Amadivaysi edijithali e-aka "ama-smartphones" ayasebenza amadivaysi eklayenti e-Inthanethi Uma ixhumeke kukhompyutheni yakho ngokufanele, ingahle isebenze njengemodemu yenethiwekhi evamile. Ukusebenzisa ifoni yakho njengemodemu inikeza indlela yokuthola ukuxhumeka kwe-intanethi ephathekayo uma zonke ezinye izinketho ezinjengezindawo zokuhlala ze-Wi-Fi zehluleka. Ngeshwa, ukusebenza kwalolu xhumano lwenethiwekhi yeselula akumele luhlangabezane nezidingo zomuntu.
Isilinganiso sokudluliswa kwedatha yenethiwekhi enkulu esekelwe yi-modem yeselula ifana kuye ngokuthi izinga lokuxhumana lisevisi yakho yefoni isekela kanjani.
Ukusebenza ku-Generation Generation of Cellular Technology
Ubuchwepheshe benethiwekhi yeselula yanamuhla buwela ngaphansi "3G", "3.5G" noma "4G". Lokhu kufaka phakathi i- LTE , i- HSPA , EV-DO , ne- EDGE . Ubuchwepheshe be-3G buhlinzeka cishe phakathi kuka-0.5 Mbps no-4 Mbps ukulandwa. I-3.5G ne-4G inikela ku-10 Mbps (futhi ngezinye izikhathi ngisho nangaphezulu) kokulandwayo.
Ngokuphambene, ubuchwepheshe bamaseli asebekhulile (okusheshayo aphelelwe yisikhathi ezingxenyeni ezithuthukisiwe zomhlaba) njenge-GPRS (ngokuvamile ebizwa ngokuthi "2.5G"), i-CDMA ne-GSM inikeza ngesivinini esincane esiphansi kwe-100 Kbps noma ephansi, efana nokusebenza kwe-analog dial -modemu ye- intanethi.
Ukusebenza (kanye nekhwalithi) yokuxhumeka kwamaseli kuyahluka kakhulu kunabo bonke abahlinzeki bezinsizakalo, izindawo zendawo, nokulayisha (inombolo yabhalisile abakhuthele) endaweni ethile. Ngenxa yalezi zizathu, ukuvinjelwa kwenethiwekhi noma isilinganiso se-peak ngokuvamile akusebenzi.
Ukusebenza kwe-Theory vs. Actual Cell Modem
Njengezindinganiso eziningi zenethiwekhi, abasebenzisi be-modems yeselula akufanele balindelwe ukufezekisa lokhu okuphezulu kwemfundiso ekusebenzeni. I- bandwidth yangempela oyoyithokozela incike ezintweni eziningana:
- Ikhwalithi yesignali engenawaya yefoni (ngokuvamile, ibanga elisuka esitokisini esiseduze)
- Inethiwekhi ye-network yokuncintisana kwinethiwekhi yomnikezeli weselula
- Inguqulo yenqubo yokuxhumana yenethiwekhi eqashwe umhlinzeki, kanye nanoma yikuphi ukulinganiselwa kwezobuchwepheshe noma izandiso abazisebenzayo
- Ukuxuba kwethrafikhi engezansi futhi engezansi oyenzayo (imodemu yefoni yeselula isekela umkhawulokudonsa ongaphansi kokulayishwa kunokulandwa)
Futhi, cabanga ukuthi "ijubane" lanoma yikuphi inethiwekhi akuxhomeke kuphela kumthamo womkhawulokudonsa osekelwayo kodwa nakulo latency. I-modem yocingo ihlushwa ukukhanya okuphezulu kakhulu kunikezwe uhlobo lokuxhumana kwayo okuvulekile. Uma usebenzisa ifoni yakho njengemodemu, kufanele ulindele ukubona ukulibazisa okulukhuni nokudlulela kokudluliswa kwedatha, okunciphisa isivinini esikubonayo sokuxhumeka kwakho nakakhulu.
