WiFi ke maemo a machaba a Wireless local area network (WLAN), lebitso le felletseng la Wireless Fidelity, le tsejoang hape e le IEEE802.11b standard. WiFi qalong e ne e ipapisitse le protocol ea IEEE802.11, e phatlalalitsoeng ka 1997, e hlalositse maemo a WLAN MAC le maemo a 'mele. Ho latela protocol ea 802.11, liphetolelo tse ngata li hlahisitsoe, tse tloaelehileng ka ho fetisisa ke IEEE802.11a, IEEE802.11b, IEEE802.11g, le IEEE802.11n.
Sebopeho sa sistimi ea WiFi:
WiFi ke tšebeliso ea theknoloji ea puisano e se nang mohala ho hokahanya lisebelisoa tsa khomphutha
Litšobotsi tsa bohlokoa tsa WiFi LAN: ha e sa sebelisa likhoele tsa puisano ho hokahanya likhomphutha le marang-rang,
Netweke topology:
WiFi e ka hokahanngoa ka li-topology tse fapaneng tsa marang-rang, 'me marang-rang a ho sibolla le phihlello le ona a na le litlhoko le mehato ea ona. Marang-rang a WiFi a se nang mohala a kenyelletsa mefuta e 'meli ea topology: Infrastructure le Ad-hoc.
Likhopolo tse peli tsa bohlokoa tsa mantlha:
Seteishene (STA) : Karolo ea mantlha ea marang-rang, terminal e 'ngoe le e' ngoe e hokahantsoeng le marang-rang a se nang mohala (joalo ka lilaptop, li-PDA le lisebelisoa tse ling tsa mosebelisi tse ka hokahanngoang), li ka bitsoa sebaka sa marang-rang. Wireless Access Point (AP) : Moqapi oa marang-rang a se nang mohala le node e bohareng ea marang-rang. Router e tloaelehileng e sebelisoang lapeng kapa ofising e na le AP e le 'ngoe.
