Txhua Yam Koj Yuav Tsum Paub Txog Wireless Networking Technologies
Kev sib txuas lus siv wireless (Wireless communication technology) yog ib lub vib thim niaj hnub siv rau cov kab lis kev cai wired. Qhov twg nyob ntawm qhov chaw wired vam khom cov cables kom txuas tau cov cuab yeej siv ua ke, wireless networks khi wireless technologies.
Wireless technologies yog dav siv nyob rau hauv ob lub tsev thiab lag luam computer network, rau ntau yam kev siv.
Thaum muaj ntau ntau cov kev pab cuam rau wireless technologies, kuj muaj qee cov kev tsis zoo los paub txog.
Hom Wireless Network Technologies
Muaj ntau cov technologies tau tsim los txhawb kev sib tshuam hauv kev sib tham hauv ntau qhov kev sib tw.
Mainstream wireless technologies muaj xws li:
- Wi-nkaus , tshwj xeeb tshaj yog nyob rau hauv cov tuam txhab hauv tsev thiab raws li lub tshuab wireless hotspot
- Bluetooth , rau cov ntawv qis dua thiab kos npe
- 4G thiab 3G cellular internet
- Wireless home automation cov qauv zoo ib yam li ZigBee thiab Z-Wave
Lwm cov technologies tseem nyob hauv kev tsim kho, tiam sis yuav ua rau lub luag haujlwm hauv wireless networks ntawm lub neej yav tom ntej, muaj xws li 5G ntawm cov xov tooj ntawm tes thiab cov pom kev sib pom ntawm Li-Li .
Pros thiab Cons kev siv Wireless Over Wired
Wireless lub computer cov kev pabcuam muaj ntau qhov kev zoo tshaj rau cov kev sib tham hauv wired tab sis tsis yog tsis muaj nqis.
Thawj thiab feem ntau pom, zoo dua ntawm kev siv wireless technology yog qhov kev lag luam loj heev (kev txav mus los thiab kev ywj pheej ntawm kev txav chaw). Tsuas tsis pub wireless ua rau koj siv cov khoom siv tsis txhim kho rau phab ntsa, lawv kuj tshem tawm cov kab hluav taws xob uas tsis muaj kev cuam tshuam nrog rau cov kab hauv wired.
Disadvantages ntawm wireless muaj kev txhawj xeeb ntxiv txog kev ruaj ntseg . Tsis yog koj cov cuab yeej tsuas kov tau koj lub cev nrog rau kev siv lub cev, lawv tuaj yeem raug ntaus los ntawm chav tsev hackers los sis qee zaus txawm tias cov vaj tse nyob ntawm qhov chaw nkag. Lwm downside los siv wireless technologies yog lub zog muaj zog rau xov tooj cua cuam vim huab cua, lwm yam wireless, lossis obstructions zoo li cov phab ntsa.
Qhov tseeb, muaj ob peb yam tseem ceeb los xav txog thaum sib piv cov kab wired thiab wireless networks , xws li tus nqi, kev ua haujlwm, thiab kev cia siab.
Wireless Internet Service
Cov ntaub ntawv ntawm kev lag luam hauv internet cuam tshuam rau cov xov tooj, kab hluav taws xob, thiab cov kab mob fiber ntau . Thaum lub hauv paus tseemceeb hauv internet tseem nyob ntawm wired, ob peb lwm yam siv internet technology siv wireless los txuas cov tsev thiab cov lag luam.
Muaj, piv txwv li, cov kev pabcuam wireless hauv internet xws li cov pej xeem hauv Wi-nkaus rau kev siv wireless thaum koj nyob tsis nyob hauv tsev, wireless wireless broadband rau hauv tsev internet siv, satellite internet , thiab lwm tus.
Lwm Cov Ntaub Ntawv ntawm Wireless
Qhov tshwm sim ntawm lub tswv yim ntawm Internet ntawm Yam (IoT) yog qhov uas peb pom qhov sib xyaw ua ke nyob rau hauv ib qho chaw uas tsis siv ua ntej.
Tsuas yog los ntawm tsev sib txuas, lub sijhawm , cov tub yees , cov tsheb, thiab ntau lwm yam khoom siv - qee zaus txawm tias cov ris tsho - yuav tsum muaj kev sib txuas nrog kev sib txuas lus wireless. Vim tias qhov ntawm wireless technology, tag nrho cov ntawm cov cuab yeej no yuav ua khub ua ke rau txoj kev sib koom seamless nrog txhua lwm yam.
Piv txwv, koj lub xov tooj tuaj yeem ua koj lub ntsuas sov thiab txias kom kho tau qhov kub ntawm koj lub tsev thaum koj tawm mus, koj cov teeb ntse ntse tuaj yeem tig thaum koj tuaj txog hauv tsev, thiab koj tus npliag ntse tuaj yeem khaws tabs ntawm koj qhov kev poob phaus.
Wireless Network Hardware
Txhim kho lub network ua lag luam yuav tsum muaj qee hom computer khoom siv . Portable devices zoo li xov tooj cua thiab ntsiav tshuaj feature built-in wireless radios. Wireless broadband routers zog ntau lub tsev tes hauj lwm. Lwm yam khoom siv muaj xws li sab nraud adapters thiab cov stretchers.
Wireless khoom siv cuab yeej ua lag luam yuav ua nyuaj. Cov neeg tau txais kev pom txog cov npe nrov nrov ntawm cov xov tooj nrov nrov thiab lwm yam khoom siv hauv tsev, tab sis coob tus tsis paub tias muaj pes tsawg lub nrog lawv thiab muaj pes tsawg tus neeg muag khoom ua rau lawv.
Cas Wireless Cov Haujlwm
Wireless technologies ntiav cov xov tooj cua tsis muaj xov tooj cua thiab / los yog microwaves kom muaj kev sib txuas lus sib txawv ntawm cov computers. Hos muaj ntau yam lus qhia txog kev sib sim wireless xws li Wi-nkaus feem ntau tsis yog qhov tseem ceeb rau kev nkag siab, kev paub txog kev qhia txog Wi-nkaus tuaj yeem pab tau zoo thaum teeb tsa lub network thiab daws teeb meem.
Wireless tech peb paub niaj hnub no muaj nws cov keeb kwm nyob rau hauv kev tshawb fawb mus rov qab ntau xyoo. Nikola Tesla pioneered wireless hluav taws xob teeb pom kev zoo thiab lub zog xa mus , piv txwv - cov chaw txuas ntxiv mus rau thaj tsam ntawm kev kawm niaj hnub no rau cov kev siv li wireless charging.
