Hauv kev nkag siab yooj yim tshaj plaws, wireless hais txog kev sib txuas lus xa mus yam tsis muaj xov hlau lossis cables. Txawm li cas los xij, lo lus yuav xa mus rau ntau yam thev naus laus zis thiab nruab nrab, los ntawm cov xov tooj ntawm tes mus rau Bluetooth li mus rau hauv zos Wi-Fi tes hauj lwm.

Wireless txhais li cas?

Wireless yog lub ntsiab lus dav dav uas suav nrog txhua hom thev naus laus zis thiab cov khoom siv uas xa cov ntaub ntawv hla huab cua ntau dua li ntawm cov xov hlau, suav nrog kev sib txuas lus ntawm tes, kev sib txuas ntawm cov khoos phis tawj nrog wireless adapters, thiab wireless computer accessories.

Kev sib txuas lus wireless hla huab cua los ntawm electromagnetic nthwv dej. FCC tswj hwm cov xov tooj cua zaus hauv qhov spectrum no, xyuas kom lawv tsis txhob muaj neeg coob coob thiab cov khoom siv wireless thiab cov kev pabcuam ua haujlwm tau ntseeg tau.

Piv txwv ntawm Wireless Devices

Cordless xov tooj yog cov khoom siv wireless, xws li TV chaw taws teeb tswj, xov tooj cua, thiab GPS systems. Lwm yam khoom siv wireless muaj xws li xov tooj, ntsiav tshuaj, nas Bluetooth thiab cov keyboards, wireless routers, thiab feem ntau cov khoom siv uas tsis siv cov xov hlau los xa cov ntaub ntawv.

Wireless chargers yog lwm yam khoom siv wireless. Txawm hais tias tsis muaj cov ntaub ntawv xa los ntawm lub wireless charger, nws cuam tshuam nrog lwm lub cuab yeej (xws li lub xov tooj) yam tsis siv cov xov hlau.

Wireless Networking thiab Wi-Fi

Networking thev naus laus zis uas txuas ntau lub khoos phis tawj thiab cov khoom siv yam tsis muaj xov hlau, xws li lub wireless hauv cheeb tsam network (WLAN), kuj poob rau hauv lub kaus wireless. Feem ntau, cov khoom siv no raug xa mus los ntawm kev ntes-txhua lub sijhawm "Wi-Fi," uas yog cov cim lag luam los ntawm Wi-Fi Alliance.

Wi-Fi npog cov thev naus laus zis uas suav nrog 802.11 tus qauv, xws li 802.11g lossis 802.11ac network phaib thiab wireless routers.

Koj tuaj yeem siv Wi-Fi luam tawm wirelessly hauv tsev lossis chaw ua haujlwm network, txuas ncaj qha rau lwm lub khoos phis tawj hauv koj lub network, thiab tig koj lub xov tooj mus rau hauv lub portable Wi-Fi hotspot rau lwm yam khoom siv.

Bluetooth yog lwm lub tshuab wireless uas koj tau paub txog. Yog tias koj cov khoom siv ze txaus ua ke thiab txhawb nqa Bluetooth, lawv tuaj yeem txuas rau xa cov ntaub ntawv yam tsis muaj xov hlau. Cov khoom siv no yuav suav nrog koj lub laptop, xov tooj, tshuab luam ntawv, nas, keyboard, hands-free headsets, thiab smart devices.

Kev lag luam wireless

Wireless ntawm nws tus kheej feem ntau yog siv los xa mus rau cov khoom lag luam thiab kev pabcuam los ntawm kev lag luam xov tooj ntawm tes. CTIA, lub koom haum Wireless, piv txwv li, muaj xws li cov neeg nqa khoom wireless, xws li Verizon, AT&T, T-Mobile, thiab Sprint, thiab cov tuam txhab xov tooj ntawm tes xws li LG thiab Samsung. Cov txheej txheem wireless sib txawv thiab cov qauv xov tooj suav nrog CDMA, GSM, EV-DO, 3G, 4G, thiab 5G.

Lo lus wireless internet feem ntau yog hais txog cov ntaub ntawv xov tooj ntawm tes, txawm hais tias cov kab lus tseem tuaj yeem txhais tau tias cov ntaub ntawv nkag los ntawm satellite.
