Nrog smartphones, ntsiav tshuaj, thiab laptops noj tshaj li lub ntiaj teb, lub sij hawm "wireless" tau ua ib feem ntawm peb cov niaj hnub vernacular. Hauv kev yooj yim tshaj plaws thiab pom tseeb, "wireless" hais txog kev sib txuas lus uas tsis xa xov los yog cov cables, tab sis nyob rau hauv lub tswv yim no yog siv ntau lub sij hawm wireless, los ntawm tes hauj lwm ntawm tes mus rau hauv zos Wi-nkaus tes hauj lwm.
"Wireless" yog ib lub sijhawm ntev uas duav txhua hom kev lag luam thiab cov khoom siv uas xa cov ntaub ntawv tshaj tawm ntawm huab cua es tsis dhau xov tooj, nrog rau kev sib txuas lus ntawm tes, sib txuas ntawm cov computers nrog wireless adapters thiab wireless computer accessories.
Wireless communications mus ncig ntawm huab cua ntawm electromagnetic tsis xws li xov tooj cua frequencies, infrared thiab satellite. Lub FCC tswj cov xov tooj cua ntau zaus rau hauv cov qauv no kom nws tsis tuaj yeem tau txais neeg coob heev thiab saib xyuas kom cov wireless thiab cov kev pabcuam yuav khiav haujlwm zoo.
Lus Cim: Wireless kuj txhais tau tias cov cuab yeej thim lub iPad siv wirelessly tiam sis feem ntau, wireless tsuas txhais tau hais tias tsis muaj cov cords koom nrog cov ntaub ntawv hloov tsheb.
Piv txwv ntawm Wireless Devices
Thaum ib tug neeg hais lo lus "wireless," lawv muaj peev xwm sib tham txog ntau yam khoom (FCC tswj los yog tsis) uas tsis muaj xov xaim. Cov xov tooj Cordless yog cov wireless nruab, xws li cov chaw taws teeb ntawm TV, cov xov tooj cua thiab GPS.
Lwm cov qauv ntawm cov wireless xws li xov tooj ntawm tes, PDAs, wireless nas, keyboards wireless, wireless routers , wireless network cards, thiab zoo nkauj npaum li txhua yam uas tsis siv xov hlau xa xov.
Wireless chargers yog lwm hom wireless ntaus ntawv. Txawm tias tsis muaj cov ntaub ntawv xa mus los ntawm lub wireless charger, nws nrog lwm cov cuab yeej (xws li ib lub xov tooj) uas tsis siv xov hlau.
Wireless Networking thiab Wi-nkaus
Networking technologies uas txuas ntau lub computer thiab cov cuab yeej ua ke tsis muaj xov tooj cua (zoo li hauv wireless network thaj tsam network ) kuj poob rau hauv lub vas sab. Feem ntau, tsis yog hais txog qhov "wireless" rau cov technologies no xwb, lub ntsiab lus yuav siv Wi-Fi (uas yog trademarked los ntawm Wi-Fi Alliance).
WI-Fi npog cov thev naus laus zis uas yog siv 802.11 cov qauv , xws li 802.11g lossis 802.11ac network cards thiab cov kab khiav haujlwm wireless.
Koj tuaj yeem siv Wi-nkaus luam tawm wirelessly li koj network, txuas mus rau lwm lub tshuab computer hauv koj lub network, thiab, thaum koj tsis muaj Wi-nkaus muaj, qhib koj lub xov tooj mus rau qhov chaw nres tsheb Wi-nkaus hotspot rau koj khoos phis tawj thiab lwm yam khoom, siv koj cov ntaub ntawv xov tooj rau kev siv internet.
Ntsis: Paub ntau ntxiv txog qhov sib txawv ntawm cellular wireless cov ntaub ntawv thiab siv Wi-nkaus rau Internet-on-the-go.
Bluetooth yog lwm lub tshuab siv wireless uas koj tau paub dua. Yog hais tias koj cov khoom siv ze txaus ua ke thiab txhawb Bluetooth, koj tuaj yeem txuas lawv mus muab cov ntaub ntawv tsis muaj xov xwm. Cov khoom siv no yog xws li koj lub laptop, xov tooj, tshuab luam ntawv, nas, keyboards, tes taw dawb thiab "smart devices" (xws li lub teeb qij thiab chav dej siv).
Wireless Kev lag luam
"Wireless" ntawm nws tus kheej yog feem ntau yog siv los xa cov khoom siv thiab cov kev pab cuam los ntawm kev lag luam hauv xov tooj ntawm tes. CTIA, "Wireless Association", piv txwv li, yog muaj cov wireless nqa khoom (xws li Verizon, AT & T, T-Mobile, thiab Sprint), xov tooj ntawm tes manufacturers xws li Motorola thiab Samsung thiab lwm tus hauv lub xov tooj txawb xov tooj. Cov kev cai sib txawv hauv cellular (cellular) thiab xov tooj qauv muaj xws li CDMA , GSM , EV-Ua, 3G , 4G , thiab 5G .
Lub sij hawm "wireless internet" feem ntau yog hais txog cov ntaub ntawv cellular, tab sis cov kab lus kuj txhais tau tias cov ntaub ntawv siv ntawm satellite.
