Nā Kūmole Kūmole o 3G
ʻO 3G ke kolu o ka hanauna o kaʻenehanaʻenehana pūnaewele. Hōʻea mai ia me nā mea hoʻonui i nāʻenehana uila o ka wā ma mua, e like me ka wikiwiki nui, kaʻike multimedia ulu mua, a me ka holoʻana o ke ao holoʻokoʻa.
Hoʻohana nuiʻiaʻo 3G me nā pūnaewele a me nā lima lima e like me keʻano e hoʻohui i ke kelepona i ka pūnaewele aiʻole i nāʻenehana IP'ē aʻe e hiki ai ke hana i nā leo a me nā wikiō, e kiʻi a hoʻouka i nāʻikepili, a e nalu i ka Pūnaewele.
Mōʻaukala
Ua hahaiʻo 3G i kahi'ōnaehana o G i hoʻomaka ai ka ITU i ka makahiki 1990. ʻO ke kumu hoʻohālikelike ka mea i kohoʻiaʻo IMT-2000 (International Mobile Communications 2000). No laila, ke hele mai neiʻo 3G ma hope o 2G a me 2.5G , nāʻenehana lua.
2G i keʻenehana, a me nā mea'ē aʻe,ʻo ka Global System for Mobile ( GSM ). 2.5G laweʻia nā paepae i waena o 2G a me 3G, me ke Keʻena Radio Service Palekana ( GPRS ), Nā hōkūʻikepili i hoʻonuiʻia no ka GSM Evolution ( EDGE ), Universal Mobile Telecommunications System (UMTS), a me nā mea'ē aʻe.
Peheaʻo 3G ke maikaʻi?
Loaʻaʻo 3G i kēia mau mea hou ma luna o 2.5G a me nā papahana mua:
- ʻO ka nui o ka wikiwikiʻikepili.
- Hoʻonui i nā leo a me nā wikiō.
- Manaʻo kōkua Videoconferencing.
- Ka pūnaewele pūnaewele a me ka WAP ma nā piʻi kiʻekiʻe.
- Ke kākoʻo IPTV (TV ma o ka pūnaewele).
Nā Kūlana Kiʻi
ʻO ka loli hoʻololi no nā kikowaena 3G ma waena o 128 a me 144 kbps (kilobits per second) no nā mīkini wikiwiki, a 384 kbps no nā mea lohi (e like me ka hele wāwae pedestrians). No ka LANs ahokore kūpono, ʻoi aku ka wikiwiki ma'ō aku o 2 Mbps (2,000 kbps).
ʻO 3G he'ōnaehana o nāʻenehana a me nā kūlana e like me ka W-CDMA, WLAN, a me ka leka uila, a me nā mea'ē aʻe.
Manaʻo no ka hoʻohana
ʻO kahi polokalamu e like me ka 3G a like paha, e like me ke kelepona a iʻole ka pakuhi, he,ʻoiaʻiʻo,ʻo ka mea mua. ʻO kēia kahi i loaʻa ai ka inoa "3G phone" mai-kahi lemu uila he 3G mau hana. ʻAʻole i pili kēia hua'ōlelo me ka heluna o nā kiʻi kamera a iʻole ka hoʻomanaʻo iā ia. ʻO kahi hiʻohiʻona ka iPhone 3G.
Loaʻa i nā'ōnaehanaʻelua nā kiʻiʻelua mai ka hoʻohanaʻana o kaʻenehana i nā mea wikiō e pono ai i ka mea hoʻohana, kahi e pono ai i kahi kamera e pili ana i ka mea hoʻohana.
ʻAʻole like me Wi-Fi , kahi e loaʻa ai iāʻoe ma ka piko o ka piko pele , ponoʻoe e inoa inoa i kahi mea lawelawe e loaʻa i ka hui pūnaewele 3G. ʻO kēiaʻano lawelawe ke kapaʻiaʻo ia he maheleʻikepili a iʻole ka papahana kikowaena.
Hoʻokomoʻia kāu pūnaewele i ke kelepona 3G ma o kāna kāki SIM (i keʻano o kahi kelepona) a iʻole i 3 ke kikowaenaʻike (hiki keʻano o nāʻano likeʻole, e like me USB , PCMCIA, a me nā mea'ē aʻe). i kūʻaiʻia e ka mea lawelawe.
ʻO keʻano kēia e pili ana ka pūnaewele i ka pūnaewele i loko o ka kōnae 3G. ʻO kaʻoiaʻiʻo, ua hoʻihoʻi ka pūnaewele i nāʻenehana kahiko,ʻo ia ke kumu e loaʻa ai i ke 3G 3G ke kiʻina maʻamau 2G lawelawe ke loaʻa ināʻaʻole lawelawe 3G.
He aha ke kumu kūʻai 3G?
ʻAʻole kūleʻale ka 3G, akā he mea pono i nā mea hoʻohana i pono ka pilina ma ka neʻe. Hāʻawi kekahi mea hoʻolako iā ia i loko o nā mea kumukūʻai nui, akāʻo ka hapanui o lākou he mau manaʻo i kahi e hoʻohana ai ka mea hoʻohana no ka nui o ka hoʻololiʻana, no ka mea,ʻo ka'ōnaehana ke kūʻaiʻia. Eia kekahi laʻana, aia nā hoʻonohonoho lawelawe ma kahi o kahi pālahalaha no ka gigabyte nui o kaʻikepili i hoʻololiʻia, a me ka uku pākahi megabyte a iʻole ka nui-gigabyte ma hope o kēlā.
3G a me Voice
ʻO ke kelepona hoʻohanaʻole he ala no nā mea hoʻohana pūnaewele e hana ai i nā kelepona liʻiliʻi a kūʻaiʻole paha ma ke ao holoʻokoʻa a e mālama i ka nui o ke kālā no nā noi a me nā lawelawe leka hou. Loaʻa kaʻenehana o 3G i ka loaʻaʻana ma ka neʻeʻana, e like me ka Wi-Fi, kahi i kaupalenaʻia i kekahi mau mīka e pili ana i ka mea hoʻopuka emitter .
ʻO kahi mea hoʻohana me kahi 3G a me ka hoʻolālāʻikepili ua hoʻomākaukau ponoʻia no ka hanaʻana i nā pihi pūnaewele kūikawā. Pono lākou e hoʻokomo i kekahi o nā polokalamu VoIP liʻiliʻi i loaʻaʻole, e like me Viber, WhatsApp, a iʻole Telegram.
