He aha ka dualband ONU

Ua kapa ʻia ʻo Dualband ONU he 5G onu, a hiki ke kapa ʻia ʻo AC onu.

No laila, he aha ka pālua ʻelua onu?

E like me ka maʻamau o ka pūnaewele ueaʻole, ʻoi aku ka maikaʻi o ka onu pālua ma mua o ka onu-band hoʻokahi.ʻO ia ka onu kaulana loa i kēia mua aku.

IEEE 802.11ac

ʻO IEEE 802.11ac ka mea e hoʻomohala nei i ka 802.11 ka mea hoʻohana i ka 6GHz frequency band (ʻike pū ʻia ʻo ka 5GHz frequency band) no ke kamaʻilio ʻana o ka ʻoihana kūloko kūloko (WLAN).Ma ke kumumanaʻo, hiki iā ia ke hāʻawi i ka liʻiliʻi o 1 Gigabit i kēlā me kēia kekona bandwidth no nā kamaʻilio ʻana o ka ʻoihana pūnaewele ʻo WLAN, a i ʻole 500 megabits ma ke kekona (500 Mbit/s) no kahi bandwidth hoʻoili hoʻokahi.

Hoʻohana a hoʻonui i ka manaʻo o ka ea i loaʻa mai ka 802.11n, me ka: wider RF bandwidth (a hiki i 160 MHz), ʻoi aku ka nui o nā kahawai spatial MIMO (hoʻonui i 8), MU-MIMO , A me ka demodulation kiʻekiʻe (modulation, a hiki i 256QAM. ).He mea hiki ke pani i ka IEEE 802.11n.

ʻO kā mākou hui, ʻo Shenzhen HUANET Technology CO., Ltd hiki ke hāʻawi i nā ʻano onts dualband.Eia kekahi mau hiʻohiʻona onu pālua.

Hoʻohana ka 5GHz WiFi i kahi pūʻulu alapine kiʻekiʻe e lawe mai i ka hoʻohaʻahaʻa kahawai.Hoʻohana ia i nā kaha 22 a ʻaʻole hoʻopilikia kekahi i kekahi.Hoʻohālikelike ʻia me nā kaha 3 o 2.4GHz, hoʻemi nui ia i ka hōʻailona hōʻailona.No laila, ʻoi aku ka wikiwiki o ka hoʻouna ʻana o 5GHz ma mua o 2.4GHz.

Hiki i ka 5GHz Wi-Fi frequency band me ka lima o ka hanauna 802.11ac protocol ke hiki i ka wikiwiki o ka hoʻouna ʻana o 433Mbps ma lalo o ka bandwidth o 80MHz, a me ka wikiwiki o ka hoʻouna ʻana o 866Mbps ma lalo o ka bandwidth o 160MHz, i hoʻohālikelike ʻia me ka 2.4GHz ka wikiwiki o ka hoʻouna kiʻekiʻe. ka nui o 300Mbps Ua hoʻomaikaʻi nui ʻia.

Eia nō naʻe, he mau hemahema ka 5GHz Wi-Fi.Aia kona mau hemahema i ka mamao o ka hoʻouna ʻana a me ka hiki ke hele i nā pilikia.

No ka mea he hawewe electromagnetic ʻo Wi-Fi, ʻo kāna ʻano hoʻolaha nui ka hoʻolaha laina pololei.Ke hālāwai ʻo ia me nā pilikia, e hoʻopuka ʻo ia i ke komo ʻana, ka noʻonoʻo, ka diffraction a me nā mea ʻē aʻe.I waena o lākou, ʻo ke komo ʻana ka mea nui, a e kū mai kahi hapa liʻiliʻi o ka hōʻailona.ʻO ka noʻonoʻo a me ka ʻokoʻa.ʻO nā hiʻohiʻona kino o nā hawewe lekiō, ʻo ia ka haʻahaʻa o ke alapine, ʻoi aku ka lōʻihi o ka nalu, ʻoi aku ka liʻiliʻi o ka nalowale i ka wā hoʻolaha, ʻoi aku ka laulā o ka uhi, a ʻoi aku ka maʻalahi o ke kaʻe ʻana i nā mea pale;ʻoi aku ka kiʻekiʻe o ke alapine, ʻoi aku ka liʻiliʻi o ka uhi a ʻoi aku ka paʻakikī.E hele a puni nā pilikia.

No laila, ʻo ka hōʻailona 5G me ke alapine kiʻekiʻe a me ka lōʻihi hawewe pōkole he wahi liʻiliʻi liʻiliʻi, a ʻo ka hiki ke hele ma waena o nā pilikia ʻaʻole maikaʻi e like me 2.4GHz.

Ma ke ʻano o ka mamao o ka hoʻouna ʻana, hiki i ka 2.4GHz Wi-Fi ke hiki i ka uhi kiʻekiʻe o 70 mika i loko o ka hale, a me ka uhi kiʻekiʻe o 250 mika ma waho.A hiki i ka 5GHz Wi-Fi ke hiki i ka uhi kiʻekiʻe o 35 mika i loko.
