Broadband routers yog tsim los kom yooj yim hauv kev teeb tsa hauv tsev, tshwj xeeb tshaj yog rau cov tsev uas muaj kev pabcuam hauv internet ceev. Dhau li ua kom nws ua tau rau tag nrho cov khoom siv hluav taws xob hauv tsev los sib qhia kev sib txuas hauv internet, broadband routers kuj tseem ua rau kev sib faib cov ntaub ntawv, tshuab luam ntawv, thiab lwm yam kev pab cuam ntawm cov khoos phis tawj hauv tsev thiab lwm yam khoom siv hluav taws xob.
A broadband router siv tus qauv Ethernet rau kev sib txuas nrog. Ib txwm broadband routers yuav tsum tau Ethernet cables uas khiav ntawm lub router, lub broadband modem, thiab txhua lub computer ntawm lub tsev network. Tshiab broadband routers muaj ib tug wired kev twb kev txuas rau hauv internet modem. Lawv txuas nrog cov khoom siv hauv tsev wirelessly siv cov qauv Wi-Fi.
Ntau ntau hom routers muaj, thiab txhua tus ua tau raws li tus qauv tshwj xeeb. Cov routers uas siv cov qauv tam sim no feem ntau muaj nyob ntawm tus nqi siab dua li cov qauv qub, tab sis lawv suav nrog cov yam ntxwv zoo dua. Tus qauv tam sim no yog 802.11ac. Nws tau ua ntej los ntawm 802.11n thiab - txawm tias ua ntej - 802.11g. Tag nrho cov qauv no tseem muaj nyob hauv routers, txawm hais tias cov laus muaj kev txwv.
802.11ac Routers
802.11ac yog tus qauv Wi-nkaus tshiab tshaj plaws. Txhua 802.11ac routers muaj cov cuab yeej tshiab thiab software dua li kev siv yav dhau los thiab zoo meej rau cov tsev nruab nrab mus rau loj qhov ceev thiab kev ntseeg siab yog qhov tseem ceeb.
Ib 802.11ac router siv dual-band wireless thev naus laus zis thiab ua haujlwm ntawm 5 GHz band, tso cai rau 1 Gb / s throughput, lossis ib qho kev sib txuas ntawm tsawg kawg 500 Mb / s ntawm 2.4 GHz. Qhov ceev no zoo tagnrho rau kev ua si, HD media streaming, thiab lwm yam kev xav tau hnyav bandwidth.
Tus qauv no tau txais cov thev naus laus zis hauv 802.11n tab sis txuas ntxiv lub peev xwm los ntawm kev tso cai rau RF bandwidth kom dav li 160 MHz thiab txhawb nqa txog yim ntau qhov kev tawm tswv yim-ntau-tso tawm (MIMO) ntws thiab mus txog plaub downlink multiuser MIMO cov neeg siv khoom.
Lub 802.11ac thev naus laus zis yog rov qab sib xws nrog 802.11b, 802.11g, thiab 802.11n kho vajtse, txhais tau hais tias thaum lub 802.11ac router ua haujlwm nrog cov khoom siv kho vajtse uas txhawb nqa 802.11ac tus qauv, nws kuj tseem muab kev nkag mus rau network rau cov khoom siv uas tsuas yog txhawb 802.11b/g/n.
802.11n Routers
IEEE 802.11n, feem ntau hu ua 802.11n lossis Wireless N), hloov cov thev naus laus zis 802.11a / b / g thiab nce cov ntaub ntawv ntau dua li cov qauv siv ntau lub kav hlau txais xov, ua tiav cov nqi ntawm 54 Mb / s nce. mus txog 600 Mb/s, nyob ntawm seb muaj pes tsawg lub xov tooj cua hauv lub cuab yeej.
802.11n routers siv plaub qhov kwj ntawm 40 MHz channel thiab tuaj yeem siv rau ntawm 2.4 GHz lossis 5 GHz zaus band.
Cov routers no rov qab tau tshaj 802.11g / b / a routers.
802.11g Routers
Tus qauv 802.11g yog Wi-Fi thev naus laus zis qub, yog li cov routers no feem ntau pheej yig. Ib qho 802.11g router yog qhov zoo rau cov tsev uas qhov ceev tshaj plaws tsis tseem ceeb.
Ib 802.11g router ua haujlwm ntawm 2.4 GHz band thiab txhawb nqa tus nqi siab tshaj ntawm 54 Mb / s, tab sis feem ntau muaj txog 22 Mb / s qhov nruab nrab ntawm kev xa tawm. Cov kev ceev no tsuas yog zoo rau qhov yooj yim hauv internet browsing thiab standard-txhais tawm xov xwm streaming.
tus qauv no tau ua tiav nrog cov laus 802.11b kho vajtse, tab sis vim yog qhov kev txhawb nqa qub txeeg qub teg, qhov kev nkag tau raug txo los ntawm 20 feem pua thaum piv rau 802.11a.
