Makemake ʻoe pehea 5G ike loea hana? He mea maikaʻi, he aha nā mea maikaʻi a me nā mea ʻino o ka ʻenehana hou? He aha nā ʻano ʻekolu o 5G i kapa ʻia? Hoʻopili ka ʻatikala o kēia lā i nā mea āpau.
Ua mākaukau ka honua no 5G. ʻOi aku ka wikiwiki o ka ʻenehana ma mua o kona mau mua. Ma ka hopena o 2035, ua wānana ʻia e hoʻopuka ʻo 5G i ka USD 12.9 trillion i ka hana kūʻai aku a kākoʻo ma luna o 20 miliona mau hana. Ma ʻAmelika Hui Pū ʻIa wale nō, manaʻo ʻia e hoʻonui i 3.5 miliona mau hana hou a hoʻohui i ka USD 550 biliona i ka GDP. Ua hoʻokuʻu ʻo Apple i ʻelua mau hiʻohiʻona hou o kāna iPhones: iPhone 12 a me iPhone 13. Ua lako kēia mau iPhones hou me nā hoʻolālā 5G. ʻO Xiaomi kekahi o nā hui inoa kelepona i hoʻomaka i ka hoʻokomo ʻana i ka 5G i kā lākou huahana. kaomi i 'aneʻi e ʻike i nā kelepona Xiaomi e kākoʻo ana i ka ʻenehana 5G.
ʻO ka ʻenehana 5G hou e ʻae i nā mea hana e hoʻokaʻawale i kahi pūnaewele kino i loko o nā pūnaewele virtual lehulehu. Hiki iā lākou ke hoʻohana i nā mana ʻāpana like ʻole e like me ko lākou koʻikoʻi. Hiki i nā mea hoʻohana ke ʻike i kahi ʻike 360-degree o ka hana a hiki ke hoʻololi i waena o nā kahawai like ʻole i ka manawa hoʻokahi. E hoʻomaikaʻi nui ka wikiwiki o ka hoʻoili ʻikepili. Pēlā nō, hiki ke hoʻohana i nā ʻāpana pūnaewele e hoʻolimalima i kahi ʻāpana o ka pūnaewele e lawelawe i kā lākou pono ponoʻī.
E kūkulu ʻia ka ʻenehana me ka hoʻohana ʻana i nā kelepona liʻiliʻi kokoke i nā mea kākau inoa. E kau ʻia kēia mau keena ma luna o nā pou pono a me nā lako alanui, a loaʻa iā lākou nā antenna "akamai" hiki ke hoʻokele i nā kaola he nui i nā mea kākau inoa. ʻO kēia ka mea e hiki ai iā 5G ke hana ma nā pae mana haʻahaʻa ma mua o nā ʻōnaehana 4G o kēia manawa. Ua manaʻo ʻia ka ʻenehana hou e hōʻea i ka hoʻolaha piha ʻana ma 2020. ʻOiai he nui nā pono kūpono, he nui nā pilikia e lanakila ai ka ʻenehana. ʻOiai he nui nā kānalua a me nā pilikia, e hoʻololi kēia mau ʻenehana uila i ke ʻano o kā mākou kamaʻilio ʻana.
Ua palekana ʻo 5G?
ʻO ka pane he ʻae a ʻaʻole. ʻOiai ka hype e hoʻopuni ana iā 5G, he mea nui ia e hoʻomaopopo i ka nui o ka kānalua e pili ana i ka palekana o ka ʻenehana. ʻO ka hopohopo nui loa ka hopena o ke olakino. Ke kū nei, ʻike maikaʻi ka wā e hiki mai ana o 5G. Nui nā mea e kali ai. No ka hoʻomaka ʻana, hiki i ka ʻenehana 5G ke hoʻokaʻawale i kahi pūnaewele kino i loko o nā pūnaewele virtual. E ʻae ka ʻoihana pūnaewele i nā mea hoʻohana e hoʻohana i kahi ʻāpana ʻokoʻa o ka pūnaewele no nā noi like ʻole, e like me ke kamaʻilio wikiō.
