Ngingakanani I-Bandwidth Ngidinga Nge-VoIP?
Ukuhamba komkhawulokudonsa kusetshenziselwa ukushintshaniswa ngejubane, nakuba ngokoqobo akufani ncamashi. I-Bandwidth, empeleni, i-frequencies ehlukahlukene lapho kudluliselwa khona idatha. Izimiso ezifanayo ziyasebenza kumsakazo, iTV kanye nokudluliswa kwedatha. Ibanga elikhulu lomkhawulokudonsa lisho ukuthi idatha eyengeziwe idluliselwa ngesikhathi esisodwa ngesikhathi, ngakho-ke ngesivinini esikhulu. Yize sizobe sisebenzisa le mibandela emibili lapha, ngokusemthethweni ukuhamba komkhawulo akuyona isivinini sokuxhumeka, nakuba kusetshenziselwa ukusebenzisana nabasebenzisi abaningi be-inthanethi.
Ilinganisa umkhawulokudonsa
Ububanzi bomkhawulo bubalwa ku-Hertz (Hz), noma i-MegaHertz (MHz) ngoba i-Hertz ibalwa ngezigidi. I-MHz eyodwa i-Hz yezigidi. Isivinini sokuxhumeka (okuthiwa nge-bit rate) silinganiswa ngama-Kilobits ngomzuzwana (kbps). Kuyisilinganiso nje sokuthi zingaki izibhamu ezidluliselwa ngomzuzwana owodwa. Ngizosebenzisa i- kbps noma i-Mbps ukuze ngibheke isivinini sokudlulisela kusukela manje kuze kube manje ngoba yilokho okushiwo wonke umhlinzeki wenkonzo okukhulunywa ngakho lapho ekhuluma ngesivinini abanikezayo. I-One Mbps iyi-kbps eyizinkulungwane.
Ungaba nombono wokuthi kuhle kangakanani noma kubi kangakanani isivinini sakho sokuxhumeka nokuthi ngabe sifanele yini i-VoIP ngokwenza ukuhlolwa kokuxhuma kwi-inthanethi. Funda kabanzi mayelana nokuhlolwa kokuxhumeka lapha.
Izindleko zomkhawulokudonsa
Kubantu abaningi abasebenzisa i-intanethi njengendlela yokuxhumana, ukuphuma komkhawulokudonsa kubonakala kuyimfuneko ebiza kakhulu, ngoba iphindaphinda. Ukuze kukhulunywe ngezwi, izidingo zomkhawulokudonsa zibaluleke kakhulu, ngoba izwi luhlobo lwedatha olwengeziwe kunombhalo ovamile.
Lokhu kusho ukuthi isivinini esikhulu sokuxhuma, ngcono ikhwalithi yezwi ongayithola. Namuhla, ukuxhumeka kwe-broadband kuyinkulumo evamile futhi ishibhile futhi ishibhile.
U-Broadband uxhumano olungenamkhawulo (amahora angu-24 ngosuku futhi ngokuningi ofuna ukuwasebenzisa) ngesivinini esiphezulu kakhulu kunalokhu ku-56 kbps yokudayela.
Abahlinzeki abaningi banikeza okungenani 512 kbps namuhla, okuyinto enkulu ngokwanele yokuxhumana VoIP. Yilokho okwenziwe amazwe namazwe athuthukile. Kwezinye izindawo, abanye abasebenzisi namanje bavinjelwe ngesivinini esiphansi sokuxhuma ngamanani aphezulu.
Ama-Bandwidths ajwayelekile
Ake sibuke umkhawulokudonsa ovamile ohambisana namadivaysi okuxhumana athandwayo nobuchwepheshe.
| Ubuchwepheshe | Isivinini | Sebenzisa ku-VoIP |
| I-Dial-Up (i-modem) | Kuze ku-56 kbps | Akufanelekile |
| I-ISDN | Kuze kube yi-128 kbps | Kuyafaneleka, ngensizakalo ehleliwe nezinikele |
| I-ADSL | Kuze ku-Mbps eziningana | Enye yezobuchwepheshe obungcono kakhulu ze- WAN , kodwa ayinikeli ukuhamba |
| Ubuchwepheshe obungenantambo (isib. I-WiFi, i-WiMax, i-GPRS, i-CDMA) | Kuze ku-Mbps eziningana | Okunye ubuchwepheshe bufanelekile kuyilapho ezinye zilinganiselwe ngezinga lebanga kanye nesignali. Ziyindlela ehamba phambili ye-ADSL. |
| I-LAN (isib. Ethernet ) | Kuze kube yizinkulungwane zeMbps (Gbps) | Okuhle kakhulu, kodwa kunomkhawulo wocingo lungaba lula ezimweni eziningi. |
| Ikhebula | 1 kuya ku-6 Mbps | Isivinini esiphezulu kodwa sikhawuleka ukuhamba. Ingabe kufanelekile akudingeki ukuba uhambe. |
I-Bandwidth nezinhlelo zokusebenza
Izinhlelo ze-VoIP kudivayisi yakho yeselula zidla umkhawulokudonsa ngokuhlukile. Lokhu kusekelwe kuma-codec abasebenzisa ukufaka idatha yokudlulisela kanye nezinye izinto eziphathelene nobuchwepheshe. I-Skype, isibonelo, iphakathi kwezinhlelo zokusebenza ezivamile ze-VoIP ezidla idatha eyengeziwe noma umkhawulokudonsa ngomzuzu wokuxhumana, njengoba inikeza i-HD izwi.
Ngakho-ke, ngenkathi izinga lihle kangcono, uzodinga umkhawulokudonsa ophezulu futhi usebenzise okuningi ngokwemigomo yama-megabytes. Lokhu kuhle ku-WiFi, kodwa kufanele ukhumbule ngakho uma usebenzisa idatha yakho yeselula. Funda kabanzi mayelana nokusetshenziswa kwedatha yeselula.
