Thaum koj thaum kawg tau koj lub tsev network teeb tsa thiab ua haujlwm zoo, tej zaum qhov kawg koj xav ua yog hloov nws. Yog tias koj lub network tsis muaj peev xwm Wireless N, txawm li cas los xij, koj tuaj yeem ploj mus ntawm qhov nrawm dua thiab kev ntseeg tau zoo dua.
Lo lus Wireless N yog hais txog Wi-Fi wireless network khoom siv uas khiav 802.11n xov tooj cua sib txuas lus raws tu qauv.
Cov txiaj ntsig ntawm Wireless N
Wireless N tso cai rau koj hloov cov ntaub ntawv ntawm cov khoom siv sai dua. Piv txwv li, cov khoom qub 802.11g tuaj yeem sib txuas lus hauv lub network ntawm tus qauv tus nqi ntawm 54 Mbps. Wireless N cov khoom txhawb nqa tus qauv ntawm 150 Mbps, kwv yees li peb zaug sai dua, nrog rau kev xaiv rau cov nqi siab dua kuj muaj.
Wireless N thev naus laus zis kuj tseem txhim kho kev tsim cov xov tooj cua thiab kav hlau txais xov ua rau hauv lub network kho vajtse. Lub teeb liab ntau ntawm Wireless N routers feem ntau dhau ntawm cov ntawv qub ntawm Wi-Fi, pab kom ncav cuag tau zoo dua thiab tswj kev sib txuas ntau dua nrog cov cuab yeej txuas ntxiv mus lossis sab nraum zoov. Tsis tas li ntawd, 802.11n tuaj yeem ua haujlwm ntawm cov teeb liab frequencies sab nraum lub band feem ntau siv los ntawm lwm cov khoom siv uas tsis yog-networked, txo qhov muaj feem cuam tshuam ntawm xov tooj cua hauv tsev.
Txawm hais tias Wireless N feem ntau txhim kho qhov ceev ntawm cov yeeb yaj kiab, suab paj nruag thiab lwm yam ntaub ntawv sib koom hauv tsev, nws tsis ua kom nrawm ntawm kev sib txuas ntawm koj lub tsev thiab lwm yam hauv internet. Txawm li cas los xij, cov khoom siv hauv zos xws li Network Attached Storage drives ua haujlwm ntawm qhov siab tshaj plaws ntawm Wi-nkaus network, yog li Wireless N ua haujlwm zoo yog tias koj lub tsev network tso siab rau ntau dua li hauv internet.
Wireless N Txhawb nqa hauv Cov Khoom Siv Khoom Siv
Wireless N iav tau pib tshwm sim ntawm qhov tshwm sim thaum ntxov xyoo 2006, yog li muaj lub sijhawm zoo heev rau cov cuab yeej koj siv tam sim no txhawb nqa nws. Piv txwv li, Apple ntxiv 802.11n rau nws cov xov tooj thiab ntsiav tshuaj pib nrog iPhone 4. Yog tias lub khoos phis tawj, xov tooj lossis lwm yam khoom siv wireless uas koj siv tsis muaj kev txhawb nqa kho vajtse rau 802.11n, koj tsis tuaj yeem tau txais txiaj ntsig ntawm Wireless N ntawm cov cuab yeej tshwj xeeb ntawd. Tshawb xyuas cov ntaub ntawv khoom los txiav txim seb hom WI-Fi koj li kev txhawb nqa li cas.
Devices tuaj yeem txhawb Wireless N hauv ob txoj kev sib txawv. Dual-band Devices tuaj yeem siv 802.11n los sib txuas lus ntawm ob lub xov tooj cua sib txawv - 2.4 GHz thiab 5 GHz, thaum cov khoom siv ib leeg tuaj yeem sib txuas lus ntawm 2.4 GHz. Piv txwv li, iPhone 4 txhawb nqa ib leeg wireless N, thaum lub iPhone 5 txhawb nqa dual-band.
