Lub network extender yog ib qho cuab yeej uas tuaj yeem txuas tau lub network sib kis tau zoo. Lub hauv paus ntsiab lus yog hloov kho lub network digital teeb liab mus rau hauv lub teeb liab analog los ntawm cov xov tooj, twisted khub, coaxial kab rau kev sib kis, thiab tom qab ntawd demodulate lub teeb liab analog rau hauv lub network digital teeb liab ntawm lwm qhov kawg. Lub network txuas ntxiv tuaj yeem cuam tshuam los ntawm kev txwv ntawm cov tsoos Ethernet kis nrug deb li ntawm 100 meters, thiab tuaj yeem txuas lub network teeb liab mus rau 350 meters lossis ntev dua. Nws txuas ntxiv qhov kev txwv ntawm kev sib kis ntawm lub network los ntawm 100 meters mus rau ntau pua meters lossis ntau dua, thiab tuaj yeem paub qhov kev sib tshuam ntawm hubs, keyboards, servers, terminals thiab tej thaj chaw deb terminals.
