I-WiFi ngumgangatho wothungelwano lwengingqi olungenangcingo lwamazwe ngamazwe (WLAN), igama elipheleleyo elithi Wireless Fidelity, ekwaziwa ngokuba yi-IEEE802.11b standard. I-WiFi ekuqaleni yayisekelwe kwi-IEEE802.11 protocol, eyapapashwa ngo-1997, ichaza umaleko we-WLAN MAC kunye nemigangatho yomaleko womzimba. Ukulandela i-802.11 protocol, ezininzi iinguqulelo ziye zaziswa, ezona ziqhelekileyo ziyi-IEEE802.11a, IEEE802.11b, IEEE802.11g, kunye ne-IEEE802.11n.
Ukwakhiwa kwenkqubo yeWiFi:
I-WiFi kukusetyenziswa kweteknoloji yonxibelelwano engenazingcingo ukuqhagamshela izixhobo zekhompyutha
Iimpawu ezibalulekileyo ze-WiFi LAN: awusasebenzisi iintambo zonxibelelwano ukudibanisa iikhompyuter kwinethiwekhi,
Itopology yenethiwekhi:
I-WiFi inokunxibelelana ngee-topology ezahlukeneyo zenethiwekhi, kwaye ukufunyanwa kwayo kunye nokufikelela kwinethiwekhi nayo ineemfuno zayo kunye namanyathelo. Uthungelwano olungenazingcingo lweWiFi lubandakanya iindidi ezimbini zetopology: Infrastructure and Ad-hoc.
Iikhonsepthi ezimbini ezibalulekileyo ezisisiseko:
Isitishi (STA) : Eyona nxalenye isisiseko sothungelwano, yonke i-terminal eqhagamshelwe kwinethiwekhi engenazingcingo (ezifana neelaptops, iiPDAs kunye nezinye izixhobo zabasebenzisi ezinokuxhunywa kwinethiwekhi), zinokubizwa ngokuba yindawo. I-Wireless Access Point (AP) : Umdali wenethiwekhi engenazintambo kunye ne-node ephakathi yenethiwekhi. I-avareji yerutha engenazingcingo esetyenziswa kwikhaya okanye kwiofisi ine-AP enye.
Oku ngasentla yi-Shenzhen HDV Phoelectron Technology Ltd. ukuzisa abathengi malunga nenqaku lentshayelelo elithi "WIFI technology Overview", kwaye inkampani yethu iyimveliso ekhethekileyo yabenzi benethiwekhi yamehlo, iimveliso ezibandakanyekayoI-ONUuthotho (OLT I-ONU/ACI-ONU/CATVI-ONU/GPONI-ONU/XPONI-ONU), uchungechunge lwemodyuli ye-Optical (imodyuli yefiber optical / Ethernet imodyuli yefiber optical / SFP imodyuli yokubona),OLTuthotho (OLTizixhobo /OLT tshintsha/ikati yamehloOLT), njl., kukho iinkcukacha ezahlukeneyo zeemveliso zonxibelelwano kwiimfuno zeemeko ezahlukeneyo zenkxaso yenethiwekhi, wamkelekile ukubonisana.
