Kwi- networking wireless , izixhobo zombini-bhanti ziyakwazi ukuthumela kuzo zombini iindidi eziqhelekileyo eziqhelekileyo. Iinqununu zasekhaya ze-Wi-Fi zangoku zihamba ngee-band-band band routs ezixhasa ii-2.4 GHz kunye ne-5 GHz.
Iirejista zokuqala zesekhaya zokuvelisa ekhaya eziveliswe ekupheleni kwee-1990s nakwiminyaka yokuqala yee-2000 zaziqulethe i- 802.11b yomsakazo we-Wi-Fi osebenza kwi-band G 2.4. Ngethuba elifanayo, inani elininzi lamanethiwekhi oshishino axhasa ama- 802.11a (5 GHz). Iileta zokuqala ze-Wi-Fi zangaphambili-bhanti zakhiwa ukuxhasa amanethiwekhi axubekileyo anama-802.11a kunye no-802.11b.
Ukuqala nge- 802.11n , amazinga e-Wi-Fi aqala ukubandakanya ukuxhaswa kwe-double-band ye-2.4 GHz kunye ne-5 GHz njengomgangatho oqhelekileyo.
Izinzuzo ze-Networks Wireless Networks
Ngokunikezela ngezixhobo ezingafaniyo ezingenazintambo kwiqela ngalinye, ii-band-band 802.11n kunye ne- 802.11ac zithuthi zibonelela ngokuguquguquka okukhulu ekumiseni inethwekhi yasekhaya. Amanye amadivaysi asekhaya afuna ukuhambelana kwelifa kunye nokufikelela kwezaziso ezingaphezulu kwe-2.4 GHz xa abanye befuna i- bandwidth eyongezelelweyo yenethiwekhi eyinikwa ngu-5 GHz.
Iibhutri ezimbini zebhanki zibonelela iinkcukacha ezilungiselelwe iimfuno ngamnye. Amanethiwekhi amaninzi e-Wi-Fi aphethwe yimingcipheko engenazintambo ngenxa yokuxhaphaka kwezixhobo zobathengi be-2.4 GHz, njengama-oven microwaves kunye neefowuni ezingenasiphelo, zonke ezikwazi ukusebenza kuphela kumashishini angama-3 angabikho. Ikhono lokusebenzisa i-5 GHz kwi-router-band router inceda ukuphepha le miba kuba kukho iziteshi ezingama-23 ezingazange zisebenzise.
Iibhutri zombini-mabini zibandakanya i -Multi-Out Multi-Out Out (MIMO) . Ukudibaniswa kwee-radios ezininzi kwiqela elinye kunye ne-support-band inkxaso kunika ukusebenza okuphezulu kunxibelelwano lwekhaya kunokuba yeyiphi i-router band ebanikela.
Imizekelo yeeDual Band Wireless Devices
Akunjalo kuphela ii-routers zibonelela nge-wire-band wireless kodwa kunye ne-adapters ye-Wi-Fi kunye neefowuni.
IiRual Routs Wireless Routers
I-TP-LINK Archer C7 AC1750 I-AC-Band ye-Wireless I-AC Gigabit Router inama-450 Mbps kwi-2.4 GHz kunye ne-1300 Mbps kwi-5GHz, kunye ne-IP-based controlwidth control ukuze ukwazi ukubeka umda wokuhamba kwindlela zonke ezixhunyiwe kwi-router yakho.
I-NETGEAR N750 iDual Band ye-Wi-Fi iGigabit Router yimizi ephakathi nendawo enkulu kwaye iza ne-app ye-genie ukuze ugcine iithebhu kwinethiwekhi yakho kwaye ufumane uncedo lweengxaki xa ulungiswa.
Iifayile ze-Wi-Fi ze-Double Band
Izixhobo zeenethiwekhi ze-Wi-Fi ze-Double-band ziqukethe ii-2.4 GHz kunye ne-5 GHz ii-radios ezingenazintambo ezifana neendlela zokuhamba ezimbini.
Ngeentsuku zokuqala ze-Wi-Fi, ezinye iifowuni ze-Wi-Fi ze-laptop zixhaswa ngama-802.11a kunye ne-802.11b / g ii-radios ukuze umntu angakwazi ukudibanisa ikhompyutha yakhe kumanethiwekhi ashishino ngexesha lomsebenzi kunye namanethiwekhi asekhaya ngobusuku neveki. Ama-adapters angama-802.11n kunye nama-802.11ac angacwangciswa ukuba asetyenzise okanye iqela (kodwa kungabini ngexesha elifanayo).
Omnye umzekelo we-double band gigabit i-adapter ye-Wi-Fi yenethiwekhi yi-NETGEAR AC1200 WiFi USB Adapter.
Iifowuni zeeDual Band
Ngokufanayo nezixhobo zonxibelelwano ezingenazintambo ezingenazintambo, ezinye iifowuni zisebenzisa kwakhona amabini amabini okanye amaninzi amashishini axhulumaniso ahlukeneyo kwi-Wi-Fi. Iifowuni ezimbini zebhanki zenziwe ekuqaleni ukuxhasa i-3G GPRS okanye iinkonzo zeDEDGE kwi-0.85 GHz, 0.9 GHz okanye 1.9 GHz.
Amafoni athile axhasa i-tri-band (ezintathu) okanye i-quad-band (ezine).
Iimodem zee cell zitshintsha phakathi kwamacandelo ahlukeneyo kodwa azixhasi ukuxhunywa kwembini ngokufanayo.
