Megabytes Yangu Indaneti Inodanwa Kudya
Pakati pezvinhu zvinoshandiswa pakushandisa data paInternet zvinoratidza kuti vazhinji, kana kwete vose, havasi kusanganisira kushandiswa kwedhizwi yeVoIP mukufungisisa kwezvinhu zvinoshandisa dhidhiro muurongwa hwe data . Kushandisa kwedhiyo yeVoIP yakawanda yei kilobytes uye megabytes yaunoshandisa mudhora rako rekushandisa kwekutaura kwezwi. Vanhu vazhinji havashandisi purogiramu yavo yekufambisa data yekutaurirana kwemashoko , uye vanorasikirwa zvikuru. Kuita inzwi kunoshevedza foni yako pamusoro peurongwa hwekuita kwako hunoita kuti iwe uchengetedze mari yakawanda pahutano; ona kuti zvikonzero nei vanhu vachishandisa VoIP . Kunze kwekuti, kushandisa deta yako maminitsi kuita inzwi rekufema kune zvakakosha zvakanyanya kudarika kubudiswa kwevhidhiyo kana kukanda MP3, somuenzaniso. Saka, kana VoIP chinhu chimwe chekushandisa kwedhare yako, hezvino iwe unofungidzira bandwidth iwe unoda kuti inzwi ridane mwedzi. Iwe unogona kuwedzera iyo kukosha kune izvo yako yekushandisa data yekushandisa inoratidza .
Maminitsi Mashoma Sei?
Iva nekufungidzira kwehuwandu hwekutumira maminitsi aunoda. Itai zvose zviri kubuda uye kupinda mafonero. Ichi hachisi basa rakanyanya. Imwe nzira yekupfuura nayo iyo ndeyekutora mwedzi wekuenzanisa yekucherechedza pasi mafonero awakagadzira uye akagamuchira uye nguva yavo. Kana iwe une smartphone , unoponeswa kubva pakushandisa pepa uye pepa. Uyezve, unogona kuva nemapurogiramu anoita basa kwauri kumashure.
Iwe unoda kuparadzanisa pakati pemhando dzekufonera kwaunoita. Kune nhare dzinodiwa kuburikidza neGMM. Iwe uchasarudza VoIP nokuda kwemafoni akadai semakambani enyika , vatinhi vari kushandisa imwechete sevhisi yeViIP sezvauri (izvi zvinoshevedzwa zviri pachena) kana kudanidzira kusingabhadharwi munzvimbo inoenderana nehumwe hutano hweVoIP (semuona Gmail inoshanya ).
Nhamba yeDhiyabhorosi Yakapedzwa
Kuti uzive kuti ndangani maitiro ekukurukurirana kwezwi anotora, unofanirwa kuziva kuti codec yako inoshanda yeVoIP iripi . A codec iyi injini inoshandura iyo inoshandura inzwi rako (analog) muchidimbu cheku digital, richibvisa nguva dzinyararire (iyo inosvika hafu yezvokukurukurirana zvose), uye kuita zvimwe zvinhu kuti ipe dheji mutoro sechiedza sezvinobvira. Verenga zvakawanda pamusoro pe codecs ikoko.
Pano pane zviyero zvinoshandiswa pakushandiswa kwedhesi yekodecs dzakajairika dzinoshandiswa kuVoIP:
G.711 - 87Kbps
G.729 - 32 Kbps
G.723.1 - 22 Kbps
G.723.1 - 21 Kbps
G.726 - 55 Kbps
G.726 - 47 Kbps
G.728 - 32 Kbps
Aya maitiro achakupa nhau yekuverenga. Somuenzaniso, kweminiti imwe chete yekutaura ne c.7ec C.729, tichaita zvinotevera:
G.729 inotora 32 kilobiti pamusi wechipiri,
iyo iri makirogiramu 1920 (60 x 32) muminiti imwe chete,
iyo inosvika 240 kilobytes (KB) paminiti (1 byte is 8 bits)
Iye zvino izvi ndezvekuti data iende. Inbound data (iyo inofanirwawo) inotora mutoro mumwe chete, saka tinowedzera chiyero kusvika 480 KB.
Pakupedzisira, tinogona kukomberedza kukosha kusvika ku 0.5 MB paminiti yekukurukurirana.
Iko G.729 codec imwe yezwi rakanakisisa rinoita codecs uye dzakawanda zvakanaka maSeIP services dzinoshandisa iyo.
Iwe unofanirwa kuona kuti pane zvakawanda zvigadziriswe, izvo zvinenge zvishandiso mune zvezvisikwa, zvinokanganisa maitiro ari pamusoro apa. Pakati pavo ndeyero (payload) yezwi mapaketi, nguva dzavanotumirwa uye nhamba yepakiti inotumirwa mune imwe yechipiri (kazhinji). Kune vazhinji vedu, zvatinoda ndeyekufungidzira kwekufungidzira. Saka, isu tinogona kubvisa nyore nyore kunyora. Uyewo, hatigoni kuziva kuti codec iri kushandiswa. Ini pachedu, ndinotora mavhareji yekbps 50 kodec chero ipi zvayo. Izvi zvinopa (mushure mekuverenga nekufungidzirwa) 0.75 MB paminiti yekukurukurirana.
Saka, kana ukaronga awa yekukurukurirana, inenge iine 45 MB.
