I-expander yenethiwekhi sisixhobo esinokwandisa ngokufanelekileyo umgama wothumelo lwenethiwekhi.Umgaqo kukumodareyitha umqondiso wedijithali womnatha ibe umqondiso analog ngomgca womnxeba, isibini ejijekileyo, umgca coaxial usasazo, kwaye emva koko uthobe umqondiso analog kwi network umqondiso yedijithali kwelinye icala.I-extender yenethiwekhi inokwaphula umda womgama wothumelo lwe-Ethernet yemveli ngaphakathi kweemitha ezili-100, kwaye inokwandisa isignali yenethiwekhi ukuya kwi-350 yeemitha okanye nangaphezulu.Yandisa umda womda wothumelo lwenethiwekhi ukusuka kwi-100 yeemitha ukuya kumakhulu eemitha okanye ngaphezulu, kwaye inokuqonda ngokulula uqhagamshelo phakathi kwama-hubs, utshintsho, iiseva, iitheminali kunye neetheminali ezikude.
