WiFi ndi muyezo wapadziko lonse lapansi wa Wireless Local Area Network (WLAN), dzina lathunthu Wireless Fidelity, womwe umadziwikanso kuti IEEE802.11b muyezo. WiFi poyambilira idakhazikitsidwa pa protocol ya IEEE802.11, yomwe idasindikizidwa mu 1997, yomwe idatanthauzira WLAN MAC wosanjikiza komanso miyezo yapagulu. Kutsatira protocol ya 802.11, mitundu yambiri idayambitsidwa, yodziwika bwino ndi IEEE802.11a, IEEE802.11b, IEEE802.11g, ndi IEEE802.11n.
Kapangidwe ka WiFi system:
WiFi ndikugwiritsa ntchito ukadaulo wolumikizirana opanda zingwe kulumikiza zida zamakompyuta
Makhalidwe ofunikira a WiFi LAN: osagwiritsanso ntchito zingwe zolumikizirana kulumikiza makompyuta ndi netiweki,
Network topology:
WiFi imatha kulumikizidwa kudzera pamitundu yosiyanasiyana yapaintaneti, ndipo kupezeka kwake ndi netiweki yofikira ilinso ndi zofunikira ndi masitepe ake. Maukonde opanda zingwe a WiFi amaphatikizapo mitundu iwiri ya topology: Infrastructure ndi Ad-hoc.
Mfundo ziwiri zofunika:
Station (STA) : Chigawo chofunikira kwambiri cha intaneti, cholumikizira chilichonse cholumikizidwa ndi netiweki yopanda zingwe (monga ma laputopu, PDAs ndi zida zina zogwiritsa ntchito zomwe zitha kulumikizidwa), zitha kutchedwa tsamba. Wireless Access Point (AP) : Wopanga ma netiweki opanda zingwe komanso node yapakati pa netiweki. Wapakati waya opanda zingwe omwe amagwiritsidwa ntchito mnyumba kapena ofesi ali ndi AP imodzi.
Zomwe zili pamwambazi ndi Shenzhen HDV Phoelectron Technology Ltd. kuti ibweretse makasitomala za "WIFI Technology Overview" nkhani yoyambira, ndipo kampani yathu ndiyopanga mwapadera opanga opanga ma netiweki, zomwe zikukhudzidwa ndiONUmndandanda (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Optical module series (optical fiber module/Ethernet optical fiber module / SFP Optical module),OLTmndandanda (OLTzida /OLT kusintha/ mphaka wowonekaOLT), etc., pali specifications zosiyanasiyana za mankhwala kulankhulana kwa zosowa za zochitika zosiyanasiyana thandizo maukonde, kulandiridwa kufunsira.
