Wireless USB yog hom kev sib txuas lus wireless uas zoo li muaj qhov luv luv thiab ntau ntawm bandwidth. Nws yog feem ntau siv hauv cov nas hauv computer thiab cov keyboards los muab kev yooj yim dua ntawm tus nqi ntawm kev xav tau lub zog sab hauv xws li roj teeb. Wireless USB yog qee zaum luv li 'WUSB' tab sis feem ntau hu ua Certified Wireless USB.
Certified Wireless USB tsis yog lwm lub npe rau Bluetooth vim lawv txawv kev sib txuas lus.
Yuav ua li cas Wireless USB ua haujlwm
Wireless USB ua haujlwm zoo li tus qauv USB (Universal Serial Bus), tab sis tsis muaj tooj liab xaim ua tus txuas nruab nrab. Qhov twg cov teeb liab thiab cov ntaub ntawv yuav nquag tshaj tawm raws li cov xov tooj tooj liab, lub wireless USB adapter (xws li ib feem ntawm tus nas, keyboard, lossis lub mloog pob ntseg) hloov cov teeb liab mus rau hauv xov tooj cua tsis. Feem ntau ntawm wireless USB keyboards ua haujlwm ntawm 2.4 GHz xov tooj cua zaus.
Thaum koj nias tus yuam sij ntawm cov keyboard, lub teeb liab tau tshaj tawm raws li lub xov tooj cua nthwv dej rau tus txais, thaum ntawd txhais cov teeb liab ntawm lub xov tooj cua yoj mus rau cov ntaub ntawv uas lub computer siv tau. Cov ntaub ntawv no raug xa mus rau lub cuab yeej tsav tsheb thiab tom qab ntawd txiav txim siab thiab dhau mus rau lub operating system.
Rau cov dej num uas xav tau kev nkag siab zoo (xws li kev ua si), cov khoom siv wireless qee zaum frowned. Feem ntau yog nyob nruab nrab ntawm 8 thiab 16 milliseconds ntawm lag nrog txhua lub wireless USB ntaus ntawv vim yog 125 Hz pov npav tus nqi uas yog tus qauv hauv USB li.
Ntau yam khoom siv uas siv Wireless USB xav tau lub transceiver me me txhawm rau ua haujlwm nrog koj lub computer. Feem ntau, lub transceiver ntsaws rau hauv USB Hom-A chaw nres nkoj (cov duab plaub) thiab sib txuas lus nrog peripheral li ntawd es tsis yog siv Wi-Fi ua rau hauv koj lub computer.
Types ntawm Wireless USB Devices
Muaj plaub yam tseem ceeb ntawm wireless USB li koj yuav ntsib:
- Wireless nas
- wireless keyboards
- wireless headphones
- Wireless USB Hubs
Wireless headphones ua haujlwm txawv me ntsis ntawm cov nas wireless thiab cov keyboards vim yog hom ntaub ntawv lawv tau xa mus. Thaum cov nas wireless thiab cov keyboards tshaj tawm qhov tseem ceeb ntawm cov ntaub ntawv binary, lossis ib qho ntawm 1s thiab 0s, cov ntaub ntawv suab yog qhov nyuaj thiab yog li xav tau ntau dua los txiav txim siab. Cov no kuj tseem ua haujlwm ntawm 2.4 GHz zaus thiab tso cai txav mus txog 30 ko taw deb ntawm tus txais.
Lwm hom khoom siv yog lub wireless USB hub. Lub wireless USB hub tso cai rau USB cov khoom siv sib qhia thoob plaws hauv lub network. Nws ua qhov no los ntawm kev tsim USB rau Wi-nkaus choj; Hauv lwm lo lus, nws txhais cov teeb liab los ntawm cov khoom siv txuas nrog USB rau hauv lub teeb liab uas txhua yam khoom siv hauv lub network tuaj yeem nyeem tau.
Qhov downside rau kev siv lub wireless USB hub yog tias txhua yam khoom siv txuas nrog lub hub yuav tsum txuas ncaj qha los ntawm USB cable. Lub wireless nam ntawm lub hub tsuas yog hais txog nws lub peev xwm los txuas dhau Wi-Fi.
Muaj lwm hom khoom siv USB, tab sis feem ntau muaj kev siv tshwj xeeb uas tsis siv rau qhov siv nruab nrab. Cov nas, cov keyboards, lub mloog pob ntseg, thiab cov hubs yog cov feem ntau ntsib thiab npog 95% ntawm tag nrho cov khoom siv USB.
Wireless USB txuas nrawm
Qhov kawg nam uas yuav tsum nco ntsoov txog USB yog nws qhov ceev. USB 2.0 yog qhov qub (thiab ntau dua hauv cov khoom qub) hom kev sib txuas. USB 3.0 yog hom tshiab dua uas tau nrawm dua. USB 3.0 tau dhau los ua tus qauv uas feem ntau pom hauv cov khoom siv wireless tshiab.
