Ndezvipi Zvakawandisa Zvandinoda Kuti Ndiwane VoIP?
Bandwidth inoshandiswa zvakasiyana-siyana nehutano hwekufambisa, kunyange zvazvo zviri pachena kuti haisi zvakafanana. Bandwidth is, chaizvoizvo, mararamiro akasiyana-siyana kuburikidza nedhidhiyo inoparidzirwa. Izvochete zvinyorwa zvinoshandiswa kune redhiyo, TV nekutapudza deta. Ruzhinji bandwidth 'range' zvinoreva kuti mamwe mashoko anotapurirwa panguva imwe chete munguva, uye saizvozvo nokukurumidza kukuru. Kunyangwe tichave tichishandisa mazwi maviri zvisinganzwisisiki pano, technically bandwidth haisi kushamwaridzana nokukurumidza, kunyange zvazvo inoshandiswa zvakasiyana-siyana nevashandisi vakawanda veIndaneti.
Kuyera Bandwidth
Bandwidth inotarwa muHertz (Hz), kana MegaHertz (MHz) nokuti Hertz inowanikwa mumamirioni. Imwe MHz imwe mamiriyoni Hz. Kuwirirana kwekubatanidza (inyanzvi inonzi bit rate) inoyerwa muChilobits kwechipiri (kbps). Inongova chiyero chekuti zvikwereti zvakadini zvinoparidzirwa mune imwe yechipiri. Ndiri kuzoshandisa kbps kana Mbps kuti nditaure nezvekufambisa mberi kubva zvino zvichienda nokuti ndizvo zvinotaurwa nemumwe mutapi webasa paanotaura nezvekukurumidza kwavanopa. Rimwe Mbps imwechete kbps.
Iwe unogona kuva nemafungiro ekuti zvakanaka kana zvakaipa zvakadini kushamwaridzana kwako nokukurumidza uye uye kana kwakakodzera VoIP kuburikidza nekuita svondo rekutsvaga mutsara. Verenga zvakawanda pamusoro pekuongororwa kuno.
Bandwidth Cost
Kune vanhu vakawanda vachishandisa Indaneti sehurukuro yekukurukurirana, bandwidth inowanzove inonyanya kudiwa, nokuti inowanzoitika. Nokuda kwekukurukurirana kwemashoko, zvikwata zvekufamba kwechikwata zvinotonyanya kukosha, sezvo inzwi rwuri rudzi rwemashoko anonyanya kudarika zvinyorwa zvekare.
Izvi zvinoreva kuti kukura kwekufambisa kwakanyanya, zviri nani inzwi raunogona kuwana. Nhasi, kushamwaridzana kwebandaneti ndiyo hurukuro inowanikwa uye inodhura uye inodhura.
Broadband ihutano husingagumi (maawa makumi maviri nemaviri uye nokuda kwehuwandu hwaunoda kushandisa) pane imwe nguva yakakwirira kudarika iyo yekudhinda-56 kbps.
Vakawanda vanopa zvinhu vanopa madiki 512 kbps nhasi, izvo zvakanyanya kukwana kuNVIP kuyanana. Iyi ndiyo mamiriro enyika dzakabudirira uye zvikamu. Kune dzimwe nzvimbo, vamwe vashandisi vasati vadzivirirwa kusvika kuderera kushamwaridzana nokukurumidza pamitengo yakakwirira.
Common Bandwidths
Ngatitarisei kune rimwe divi rakasvibiswa rakabatana nemichina yakakurumbira yekukurukurirana uye teknolojia.
| Technology | Speed | Shandisa muVoIP |
| Dial-Up (modem) | Kusvika ku 56 kbps | Kwete |
| ISDN | Kusvikira 128 kbps | Yakakodzera, nokuda kwebasa rakagadzirirwa uye rakatsaurirwa |
| ADSL | Kusvikira kune dzimwe Mbps | Rimwe remhando dzakanakisisa dzeWAN technologies, asi haritauri kufamba |
| Midziyo isina utsi (semu WiFi, WiMax, GPRS, CDMA) | Kusvikira kune dzimwe Mbps | Mimwe mitambo yakakodzera yakakwana apo dzimwe dzisingakwanisi kure nemhara uye zviratidzo zvehutano. Ndiyo nzira dzekufambisa kune ADSL. |
| LAN (kureva Ethernet ) | Kusvikira kuzviuru zveMa Mbps (Gbps) | Izvo zvakanakisisa, asi zvishoma kune urefu hwemambo dzingave dziri pfupi munguva dzakawanda. |
| Cable | 1 kusvika 6 Mbps | Kukura kwepamusoro asi kumisa kusununguka. Yakakodzera iwe haufaniri kutama. |
Bandwidth uye Apps
VoIP apps pafoni yako yekushandisa inoshandisa bandwidth zvakasiyana. Izvi zvinobva pamakodecs avanoshandisa kuti vadzidzise dhiyabhorosi yekutumira uye pane zvimwe zvekuongorora. Skype, somuenzaniso, iri pakati pemapurogiramu anowanzoitwa VoIP inopedza deta yakawanda kana kufamba kwegwendefa kwemaminetsi ekukurukurirana, sezvo inopa HD izwi.
Saka, apo hutano huri nani, iwe unoda hupamhi hwomukati uye uchishandisa zvakawanda maererano nemamigabytes. Izvi zvakanaka paWiFi, asi iwe unofanira kufungisisa nezvazvo paunoshandisa data yako yefaira. Verenga zvakawanda pamusoro pekushandisa data yefoni.
