Bluetooth yog tus qauv uas txuas lub computer peripherals wirelessly rau tus tswv tsev. Feem ntau siv txuas cov neeg hais lus, lub taub hau, cov keyboards, tshuab luam ntawv, thiab lub mloog pob ntseg rau lub xov tooj, ntsiav tshuaj, lossis computer. Wi-Fi yog tus qauv uas tso cai rau kev siv internet wireless rau cov khoom siv hauv cheeb tsam network (LAN). Thaum nyob ntawm modems, Wi-nkaus tes hauj lwm siv wireless routers es tsis txhob siv Ethernet cables los txuas cov khoom siv hauv internet. Peb mus tob tob rau hauv qhov zoo sib xws thiab qhov sib txawv ntawm Bluetooth thiab Wi-Fi.
Kev Tshawb Nrhiav Txhua Yam
- Feem ntau rau kev sib txuas rau ib leeg.
- qis zog, luv dua, thiab qeeb cov ntaub ntawv ceev.
- Ua haujlwm ntawm RF (xov tooj cua zaus) spectrum.
- Feem ntau rau kev txuas cov khoom siv hauv internet.
- Lub zog siab dua, ntau dua, thiab cov ntaub ntawv nrawm dua.
- Ua haujlwm ntawm RF (xov tooj cua zaus) spectrum.
Bluetooth yog ib qho kev sib txuas lus wireless uas tso cai rau ob lub cuab yeej sib txuas lus nrog ib leeg los ntawm xov tooj cua zaus (RF). Nrog Bluetooth, koj tuaj yeem wirelessly tswj tus hais lus los ntawm ib qho app hauv koj lub xov tooj lossis luam cov ntaub ntawv ntawm lub tshuab luam ntawv uas tsis txuas nrog koj lub computer. Bluetooth kuj tseem siv nrog hands-free headsets, wireless navigation systems, thiab tej thaj chaw deb nas thiab keyboards.
A Wi-Fi network yog qhov txuas txuas txuas ntxiv ntawm kev sib txuas ntawm lub modem. Wi-Fi yog cov txheej txheem txuas wireless uas siv los ntawm kev sib txuas lus xws li Ethernet. Nws yuav tsum muaj lub router wireless, dhau los ntawm tag nrho cov khoom siv Wi-nkaus ntawm lub network raug xa mus.
Lo lus Wi-Fi qee zaum siv sib hloov nrog hauv internet. Wi-Fi tsis zoo ib yam li hauv internet. Lub modem txuas rau hauv internet.
Ob leeg Wi-Fi thiab Bluetooth ua haujlwm ntawm lub xov tooj cua zaus, txawm hais tias qhov ntau ntawm Wi-Fi network feem ntau loj dua li kev sib txuas ntawm Bluetooth. Txawm hais tias ntau lub network Wi-Fi siv tib lub 2.4 GHz band li Bluetooth, Wi-Fi siv ntau lub zog.

Speed: Siab zog muab siab dua
-
Slower.
- Cov neeg siv feem ntau tsis tas yuav cov ntaub ntawv ceev ceev heev.
- Nyob.
- Muaj peev xwm hloov cov ntaub ntawv ceev ceev rau cov xov xwm siab bandwidth streaming.
Bluetooth feem ntau qeeb dua thiab muaj bandwidth tsawg dua Wi-Fi. Qhov no yog ib qho ntawm cov laj thawj vim li cas Bluetooth lub suab zoo yog suav tias yog qis dua. Wi-Fi tuaj yeem siv los tshaj tawm cov suab paj nruag zoo, cov ntsiab lus video, thiab lwm cov ntaub ntawv loj.
Bluetooth 4.0 muaj kev nrawm dua li cov qauv siv thev naus laus zis dhau los. Txawm li cas los xij, nws yog capped ntawm 25 Mbps, thiab tus nqi siv tau qis dua qhov ntawd. Wi-Fi network ceev sib txawv nyob ntawm tus txheej txheem, tab sis qhov kev sib txuas qeeb tshaj plaws yog nrawm dua li qhov theoretical txwv ntawm Bluetooth 4.0.
Siv Case: Peripherals vs. Tag Nrho Hauv Tsev Siv Internet
-
Feem ntau yog rau kev txuas cov khoom siv sab nraud xws li hais lus, tshuab luam ntawv, keyboards, thiab lub mloog pob ntseg.
- Kev ua haujlwm luv dua li Wi-Fi.
- Feem ntau rau kev txuas hauv internet.
- Tsim kom muaj wireless LAN (hauv cheeb tsam network) nkag tau los ntawm txhua lub cuab yeej nrog kev nkag mus rau daim ntawv pov thawj.
