Izantya zokuphumelela kwi-Broadband ziyahluka ngamazwe
Igama elithi "broadband" lithetha ngokubhekiselele kunoma yiluphi udidi lweendlela zokudlulisela isiginci-mhlawumbi ngumoya okanye engenazintambo-ezithwala iintlobo ezimbini okanye ezahlukeneyo zedatha kwimida ehlukeneyo. Ukusetyenziswa okuthandwayo, kubhekisela kunxibelelwano lwe-intanethi.
Iinkcazo ze-Broadband
Njengoko ukuxhunywa kwenethiwekhi endala yokudibanisa kwi-intanethi kwaqala ukutshintshwa kwindlela entsha, iindlela ezisezantsi ezongezelelekileyo, zonke iinkqubo zobuchwepheshe obutsha ngokuqhelekileyo zathengiswa njenge "intanethi ye-intanethi." Amacandelo karhulumente kunye namashishini azame ukubeka iinkcazo ezisemthethweni zento ekwahlula iinkonzo zesebhanti kwi-intanethi ebanzi, ngokukodwa ngokusekelwe kwizinga eliphezulu zedata abaxhasayo. Ezi nkcazo ziye zahluka ngexesha kunye nelizwe. Umzekelo:
- KwiiPhilippines, ukukhuphela amaxabiso e-256 Kbps afanelekileyo njenge-broadband (ngo-2016)
- E-Indiya, umgca wesivinini esivumelekileyo esisemthethweni ukuphakanyiswa ukusuka kwi-256 Kbps ukuya ku-512 Kbps ukulandwa ngo-2014.
- E-US, i-Federal Communications Commission yaphakamisa umyinge wezinga lokusasazwa ngo-2015 ukusuka kwi-4 Mbps ukuya kuma-25 Mbps ukulandwa kunye ne-1 Mbps ukuya kuma-3 Mbps ukulayisha. Ekuqaleni, emva kwe-1999, iFCC isetyenzisile umda wayo omkhulu kwi-200 Kbps ukulandwa.
Iintlobo zeeTeknoloji zeeNkcazo zoBanzi
Phakathi kobuchwephesha bokufikelela kwi-intanethi ngokuqhelekileyo kubalwa njengebandatshana ebanzi:
- Umnxeba wokuBhalisa weDialog (i-DSL) - inkonzo ye-Intanethi edibanisa izithuthi zezwi kunye needatha ezihlukeneyo phezu komgca omnye wefowuni. Kwi-DSL, i-traffic traffic izalisekisa ukuphela komgca we-frequency spectrum kunye nedatha igcwalisa ukuphela okuphezulu.
- I-modem yecala - Inkonzo ye-intanethi idibanisa idatha ephakamileyo ngokukhawuleza ngeempawu zevidiyo ezinikezwa phezu kwemigca yeTV
- Intambo ebanzi ye-Intanethi - Iinkcukacha ze-intanethi ezixhunywe nge-smartphones nakwamanye amadivaysi eselula kumanethiwekhi eselula
- I-Fiber Internet (i-FTTH) kunye nezintambo ezingenasiphelo ze-broadband - iintlobo zeenkonzo ze-intanethi ezifanelekileyo njenge-intanethi ye-intanethi phantsi kwengcaciso eyaziwayo nangona lobuchwephesha bephethe kuphela uhlobo olulodwa lwezithuthi zedatha ezixhomekeke kwi-intanethi.
Intanethi yee-Broadband zasekhaya yenza ukwabelana nokufikelela kwi-intanethi ye-intanethi ngokubanzi ngeteknoloji zentengiso zendawo ezifana ne- Wi-Fi ne- Ethernet . Nangona zombini zombini isebenza ngokukhawuleza, akukho nxaxheba kubonwa njengebandatshana.
Imiba ene-Broadband
Abantu abahlala kwiindawo ezincinci okanye abangakhuselekanga badla ukungabikho kokufikelela kwiinkonzo ze-intanethi kwi-broadband njengoko ababoneleli banesiseko esincinci sezemali kwiindawo zenkonzo nabancinci abathengi. Iinkonzo ezibizwa ngokuba yi-municipal broadband networks ezinika inkonzo ye-intanethi exhaswa nguRhulumente kubahlali bakhelwe kwezinye iindawo, kodwa ezi zifikeleleke kwaye zibikwe ukuba zenze ukuba kubekho ukuxhatshazwa ngamashishini anikezela ngeenkonzo ezizimeleyo.
Ukwakha amanethiwekhi omnatha wokufikelela kwi-intanethi ye-intanethi ingaba yindleko ngenxa yeziseko ezibanzi kunye nomgaqo-shishino ochaphazelekayo. Iindleko zophuhliso lweziseko eziphezulu zikwenza kube nzima kubaboneleli benkonzo ukunciphisa amaxabiso okubhaliselwa kwabo kwaye banikeze ngokuqinisekileyo abathengi ukukhawuleza kokuxhamla abayifunayo. Kwimeko embi kakhulu, abasebenzisi banokuhlawuliswa imali eyongezelelweyo yemali yokudlula imali yabo yesibonelelo sesicwangciso seenyanga okanye ukuba inkonzo yabo ivalwe okwesikhashana.
