I-WiFi indinganiso yenethiwekhi yendawo engenantambo yamazwe ngamazwe (WLAN), igama eligcwele elithi Wireless Fidelity, eyaziwa nangokuthi i-IEEE802.11b standard. I-WiFi ekuqaleni yayisekelwe kuphrothokholi ye-IEEE802.11, eyanyatheliswa ngo-1997, yachaza ungqimba lwe-WLAN MAC namazinga ongqimba abonakalayo. Ngokulandela umthetho olandelwayo we-802.11, izinguqulo eziningi zethuliwe, ezijwayelekile kakhulu i-IEEE802.11a, IEEE802.11b, IEEE802.11g, kanye ne-IEEE802.11n.
Ukwakhiwa kwesistimu ye-WiFi:
I-WiFi ukusetshenziswa kobuchwepheshe bokuxhumana obungenantambo ukuxhuma amadivaysi ekhompyutha
Izici ezibalulekile ze-WiFi LAN: ayisasebenzisi izintambo zokuxhumana ukuxhuma amakhompyutha kunethiwekhi,
I-topology yenethiwekhi:
I-WiFi ingaxhunywa kunethiwekhi ngokusebenzisa ama-topology enethiwekhi ahlukene, futhi inethiwekhi yokutholwa kwayo nokufinyelela nayo inezidingo nezinyathelo zayo. Amanethiwekhi angenantambo e-WiFi afaka izinhlobo ezimbili ze-topology: Ingqalasizinda kanye ne-Ad-hoc.
Imiqondo emibili ebalulekile eyisisekelo:
Isiteshi (STA) : Ingxenye eyisisekelo kakhulu yenethiwekhi, yonke itheminali exhunywe kunethiwekhi engenantambo (njengamakhompyutha aphathekayo, ama-PDA namanye amadivaysi omsebenzisi angaxhunywa kunethiwekhi), ingabizwa ngokuthi isayithi. I-Wireless Access Point (AP) : Umdali wenethiwekhi engenantambo kanye nendawo emaphakathi yenethiwekhi. Irutha emaphakathi engenantambo esetshenziswa ekhaya noma ehhovisi ine-AP eyodwa.
Okungenhla yi-Shenzhen HDV Phoelectron Technology Ltd. ukuletha amakhasimende mayelana nesihloko sesethulo esithi "WIFI technology Overview", futhi inkampani yethu iwukukhiqiza okukhethekile abakhiqizi benethiwekhi yamehlo, imikhiqizo ehilelekileI-ONUuchungechunge (OLT I-ONU/ACI-ONU/CATVI-ONU/GPONI-ONU/XPONI-ONU), uchungechunge lwemojula ye-Optical (i-optical fibre module/Ethernet optical fibre module/SFP optical module),OLTuchungechunge (OLTimpahla /OLT shintsha/ikati elikhanyayoOLT), njll., kukhona ukucaciswa okuhlukahlukene kwemikhiqizo yokuxhumana ngezidingo zezimo ezahlukahlukene zokusekelwa kwenethiwekhi, wamukelekile ukubonisana.
