Ke hele mai nei i nā paʻi like ʻole i ka media, a me ke kūkākūkā ʻana i waena o nā hoaaloha i nā hōʻike lanakila o nā mea hoʻohana kelepona e pili ana i ka mākaukau e hoʻomaka i nā kamaʻilio 5G, nui ka poʻe o mākou e noʻonoʻo pono i nā manaʻo maikaʻi loa. ʻO ka mea pōʻino, ma waho aʻe o ka lanakila ʻana i nā puʻupuʻu IT ʻālohilohi, ua loaʻa i nā kūlana kamaʻilio kelepona hou ko lākou mau pitfalls, ʻaʻole mākou e noʻonoʻo mau.

No ka mea kūʻai nui o nā lawelawe lawelawe kelepona, ʻaʻole koʻikoʻi nā nuances o ka ʻenehana i hoʻohana ʻia, akā ʻehā mau "pou" e pili pono ana: ke kumukūʻai, ka uhi, ka wikiwiki a me ka latency pūnaewele. ʻO kēia nā ʻāpana i hoʻohana pinepine ʻia e nā mea kūʻai aku o nā ʻoihana hoʻomohala e hoʻolaha ana i ke kūlana kamaʻilio kelepona hou. No laila, me kēia mau ʻāpana, ua hāʻawi mai kēlā me kēia maʻamau i hoʻokō ʻia iā mākou i kahi mea hou aʻe.
ʻO ka pōmaikaʻi hiki ʻole ke wehewehe ʻia o ka neʻe ʻana i hāʻawi ʻia e nā kelepona iā mākou i ka makahiki 90 ua uhi wale ʻia e ka hiki ke hoʻohana i kāu hāmeʻa paʻa ma ke ʻano he modem pūnaewele piha i nā pūnaewele 2G. Ma hope o ka loaʻa ʻana o ka hiki ke komo i ka leka uila, nā ʻano ʻano o nā puka ʻike, a i ka manawa like ʻole e hoʻopaʻa iā ʻoe iho i kahi ʻōnaehana uea, ua ʻike ʻia kahi pahuhopu hou ma ka lewa - e lanakila ai i ka pale wikiwiki kiʻekiʻe, a me ka hoʻohaʻahaʻa ʻana i ka ping. He mea kaumaha loa ia ma nā pūnaewele 2G. ʻO ka hoʻokō piha ʻana i ka maʻamau kamaʻilio 3G ʻaʻole paha i like me ka hoihoi a me ka hoihoi e like me ka 2G, akā naʻe, ua lilo ia i mea hou no mākou āpau. Ke hoʻohālikelike nei i ka 3G me kona mua, hiki ke ʻike ʻia ʻo ka wikiwiki maoli, no ka hoʻoiho ʻana a me ka hoʻouka ʻana, ua hoʻonui ʻia he ʻumi! Ma waho aʻe o ka piʻi nui o ka wikiwiki, ua loaʻa iā mākou ka hōʻemi ʻana i ka latency pūnaewele i kahi ʻoluʻolu 50 ms, ʻo ia kahi kauoha o ka nui ma mua o 2G me kāna 200+ ms. Me ka hiki ʻana mai o ke kolu o ka hanauna o nā kamaʻilio kelepona, ua lilo ka Pūnaewele kelepona i mea hoʻokūkū hoʻokūkū maoli i kāna hoa uea.
ʻO 4G, ʻoi aku ka haʻahaʻa ma mua o kona mua. ʻAe, ʻoiaʻiʻo, me ka hiki ʻana mai o ka maʻamau hou, ua lilo ka Pūnaewele i ʻoi aku ka "wikiwiki", ua ʻoi aku ka nui o nā pūnaewele. I ka manawa like, mai ka manaʻo o ka kūleʻa pāʻoihana, ua lilo ʻo 4G i mea kānalua loa no nā mea lawelawe kelepona; ʻo nā mea hoʻohana e hāʻawi ana i nā ʻāina ulu i ʻike i ka nāwaliwali o ka lawelawe. ʻO nā wikiwiki kiʻekiʻe o 4G, ma ke kumumanaʻo a hiki i 1 Gbit/s, e ʻakaʻaka wale nō ka mea kūʻai nui. ʻO kahi pānaʻi kaulana loa no ka hoʻohana maʻamau o ka maʻamau ka loaʻa ʻana o kahi helu kūpono o nā kahua kahua 4G. I nā makahiki 5 i hala iho nei o ka hoʻomohala ʻana, ua uhi ʻia ka uhi ʻana o 4G ma Kelemania, Farani, a me Beretania ma kahi o 99% o ka heluna kanaka, akā ma ka pae honua he ʻokoʻa kēia ma mua o ke kānāwai. Inā mākou e lawe i ka hakahaka post-Soviet, hiki iā mākou ke ʻike aia nō ka 4G ma ke kahua o ka hoʻopukapuka kālā a me ka hoʻokō. E kū'ē i kēia kāʻei kua, he aha ka mea e kali nei iā 5G?

