Mune wireless networking , maviri-band zvigadzirwa zvinokwanisa kutumira mune imwe yemhando mbiri dzakasiyana-siyana dzinowanikwa. Mazuva ano Ma-Fi- home network ane ma- router - bandband router anotsigira mairi 2.4 GHz uye 5 GHz.
Chizvarwa chekutanga chemhuri maitiro routerta akabudiswa mukati mekupedzisira kwema1990 uye kutanga kwema 2000s aiva ne 802.11b Wi-Fi redhiyo inoshanda pa 2.4 GHz band. Panguva imwecheteyo, nhamba yakawanda yemabhizimisi mashizha akatsigira maidhi 802.11a (5 GHz). Yekutanga-band-Wi-Fi routers yakagadzirwa kuti ishandise mitambo yakavhengana ine vatengi vose 802.11a uye 802.11b.
Kutanga ne 802.11n , mitemo ye Wi-Fi yakatanga kusanganisira panguva imwechete-band 2.4 GHz uye 5 GHz kutsigirwa sechinhu chinowanikwa.
Kubatsirwa kweDual Band Wireless Networking
Nokupa mahwindo asingasviki interfaces yeboka rimwe nerimwe, mabhiriji maviri-band 802.11n uye 802.11ac anopa huwandu hunochinja pakugadzira musha weimba. Mamwe magetsi edzimba anoda kufanana kwenhaka uye chiratidzo chikuru chinosvika kuti 2.4 GHz inopa apo vamwe vangave vachida mamwe mawendeji emakwikwi ayo 5 GHz anopa.
Dual-band routers inopa hukama hwakagadzirirwa zvido zveumwe neumwe. Vakawanda veIndaneti vanobatwa nekushungurudzwa kusina mhepo nekuda kwekupararira kwezvinhu zve 2.4 GHz zvigadzirwa zvevatengi, sevhisi microwave uye mafoni asina cord, izvo zvese zvinogona kushanda pane zvikamu zvitatu zvisingabatsiri. Kukwanisa kushandisa 5 GHz pane vaviri-band router kunobatsira kudzivisa nyaya idzi sezvo kune 23 nheyo dzisiri dzekudzidzira dzinogona kushandiswa.
Dual-band routers inosanganisirawo Multiple-In Multiple-Out (MIMO) maonesheni eredhiyo. Kubatanidzwa kwemafirimu akawanda kune rimwe boka pamwe chete neshamwari mbiri-bhenekeri inopa hutano hwepamusoro hwekutengesa musha kune izvo zvigadziri zvebhanhire zvingagona kupa.
Mienzaniso yeDual Band Wireless Devices
Hazviiti chete kuti dzimwe nzira dzekushandisa dzinopa vaviri-band-wireless asiwo ma Wi-Fi network adapter nemafoni.
Dual Band Wireless Routers
I-TP-LINK Archer C7 AC1750 Dual Band Wireless AC Gigabit Router ine 450 Mbps pa 2.4 GHz uye 1300 Mbps pa5GHz, pamwe ne-IP-based bandwidth control kuitira kuti ugone kuongorora ruwendo rwezvinhu zvose zvakabatanidzwa router yako.
NETGEAR N750 Dual Band Wi-Fi Gigabit Router ndeyeimba yepakati kusvika kumahombekombe uye inouyawo ne-genie app kuitira kuti ugone kuchengeta mabhesi pawetaneti uye kuwana rubatsiro rwekugadzirisa kana chero kugadziriswa kuchidiwa.
Dual Band Wi-Fi Adapters
Dual-band Wi-Fi network adapters vane zvose 2.4 GHz uye 5 GHz dzisina wire radios dzakafanana ne-double-band routers.
Mumazuva ekutanga eWi-Fi, mamwe mapikisa e-Wi-Fi e-laptop anotsigirwa mairimusi mairi 802.11a uye 802.11b / g kuitira kuti munhu atange kuunganidza kombiyuta yavo kune mabhizinesi mashizha panguva yebasa rekushanda uye mishandura yemhuri usiku nevhiki. Zvitsva zvitsva zve 802.11n uye 802.11ac zvinogona kugadziridzwa kushandiswa kana band (asi kwete zvose panguva imwechete).
Mumwe muenzaniso wewadhi yebhandi gigabit Wi-Fi network adapta ndiyo NETGEAR AC1200 WiFi USB Adapter.
Dual Band Phones
Kufanana ne-dual-band wireless network equipment, dzimwe serofoni dzinoshandisawo mabhii maviri kana kupfuura kuti mafoni ekutaurirana akasiyana neWi-Fi. Dual-band foni dzakasikwa kuti dzitsigire 3G GPRS kana maDVD data data pa 0.85 GHz, 0.9 GHz kana 1.9 GHz mafaira eredhiyo.
Dzimwe nhepfenyuro dzimwe nguva dzinotsigira tri-band (zvitatu) kana quad-band (mana) mafaira ekufambisa kwemaferensi emagetsi kuitira kuti kuwedzere kusangana nemhando dzakasiyana dzematarefoni, zvichibatsira kana vachifamba kana kufamba.
Cell modems inoshandura pakati pemapoka akasiyana asi haibatsiri panguva imwechete yekubatana kwebhande.
