WiFi inzvimbo yepasi rose Wireless local area network (WLAN) chiyero, zita rizere Wireless Fidelity, inozivikanwawo seIEEE802.11b chiyero. WiFi pakutanga yakavakirwa paIEEE802.11 protocol, yakaburitswa muna 1997, yakatsanangurwa WLAN MAC layer uye yemuviri layer zviyero. Zvichitevera 802.11 protocol, shanduro dzakawanda dzakasumwa, dzakawanda dzinowanzoita IEEE802.11a, IEEE802.11b, IEEE802.11g, uye IEEE802.11n.
WiFi system kuumbwa:
WiFi kushandiswa kwewaya yekutaurirana tekinoroji kubatanidza zvishandiso zvekombuta
Hunhu hwakakosha hweWiFi LAN: hauchashandise tambo dzekutaurirana kubatanidza makomputa kunetiweki,
Network topology:
WiFi inogona kunetiweki kuburikidza neakasiyana etiweki topology, uye kuwanikwa kwayo uye kuwana network inewo zvayo zvinodiwa nematanho. WiFi isina waya network inosanganisira maviri marudzi etopology: Infrastructure uye Ad-hoc.
Mafungiro maviri akakosha akakosha:
Chiteshi (STA) : Iyo inonyanya kukosha chikamu chetiweki, yega yega terminal yakabatana kune isina waya network (senge laptops, PDAs uye mamwe maturusi ekushandisa anogona kunetiweki), inogona kunzi saiti. Wireless Access Point (AP): Mugadziri wetiweki isina waya uye yepakati node yetiweki. Avhareji isina waya router inoshandiswa mumba kana muhofisi ine imwe AP.
Iyo iri pamusoro iShenzhen HDV Phoelectron Technology Ltd. kuunza vatengi nezve "WIFI tekinoroji Overview" chinyorwa chekutanga, uye kambani yedu inyanzvi yekugadzira yemagetsi ekugadzira network, zvigadzirwa zvinobatanidzwaONUseries (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Optical module series (optical fiber module/Ethernet optical fiber module/SFP optical module),OLTseries (OLTmidziyo /OLT chinja/katsi yemazisoOLT), nezvimwewo, kune zvakasiyana-siyana zvinotsanangurwa zvekutaurirana zvigadzirwa zvezvido zvemamiriro akasiyana ekutsigira network, kugamuchirwa kubvunza.
