Ukungasebenzi kahle okululaukwelashwa

izimpawu zokungasebenzi kahle	Ukungasebenzi kahleimbangela
Akukho nkomba kumukeli kanye nomthumeli	Akukho mandla ku-transmitter, amandla okwamukela awaxhunyiwe kahle
Umamukeli akanayo isignali ye-RF	Amabhendi emvamisa yokwamukela kanye neyokudlulisa ahlukile noma awekho ebangeni elamukelekayo
Kukhona isignali yemvamisa yomsakazo, kodwa akukho signali yomsindo	Imakrofoni yokudlulisa ayixhunyiwe noma ukucinana kwesamukeli kukhulu kakhuluokujulile
	Ukungasebenzi kahle kwesekethe yokuqondisa umsindo
	Ukusetha imodi yokuthula
Umsindo wangemuva wesiginali yomsindo mkhulu kakhulu	Ukuphambuka kwemvamisa yokushintshashintsha kokudlulisa kuncane kakhulu, ugesi wokuthola okukhiphayo Izinga liphansi, Noma kukhona isignali yokuphazamiseka
Ukuhlanekezelwa kwesignali yomsindo	Dlulisai-terukuphambuka kwemvamisa yokuguquguquka kukhulu kakhululikhulu, izinga likagesi eliphumayo lomamukeli likhulu kakhulu
Ibanga lokusebenzisa lifushane, isignali ayizinzile	Amandla okusetha i-transmitter aphansi, futhi ukucinana kwe-receiver kujule kakhulu. Ukusetha okungalungile kwe-antenna yokwamukela kanye nokuphazamiseka okukhulu kwebhethri nxazonke.
