Wireless access point (APs lossis WAPs) yog cov khoom siv sib txuas uas tso cai rau Wi-nkaus cov cuab yeej txuas mus rau ib lub network. Lawv tsim cov wireless hauv cheeb tsam hauv cheeb tsam network (WLANs).
Ib qho chaw nkag tau ua lub hauv nruab nrab transmitter thiab txais cov xov tooj cua wireless. Mainstream wireless APs txhawb Wi-Fi thiab siv nyob rau hauv tsev, pej xeem internet hotspots, thiab kev lag luam tes hauj lwm kom haum raws li wireless mobile pab kiag li lawm. Qhov chaw nkag tau tuaj yeem muab tso rau hauv ib lub router lossis ib lub router stand-alone.
WAP siv rau dab tsi?
Cov ntsiab lus nkag-ib leeg yog cov khoom siv lub cev me me uas zoo ib yam li lub tsev broadband routers. Wireless routers siv rau kev sib tham hauv tsev muaj cov ntsiab lus nkag mus rau hauv cov khoom siv kho vajtse thiab ua haujlwm nrog cov AP nyob ib leeg. Thaum koj siv lub ntsiav tshuaj lossis lub khoos phis tawj mus online, lub cuab yeej nkag mus los ntawm qhov chaw nkag, xws li kho vajtse lossis built-in, nkag mus rau hauv is taws nem yam tsis tau txuas ntawm cable.
Ntau tus neeg muag khoom tseem ceeb ntawm cov neeg siv khoom siv Wi-nkaus tsim cov ntsiab lus nkag, uas tso cai rau cov lag luam muab kev sib txuas wireless nyob qhov twg lawv tuaj yeem khiav Ethernet cable los ntawm qhov chaw nkag mus rau lub router txuas. AP kho vajtse muaj xov tooj cua transceivers, kav hlau txais xov, thiab ntaus ntawv firmware.
Wi-Fi hotspots feem ntau xa ib lossis ntau dua wireless APs los txhawb thaj chaw Wi-Fi. Kev lag luam tes hauj lwm kuj feem ntau nruab APs thoob plaws hauv lawv qhov chaw ua haujlwm. Thaum lub tsev feem ntau xav tau ib lub router nkaus xwb nrog rau qhov chaw nkag tau tsim los npog qhov chaw ntawm lub cev, cov lag luam feem ntau siv ntau. Kev txiav txim siab qhov chaw zoo tshaj plaws rau kev nkag mus rau qhov chaw teeb tsa tuaj yeem nyuaj txawm tias cov kws tshaj lij network vim tias xav tau los npog qhov chaw sib npaug nrog lub teeb liab txhim khu kev qha.
Siv Wi-Fi Access Points
Yog tias lub router uas twb muaj lawm tsis haum rau cov khoom siv wireless, uas tsis tshua muaj, koj tuaj yeem nthuav tawm lub network los ntawm kev ntxiv cov khoom siv wireless AP rau lub network es tsis txhob ntxiv lub router thib ob. Cov lag luam tuaj yeem nruab ib pawg AP los npog lub tsev ua haujlwm. Cov ntsiab lus nkag tau ua rau Wi-Fi infrastructure hom kev sib tham.
Txawm hais tias kev sib txuas ntawm Wi-Fi tsis tas yuav tsum siv APs, lawv ua rau Wi-Fi tes hauj lwm los ntsuas kom loj dua thiab cov neeg siv khoom. Cov ntsiab lus nkag niaj hnub no txhawb nqa txog 255 tus neeg siv khoom, thaum cov laus txhawb nqa tsuas yog 20. APs kuj tseem muaj peev xwm txuas ntxiv uas ua rau lub network Wi-Fi hauv zos txuas mus rau lwm lub xov tooj sib txuas.
History of Access Points
Thawj cov ntsiab lus nkag wireless tau ua tiav Wi-Fi. Proxim Corporation (tus txheeb ze nyob deb ntawm Proxim Wireless) tau tsim thawj cov cuab yeej zoo li no, muaj npe RangeLAN2, hauv xyoo 1994. Cov ntsiab lus nkag tau txais txiaj ntsig tau txais txiaj ntsig sai tom qab thawj cov khoom lag luam Wi-Fi tau tshwm sim thaum xyoo 1990s.
Thaum hu ua WAP cov cuab yeej hauv xyoo dhau los, kev lag luam maj mam pib siv lub sijhawm AP es tsis yog WAP xa mus rau lawv (ib feem, kom tsis txhob muaj kev tsis sib haum xeeb nrog Wireless Application Protocol), txawm hais tias qee qhov APs yog cov khoom siv xaim.
Nyob rau xyoo tas los no, cov kws pab tswv yim hauv tsev ntse tau siv dav. Cov no suav nrog Google Tsev thiab Amazon Alexa, uas haum rau hauv wireless network zoo li khoos phis tawj, cov khoom siv mobile, tshuab luam ntawv, thiab lwm yam khoom siv los ntawm kev sib txuas wireless mus rau qhov chaw nkag. Lawv ua kom lub suab sib cuam tshuam nrog Is Taws Nem thiab tswj cov cuab yeej siv hauv tsev, suav nrog lub teeb, ntsuas kub, cov khoom siv hluav taws xob, TV, thiab lwm yam, thoob plaws hauv Wi-Fi network uas qhov chaw nkag tau qhib.