Nā pōmaikaʻi o ka ʻenehana 5G hou
ʻOiai he mea hoʻoweliweli paha ka ʻenehana, maopopo nā mea maikaʻi o 5G. Hoʻololi ia i ka mākeke 4G nui loa me nā noi pili pūnaewele kiʻekiʻe. ʻO ka haʻahaʻa haʻahaʻa o ka ʻenehana he mea kūpono ia no ke kahe wikiō. Hiki i kona hilinaʻi kiʻekiʻe ke kākoʻo i ka wikiō a me ka leo. Eia kekahi, kōkua pū ʻo 5G i nā hāmeʻa e hoʻomau i ka pākaukau. Hiki i ka bandwidth adaptive ke hoʻololi i ke kelepona ma waena o ka wikiwiki o ka ʻikepili kiʻekiʻe a me ka haʻahaʻa, e mālama iā ia mai ka hoʻokahe ʻana i ka pākaukau.
I mea e hoʻokō pono ai, pono e loaʻa i nā pūnaewele kelepona 5G ke komo i ka mana backhaul kiʻekiʻe. ʻO ka backhaul maikaʻi loa no kēia ʻano pūnaewele ma luna o nā kaula fiber optical. Eia nō naʻe, ʻaʻole kēlā me kēia mea hoʻolako i nā mea kanu fiber i kā lākou mau mākeke a ʻaʻole hiki ke hoʻolimalima i ko lākou mau mea hoʻokūkū. ʻO ia ke ʻano he pono lākou e hoʻolimalima i ka mana mai nā ʻoihana kelepona a me nā mea hoʻokūkū. ʻOiai ʻike ʻia nā pōmaikaʻi o ka ʻenehana, ʻike maopopo ʻia nā hemahema o kēia ʻenehana.
Pehea ka ʻokoʻa o 5G ma mua o 3G, LTE a me 4G?
Hoʻohana pū ʻo 5G i kahi ākea ākea o nā alapine ma mua o 4G. Hoʻohana ʻo ia i ka ʻano nalu millimeter-wikiwiki loa. He mau millimeters wale nō ka lōʻihi o kēia mau nalu a ʻoi aku ka nui o ka alapine ma mua o nā hawewe lekiō 4G. ʻO ka wikiwiki o nā nalu, ʻoi aku ka nui o ka ʻikepili hiki iā lākou ke lawe. ʻO ka hopena, hiki i ka 5G ke hoʻololi i nā ʻano ʻoihana a me nā huahana. Hiki iā ia ke hoʻololi i ke ʻano o kā mākou hana, ola, a pāʻani.
Hoʻohana ʻo 5G i nā alapine lekiō ʻoi aku ka liʻiliʻi o ka cluttered. Hiki iā ia ke hoʻouna i nā ʻike hou aʻe me ka wikiwiki. E hoʻohana ʻia ka ʻenehana i ka mana o nā hale akamai me nā mana kiʻekiʻe. Hiki i ka ʻenehana ke hāʻawi wikiwiki i ka ʻike, hoʻemi i ka latency, a hoʻonui i ka nui o ka ʻikepili. E ʻoi aku ka wikiwiki o kēia hanauna hou o nā pili uila ma mua o nā hanauna i hala. E ʻae ia i ka hoʻomohala ʻana i nā lawelawe a me nā noi hou. A, ʻoiai ʻo kona paʻakikī, ʻaʻole i mākaukau ka ʻenehana e hana pono.
ʻO ka wikiwiki o 5G e wikiwiki loa. He hoʻonui koʻikoʻi ia LTE a 3G E ʻoi aku ka hilinaʻi ma mua o 4G, no laila hiki iā ia ke hoʻokūkū me nā ISP i loaʻa. Hiki iā ia ke hoʻohana i nā noi hou, e like me ka virtual a me ka mea i hoʻonui ʻia. Eia kekahi, e hoʻopili ʻia ʻo 5G me nā kelepona 4G. Ma waho aʻe o kēia, he kōkua nui ka ʻenehana no nā wahi kua'āina.
