Ukuthola nokuhlala kuxhunyiwe ngamanethiwekhi weselula
Amanethiwekhi asekhaya asebenzisa amamodemu ukuxhuma kwi-inthanethi. Isevisi ngayinye ye-intanethi isebenzisa uhlobo lwayo lwe-modem. Ngokwesibonelo,
- I-dial-up ne- DSL imodemu ixhuma kumakhalekhukhwini wefoni
- I-modems yekhebula ixhuma kulayini lwekhebula le-TV yekhaya
- I-modem ye- fiber optic ixhunyaniswa nezintambo ze-fiber optic ezifakiwe ekhaya
- imodemu engenantambo
Yini Amamodeli Weselula?
I-modems yeselula ingenye yalezi ezinye izinhlobo ze-modems yenethiwekhi. Amamodeli weselula ayihlobo lomsindo ongenazintambo ovumela amakhompyutha namanye amadivayisi ukufinyeleleka kwe-intanethi. Esikhundleni sokuxhuma kwenye ikhebula ekhonza njengepayipi yenethiwekhi, imodemu yamaselula ixhumana ngezixhumanisi ezingenantambo kwi-Inthanethi ngemibhoshongo yocingo. Ukusebenzisa i- modem yeseli inikeza izinzuzo eziningana ngaphezu kwezinye izinhlobo ze-modems:
- Isevisi yeselula yedijithali iyashesha kunokuba i-intanethi ye-dial-up
- Ukufinyeleleka kwe-intanethi kungasetshenziswa ngenkathi kuhamba futhi kunoma iyiphi indawo isignali yeseli iyatholakala
- Kweminye, isevisi yeseli ingase ishibhile kunezinye izinhlobo zesevisi ye-intanethi ye- broadband
Izinhlobo zeModemu yeselula
Izinhlobo ezintathu eziyinhloko zamamodemu ezinamaselula zikhona ekuxhumaneni kwenethiwekhi :
- amaselula - usebenzisa amafoni njengemodemu ukuvumela ukufinyeleleka kwi-intanethi kumakhompyutha, ngezinye izikhathi kuthiwa yi- tethering
- amakhadi eselula - ama- adapter enethiwekhi ephathekayo afaka ama-computer, ngezinye izikhathi abizwa ngokuthi ama- aircards
- ama-router eselula - ama- routers wenethiwekhi ephathekayo aqukethe imodemu yeselula eyakhiwe
Ukusetha Amafoni Omakhalekhukhwini njengeModemu Engenantambo
Izinyathelo ezithize zokusetha ukuthambisa zixhomeke kumodeli weselula ezisetshenziswayo, kodwa inqubo efanayo efanayo isebenza kuwo wonke amacala:
- setha ifoni ye-Inthanethi isevisi
- xhuma ifoni kwikhompyutha
- faka isofthiwe yokuphatha ucingo olufanele kwikhompyutha
Abahlinzeki bamaseli bathengisa izinhlelo zesevisi (ngokuvamile ezibizwa ngokuthi izinhlelo zamadatha ) ezivumela ifoni ye-digital ukuba isebenze njengemodemu ye-inthanethi engenawaya. Uma ubhalisa kuhlelo lwedatha, qiniseka ukuthi isevisi ivumela ukusetshenziswa okungenamkhawulo noma unomkhawulo ophezulu we- bandwidth ukugwema amacala amaningi. Ifoni ayikwazi ukusebenza njengemodemu ngaphandle kokuthi uhlelo olusebenzayo lwenkonzo lukhona.
Amafoni angakwazi ukuxhuma kwamanye amadivaysi aseduzane esebenzisa ikhebula le- USB noma nge- Bluetooth wireless. Nakuba ukuxhumeka kwe-Bluetooth kuhamba kancane kune-USB, abaningi bakhetha ukuxhumana okungenazintambo uma ikhompyutha yabo isisekela (njengoba cishe wonke amadivayisi eselula enza). Zombili izinhlobo zinikeza ukudonsa okwanele kwezixhumanisi eziningi zeselula.
Izinkampani ezinikeza isevisi yeselula nazo zinikeza isofthiwe yamahhala edingekayo ukusetha amafoni njengamamodemu angenawaya nokuphatha ukuxhumana kwabo. Mane nje ufake isofthiwe kwikhompyutha ezosetshenziselwa ukulungiswa ngokulandela imiyalelo yomhlinzeki.
Ukusetha Amakhadi E-Cellular nama-Routers
Amakhadi weselula nama-router asebenza ngendlela efanayo nezinye izinhlobo zendabuko ze- adapters yenethiwekhi kanye namabhurogi wokubambisana . Ama-aircards ngokuvamile axhuma kwi- USB port (noma ngezinye izikhathi nge- PCMCIA ), kuyilapho ama-routers weselula angamukela noma uxhumano lwe-Ethernet noma lwe-Wi-Fi. Abakhiqizi abahlukahlukene bathengisa la makhadi kanye nama-routers.
Ukulinganiselwa kwe-Cell Modem Networking
Nakuba ukuhamba kwabo kwenethiwekhi kuye kwanda kakhulu eminyakeni eminingana eyedlule, ukuxhumeka kwamaseli kwi-Inthanethi ngokuvamile kunikela ngamazinga okuhamba kancane kwedatha kunezinye izinhlobo ze-intanethi ye-broadband, ngezinye izikhathi ngisho nangaphansi kwe-1 Mbps . Uma uxhunyiwe, umakhalekhukhwini awukwazi ukuthola izingcingo zezwi.
Abahlinzeki be-intanethi bafaka imingcele eqondile ekusetshenzisweni kwedatha kwansuku zonke noma ngenyanga yesevisi yabo yeselula. Ukudlulela kulezi zinhlawulo ze-bandwidth imiphumela yemali ephezulu futhi ngezinye izikhathi ngisho nokuqedwa kwenkonzo.
