Vim li cas Dual-Band Routers yog qhov zoo rau kev sib sim Wireless Network

Hauv wireless networking , cov cuab yeej siv dual-qhwv muaj peev xwm sib kis tau ntawm ob qho kev sib txawv ntawm cov qauv sib txawv. Niaj hnub nimno Wi-nkaus tsev tes hauj lwm feature dual-band broadband routers uas txhawb nqa 2.4 GHz thiab 5 GHz raws.

Kev ua haujlwm thib ib hauv tsev ua haujlwm hauv lub xyoo 1990 thiab thaum ntxov xyoo 2000s muaj ib tug 802.11b Wi-nkaus xov tooj cua uas khiav haujlwm hauv 2.4 GHz band. Nyob rau tib lub sij hawm, ib qho tseem ceeb ntawm kev lag luam tes txhawb 802.11a (5 GHz). Thawj thawj ob kab ntsig Wi-nkaus routers tau ua los txhawb cov sib koom tes sib xyaw nrog 802.11a thiab 802.11b neeg.

Pib nrog 802.11n , Wi-nkaus cov qauv pib nrog tib sim dual-band 2.4 GHz thiab 5 GHz kev them nyiaj yug raws li tus txheej txheem qauv.

Cov kev pab ntawm Dual Band Wireless Networking

Los ntawm kev muab cais cais cov cim sib txuas rau txhua tus qhab, dual-band 802.11n thiab 802.11ac routers npaj siab tshaj plaws hauv kev teeb tsa ib lub tsev network. Qee cov cuab yeej hauv tsev yuav tsum tau ua kom muaj kev sib txuas lus zoo dua qub thiab cov teeb liab ntau dua li ntawm 2.4 GHz muaj thaum lwm tus neeg yuav tsum tau txuas ntxiv rau cov kev txuas ntxiv ntawm 5 GHz.

Dual-band routers muaj kev sib txuas uas tsim los rau txhua qhov kev xav tau. Ntau Wi-nkaus lub tsev tes hauj lwm raug kev txom nyem los ntawm kev cuam tshuam kev tsis sib haum vim muaj kev cuam tshuam ntawm 2.4 GHz neeg siv khoom, xws li microwave ncu thiab cov xov tooj cordless, tag nrho cov neeg uas tsuas yog ua haujlwm rau 3 txoj kev tsis sib-overlapping. Lub peev xwm los siv 5 GHz rau ib qho kev pab cuam dual-band yuav pab tiv thaiv cov teeb meem no vim muaj 23 txoj kev tsis sibtshuam uas siv tau.

Dual-band routers kuj sib txuas nrog Multiple-In Multiple-Out (MIMO) xov tooj cua. Kev sib xyaw ntawm ntau lub xov tooj cua ntawm ib qho khoom ua ke nrog kev txhawb nqa ob-qhab no muaj kev ua siab dua rau kev sib tham hauv tsev tshaj li cov qhab-nees band ib zaug.

Piv txwv ntawm Dual Band Wireless Devices

Tsis tas ua ib co routers muab dual-band wireless tiam sis kuj Wi-nkaus network adapters thiab tes.

Dual Band Wireless Routers

TP-LINK Archer C7 AC1750 Dual Band Wireless AC Gigabit Router muaj 450 Mbps ntawm 2.4 GHz thiab 1300 Mbps ntawm 5 GHz, thiab raws li IP-based bandwidth tswj kom koj saib xyuas cov bandwidth ntawm tag nrho cov khoom txuas nrog koj tus router.

Tus NETGEAR N750 Dual Band Wi-Fi Gigabit Router yog rau cov tsev nruab nrab-loj thiab tseem tuaj nrog ib tug genie app ces koj tuaj yeem khaws tabs hauv koj lub network thiab tuaj yeem pab daws teeb meem yog xav tau kho.

Dual Band Wi-Fi Adapters

Dual-band Wi-Fi network adapters muaj 2.4 gHz thiab 5 GHz wireless radios zoo li dual-band routers.

Nyob rau thaum nruab hnub ntawm Wi-nkaus, qee lub laptop Wi-nkaus adapters txhawb cov kev sib txuas lus 802.11a thiab 802.11b / g kom ib tug neeg txuas tau lawv lub computer mus rau cov lag luam tes thaum ua haujlwm hnub thiab tsev tes haujlwm hmo ntuj thiab hnub so. Newer 802.11n thiab 802.11ac adapters tuaj yeem tsim kho kom siv band (tab sis tsis yog ob leeg tib lub sijhawm).

Ib qho piv txwv ntawm ib tug dual band gigabit Wi-nkaus network adapter yog lub NETGEAR AC1200 WiFi USB Adapter.

Dual Tes Tes

Ib yam li cov khoom siv kab sib txuas wireless-network, qee tus xovtooj ntawm tes kuj siv ob los yog ntau tshaj rau kev sib txuas lus ntawm cov xov tooj ntawm tes sib txuas ntawm Wi-nkaus. Dual-band xov tooj tau pib tsim los txhawb 3G GPRS los yog EDGE cov ntaub ntawv kev pab cuam ntawm 0.85 GHz, 0.9 GHz los yog 1.9 GHz xov tooj cua frequencies.

Tes tej zaum kuj txhawb cov tri-band (peb) los yog quad-band (plaub) ntau tshaj plaws ntawm cov xov tooj kom muaj kev sib txig sib luag nrog ntau hom xov tooj, pab tau thaum roaming los yog mus ncig.

Cov xov tooj ntawm tes hloov qhov nruab nrab ntawm kev sib tw, tiam sis tsis pab txhawb kev sib txig sib txuas ua ke.