Xaiv lub Wireless N Router
Yog tias koj lub tsev network router tsis txhawb 802.11n, koj cov khoom siv wireless N tsuas tuaj yeem tau txais txiaj ntsig ntawm 802.11n thaum lawv txuas ncaj qha rau ib leeg hauv ad hoc wireless hom. (Lwm yam, lawv poob rov qab rau cov laus 802.11b/g Wi-Fi kev sib txuas lus.) Txawm li cas los xij, feem ntau cov qauv ntawm cov routers hauv tsev muag niaj hnub no suav nrog Wireless N.
Txhua Wireless N routers txhawb nqa dual-band 802.11n. Cov khoom poob rau hauv plaub pawg thawj coj raws li qhov siab tshaj plaws cov ntaub ntawv tus nqi (network bandwidth) lawv txhawb:
- 150 Mbps
- 300 Mbps
- 450 Mbps
- 600 Mbps
Nkag-theem Wireless N routers txhawb nqa 150 Mbps bandwidth nrog ib lub xov tooj cua Wi-Fi thiab ib lub kav hlau txais xov txuas rau chav tsev. Routers uas txhawb nqa cov ntaub ntawv siab dua tau txuas ntxiv ntxiv xov tooj cua thiab kav hlau txais xov rau hauv chav tsev kom tswj tau ntau txoj hauv kev ntawm cov ntaub ntawv sib npaug. 300 Mbps Wireless N routers muaj ob lub xov tooj cua thiab ob lub kav hlau txais xov, thaum 450 thiab 600 Mbps muaj peb thiab plaub ntawm txhua tus, feem.
Thaum nws zoo li muaj laj thawj tias xaiv lub router uas muaj qib siab dua yuav ua rau koj lub network ua haujlwm tau zoo, qhov kev nce qib no tsis tas yuav tsum paub hauv kev xyaum. Rau kev sib txuas hauv tsev kom ua tau zoo ntawm qhov ceev tshaj plaws ntawm kev txhawb nqa router, txhua lub cuab yeej yuav tsum muaj cov xov tooj cua sib xws thiab kav hlau txais xov. Feem ntau cov neeg siv khoom siv niaj hnub no txhawb nqa tsuas yog 150 Mbps lossis qee zaum 300 Mbps kev sib txuas. Yog tias tus nqi sib txawv tseem ceeb, xaiv qhov qis kawg Wireless N router hauv ib qho ntawm ob pawg no ua rau muaj kev nkag siab zoo. Ntawm qhov tod tes, xaiv lub router siab dua tuaj yeem tso cai rau koj lub tsev network kom txhawb nqa cov iav tshiab yav tom ntej.
Teeb tsa Lub Tsev Network nrog Wireless N
txheej txheem ntawm kev teeb tsa Wireless N router yog ze li qub rau lwm hom routers hauv tsev nrog qhov tshwj xeeb tshwj xeeb ntawm kev teeb tsa dual-band wireless. Vim tias 2.4 GHz yog lub wireless band hnyav siv los ntawm cov neeg siv khoom siv, siv 5 GHz band rau txhua yam khoom siv uas txhawb nqa.
txhawm rau teeb tsa 5 GHz kev sib txuas ntawm koj lub network hauv tsev, ua ntej xyuas kom meej tias qhov kev xaiv router rau kev ua haujlwm dual-band tau qhib, feem ntau yog los ntawm lub pob lossis checkbox ntawm ib qho ntawm lub router cov kev tswj xyuas cov ntxaij vab tshaus. Tom qab ntawd qhib lub cuab yeej rau 5 GHz channel ua haujlwm zoo ib yam.
Puas muaj dab tsi zoo dua 802.11n?
Cov tiam tom ntej ntawm Wi-Fi li tom qab 802.11n txhawb kev sib txuas lus tshiab hu ua 802.11ac. Ib yam li Wireless N tau muab kev txhim kho tseem ceeb hauv kev nrawm thiab ntau yam piv rau 802.11g, yog li 802.11ac muab kev txhim kho zoo sib xws saum Wireless N. 802.11ac muaj cov ntaub ntawv theoretical pib ntawm 433 Mbps, tab sis ntau yam khoom tam sim no lossis yav tom ntej txhawb nqa gigabit (1000 Mbps) thiab tus nqi siab dua.
