Megabytes Mafoni Anga pa intaneti Amaitana Kudya
Zozungulira pazomwe amagwiritsira ntchito deta pa intaneti zikuwonetsa kuti ambiri, ngati si onsewo, samaphatikizapo ntchito ya data ya VoIP pokambirana zomwe zimagwiritsa ntchito deta mu ndondomeko ya deta . Kugwiritsa ntchito data kwa VoIP ndi kuchuluka kwa kilobytes ndi megabytes omwe mumagwiritsa ntchito ndondomeko yanu ya deta yolankhulirana. Anthu ambiri samagwiritsa ntchito pulani yawo ya deta yolankhulirana , ndipo amataya zambiri. Kupanga ma telefoni pa foni yanu pa pulani yanu ya deta kumakupatsani kusunga ndalama zambiri pa mauthenga; onani chifukwa chake anthu amagwiritsa ntchito VoIP . Kuphatikiza apo, kugwiritsa ntchito deta yanu deta kuti muyimbire mafoni ndizofunikira kwambiri kuposa kujambula kanema kapena kukopera ma MP3, mwachitsanzo. Kotero, ngati VoIP ndi chinthu pamagwiritsidwe ntchito anu apamwamba , apa ndi momwe mumaganizira kuti zingatheke bwanji kuti mumve mawu omwe mumakhala nawo mwezi. Mutha kuwonjezera phindu pazomwe makina anu ogwiritsira ntchito akuwonetsera .
Ndi Maminiti Angati?
Khalani ndi chiwerengero cha kuchuluka kwa maitanidwe omwe mukufuna. Phatikizani maulendo awiri omwe akubwera komanso omwe akubwera. Izi si ntchito yophweka. Njira imodzi yothetsera vutoli ndikutengera chitsanzo cha mwezi kuti muzindikire mayina omwe munapanga ndi kulandira ndi nthawi yawo. Ngati muli ndi foni yamakono , mumasungidwa kuchoka pamakina ndi pepala. Ndiponso, mungathe kukhala ndi mapulogalamu omwe amakupangirani ntchito kumbuyo.
Mudzafuna kusiyanitsa pakati pa mitundu yomwe mumaitanira. Pali mayina omwe amayenera kudutsa mu GSM. Mudzasankha VoIP pa mayitanidwe monga maitanidwe apadziko lonse , othandizira omwe akugwiritsa ntchito utumiki womwewo wa VoIP monga inu (maitanidwewo ndi omasuka) kapena maitanidwe omwe ali omasuka kumaloko kudzera mu utumiki wa VoIP (mwachitsanzo, onani Gmail kuyitana ).
Chiwerengero cha Zolemba Zatha
Kuti mudziwe momwe angayambitsire kuyankhulana kwa mauthenga, muyenera kudziwa codec yomwe ntchito yanu ya VoIP ikugwiritsira ntchito. Kodec ndi injini yothandizira yomwe imasintha mawu anu (analog) kukhala deta ya digito, kuchotsa nthawi yopanda malire (zomwe zimaphatikizapo theka la zokambirana zonse), ndi kuchita zina kuti zipangitse deta kukhala yosavuta. Werengani zambiri pa codecs apo.
Pano pali mawerengedwe owerengera a dodecs omwe amagwiritsidwa ntchito pa VoIP:
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
Mfundo izi zidzakupatsani inu ntchito yowerengera. Mwachitsanzo, kwa mphindi imodzi yokambirana ndi codec ya G.729, tidzachita izi:
G.729 imatenga makilogalamu 32 pamphindi,
yomwe ndi makilogalamu 1920 (60 x 32) mu mphindi imodzi,
yomwe imakhala ndi kilobytesiti 240 (KB) pa mphindi (1 byte ndi 8 bits)
Tsopano ndizo chabe kuti deta ikupita. Deta yowonjezera (yomwe imawerengeranso) imatenga katundu womwewo, kotero ife timachiwirikiza chiwerengero ku 480 KB.
Pomalizira, tikhoza kuyendetsa mtengo ku 0.5 MB pa mphindi yokambirana.
Codec ya G.729 ndi imodzi mwa mawu abwino kwambiri opanga ma voods ndipo mautumiki ambiri abwino a VoIP amagwiritsa ntchito.
Muyenera kuzindikira kuti pali magawo ambiri, zomwe ziri zowonjezera zamaganizo, zomwe zimakhudza zomwe zili pamwambapa. Zina mwazo ndizokula (kulipira) kwa mapepala amvekedwe, nthawi yomwe amatumizidwa ndi chiwerengero cha mapaketi omwe amatumizidwa mumphindi imodzi (mafupipafupi). Kwa ambiri a ife, chomwe tikufuna ndi chiwerengero cha kulingalira. Kotero, tingathe kuthetsa mosavuta kulondola. Ndiponso, sitingadziwe kuti codec ikugwiritsidwa ntchito. Mwini, ndimatenga mtengo wa 50 kbps kwa codec iliyonse. Izi zimapereka (pambuyo mawerengedwe ndi kuyerekezera) 0.75 MB pa mphindi yokambirana.
Kotero, ngati mukukonzekera ola la zokambirana, lidzakhala pafupifupi 45 MB.
