Digital cell phone aka "smartphones" inobatsira maIndaneti makambani ekushandisa. Kana yakabatana nekombiyuta yako zvakanaka, inogonawo kushanda se-general-purpose network network . Kushandisa foni yako se modem inopa nzira yekuita kuti Indaneti ive nehutano kana dzimwe dzose zvingaita seHi-Fi hotspots zvinokundikana. Zvinosuruvarisa, kushanda kweiyo mafaira ekubatana kwemasero hakugoni kusangana nezvido zvemunhu.
Inoretical maximum network data transfer rate inotsigirwa neserurafomu modem yakasiyana zvichienderana nehutano hwehutano inoshandiswa nefoni yako.
Maitiro Ase Zvizvarwa zveCellar Technology
Mazuva ano cell cell network technologies inowira pasi pe "3G", "3.5G" kana "4G" zvinyorwa. Izvi zvinosanganisira LTE , HSPA , EV-DO , uye EDGE . 3G teknolojia inopa zvakanyanya pakati pe 0.5 Mbps uye 4 Mbps zvekutsvaga. 3.5G uye 4G inopa kusvika 10 Mbps (uye dzimwe nguva kunyange yakakwirira) zvekutsvaga.
Kusiyana neizvi, kare kare magetsi ekutsvaga (kukurumidza kushaya kushanda mune dzimwe nzvimbo dzakabudirira yenyika) seGPRS (inowanzoonekwa se "2.5G"), CDMA ne GSM inopa kukurumidza kuderera nepamusoro pe 100 Kbps kana pasi, yakafanana nekushanda kweiyo inonzi analog dial -up Internet modem.
Kuitwa (uyewo nehutano) chekubatanidza kwemajeri kunowirirana zvikuru kune vanopa mazano, nzvimbo dzenharaunda, uye mutoro (nhamba yevanyori vanoshanda) pane imwe nzvimbo. Pamusana pezvikonzero izvi, chiyero kana kuti peak network inowanzosawanzoshanda.
Theorytical vs. Actual Cell Modem Performance
Sezvo nevakawanda mitambo yekutengesa, vanoshandisa foni modems havafaniri kutarisira kuti vawane izvi zvidzidzo zvepamusoro pakuita. Icho chikwata chaicho chaunofara chinoenderana nezvimwe zvinhu zvinoitika:
- Unhu hwemutsara usina foni yefoni (kazhinji, kure nechokuita nesero rinoswedera pedyo)
- Kupikisa network traffic pa cell phone provider network
- Shanduro yehutano yekukurukurirana protocol yakashandiswa nemupiki, pamwe chete nehupi hwemakemikari kana zvikwidziro zvavanoshandisa
- Kusanganiswa kwepamusoro uye kumanuka kwenzira iwe unogadzira (cell phone modems inotsigira kuderera kwechikwata chekudarika kupfuura kuitora)
Uyewo, funga kuti "kukurumidza" kwekwenyese mitambo hakungoratidzi chete pamutengo wechipupuriro chakatsigirwa asiwo pane latency. Semufoni modem inotarisana ne-high latency inowanikwa maitiro ekutsvaga kwayo. Paunenge uchishandisa foni yako se modem, unofanirwa kutarisira kuona kusviba kunonoka uye kuputika kwekufambisa kwemashoko, izvo zvinoderedza kuonekwa kwekufambisa kwako kunyanya.