ʻO ka ʻoiaʻiʻo, ua hana ʻia ka lele nui mai 1G a i 4G pūnaewele i loko o nā palena o kahi kaʻina hana ʻenehana hoʻokahi. ʻO kēlā me kēia "G" ma hope mai, he ʻano liʻiliʻi ia, kahi mana hou o kona mua. ʻO kēia, ma ka laulā, ʻaʻole kahaha ka ʻike e alakaʻi iā mākou i ka hoʻomaopopo ʻana i ke kūlana o kēia manawa - ua kokoke mākou i nā palena o ka ʻenehana a mākou e hoʻohana ai i lalo o nā pūnaewele kelepona hou. ʻO ka hoʻonui ʻana i ka amplitude o ke kahawai hoʻouna a me nā ʻano hou o ka modulation hōʻailona ua hāʻawi iā mākou i ka manawa e hoʻonui ai i ka nui o ka ʻike i hoʻouna ʻia i kēlā me kēia manawa, akā i ka wā e hiki mai ana ka piʻi nui ʻana o ka wikiwiki o ka ʻoihana wale nō ma o ka hoʻonui nui ʻana. ke alapine hana, a piha loa kēia i nā hopena.
ʻO ka manaʻo o ka helu o nā kahua kahua e uhi i ka 100% o ka ʻāina o Ukraine ma muli o kā lākou mau alapine hana.
ʻO ka ʻoiaʻiʻo, e like me ka papa physics kula, e like me ka piʻi ʻana o kēia mau alapine like, piʻi nui hoʻi kā lākou attenuation, a ʻo ka mea hoʻi, ke emi nei ka hiki ke komo o nā hawewe radiomagnetic. No ka mea hoʻolako lawelawe, hoʻokahi wale nō mea kēia, he hoʻonui radical i ka helu o nā kahua hoʻokumu, a, no laila, he hoʻonui radical i ka hoʻokomo ʻana i kāna ʻoihana, ka mea e lawe ʻia e ka mea kūʻai. Inā hiki ke hoʻokō ʻia kēia ʻano hoʻohālike ma nā kūlanakauhale, ma muli o ka nui o ka heluna kanaka, a laila ʻaʻole pono ka uhi ākea.
ʻO kahi koho ʻē aʻe i nā alapine kiʻekiʻe hiki ke hoʻokomo i ka 5G ma nā alapine haʻahaʻa, a hiki i ka 1 GHz, hiki i kēia ke hāʻawi i ka uhi piha o nā ʻāina ākea, akā i kēia hiʻohiʻona, ʻaʻole ʻike maoli ka mea hoʻohana i nā loli i ka hana. o kāna gadget, mai ka 4G i kamaʻāina mua iā ia. ʻO ka hopena, hiki i ka 5G ke lilo i poʻo poʻo no nā mea kūʻai aku, me ka loaʻa ʻana o kahi kumu no ka wā e hiki mai ana, e lawe ana i nā pōmaikaʻi hohonu, e ʻōlelo, no ka honua LoT, akā ʻaʻole maopopo ka mea hoʻohana nui no ia.
Pehea inā?
Inā he mea hoʻokūkū ʻo 5G i ka 4G ma nā alapine haʻahaʻa, a laila kūpono ke manaʻo e hoʻokuʻu ʻia ka maʻamau hou ma nā alapine o 5 GHz a ʻoi aku. ʻOiaʻiʻo, e like me ke kūlana hou, hiki ke hoʻokuʻu ʻia i nā alapine a hiki i 300 GHz. Eia naʻe mākou e ʻike ai i kahi pilikia hou: ʻo ka hoʻohana ʻana i ka nalu millimeter e kahi mea kelepona e hoʻāla ai i kahi hakakā me kahi mea hoʻokūkū ma ke ʻano o ka ʻenehana WiFi.
He ʻenemi kahiko ʻo WiFi no nā mea hoʻohana kelepona. Ma hope o ka lawe ʻana i ke kumu gula ma waena o ke kumukūʻai o ka megabyte "wied" a me ke kiʻekiʻe o ka neʻe ʻana, ua hoʻokumu paʻa ʻo ia iā ia iho i loko o ko mākou mau hale, nā keʻena, nā halihali a me nā paka. No ka loaʻa ʻana o nā loina o ka lawe ʻana i ka ʻikepili uila e like me 5G, ua hahai ka ʻenehana WiFi i kona ala ponoʻī o ka hoʻomohala ʻana a paʻa pono i kāna niche kūʻokoʻa a hiki i kēia manawa.
