WiFi waa halbeeg caalami ah oo Wireless local area (WLAN), magaca buuxa Wireless Fidelity, sidoo kale loo yaqaan IEEE802.11b standard. WiFi asal ahaan waxay ku salaysan tahay IEEE802.11 borotokool, oo la daabacay 1997, lakabka WLAN MAC qeexan iyo heerarka lakabka jirka. Iyadoo la raacayo borotokoolka 802.11, noocyo badan ayaa la soo bandhigay, kuwa ugu caansan waa IEEE802.11a, IEEE802.11b, IEEE802.11g, iyo IEEE802.11n.
Halabuurka nidaamka WiFi:
WiFi waa isticmaalka tignoolajiyada isgaarsiinta wireless si loogu xiro aaladaha kumbuyuutarka
Astaamaha muhiimka ah ee WiFi LAN: ha isticmaalin fiilooyinka isgaadhsiinta si ay ugu xidhaan kombayutarada shabakada
Shabakadda topology:
WiFi waxaa lagu xidhi karaa iyada oo loo marayo shabakado kala duwan oo topologies ah, iyo helitaankeeda iyo shabakadeeda gelitaanka sidoo kale waxay leedahay shuruudo iyo tallaabooyin u gaar ah. Shabakadaha wireless-ka ee WiFi waxaa ka mid ah laba nooc oo topology ah: Kaabayaasha dhaqaalaha iyo Ad-hoc.
Laba fikradood oo aasaasi ah oo muhiim ah:
Saldhigga (STA): Qaybta aasaasiga ah ee shabakadda, terminal kasta oo ku xiran shabakadda wireless-ka (sida laptops, PDAs iyo aaladaha kale ee isticmaalaha ee la isku xiri karo), waxaa loogu yeeri karaa goob. Goobta Helitaanka Wireless (AP): Abuuraha shabakadda wireless-ka iyo noodhka dhexe ee shabakadda. Celceliska router-ka wireless-ka ee lagu isticmaalo guriga ama xafiiska wuxuu leeyahay hal AP.
Kor ku xusan waa Shenzhen HDV Phoelectron Technology Ltd. si ay u keenaan macaamiisha oo ku saabsan "WiFI technology dulmarka maqaalka" hordhaca ah, iyo shirkadeena waa wax soo saarka gaarka ah ee saarayaasha network indhaha, alaabta ku lug leh waa.ONUtaxane (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Taxanaha moduleka indhaha (Module fiber optical/Module fiber indhaha ee Ethernet / moduleka indhaha ee SFP),OLTtaxane (OLTqalab /OLT beddelo/ Bisadda indhahaOLT), iwm, waxaa jira tilmaamo kala duwan oo alaabta isgaarsiinta ah oo loogu talagalay baahida xaaladaha kala duwan ee taageerada shabakada, ku soo dhawow inaad la tashato.
