Ingakanani i-bandwidth endiyidingayo ngeVoIP?
I-Bandwidth isetyenziswa ngokuthe tye ngokukhawuleza kwintsebenziswano, nangona ngokobuchwephesha ayifani ngokufanayo. I-Bandwidth, e neneni, uluhlu lwee-frequencies apho idatha idluliselwa khona. Imigaqo efanayo ifaka kwi-radio, iTV kunye nokuhanjiswa kwedatha. Uluhlu olukhulu lwamanqwanqwa oluthile lithetha ukuba idatha eninzi idluliselwa ngexesha elinye ngexesha, kwaye ngaloo ndlela isantya esikhulu. Nangona siza kusebenzisa le mibini emibini apha, apha i-bandwidth ayikho isantya soxhumano, nangona asetyenziswe ngokubanzi ngabasebenzisi abaninzi be-intanethi.
Ukulinganisa iBwindwidth
I-Bandwidth ilinganiswa ku-Hertz (Hz), okanye i-MegaHertz (MHz) kuba i-Hertz ibalwa kwizigidi. I-MHz enye i-Hz yezigidi. Isantya soxhumano (ngokubizwa ngokuba yi-bit rate rate) sisilinganiswa kwiiKlobits ngesibini (kbps). Kuphela nje umlinganiselo weendlela ezininzi ezithengiswa kwisibini. Ndiya kusebenzisa i- kbps okanye i-Mbps ukubhekisela kwisantya sokuhambisa ukususela ngoku ngoku, kuba nguwuphi na umnikezeli wesevisi othetha ngayo xa ebhekisela kwisantya abanikela ngazo. I- Mbps enye iwaka kbps.
Unokuba nombono wendlela enhle okanye engalunganga ngayo isantya sakho soxhumo kunye nokuba ingafanelekile kwiVoIP ngokuqhuba iimvavanyo zoxhumo kwi-intanethi. Funda ngokubanzi kwiimvavanyo zokhuseleko apha.
Iindleko zeBtwidth
Kuba abaninzi abantu basebenzisa i-intanethi njengendlela yokunxibelelana, umda womda wokuba umda wenziwa njengowona mfuneko ebiza kakhulu, kuba iphindaphinda. Ukunxibelelana ngezwi, iimfuno zomda wokubaluleka zibaluleke kakhulu, kuba ilizwi luhlobo lwedatha enobungakanani kunombhalo oqhelekileyo.
Oku kuthetha ukuba i-speed speed connection, ngcono izinga lezwi onokufumana. Namhlanje, uxhulumaniso lwebhanki luyintetho eqhelekileyo kwaye ifikeleleka kwaye ishibhile.
I-Broadband inxibelelwano elingenamkhawulo (iiyure ezingama-24 ngosuku kunye nangoko ufuna ukuzisebenzisa) ngesivinini esiphezulu kunokuba se-56 kbps yokudayela.
Uninzi lwababoneleli banike ubuncinane ubuncinane be-512 kbps namhlanje, eninzi ngokwaneleyo kwintetho ye-VoIP. Yiyo imeko kumazwe athuthukileyo kunye nemimandla. Kwezinye iindawo, abanye abasebenzisi basenqatshelwe kwixesha eliphantsi lokuxhuma kwixabiso eliphezulu.
Bandwidths eziqhelekileyo
Makhe sijonge kwi-bandwidth eqhelekileyo enxulumene nezixhobo zonxibelelwano ezidumile kunye nobuchwepheshe.
| Te knoloji | Ukukhawuleza | Sebenzisa kwiVoIP |
| Ukudayela-up (i-modem) | Ukufikelela kuma-56 kbps | Akufanelekile |
| ISDN | Ukufika kwi 128 kbps | Efanelekayo, kwinkonzo ehleliweyo neyekezelweyo |
| ADSL | Ukufikelela kwiiMbps eziliqela | Enye yezobuchwephesha ze- WAN , kodwa ayiniki ukuhamba |
| Ubuchwepheshe obungenazintambo (umz. WiFi, WiMax, GPRS, CDMA) | Ukufikelela kwiiMbps eziliqela | Olunye ubuchwephesha lufanelekile ngelixa ezinye zilinganiselwe umgama kunye nomgangatho wesigxina. Ziyindlela ehambayo ye-ADSL. |
| LAN (umz. Ethernet ) | Ukufikelela kumawaka e-Mbps (Gbps) | Eyona nto ibhetele, kodwa iyancipha ubude beencingo ezinokuba zifutshane kwiimeko ezininzi. |
| Ikhefu | 1 ukuya ku-6 Mbps | Isantya esiphezulu kodwa sikhawuleza ukuhamba. Ngaba kufanelekile ukuba akufanele uhambe. |
Bandwidth kunye neNkqubo
Iifayile zeVoIP kwisistim sakho sefowuni zidla umgama wendlela eyahlukileyo. Oku kusekelwe kwiikodecs ezizisebenzisayo ukudibanisa idatha yokudluliselwa kunye nezinye izinto zobugcisa. I-Skype, ngokomzekelo, iphakathi kweenkqubo eziqhelekileyo zeVoIP ezidla idatha engaphezulu okanye umda womda ngomzuzu woqhagamshelwano, njengoko unikeza ilizwi le-HD.
Ngoko, ngelixa umgangatho ungcono kakhulu, uya kufuna i-bandwidth ephezulu kwaye uchithe ngaphezulu ngokwemegabyte. Oku kuhle kwi-WiFi, kodwa kufuneka uyikhumbule xa usebenzisa idatha yakho yeselula. Funda kabanzi malunga nokusetyenziswa kwedatha yeselula.
