Mu makina osayira opanda waya , zida zamagulu awiri zimatha kusinthana m'magawo awiri osiyana-siyana. Mabungwe amakono a Wi-Fi amakhala ndi maulendo awiri omwe amagwiritsa ntchito mabanki omwe amathandizira ma GHz 2.4 ndi 5 GHz.
Zoyamba zapakompyuta zotengera kunyumba zomwe zinapangidwa kumapeto kwa zaka za m'ma 1990 ndi kumayambiriro kwa zaka za 2000 zinali ndi radiyo ya 802.11b ya Wi-Fi yomwe ikugwiritsidwa ntchito pagulu la 2.4 GHz. Panthaŵi imodzimodziyo, mabungwe ambiri amalonda anathandiza zipangizo 802.11a (5 GHz). Mawotchi oyambirira awiri ogwiritsira ntchito ma Wi-Fi amamangidwa kuti athandizidwe ndi ma makina osakaniza omwe ali ndi makasitomala 802.11a ndi 802.11b.
Kuyambira ndi 802.11n , miyezo ya Wi-Fi inayamba kuphatikizapo pulogalamu imodzi yawiri GHz ndi 5 GHz chithandizo monga choyimira.
Ubwino wa Dual Band Wosakaniza Mitundu
Pogwiritsa ntchito mapulogalamu opanda waya osagwiritsidwa ntchito pa gulu lirilonse, maulendo awiri a band-802.11n ndi 802.11ac amapereka zowonjezereka kusinthasintha popanga makonde a nyumba. Zida zina zapanyumba zimafuna kuti chiyanjano chikhale chogwirizana ndipo chizindikiro chachikulu chikufika kuti 2.4 GHz ikupereka pamene ena angapange zina zowonjezera zamagetsi zomwe 5 GHz amapereka.
Maulendo awiri ogwiritsira ntchito mabungwe amapereka mauthenga omwe apangidwira zosowa zawo. Ma intaneti ambiri a Wi-Fi amavutika chifukwa cha kuchuluka kwa zipangizo zamagetsi 2,4 GHz, monga mafunikiro a microwave ndi mafoni opanda zingwe, zonse zomwe zingagwiritsidwe ntchito pazitsulo zitatu zosagwirana. Kukwanitsa kugwiritsa ntchito GHz 5 pa router-band router kumathandiza kupewa nkhaniyi popeza pali njira 23 zosagwiritsidwa ntchito zomwe zingagwiritsidwe ntchito.
Mawotchi awiri omwe amagwiritsidwa ntchito pawiri amapezanso maulendo a ma mulingo-ambirimbiri (MIMO) . Kuphatikizidwa kwa ma radiyo ambiri pa gulu limodzi pamodzi ndi chithandizo chamagulu awiri amapereka ntchito yoposa yamtundu wa makompyuta kusiyana ndi zomwe mabomba amodzi angapereke.
Zitsanzo za Dual Band Wireless Devices
Ma router ena amangopereka opanda zingwe opanda zingwe komanso makasitomala amtundu wa Wi-Fi ndi mafoni.
Dual Band Wireless Routers
TP-LINK Archer C7 AC1750 Dual Band opanda waya Gigabit Router ili ndi 450 Mbps pa 2.4 GHz ndi 1300 Mbps pa 5GHz, komanso kulamulira kwapadwidth kulamulira kwa IP kuti muthe kuyang'anitsitsa kayendedwe ka zipangizo zonse zogwirizana ndi router yanu.
NETGEAR N750 Dual Band Wi-Fi Gigabit Router ndi nyumba zapakati mpaka zazikulu komanso imabwera ndi pulogalamu ya genie kuti muthe kusunga ma tepi pa intaneti yanu ndi kupeza chithandizo kuthetsa ngati kukonzekera kuli kofunikira.
Ma Adapt a Dual Band a Dual Band
Ma adapala awiri ogwiritsira ntchito ma Wi-Fi ali ndi ma-2.4 GHz ndi 5 GHz opanda ma radios omwe amafanana ndi ma-routers awiri.
M'masiku oyambirira a Wi-Fi, adapala ena apakompyuta a Wi-Fi amawathandiza ma radio 802.11a ndi 802.11b / g kuti munthu akhoze kulumikiza makompyuta awo kuntchito zamalonda patsiku la ntchito ndi kunyumba usiku ndi sabata. Zida zatsopano 802.11n ndi 802.11ac zingakonzedwenso kuti zigwiritse ntchito band (koma osati panthawi yomweyo).
Chitsanzo chimodzi cha makina awiri ogwiritsira ntchito makanema a Wi-Fi ndi a NETGEAR AC1200 WiFi USB Adapter.
Dual Band Phones
Mofanana ndi zipangizo zamagetsi zamagetsi awiri, mafoni ena am'manja amagwiritsanso ntchito magulu awiri kapena angapo kuti mauthenga apakompyuta azisiyana ndi Wi-Fi. Mafoni awiri-band adapangidwa kuti athandize ma 3G GPRS kapena ma data EDGE pa 0,85 GHz, 0.9 GHz kapena 1.9 GHz mafoni.
Mafoni nthawi zina amathandiza maulendo angapo (band) (quad) kapena quad-band (anayi) maulendo omwe amayendetsedwa ndi ma selo kuti apititse patsogolo mawonekedwe osiyanasiyana a foni, zothandiza pamene akuyenda kapena akuyenda.
Ma modem amasinthana pakati pa magulu osiyanasiyana koma samagwirizana panthawi imodzi.
