Lub sij hawm WAP muaj ob lub ntsiab lus txawv nyob rau hauv lub ntiaj teb ntawm wireless networking. WAP yog ob qho tib si Wireless Access Point thiab Wireless Protocol Protocol .
Cov Ntsiab Lus Kab Ntsig Wireless
Lub wireless point yog ib lub tshuab uas txuas ib lub wireless (feem ntau Wi-Fi ) hauv zos lub network mus rau ib lub network (feem ntau Ethernet ) network.

Daim ntawv thov kev cai Wireless
Wireless Protocol Protocol tau sau tseg los txhawb cov kev xa khoom mus rau cov khoom siv hauv kev tshaj li cov wireless networks. Sab nraud rau qhov tsim ntawm WAP yog pawg pawg raws li OSI qauv . WAP siv ntau qhov kev sib txuas lus tshiab uas ua haujlwm zoo ib yam li tab sis nyias cais nyias ntawm HTTP , TCP , thiab SSL .
WAP muaj cov tswv yim ntawm browsers, servers , URLs , thiab cov qhov rooj txuas rau lub network . WAP browsers tau ua rau cov khoom me me xws li xov tooj ntawm tes, pagers, thiab PDAs. Tsis yog tsim cov ntsiab lus hauv HTML thiab JavaScript, WAP cov neeg tsim khoom siv WML thiab WMLScript. Kev txwv tsis pub dhau ob lub xov tooj ntawm tes thiab ua haujlwm ntawm cov khoom siv, WAP tsuas yog ib qho kev pabcuam me me ntawm lub PC. Cov kev siv xov xwm ntawm cov technologies no yog xov xwm txuag, Tshuag cov quotes, thiab kev xa xov.
Txawm tias muaj pes tsawg tus WAP-enabled devices muaj nyob hauv kev ua lag luam los ntawm 1999 mus txog rau nruab nrab xyoo 2000s, nws tsis ntev ntev rau kev siv tshuab ua dhau los nrog kev siv technology ceev ceev hauv kev sib tham ntawm kev sib tham ntawm tes thiab smartphones.
Tus qauv WAP
Tus qauv WAP muaj tsib txheej hauv ib pawg, txij toj mus rau sab hauv qab: Daim Ntawv Thov, Kev Sib Tham, Kev Sib Tham, Kev Ruaj Ntseg thiab Kev Thauj.
WAP's txheej txheem ntawm txheej txheem (Application Wide) yog qhov chaw Siv Wireless Wireless (WAE). WAE yeej txhawb kev WAP daim ntawv thov kev pab nrog Wireless Markup Language (WML) siv HTML thiab WMLScript siv JavaScript. WAE kuj muaj xws li Wireless Interface Application Interface (WTAI, los yog WTA luv luv) uas muab lub programming rau cov xov tooj rau kev pib sib tham, xa cov ntawv xov xwm, thiab lwm yam kev sib txuas lus.
WAP txoj kev sib ntsib txheej txheem yog Wireless Wireless Protocol (WSP). WSP yog sib npaug rau HTTP rau WAP browsers. WAP siv browsers thiab servers ib yam li lub Vev Xaib, tab sis HTTP tsis yog qhov kev xaiv rau WAP vim nws txoj kev tsis sib haum xeeb ntawm tus xaim. WSP txuag cov khoom siv bandwidth precious hauv kev sib txuas; hauv particular, WSP ua haujlwm nrog compact binary cov ntaub ntawv uas HTTP ua hauj lwm mas nrog cov ntaub ntawv luam tawm.
Wireless Transaction Protocol (WTP) muab cov kev pab cuam-sib pab rau ob qho tag nrho kev tso siab thiab tsis sib haum thauj. Nws txwv tsis pub cov ntawv luam ntawm cov pob ntawv tsis tau txais los ntawm qhov chaw nres tsheb, thiab nws txhawb kev tuav tswj, yog tias tsim nyog, thaum muaj cov ntawv ntim khoom poob. Hauv no hwm, WTP zoo ib yam li TCP. Txawm li cas los, WTP kuj sib txawv ntawm TCP. WTP yog qhov tseem ceeb ntawm txoj kev sib nkag siab TCP uas sib zog ntxiv qee qhov kev ua tau zoo hauv lub network.
Wireless Transaction Txheej Security (WTLS) muab authentication thiab encryption functionality analogous rau Secure Sockets txheej (SSL) hauv Web networking. Zoo li SSL, WTLS yog xaiv tau thiab siv tsuas yog thaum lub ntsiab lus neeg rau kev ua yuam kev.
Wireless Datagram Protocol (WDP) siv cov txheej txheem sib npaug rau cov kev sib txuas lus hauv kev sib txuas lus tsawg dua; nws ua haujlwm zoo li UDP. WDP yog txheej hauv qab ntawm WAP pawg, tab sis nws tsis siv lub cev los yog cov ntaub ntawv txuas kev muaj peev xwm. Txhim ua kom tiav network, WAP pawg yuav tsum tau ua raws li qee qhov kev sib txuas lus tsis tshua muaj pes tsawg tus tsis muaj kev cuam tshuam ntawm cov qauv. Cov interfaces, hu ua cov kev pabcuam uas tau txais lossis cov neeg tuaj yeem , tuaj yeem yog IP-based lossis tsis yog IP-based.
