Dualband ONU imatchedwanso 5G onu, ndipo imathanso kutchedwa AC onu.
Ndiye dualband onu ndi chiyani?
Malinga ndi mulingo wa netiweki opanda zingwe, dualband onu idzakhala yabwino kuposa single-band onu.Idzakhala onu yotchuka kwambiri m'tsogolomu.
IEEE 802.11ac
IEEE 802.11ac ndi mulingo wolumikizirana wamakompyuta wopanda zingwe wa 802.11, womwe umagwiritsa ntchito 6GHz frequency band (yomwe imadziwikanso kuti 5GHz frequency band) polumikizirana ndi mawayilesi amderali (WLAN).Mwachidziwitso, imatha kupereka osachepera 1 Gigabit pa sekondi iliyonse ya bandwidth yolumikizana ndi ma multi-station wireless local area network (WLAN), kapena osachepera 500 megabits pamphindi (500 Mbit / s) pa bandwidth imodzi yotumizira.
Imatengera ndikukulitsa lingaliro la mawonekedwe a mpweya lochokera ku 802.11n, kuphatikiza: RF bandwidth (mpaka 160 MHz), mitsinje yambiri ya MIMO (kuwonjezeka mpaka 8), MU-MIMO , Ndi kutsika kwakukulu (kusinthasintha, mpaka 256QAM) ).Ndiwolowa m'malo mwa IEEE 802.11n.
Kampani yathu, Shenzhen HUANET Technology CO., Ltd imatha kupereka mitundu yonse ya ma onts amtundu wapawiri.Nawa zitsanzo za dualband onu.
5GHz WiFi imagwiritsa ntchito bandi yapamwamba kwambiri kuti ibweretse kuchepa kwa mayendedwe.Imagwiritsa ntchito mayendedwe a 22 ndipo sichisokonezana.Poyerekeza ndi mayendedwe a 3 a 2.4GHz, imachepetsa kwambiri kusanja kwa ma sign.Chifukwa chake kuchuluka kwa 5GHz ndi 5GHz mwachangu kuposa 2.4GHz.
Gulu la ma frequency a 5GHz Wi-Fi lomwe limagwiritsa ntchito protocol ya 802.11ac ya m'badwo wachisanu limatha kufikira liwiro la 433Mbps pansi pa bandiwifi ya 80MHz, komanso kuthamanga kwa 866Mbps pansi pa bandwidth ya 160MHz, poyerekeza ndi liwiro la 2.4GHz lapamwamba kwambiri. mlingo wa 300Mbps wakhala bwino kwambiri.
Komabe, 5GHz Wi-Fi ilinso ndi zolakwika.Zolakwika zake zimakhala pamtunda wotumizira komanso kuthekera kodutsa zopinga.
Chifukwa Wi-Fi ndi mafunde amagetsi, njira yake yayikulu yofalitsira ndikufalitsa mizere yowongoka.Ikakumana ndi zopinga, imatulutsa kulowa, kusinkhasinkha, kusokoneza ndi zochitika zina.Pakati pawo, kulowa ndilo lalikulu, ndipo gawo laling'ono la chizindikiro lidzachitika.Kulingalira ndi kusokoneza.Maonekedwe a thupi la mafunde a wailesi ndikuti kutsika kwafupipafupi, kutalika kwa kutalika kwa mawonekedwe, kutayika kochepa panthawi yofalitsa, kufalikira kwakukulu, komanso kumakhala kosavuta kudutsa zopinga;kumtunda kwafupipafupi, kufalikira kwazing'ono komanso kumakhala kovuta kwambiri.Pitani kuzungulira zopinga.
Chifukwa chake, chizindikiro cha 5G chokhala ndi ma frequency apamwamba komanso kutalika kwafupipafupi kumakhala ndi malo ocheperako, ndipo kuthekera kodutsa zopinga sikuli bwino ngati 2.4GHz.
Pankhani ya mtunda wotumizira, 2.4GHz Wi-Fi imatha kufika pamtunda wa mamita 70 m'nyumba, ndi kufalikira kwa mamita 250 panja.Ndipo 5GHz Wi-Fi imatha kufika pamtunda wa mamita 35 m'nyumba.