Bluetooth feem ntau yog siv los txuas ob lub cuab yeej dhau qhov luv luv uas siv lub zog qis. Qhov no ua rau nws zoo tagnrho rau kev xa suab los ntawm lub xov tooj lossis ntsiav tshuaj mus rau lub suab hais lus, lossis rau kev hu xov tooj tsis pub siv hauv tsheb. Bluetooth kuj tseem muab txoj hauv kev yooj yim los mloog suab paj nruag thaum tsav tsheb, ua haujlwm raws li lub zog pabcuam wireless.
Wi-Fi tsis yog siv rau hauv cov xwm txheej no, vim lub hom phiaj tseem ceeb yog los tsim lub network rau lwm yam khoom siv nkag mus rau hauv internet. Raws li, nws muaj txiaj ntsig zoo hauv tsev thiab chaw ua haujlwm ntau dua li hauv tsheb.
Networking: Txhua Txoj Kev mus rau Modem
-
Wirelessly txuas cov neeg hais lus, lub taub hau, cov keyboards, tshuab luam ntawv, thiab lub mloog pob ntseg los tswj cov khoom siv-feem ntau yog lub xov tooj, ntsiav tshuaj, lossis computer.
- Wirelessly txuas ib lub cuab yeej rau lub modem, uas txuas rau hauv internet. Kuj tseem tuaj yeem txuas rau lwm cov khoom siv hauv LAN.
Ob lub xov tooj thiab wireless yuav tsum tau hla dhau los ntawm modem, uas yog qhov tseeb portal rau hauv internet. Tsuav yog lub modem txuas nrog hauv internet, txhua yam khoom siv txuas nrog lub modem yog (lossis muaj peev xwm ua tau) txuas nrog internet.
kev sib txuas Bluetooth tuaj yeem tshwm sim los ntawm Ethernet lossis Wi-Fi kev sib txuas. Kev ua tiav Bluetooth ua ke yuav muaj txog li 30 ko taw. Txawm li cas los xij, nyob rau hauv ntau qhov xwm txheej, qhov kev ua tau zoo yog luv dua. Bluetooth siv lub zog me me sib piv thiab haum rau lub network ntawm tus kheej, lossis PAN. PANs yog siv rau kev sib txuas lus ntawm cov khoom siv ntawm tus kheej thiab sib piv nrog LAN.
A Wi-Fi network yog LAN los ntawm cov khoom siv tuaj yeem txuas mus rau modem thiab, dhau los, internet. Vim li ntawd, nws tuaj yeem siv wireless router los tsim Wi-Fi network yam tsis muaj kev sib txuas hauv internet. Qhov no tso cai rau cov khoom siv hauv lub network sib faib cov ntaub ntawv rau ib leeg, txawm hais tias cov cuab yeej no yuav tsis tuaj yeem txuas rau Is Taws Nem yam tsis muaj modem.
Kev Txiav Txim Kawg
Sib piv Wi-Fi thiab Bluetooth zoo li piv cov txiv apples thiab txiv kab ntxwv. Wi-Fi yog superior rau Bluetooth nyob rau hauv cov nqe lus ntawm ntau yam thiab ceev. Bluetooth tau txais txiaj ntsig rau nws lub zog qis thiab nqaim RF ntau yam, uas Wi-Fi tsis muaj.
Wi-Fi yog tus qauv nyiam los tsim kev sib txuas hauv tsev wireless. Bluetooth yog tus qauv nyiam rau wirelessly txuas lub computer peripherals. Bluetooth tseem muaj ntau ntxiv nyob rau hauv lub taub hau units, hais lus, thiab tsev ua yeeb yam receivers. Nws yog ib qho nyuaj rau xav txog kev sib tw ntau rau ib qho, tab sis qhov ze tshaj plaws yuav yog Wi-Fi Direct.
Wi-Fi Direct yog qhov kev coj ua tshiab dua ntawm tus qauv ntaus ntawv-rau-tus qauv uas Bluetooth tau ua tiav rau ob peb lub xyoo dhau los. Zoo li Bluetooth, Wi-Fi Direct yog tsim los tso cai rau cov khoom siv sib ntsib yam tsis tau teeb tsa lub ad hoc network. Qhov sib txawv loj tshaj plaws ntawm kev sib txuas ntawm ad hoc Wi-Fi thiab Wi-Fi Direct yog qhov tom kawg suav nrog cov cuab yeej tshawb pom. Lwm qhov teeb meem nrog Wi-Fi thiab Wi-Fi Direct yog kev siv hluav taws xob, uas hnyav thiab ib txwm muaj teeb meem nrog cov khoom siv txawb.
