Ke noʻonoʻo nei e kūʻai i kelepona hou no 5G kiʻekiʻe? E hana maikaʻi iā ʻoe iho: mai hana i kēia.
ʻO wai ka makemake ʻole i ka pūnaewele wikiwiki a me ka bandwidth kiʻekiʻe? Makemake nā kānaka a pau. ʻO ke kūpono, makemake nā kānaka a pau i ka fiber gigabit e hōʻea i ko lākou puka a i ʻole ke keʻena. Malia paha i kekahi lā pēlā. ʻO ka mea āu e loaʻa ʻole ai ʻo ka wikiwiki gigabit-per-second o 5G. ʻAʻole i kēia manawa, ʻaʻole ʻapōpō, ʻaʻole loa.
I kēia manawa, ʻōlelo nā hui telecom i nā mea he nui i hoʻokahi hoʻolaha ma hope o kekahi ʻaʻole ʻoiaʻiʻo. Akā ma kā lākou mau kūlana, he hoʻopunipuni ka 5G.
E hoʻomaka kākou me ka inoa ponoʻī. ʻAʻohe "5G" hoʻokahi. He ʻekolu mau ʻano me nā ʻano ʻokoʻa loa.
ʻO ka mea mua, ʻo 5G kahi haʻahaʻa haʻahaʻa 20G e hāʻawi i ka uhi ākea. Hiki i hoʻokahi hale kiaʻi ke uhi i nā haneli haneli mau mile. ʻAʻole ia he daimonio wikiwiki, akā ʻoi aku ka maikaʻi o ka wikiwiki o 3+ Mbps ma mua o ka wikiwiki 100 Mbps i paʻa ʻia me DSL kuaʻāina. A i nā kūlana kūpono, hiki iā ia ke hāʻawi iā ʻoe i ka wikiwiki XNUMX+ Mbps.
A laila aia ma waena o ka hui 5G, e hana ana ma ka laulā 1GHz a 6GHz a aia ma kahi o ka hapalua o ka uhi o 4G. Hiki iā ʻoe ke manaʻolana e loaʻa ka wikiwiki ma ka laulā 200 Mbps. Inā ʻoe ma ʻAmelika Hui Pū ʻIa, ʻaʻole paha ʻoe e hālāwai me ia. Hoʻopili wale ʻia , ka mea i hoʻoili i ka waena-frequency 5G me kahi pūʻulu kahawai o 2,5 GHz mai . Eia naʻe, ua lohi ia no ka mea ua hoʻohana mua ʻia ka hapa nui o kāna bandwidth.
Akā ʻo ka mea e makemake nui ai ka poʻe he 1 Gbps ka wikiwiki me ka latency ma lalo o 10 milliseconds. Wahi a , ma kahi o 40% o nā mea hoʻohana iPhone a me 33% o nā mea hoʻohana Android he nui a makemake nui paha i ke kūʻai ʻana i nā hāmeʻa 5G. Makemake lākou i kēlā wikiwiki, a makemake lākou i kēia manawa. A ʻo 18% o lākou e ʻōlelo nei ua maopopo lākou i ka ʻokoʻa ma waena o nā ʻano o nā hui pūnaewele 5G.
Kanalua. No ka mea inā maopopo lākou i kēia, ʻaʻole lākou e wikiwiki e kūʻai i kahi kelepona 5G. ʻIke ʻoe, no ka loaʻa ʻana o kēlā mau wikiwiki, pono ʻoe e loaʻa i ka nalu millimeter 5G-a hele mai me nā mea hōʻike he nui.
ʻO ka mea mua, he 150 mika ka lōʻihi o ia mau nalu. Inā ʻoe e hoʻokele nei, ʻo ia hoʻi a hiki i ka loaʻa ʻana o nā kahua kahua 5G ma nā wahi āpau, e nalowale ana ʻoe i kāu hōʻailona kiʻekiʻe. ʻOiaʻiʻo, no nā makahiki e hiki mai ana, inā ʻoe e hoʻokele, ʻaʻole hiki iā ʻoe ke hoʻohana i ka 5G kiʻekiʻe.
A inā ʻoe i loko o kahi kahua kahua 5G, nā mea āpau - aniani pukaaniani, lāʻau, pā, etc. - hiki ke ālai i kāna hōʻailona alapine kiʻekiʻe. No laila, hiki i kahi transceiver 5G ma kou kihi alanui a ʻaʻole hiki iā ʻoe ke kiʻi i kahi hōʻailona kūpono.
Pehea ka hewa? , Ke hana nei ka mea hoʻolako kelepona kelepona nui o Iapana, i kahi ʻano aniani pukaaniani hou e hiki ai i ka millimeter-wave 5G ke hele. Akā ʻaʻole makemake paha ka hapa nui o ka poʻe e hoʻopuka i kekahi mau tausani kālā e hoʻololi i nā puka makani e hoʻohana wale i kā lākou kelepona.
E noʻonoʻo paha mākou he kelepona 5G kāu a ke hilinaʻi nei ʻoe hiki iā ʻoe ke komo i ka 5G - pehea ka nui o ka hana āu e manaʻo ai? Wahi a kahi kolamu ʻenehana ʻo Washington Post , hiki iā ʻoe ke manaʻo he "pilikia" ʻo 5G. He kūpono, hiki iā ʻoe ke hilinaʻi i kēia:
"E ho'āʻo i ka wikiwiki AT&T o 32 Mbps me kahi kelepona 5G a me 34 Mbps me kahi kelepona 4G. Ma T-Mobile, loaʻa iaʻu he 15 Mbps ma 5G a me 13 Mbps ma kahi kelepona 4G. ʻAʻole hiki iā ia ke hōʻoia iā Verizon. Akā ʻoi aku ka wikiwiki o kāna kelepona 4G ma mua o kāna kelepona 5G.
ʻOiaʻiʻo hōʻike ʻo ka awelika wikiwiki o nā mea hoʻohana 5G ma US he 33,4 Mbps. ʻOi aku ka maikaʻi ma mua o 4G, akā ʻaʻole "Wow!" He ʻoluʻolu kēia!”, ka mea a ka hapa nui o ka poʻe e moeʻuhane nei. ʻOi aku ka hewa o kēia ma mua o nā ʻāina ʻē aʻe e hoʻohana ana i ka 5G koe wale nō ka UK.
Eia kekahi, e loaʻa iā ʻoe ka 5G 20% o ka manawa. Inā ʻaʻole ʻoe e noho a hana paha ma kahi kokoke i kahi transceiver hawewe millimeter, ʻaʻole ʻoe e ʻike i ka wikiwiki i ʻōlelo ʻia a i ʻole kekahi mea kokoke iā lākou. No ka pololei, mai manaʻo e lilo ka 5G kiʻekiʻe kiʻekiʻe a hiki i 2025. A i ka hiki ʻana mai o kēlā lā, kanalua e ʻike mākou i nā wikiwiki gigabit-kekona maoli.
Hiki ke loaʻa ka ʻatikala kumu .