ʻO kaʻoiaʻiʻo, ua lōʻihi loa ke kūlana me nā kamaʻilio IT, a eia ka mea. ʻAʻole maopopo ʻo wai ka mea mua i komo i loko o kāna māla - nā mea hoʻolako pūnaewele me kā lākou IP telephony i nā mea kelepona, a i ʻole nā mea hana me kā lākou 2-3-4-5G i hoʻomaka e lawe aku i ka Internet traffic mai nā mea hoʻolako liʻiliʻi, akā i kēia manawa aia kahi paio pili. Ua lilo maoli nā mea hoʻohana pūnaewele i nā mea hoʻolako pūnaewele, ua mau nā mea hoʻolako pūnaewele i nā mea hoʻolako pūnaewele, akā i ka manawa like i hoʻomau ʻia i ka hoʻopili ʻana i kahi hoʻolālā pūnaewele ʻokoʻa. ʻO ka mea nui, ua ʻike mākou i kahi loli convergent ma IT. Inā mākou e noʻonoʻo i ka maʻamau 5G i hoʻokō ʻia ʻaʻole mai ka manaʻo o ka hoʻololi ʻana i ka hanauna 4G, pono ia e hoʻololi loa, e like me ka mea i hana ʻia me 2-3G ma mua, akā e kāhea iā ia, e ʻōlelo, he mea pepehi WiFi? I kēia hihia, hiki ke hoʻomaopopo ʻia ka nui o nā mea like ʻole a me nā mea ʻē aʻe e pili ana me 5G.
Nā hopena
ʻO nā ala pūnaewele e hiki ai iā mākou ke kamaʻilio me ka honua holoʻokoʻa he like ia no ka mea hoʻohana kelepona nui a me kahi mea hoʻolako pūnaewele uea home liʻiliʻi. Hoʻomaka ka ʻoihana no nā mea ʻelua ma ka pae hoʻolako mea kūʻai aku. Pehea ʻoe a me aʻu e komo ai i ka World Wide Web a aia kahi ʻoihana multi-biliona kālā i hana ʻia ma nā ʻenehana like ʻole, nā lako, a me nā hōʻailona. ʻO ke kūlana i ka wā e hoʻohana ai mākou i ʻelua ala ʻokoʻa i ka hoʻonohonoho ʻana i ke komo ʻana i ka Pūnaewele ma mua i kūpono, a ʻike ʻia ʻaʻole e pau kēia i ka lā ʻapōpō, akā ke hoʻoikaika nei ka honua i ka maʻalahi. ʻO ka hōʻole ʻana i ka hoʻohana ʻana i nā lawelawe o nā mea hoʻolako maʻamau, ʻo ia ka hopena o nā hui e hana ana i nā ala āpau e komo ai i ka Pūnaewele ma o nā pūnaewele kelepona honua. Nā modula kamaʻilio ākea, nā hāmeʻa "māmā" āpau mai WiFi ʻole i koi ʻia, Bluetooth, nā ʻāpana LAN. Centralized hoihoi 'ia o ke kauoha me ka hoʻonohonoho 'ana o ka hoʻomau 'ia uhi, elimination (significant ho'ēmi) o ka lekiō alapinepine haumia i loko o ke keʻena, o ka oi aku hale hale, e maopopo leʻa pono i ka hope consumer. He ino maoli anei? Malia paha ʻo ia ka manawa e hana ai i kēia lele qualitative?
E ʻōlelo paha kekahi he mea lapuwale kēia mau mea, ʻōlelo lākou e hahai ana ʻo WiFi i kāna ala ponoʻī o ka hoʻomohala ʻana a loaʻa iā ia kahi hoʻonohonoho kūpono o nā hiʻohiʻona e ʻae ʻole ia e make wale. Malia paha, ma nā kamepiula hou hiki iā ʻoe ke loaʻa i ka Bluetooth a me kahi hoʻopuka RJ-45, akā liʻiliʻi a liʻiliʻi pinepine. He aha ka WiFi i hana ai iā lākou i kekahi manawa .
Me kēia hoʻomohala ʻana o nā hanana, hoʻokahi wale nō mea e makaʻu ai: inā lilo ʻo WiFi i kahi anachronism a me ka nui o nā geeks, ʻaʻole anei mākou e hāʻule i loko o nā paʻa huluhulu o kekahi mau mea hoʻohana monopolistic? E hoʻomanaʻo hou anei mākou i nā mea i poina e like me ka moeʻuhane maikaʻi ʻole: ka hoʻolimalima kālā kekona no ke kelepona IP, nā uku "lio" no ka megabyte, ka hele ʻana a me nā mea leʻaleʻa ʻē aʻe? ʻO kēia mau nīnau a pau no ka lā ʻapōpō, akā ʻaʻole pono mākou e poina i kēia lā ʻo ka lā ʻapōpō, a ʻo ʻoe a me aʻu nā mea hōʻike.
