ʻO WiFi kahi maʻamau maʻamau o ka honua Wireless local area network (WLAN), inoa piha ʻo Wireless Fidelity, ʻike ʻia ʻo IEEE802.11b maʻamau. Ua hoʻokumu mua ʻia ʻo WiFi ma ka protocol IEEE802.11, i paʻi ʻia i ka makahiki 1997, wehewehe ʻia ka papa WLAN MAC a me nā kūlana papa kino. Ma hope o ka protocol 802.11, ua hoʻokomo ʻia nā mana he nui, ʻo ka mea maʻamau ʻo IEEE802.11a, IEEE802.11b, IEEE802.11g, a me IEEE802.11n.
ʻōnaehana ʻōnaehana WiFi:
ʻO WiFi ka hoʻohana ʻana i ka ʻenehana kamaʻilio uila e hoʻopili i nā polokalamu kamepiula
ʻO nā hiʻohiʻona koʻikoʻi o WiFi LAN: ʻaʻole hoʻohana hou i nā kaula kamaʻilio e hoʻopili i nā kamepiula i ka pūnaewele,
Topology pūnaewele:
Hiki ke hoʻopili ʻia ʻo WiFi ma o nā topologies pūnaewele like ʻole, a ʻo kāna ʻike ʻana a me ke komo ʻana i ka pūnaewele aia nō hoʻi kāna mau koi a me nā pae. Loaʻa i nā ʻupena uila WiFi ʻelua ʻano topology: Infrastructure a me Ad-hoc.
ʻElua mau manaʻo kumu nui:
Station (STA): ʻO ka mea nui loa o ka pūnaewele, kēlā me kēia pahu i hoʻopili ʻia i ka pūnaewele uea (e like me nā laptops, PDA a me nā mea hoʻohana ʻē aʻe i hiki ke hoʻopili ʻia), hiki ke kapa ʻia he pūnaewele. Wireless Access Point (AP) : ʻO ka mea nāna i hoʻokumu i kahi pūnaewele uila a me ka piko waena o ka pūnaewele. Hoʻokahi AP o ka mea hoʻohana kelepona ʻole ma ka home a i ʻole ke keʻena.
ʻO ka mea i luna ʻo Shenzhen HDV Phoelectron Technology Ltd. e lawe mai i nā mea kūʻai aku e pili ana i ka "WIFI technology Overview" ʻatikala hoʻolauna, a ʻo kā mākou hui kahi hana kūikawā o nā mea hana ʻenehana optical, nā huahana i pili.ONUmoʻo (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), ʻO ka moʻo moʻokala ʻokoʻa (mode fiber optika/Module fiber optical Ethernet / module optical SFP),OLTmoʻo (OLTmea lako /OLT hoʻololi/pōkole optikaOLT), a me nā mea ʻē aʻe, aia nā ʻano kikoʻī o nā huahana kamaʻilio no nā pono o nā hiʻohiʻona like ʻole no ke kākoʻo pūnaewele, e ʻoluʻolu e kūkākūkā.
