Loaʻa iaʻu ke kuʻiʻana i ka VoIP?
ʻO kekahi o nā kumu nui e hāʻawi iā PSTN i kahi haʻawina liʻiliʻi ma luna o VoIP, he leo leo, aʻo kekahi o nā kumu nui e pili ana i ka maikaʻi o ka leo ma VoIP. No ka nānā ikiʻana i ka bandwidth a me nāʻano pilina, e heluhelu i kēiaʻatikala . Maʻaneʻi, ho'āʻo mākou e noʻonoʻo, no kekahi hihia kūpono, inā paha e loaʻa ka bandwīwī i ka bandwīwī i makemakeʻia.
He mea nui loa kēia nīnau no ka loaʻaʻana o ke kūlana maikaʻi maikaʻi, akā, he mea nui no ka poʻe e hoʻohana ana i nā hoʻolālāʻikepili pūnaewele. E makemake lākou eʻike i ka nui o kā lākouʻikepili leo VoIP.
Ma keʻano maʻamau, 90 kbps i lawa no ka maikaʻi VoIP (inā,ʻo ia, heʻano maikaʻi nā mea'ē aʻe ). Akā, he mea paʻakikī kēia i nā wahi kahi i uku nuiʻia ai ka bandwidth, aiʻole i nā'ōpili pūnaewele iʻole e māhele likeʻia ka bandwidth i waena o nā mea hoʻohana.
Inā he kanaka nohoʻoe, e ho'āʻo e hōʻalo i nā kikowaena 56 kbps no VoIP. ʻOiai e hana ana, e hāʻawi ana iāʻoe i ka hopena VoIP maikaʻiʻole. ʻO ka bet maikaʻiʻo ia ka pili DSL. ʻOiaiʻo ia ma'ō aku o 90 kbps, ua maikaʻiʻoe.
No nā hui e hoʻokaʻawale i ka bandwidth a me ka hoʻonohonoho ponoʻana i kā lākou pūnaewele VoIP, pono pono nā luna ke kūpono i lalo a iʻole e hoʻonui i ko lākou mau kūlana maikaʻi e like me ka bandwidth maoli i loaʻa no ka mea hoʻohana. ʻO nā helu maʻamau he 90, 60 a 30 kbps, i kēlā me kēia hopena i loaʻa kaʻano o ka leo'ē aʻe. ʻO ka mea e koho ai,ʻo ia wale nō ka mea e hilinaʻi wale ai i ka bandwidth / quality trade-off e makemake ana ka hui e hana.
ʻO ke kumu o ka hoʻonohonoho ponoʻana o nā koina bandwidth i nā codecs ,ʻo ia nā algorithms ('āpana o nā papahana) e waiho nei i nā mea VoIP no ka hōʻiliʻili i nāʻike leo. ʻO nā codecs VoIP e hāʻawi i ka maikaʻi maikaʻi ke koi aku i kahi bandwidth. Eia kekahi lā,ʻo G.711, kahi o nā codecs maikaʻi loa a puni, koiʻia 87.2 kbps,ʻoiaiʻo ka iLBC e koi wale aku i 27.7; Makeʻo G.726-32 i 55.2 kbps.
I mea eʻike ai i ka nui o ka bandwidth āu i loaʻa a me ka pono no nā pono o kāu VoIP, hiki iāʻoe ke hoʻohana i nā ho'āʻo wikiwiki pūnaewele no ka meaʻole. Aia kekahi mau mea hana pololei a pololei, no nā hualoaʻa hou aku. ʻO kēia hiʻohiʻona kēia helu helu bandwidth VoIP.
He mea nui ke kuhikuhiʻana i ka nui o ka bandwidth e koiʻia ana a me ka nui o kaʻikepili i hoʻololiʻia i ka wā o nā piila e pili ana i ka polokalamu a iʻole ka lawelawe i hoʻohanaʻia, a ma ka huliʻana ma muli o nā kumuhana likeʻole e like me nā codecs i hoʻohanaʻia. Eia kekahi lā,ʻo Skype e hoʻopau ana i ka nui o nāʻikepili i kona hāʻawiʻana i ka leo kiʻekiʻe a me ka wikiō. Huakaʻi nuiʻo WhatsApp, akā ua nui ka nānāʻana i nā polokalamu māmā e like me Laina. I kekahi manawa, no ka maʻalahi o ka launaʻana, koho nā kānaka e hoʻopau i ka wikiō no ka maikaʻi o ka leo, no nā palena i ka bandwidth.
