma iyiphi ikhompyutha enechweba le-USB.
Amamodemu angenantambo asebenzisa uhlelo olulodwa noma ngaphezulu kwezivumelwano zenethiwekhi yeselula. I-AirCards ye-Late-model ihambisa isivinini se- 3G / 4G LTE esingaba yi-broadband-quality emadolobheni nejubane le-3G ezindaweni eziningi zasemaphandleni.
Ukuhamba kwe-AirCard
I-AirCards isekela amazinga aphezulu kakhulu wedatha kunokuba uxhumano lwe -dial-up . Ngenkathi ama-AirCards amaningi anikezela ku-3.1 Mbps isilinganiso sedatha yokulandwa futhi kufika ku-1.8 Mbps ukulayishwa, imodemu entsha yeselula ye-USB ifinyelela ku-7.2 Mbps phansi kanye no-5.76 Mbps phezulu. Ngisho noma amazinga e-AirCard yedatha ejwayelekile efinyeleleka ekusebenzeni aphansi kunezimpendulo eziqondiswayo, basengaphezu kokudlula kokuxhumeka koxhumano lwe-dial-up.
Ukusetshenziswa kokusebenzisa i-AirCards yokuxhumana kwe-intanethi
I-AirCards ivame ukuhlushwa yi-high latency latency ngezinye izikhathi ngisho nokuphakama kunokuxhumana kokudayela, nakuba ngabe ijubane lokuxhumeka liye lathuthuka, kunjalo nenkinga ye-latency. Ngaphandle kokuthi uxhumano lwe-3G / 4G, lindela ukuzwa ukuvilaphaza nezikhathi zokuphendula kancane lapho ulayisha amapheshana ewebhu ngaphezu kokuxhumana kwe-AirCard. Amageyimu enethiwekhi ngokuvamile awadlaleki kwi-AirCards ngalesi sizathu. Iziningi ze-AirCards azikwazi ukuncintisana namazinga jikelele okusebenza we- DSL noma i-cable broadband internet connection, kodwa ezishayo ziletha isivinini esilingana nabanikezeli bezinsizakalo zabo, okunye kwezinye izimo kuyinhlangano ye-broadband-quality.