ʻO nā ʻano like ʻole o 5G: haʻahaʻa haʻahaʻa, waena waena a kiʻekiʻe
Nui nā ʻano like ʻole o 5G. ʻO ka mua, e kamaʻilio kākou e pili ana i nā pūʻulu like ʻole. ʻOi aku ka maikaʻi o ka band kiʻekiʻe no nā wikiwiki kiʻekiʻe, ʻoiai ʻoi aku ka maikaʻi o ka band haʻahaʻa no nā mamao pōkole. ʻOiai hiki i ka hui kiʻekiʻe ke hoʻokele i nā paia, wikiwiki loa ia, ʻoiai he haʻahaʻa kona wahi uhi. Hāʻawi ʻo Mid-band i ka waena-latency a me kahi ākea liʻiliʻi. Hāʻule ka hui haʻahaʻa i ka ʻāpana poni. No ka laʻana, kūkulu ʻo T-Mobile i kāna pūnaewele 5G holoʻokoʻa me ka hoʻohana ʻana i ka band 600 megahertz.
ʻO 5G haʻahaʻa haʻahaʻa ka hoʻololi kumu o ka ʻenehana. Loaʻa iā ia kahi ākea ākea a hiki ke hele i kahi lōʻihi. Ma kahi o %20 ʻoi aku ka wikiwiki ma mua o 4G, a hoʻohana ʻia e nā hale kīwī. ʻO ka ʻoiaʻiʻo, ua manaʻo ka Federal Communications Commission e hiki ke uhi ʻia nā band haʻahaʻa haʻahaʻa 5G ma waena o 600 MHz a me 900 MHz. ʻOiai ka lōʻihi loa o kēia, he mea hoʻomohala maikaʻi loa ia.
ʻAʻole wikiwiki ka lawelawe 5G haʻahaʻa e like me ka hui kiʻekiʻe, akā hiki ke hoʻomaikaʻi i ka wikiwiki o kāu kelepona. Manaʻo ʻia ʻo ka mid-band version he wahi momona o ka hana no kekahi mau makahiki. Eia naʻe, i kēia manawa, aia nō ka ʻenehana i kona wā mua. ʻO ia hoʻi, ʻaʻole mākaukau nā kelepona ʻoi loa e hoʻohana pono i nā pūnaewele 5G kiʻekiʻe.
ʻO 5G haʻahaʻa haʻahaʻa ka mea kaulana loa o nā ʻekolu. ʻAʻole ʻo ia ka mea ʻoi loa ka hyped a i ʻole ka ʻoi loa o ka ʻekolu. Akā ʻo ia ka mea maʻamau a loaʻa iā ia ka laulā o 600 a 700 MHz. ʻO ka laina waena mai ka 2.5 GHz a i ka 4.2 GHz, ʻoi aku ka nui o ka laulā ma mua o ka spectrum haʻahaʻa. Akā ʻo ka ʻaoʻao haʻahaʻa, ʻaʻole hiki ke hele i kahi lōʻihi ma muli o nā keʻakeʻa, me nā hale a me nā mea paʻa. ʻO ia hoʻi, ʻoi aku ka kaohi ʻia ma nā kūlanakauhale. Eia nō naʻe, ʻo ka hui kiʻekiʻe mai 24 a 39GHz. Hoʻohana ʻo 5G kiʻekiʻe i nā alapine ma nā pūʻali haʻahaʻa a me waena. Loaʻa pinepine kēia mau pūʻulu i nā wikiwiki hoʻoiho i nā gigabits i kekona.
ʻOiai ʻo ka ʻano ʻokoʻa kiʻekiʻe ka mea i hoʻohiki nui ʻia, ʻaʻole like me ka hoʻohiki ʻana o ka mid-band 5G variant. Hāʻawi kona ʻano haʻahaʻa haʻahaʻa i ka uhi ʻana, akā hiki i kāna alapine haʻahaʻa ke hele i kahi mamao.
